How a Dissolved Air Flotation (DAF) System Works for Wastewater First and foremost, a Dissolved Air Flotation (DAF) system is a highly efficient water clarification technology. Its primary purpose is to separate suspended solids (TSS), fats, oils, grease (FOG), and other low-density particles from a liquid stream.   In essence, a DAF system is an important part of many Wastewater Treatment Plant (WWTP) pretreatment stages. It tackles problematic contaminants such as high TSS levels and fats, oils, and grease (FOG) at an early stage. By removing these pollutants early, a DAF system can significantly reduce the load on downstream biological treatment processes, help optimize chemical consumption, and improve the overall performance of the wastewater treatment process. The DAF process can be broken down into four essential stages: ⚙️ 1. Chemical Coagulation and Flocculation (Pretreatment) Before the wastewater enters the main DAF tank, coagulants such as aluminum or iron salts and flocculants such as polyelectrolytes are typically added. These chemicals neutralize electrical charges and cause fine suspended particles and colloidal matter to bind together, forming larger, fluffy agglomerates called “flocs.” This step is crucial because larger flocs are much easier for the microbubbles to attach to during the flotation process. 💨 2. Dissolution and Release of Air (Bubble Generation) This is the heart of the DAF system — creating a large number of extremely fine bubbles. Dissolution (Pressurization) A portion of the clarified effluent or clean water is diverted into a pressure vessel called the saturation tank or air-dissolving tube. Compressed air is injected into this stream under pressure, typically around 4–6 bar. At this elevated pressure, a significant amount of air dissolves into the water, forming a pressurized, air-rich solution. Release (Depressurization) The pressurized, air-rich water is then discharged through special pressure-release nozzles into the main DAF flotation tank, which is normally at atmospheric pressure. The sudden pressure drop causes the dissolved air to come out of solution and form a large number of microscopic bubbles, typically around 20–40 micrometres in diameter. These microbubbles provide the flotation force required for efficient solid-liquid separation.   ⬆️ 3. Bubble Attachment and Flotation (Separation) In the contact zone of the DAF tank, the released microbubbles mix with the chemically pretreated wastewater. The microbubbles attach to the surfaces of flocs, oil droplets, and other suspended particles. Once attached, the overall density of the bubble-particle agglomerates becomes lower than that of water, causing them to rise to the surface under buoyancy. This creates a floating layer of sludge, commonly called the “float” or “scum,” on the surface of the DAF tank. At the same time, the clarified water remains below the floating layer and moves toward the treated-water collection area.   🧹 4. Sludge Skimming and Collection (Final Clarification) Sludge Skimming The accumulated floating sludge layer is continuously or intermittently removed from the surface by chain-driven or spiral skimmers. The collected sludge is directed into a sludge trough and can then be sent for further sludge dewatering, treatment, or disposal, depending on the project requirements. Clear Effluent Withdrawal The clarified water remains in the lower portion of the flotation tank. It is collected uniformly through a system of collection pipes or launders and discharged from the DAF unit. Depending on the overall treatment process, the clarified effluent can then proceed to biological treatment, MBR, UF, RO, or other downstream treatment processes, or be reused when the required water quality is achieved. 💡 Key Advantages and Typical Applications DAF is especially effective for contaminants whose density is close to or less than that of water, including: Fats, oils, and grease (FOG) Suspended and colloidal solids Algae and fibers Emulsified oils Other low-density particles With appropriate chemical conditioning and proper system design, DAF can achieve high removal efficiency. Actual performance depends on wastewater characteristics, chemical dosage, hydraulic loading, air-to-solids ratio, and overall process design. Common Applications Include: Industrial wastewater – food processing, dairy, meat processing, pulp and paper, petrochemical, and metal finishing industries. Municipal wastewater – as a primary treatment step or for sludge thickening. Drinking water treatment – for removing algae, turbidity, and other suspended particles. Oil-water separation – for applications such as refinery and marine wastewater treatment. In summary, a Dissolved Air Flotation (DAF) system combines chemical conditioning, pressure-dissolved air, and physical flotation to provide a robust and widely adaptable solution for solid-liquid separation in wastewater treatment. The effectiveness of DAF makes it an important pretreatment technology for many industrial wastewater treatment applications, particularly where high levels of TSS, oil, grease, and floating or colloidal solids need to be removed before downstream treatment.

