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
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.
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
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.
3. Customer Benefits
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.
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.
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.
"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."
