Wastewater & Water Reuse
Reclaimed Water Reuse System
Turn treated effluent into reusable process, cooling, flushing and irrigation water.
- Capacity
- 5 – 2,000 m³/day
- Outlet Quality
- GB/T 18920 / GB/T 19923 reclaimed water standards
A reclaimed water reuse system takes secondary treated effluent and upgrades it to a quality suitable for reuse — cooling tower make-up, toilet flushing, floor and vehicle washing, landscape irrigation, or even return to the production process.
The core is a combination of ultrafiltration and reverse osmosis with appropriate pre-treatment and disinfection. For high-salinity effluent, a two-stage RO or RO + evaporation arrangement moves the plant toward zero liquid discharge.
Reuse typically cuts fresh water purchase by 50 %–80 % and reduces the discharge fee at the same time, so the investment normally pays back within one to three years.
Key Features
Why This System Performs
50 %–80 % water saving
Most of the effluent is returned to service, cutting both intake cost and discharge volume.
UF + RO double barrier
Ultrafiltration removes particles and microbes, RO removes dissolved salts and residual organics.
Toward zero liquid discharge
Optional high-recovery RO, evaporation and crystallisation stages for ZLD compliance.
Fast payback
Typical payback of 1–3 years from water purchase and discharge fee savings.