From Sand Filtration to Automated UF: Upgrading a 4,300 m³/day Water Treatment System How an existing water treatment system was upgraded with an automated ultrafiltration solution to achieve more stable water quality and a more compact operation.   When Traditional Filtration Is No Longer Enough Caption :  Project site at a Biosafety Industrial ParkFor large residential water treatment systems, stable water quality is just as important as treatment capacity.   In this project, the existing treatment process relied mainly on conventional filtration. However, water quality fluctuations and algae-related contamination created challenges for stable downstream operation.   Instead of simply adding another conventional filtration stage, the project required a more reliable and automated filtration solution. The goal was clear: improve filtration performance while making the system easier to operate and manage. The Upgrade: From Conventional Filtration to UFCaption :  Existing sand and carbon filtration equipment at the project site Hinada upgraded the existing treatment process with an Ultrafiltration (UF) membrane system. The UF system uses hollow fiber membranes with micropores to physically separate suspended solids, colloids, bacteria and other contaminants from the feed water. Compared with conventional filtration, UF provides a more consistent physical barrier and produces a more stable filtrate for downstream treatment. The upgraded system was designed around three key requirements: More stable water quality Higher level of automation Better use of available space This made UF a practical choice for upgrading the existing treatment system without relying solely on conventional filtration.       Caption :  Integrated UF equipment designed for reliable and automated operation A More Compact and Automated UF System   One of the key considerations was not only treatment performance, but also how the new system would operate in the existing facility.   Hinada designed the UF system with an integrated skid-mounted configuration, combining membrane modules, piping, valves, instruments and control components into a compact arrangement.   The system also incorporates PLC-based automatic control, reducing the need for frequent manual intervention and making daily operation easier for the plant team.   The optimized layout reduced the required floor space by approximately 30%, while maintaining the required treatment capacity.   How the UF System Works   The core of the system is the PVDF hollow fiber UF membrane.Caption :  Hollow fiber ultrafiltration membranes use fine pores to separate contaminants from water   Feed water enters the membrane modules under pressure. Water passes through the microscopic membrane pores, while larger suspended particles, colloids and microorganisms are retained.The overall process integrates: Pre-filtration → UF Membrane Filtration → Automatic Control → Treated Water Caption :  Engineering drawings showing the UF system layout and process design  The system was also integrated with the existing treatment equipment, allowing the upgrade to work as part of the overall water treatment process rather than as an isolated unit. Designed for Large-Scale Residential Water Supply The upgraded system was designed to support water treatment for a residential community serving more than 20,000 residents. Key project parameters include: These parameters demonstrate that the project was not simply a membrane replacement, but a system-level upgrade focused on reliability, automation and space efficiency. The Result: More Reliable Filtration, Easier Operation By replacing the limitations of conventional filtration with an automated UF membrane process, the upgraded system provides a more consistent filtration barrier and better control of treated water quality. The project demonstrates an important approach for existing water treatment plants: When conventional filtration can no longer provide the stability required, upgrading the filtration stage can be more effective than simply expanding the existing process. For facilities facing similar challenges, an appropriately designed UF system upgrade can improve filtration performance while also reducing operational complexity and equipment footprint. Looking for a UF System Upgrade? Whether you are building a new water treatment plant or upgrading an existing filtration system, the right membrane configuration depends on your feed water, treatment capacity and required water quality. Hinada provides customized UF membrane systems and water treatment solutions for residential, municipal and industrial applications.     Have an existing filtration system that needs upgrading?

