SIMPEC RO Double Pass 8000- 160 m³/day

Technical Summary

Industrial Water Treatment Plant – SIMPEC RO Double Pass 8000 44 8

The system is a fully automatic, two-stage reverse osmosis plant for industrial applications with high-purity water requirements. Designed for process water recycling, landfill leachate treatment, biogas and agricultural operations, as well as the food and chemical industries.

The system is pre-assembled on a stainless steel skid and includes all key water treatment components, including chemical dosing, filtration, high-pressure pumps, and automation.

- Pre-filtration with multimedia and cartridge filter
- Automatic pH correction (acid / caustic)
- Dosing station with 3 dosing pumps
- Siemens S7 control system with TP700 HMI
- Integrated CIP cleaning system
- Completely piped and wired (Plug & Play)
- High-grade materials (AISI 304 / 316, FRP)
- Pressure sensors, conductivity probes, flow meters

⚙️ Process Description

Feed & Pre-filtration
Raw water is pumped via a stainless steel pump to a multimedia filter (MMF) to remove suspended solids. This is followed by fine filtration via cartridge filters.

First RO Stage (High Pressure)
Pre-treated water is fed with a 44 kW high-pressure pump into six RO pressure vessels containing a total of 36 membranes.
Result: Permeate with < 1000 µS/cm conductivity.

Second RO Stage (Polishing)
Permeate from stage 1 is further purified in two RO vessels (8 membranes).
Result: Ultra-pure water with conductivity < 100 µS/cm.

Chemical Dosing
Three dosing pumps control:
- Antiscalant / acid in the feed
- NaOH for concentrate pH correction

Automatic Control
All operating parameters (pressure, conductivity, flow, pH, temperature) are monitored via sensors and displayed on the Siemens HMI.
