1. Production process: Raw water is supplied through wells and is transferred to the plant by a 70 km pipeline. It is then stored in a raw water tank and is transferred to sand filters and BWRO units by a pump station and transfer pipeline. The desalinated water from the RO units is then transferred and stored in two 5000 m3/day tanks via a pump station and transfer pipeline and enters Qom's second distribution network.
2. Main components: Feed pump station and raw water transfer pipeline, chemical dosing unit, sand filters, cartridge filters, high pressure pumps, pressure vessels and membranes, PLC system, chemical cleaning unit, storage tanks, permeate water pump station and transfer pipeline. In this project, for the first time, an automated distribution system using rechargeable credit cards was designed and implemented by NVCo throughout the city. This credit-based system may very well be the only one of its kind in the world.
3. Associated companies: The design, commissioning, and operation of the desalination plant as well as the establishment of the transfer and distribution network was carried out by NVCo. The reverse osmosis equipment was supplied by Veolia Water.
