HINADA Water Treatment Tech Co., Ltd. (HINADA) is a leading Chinese manufacturer specializing in daf filtration systems, renowned for their superior oil removal capabilities across industries such as oil refining, food processing, marine, and textiles. DAF (Dissolved Air Flotation) systems use microbubbles to efficiently separate oil and suspended solids, achieving up to 99% oil & grease removal—significantly outperforming traditional gravity or API separators. HINADA’s modular, scalable designs ensure compatibility with diverse applications and compliance with global discharge standards. The company also provides integrated wastewater treatment solutions, including MBR membrane and UF system modules, for advanced water reuse and polishing. By offering tailored engineering support, pilot testing, and comprehensive after-sales service, HINADA addresses the full spectrum of buyer needs—from technical reliability and compliance to cost-effectiveness and operational support. For buyers seeking robust, proven, and flexible oil removal solutions with long-term value, HINADA’s DAF filtration systems are the optimal choice, supported by a global track record and professional engineering expertise.
Leveraging DAF Filtration Systems for Effective Oil Removal
In the field of industrial wastewater treatment, the challenge of efficiently removing oil and suspended solids is universal. HINADA, the professional abbreviation for Hinada Water Treatment Tech Co., Ltd., stands at the forefront of this sector by delivering DAF filtration systems and dissolved air flotation systems renowned for their superior oil removal capabilities. As a leading Chinese manufacturer and supplier, we understand that industrial buyers, environmental engineers, and procurement specialists demand proven performance, value, and reliability when it comes to oil removal equipment, wastewater treatment solutions, and industrial water filtration solutions.
Why Choose DAF Filtration Systems for Oil Removal?
DAF filtration systems (Dissolved Air Flotation) have emerged as the industry standard for effective oil separation and suspended solids removal from industrial and municipal wastewater. The core principle is the introduction of microbubbles that attach to oil and contaminant particles, causing them to float and be easily separated from water. As a result, DAF systems achieve higher removal efficiencies compared to conventional sedimentation or gravity-based clarifiers. HINADA’s DAF systems are widely applied in oil refinery wastewater treatment, food processing plants, pharmaceutical wastewater treatment, textile industry wastewater treatment, and marine oily water treatment, delivering significant reductions in oil & grease (O&G), COD, and suspended solids (TSS) content.
Key Product Advantages – HINADA DAF Filtration Systems
High Separation Efficiency: DAF technology delivers up to 99% oil and grease removal, far surpassing traditional oil-water separators, gravity separators, or skimmers.
Modular, Scalable Design: From compact DAF units for small-scale industries to large custom-built dissolved air flotation clarifiers, HINADA offers flexible DAF system configurations to suit every application and flow rate.
Low Footprint and Easy Maintenance: Our DAF clarifiers are engineered to maximize throughput in minimal space with simple operation and minimal downtime, making them ideal for retrofits or new installations.
Chemical Optimization Capabilities: Integration with coagulation and flocculation dosing ensures enhanced removal of emulsified oils and fine particles.
Energy Efficiency: DAF systems use less power than many competing technologies, lowering your operational costs while achieving stringent discharge limits.
Targeted Solutions for Industrial Wastewater Treatment Buyers
Buyers and procurement managers understand that every industrial process generates unique wastewater challenges. HINADA’s technical team collaborates closely with clients to offer tailored DAF wastewater treatment systems for specific industries:
Oil Refinery Wastewater Treatment: Our DAF systems are proven in oil refinery applications, where high oil loads and strict effluent requirements demand robust solutions.
Food Processing Wastewater Treatment: Fat, oil, and grease (FOG) removal is critical for compliance and plant operation efficiency. HINADA’s DAF systems efficiently handle dairy, meat, and vegetable oil waste streams.
Textile Industry Wastewater Treatment: Our dissolved air flotation technology excels at removing dyes, fibers, and oils commonly found in textile plant effluent.
Marine Oily Water Treatment: HINADA’s marine DAF systems meet IMO and regional standards for bilge water and shipboard oily wastewater treatment.
Performance and Compliance – Meeting the Most Demanding Oil Discharge Standards
Increasingly stringent environmental regulations worldwide require oil & grease levels in treated effluent to be reduced to below 10 ppm, or even lower for sensitive environments. HINADA’s DAF filtration systems are fully engineered to meet or exceed global compliance standards, including EPA, EU, and China’s Ministry of Ecology and Environment regulations.
Our systems are certified and tested for consistent performance, with reference installations across the globe demonstrating O&G removal efficiencies up to 99% and TSS reduction to below 5 mg/L.

Comparing DAF with Other Oil Removal Technologies
When selecting an oil removal solution, buyers often compare DAF with API separators, gravity oil separators, centrifuges, and membrane filtration systems. While each has merit for specific use cases, DAF technology, as supplied by HINADA, stands out in terms of:
Removal Efficiency: DAF removes both free and emulsified oils, outperforming gravity oil separators and API separators, which struggle with stable emulsions.
Versatility: DAF handles variable loads and diverse contaminants, whereas membrane filtration, while effective, is prone to fouling with high oil concentrations.
Cost-Effectiveness: DAF’s operating and maintenance costs are typically lower than centrifuge or membrane systems, especially for large-scale applications.
Integrated Keywords – MBR Membrane and UF System
In addition to our flagship DAF filtration systems, HINADA offers advanced MBR membrane bioreactors and UF system (ultrafiltration system) solutions for clients requiring even higher levels of water reuse and polishing. Many clients integrate DAF as a primary oil and solids removal step before MBR or UF modules, greatly extending membrane life and reducing overall operational costs.
Procurement Considerations – What Matters to Genuine Buyers?
Experienced buyers know that successful procurement involves more than just price. Critical factors include:
Reliability and Proven Track Record: HINADA’s DAF systems are trusted by hundreds of industrial clients globally. We provide client references, technical data, and performance guarantees.