A real-world case study on how Hinada engineered a 2,400 m³/day dual-stage (Sand Filter + PVDF UF) seawater treatment system for a shrimp farm in Indonesia   Background & Challenge: Unpredictable Seawater Intake in Indonesia Indonesia is one of the world's premier regions for commercial shrimp farming. However, coastal aquaculture operators face a constant, unpredictable risk: the quality of raw ocean intake water. For a commercial shrimp farming facility in Indonesia, raw seawater was drawn directly from coastal intake points. Over time, the farm’s engineering team encountered severe operational bottlenecks:   High Turbidity & Silt Loads: Coastal tides and heavy monsoon storms frequently spiked suspended solids (TSS) and silt levels, overwhelming standard filtration setups. Biological Outbreak Threats: Invisible marine pathogens, algae blooms, and bacteria bypassed basic filtration, threatening pond biosecurity and increasing shrimp mortality risks. Heavy Maintenance Downtime: Traditional media filters required constant manual cleaning and frequent media replacement due to rapid clogging   To protect their crop yield and ensure continuous daily production, the farm manager partnered with Hinada to design a customized, fully automated seawater treatment facility.   Technical Solution: Dual-Stage Physical Filtration (Sand Filter + PVDF UF) To satisfy the facility's daily demand of 2,400 m³/day (100 m³/h continuous flow) while protecting downstream equipment, Hinada engineered a dual-stage filtration skid: Raw Ocean Intake → Pressure Media Sand Filtration → Hinada PVDF Hollow Fiber UF Skid → Biosecure Shrimp Ponds   1. Primary Pre-Treatment: Media Pressure Sand Filtration The intake raw seawater first enters heavy-duty pressure sand filters. This primary barrier captures large organic debris, shell fragments, sand, and heavy silt, drastically reducing TSS loads before the water reaches the ultrafiltration membranes. Stage 1 Pre-treatment: Heavy-duty media sand pressure filters working alongside the PVDF Ultrafiltration skid.   2. Core Membrane Barrier: PVDF Hollow Fiber UF Skid Clarified water then enters the core Hinada PVDF Hollow Fiber Ultrafiltration Skid. Operating at a continuous design flow rate of 100 m³/h, the UF membranes feature a pore size precision of 0.02 – 0.1 microns, creating an absolute physical barrier that removes >99% of bacteria, colloidal matter, and fine suspended particles.   Full 2,400 m³/day (100 m³/h) Skid-Mounted Seawater PVDF Ultrafiltration System featuring UPVC anti-corrosion piping   3. Heavy-Duty Marine Engineering Operating in tropical, high-salinity marine environments causes rapid corrosion on standard industrial components. Hinada custom-engineered all manifolds, piping, and structural skid frames using non-metallic, seawater-resistant materials (UPVC/HDPE) to guarantee long-term operational durability.   4. PLC Smart Automation & CIP Integration To minimize manual labor costs and prevent membrane fouling, the system is fully automated via an integrated Siemens PLC panel. The skid automatically executes timed backwashing, air-scouring, and Clean-In-Place (CIP) cleaning cycles without disrupting pond supply lines. Automated Siemens PLC control cabinet, clean water storage tank, and distribution pumps ensuring seamless site operations. Engineering Project Specifications Application: Commercial Shrimp Aquaculture Seawater Intake Location: Indonesia Daily Treatment Capacity: 2,400 m³/day Design Flow Rate: 100 m³/h continuous operation Raw Water Source: High-Salinity Coastal Intake Seawater Core Technology: Pre-treatment Sand Filter + Hinada PVDF Hollow Fiber UF Skid Automation Level: Fully Automated PLC Control with Backwash & CIP Functions On-Site Results & Client Feedback Following installation, commissioning, and on-site testing, the 2,400 m³/day seawater UF system was successfully brought online. On-site evaluation and client inspection of Hinada PVDF Hollow Fiber UF modules in Indonesia The operational results delivered immediate value to the farm: Uncompromising Water Clarity: Effluent turbidity remains consistently low (<0.5 NTU), eliminating water quality fluctuations during coastal tides and rainy seasons. Enhanced Pond Biosecurity: Physical removal of microscopic pathogens reduced disease transmission risks, stabilizing overall crop survival rates. Reduced Operational Labor: Automated backwashing routines eliminated manual filter maintenance, lowering daily labor overhead.   Client Feedback: ""Before installing Hinada’s UF system, we struggled with seasonal algae blooms and bacterial outbreaks that wiped out up to 40% of our nauplii batches. Since commissioning in 2022, our intake water has remained consistently crystalclear, and our postlarval health has improved dramatically. The system runs with minimal supervision – the automatic backwash schedule is so reliable that our operators only need to check it once per shift. When we had a minor pressure drop issue during the rainy season, Hinada’s technical team responded within 2 hours via WhatsApp and guided us to resolve it in less than a day. We are now planning our third expansion, and Hinada is our first call. They don't just sell membranes; they understand shrimp biology." — Statement from the owner of Hatchery Manager, CV.

