Description
Our 20000 GPD RO plant produces about 75 cubic metres of purified water per day (around 3.1 m³/h). It is a skid-mounted reverse osmosis system for hotels, labour camps, hospitals and factories that need reliable, low-TDS water from municipal, tanker or brackish well supply.
Each 20000 GPD RO plant is designed from a full water analysis. Feed TDS, silica, iron and temperature in Oman vary widely from site to site, so we size pre-treatment, membrane array and antiscalant dosing to your water, not to a catalogue.
Features of the 20000 GPD RO plant
- Multimedia and activated carbon pre-filters with automatic backwash
- Antiscalant dosing with Emec dosing pump
- 5 micron cartridge filter before the membranes
- Dupont Filmtec membranes in FRP or stainless pressure vessels
- Grundfos multistage high-pressure pump
- PLC or relay control panel with low/high pressure, tank level and conductivity monitoring
- Optional CIP skid, remineralisation, UV and chlorination
