Multi-media activated carbon filtration system industrial ultrafiltration reclaimed water treatment system STRO Membrane Water Treatment Equipment for 4 Tons per Hour with 45% Water Recovery Rate

Hospital Medical Water System - Medical Laboratory Pure Water Treatment Equipment

Shanghai Tongjie Environmental Technology Co., Ltd., a trusted name in industrial wastewater treatment and membrane separation technology, has successfully commissioned a customized STRO (Spiral Tube Reverse Osmosis) hospital wastewater treatment system for WuXi AppTec's manufacturing site in Singapore.

Designed for a treatment capacity of 4 tons per hour and a water recovery rate of 45%, the system addresses one of the most challenging industrial effluent profiles in the pharmaceutical sector.

• Treatment Capacity: 4 tons per hour
• Water Recovery Rate: 45%
• Handles COD levels up to 500 mg/L
• TDS concentrations reaching 400 mg/L
• Strong alkalinity (pH 13)
• High chloride content resistance

Tongjie Environmental's STRO membrane technology offers a distinct advantage: its patented open-channel, low-fouling flow path design minimizes membrane blockage and enables stable, long-term operation even under extreme water quality fluctuations.
