3,000 m³/day Industrial Wastewater Reuse Ultrafiltration

📌 Project Quick Overview Client: Chemical industry in Iran  Capacity: 3,000 m³/day (125 m³/hr) Application: Detergent & Chemical Plant Wastewater Reuse (UF Pretreatment for RO) Core Technology: PVDF Hollow Fiber Ultrafiltration (UF) Membrane System Key Outcome: SDI < 2.5, Turbidity < 0.5 NTU, 92% System Recovery Rate, 3,000 m³/d Fresh Water Saved   1. Project Background & Customer Challenge   Founded in 1982, The customer is a premier manufacturer of hygiene and industrial chemical products in Iran. With expanding production capacity and severe local water scarcity in Tehran, reducing freshwater consumption and achieving sustainable wastewater recycling became a critical strategic objective.   The client faced significant operational and environmental challenges:   High Raw Wastewater Impurities: High turbidity (≤50 NTU) and TSS (≤50 mg/L) made direct recycling impossible.   High Risk of RO Membrane Fouling: Without robust pretreatment, downstream Reverse Osmosis (RO) membranes suffered rapid scaling, biofouling, and high replacement costs.   Upstream Oxidant Hazards: The process required upstream Ozonation, demanding UF membrane materials with exceptional oxidant and chemical tolerance.   2. The Integrated Solution: Pretreatment + UF + RO Dual-Membrane Process   To overcome water-stress challenges and protect downstream investment, Hinada engineered a complete, fully automated skid-mounted Industrial Ultrafiltration (UF) System as the central protection barrier for the RO unit.   Process Flowchart: Feed Water → Sand Filter → Self-Cleaning Filter → Ozonizer → Hinada PVDF UF System → RO System → Reclaimed Water     Key Technical Parameters :     Technical Features Key Features of the Hinada UF System :    The Hinada Industrial UF System combines advanced membrane technology with automated process control to ensure reliable long-term performance.     Operational Performance :   The system was officially commissioned in April 2024 and has been operating at or above design expectations:     3. Customer Benefits  The Hinada UF System delivers measurable operational and environmental benefits.   Reuses approximately 3,000 m³ of industrial wastewater every day   Significantly reduces freshwater consumption   Protects downstream RO membranes   Extends RO membrane replacement intervals   Reduces chemical cleaning frequency   Lowers operating and maintenance costs   Supports environmental compliance   Improves sustainable manufacturing performance   4. Why choose Hinada PVDF Ultrafiltration System?   Superior RO Protection: Consistently delivers SDI < 2.5 and turbidity < 0.5 NTU, dramatically lowering RO membrane biofouling and extending RO replacement cycles.   Advanced PVDF Hollow Fiber Membrane: Features outstanding mechanical strength, anti-fouling performance, and superior tolerance to residual ozone and aggressive chemical cleaning reagents.   Fully Automated PLC Control: Smart automated backwashing and CIP (Clean-in-Place) routines eliminate manual intervention and lower O&M labor costs.   Compact Modular Skid: Pre-assembled, factory pressure-tested, and skid-mounted for fast on-site positioning and installation.   5. On-Site Delivery, Commissioning & Market Impact   Delivered and commissioned in April 2024, Hinada provided comprehensive end-to-end technical support, including on-site installation guidance, PLC system integration, and operator training in Tehran.     Commercial Impact & Follow-up Cooperation:   Impressed by the operational stability and water clarity of the Behdash facility, a neighboring industrial plant visited the site. Impressed by the system's performance, the new client subsequently awarded Hinada a larger-scale 8,500 m³/day Industrial UF System contract.     6. Client Testimonial "The UF system has been operating with excellent stability, and the permeate quality consistently meets the feed water requirements for our RO system, ensuring long-term reliable operation of the downstream RO unit. Throughout the project, Hinada's team demonstrated professional technical capabilities and strong service commitment."   — Project Manager, Behdash Chemical .   📩 Need a Customized Industrial UF System for Your Project?   Whether you need RO pretreatment, membrane replacement, or a custom industrial water recycling plant, Hinada engineers are ready to assist.   Contact our engineering team today for a free design proposal and quote!