How a Dissolved Air Flotation (DAF) System Works for Wastewater First and foremost, a Dissolved Air Flotation (DAF) system is a highly efficient water clarification technology. Its primary purpose is to separate suspended solids (TSS), fats, oils, and grease (FOG), and other low-density particles from a liquid stream.  In essence, a DAF is the core of many Wastewater Treatment Plant (WWTP) pre-treatment stages. It tackles problematic contaminants like high TSS levels and Fats, Oils, and Grease (FOG) head-on. By removing these pollutants early, a DAF system significantly reduces the load on downstream biological treatment processes, lowers overall chemical consumption, and is often the key to achieving regulatory compliance for the final effluent.The process can be broken down into four essential stages: ⚙️ 1. Chemical Coagulation and Flocculation (Pretreatment) Before the wastewater enters the main DAF tank, coagulants (such as aluminium or iron salts) and flocculants (polyelectrolytes) are typically added. These chemicals neutralise electrical charges and cause fine suspended particles and colloidal matter to bind together, forming larger, fluffy agglomerates called "flocs". This step is crucial because larger flocs are much easier for the microbubbles to attach to later. 💨 2. Dissolution and Release of Air (Bubble Generation) This is the heart of the DAF system – creating a vast number of extremely fine bubbles. Dissolution (Pressurisation): A portion of the clarified effluent (or clean water) is diverted into a pressure vessel called the saturation tank (or air‑dissolving tube). Compressed air is injected into this stream under high pressure (typically 4-6 bar). At this elevated pressure, a large amount of air dissolves into the water, forming a supersaturated dissolved‑air solution. Release (De‑pressurisation): This pressurised, air‑rich water is then discharged through special pressure‑release nozzles into the main DAF flotation tank, which is at atmospheric pressure. The sudden pressure drop causes the dissolved air to come out of solution instantly, forming an enormous number of microscopic bubbles (typically 20–40 micrometres in diameter). ⬆️3. Bubble Attachment and Flotation (Separation) In the contact zone of the DAF tank, the released microbubbles mix intimately with the chemically pretreated wastewater. Because the bubbles have a natural hydrophobic (water‑repelling) tendency, they attach preferentially to the surfaces of the flocs, oil droplets, and other suspended particles. Once attached, the overall density of the bubble‑floc agglomerate becomes less than that of water, causing them to rise rapidly to the surface under buoyancy. This forms a floating layer of sludge (commonly called the float or scum) on top of the tank. 🧹️ 4. Separation Sludge Skimming and Collection (Final Clarification) Sludge Skimming: The accumulated floating sludge layer is continuously or intermittently scraped off the surface by chain‑driven or spiral skimmers and directed into a sludge trough for further dewatering or disposal. Clear Effluent Withdrawal: The clarified, treated water remains in the lower portion of the tank. It is collected uniformly through a system of collection pipes (or launders) at the bottom and discharged from the DAF unit. This effluent can be reused or discharged in compliance with environmental regulations. 💡 Key Advantages and Typical Applications DAF is especially effective for contaminants whose density is close to or less than that of water, such as: Fats, oils, and grease Colloidal solids Algae and fibres Emulsified oils With proper chemical conditioning, DAF can achieve removal efficiencies of 95–99% for these pollutants. Common applications include: Industrial wastewater – from food processing, dairy, meat packing, pulp and paper, petrochemical, and metal finishing industries. Municipal wastewater – as a primary treatment step or for thickening biological sludge. Drinking water treatment – for removing algae and turbidity. Oil‑water separation – in refinery and marine operations. In summary, the DAF system combines chemical conditioning, pressure‑dissolved air, and physical flotation to deliver a robust, reliable, and widely adaptable solution for solid‑liquid separation in wastewater treatment.
