1. After the successful construction and operation of Phase I, the contract for the second phase of the desalination plant was won in a separate tender.
2. Phase I process: The feed water is supplied from the Persian Gulf via a direct intake system. After being dosed with a flocculant, it enters into gravity sand filters. The filtrate is stored in a tank, from where it is directed to cartridge filters and the SWRO units via a pumping station. The permeate from the RO units is transferred to a concrete tank by a pump station and transfer pipeline, and subsequently enters the Chabahar and Konarak water distribution network.
3. Main components: Direct intake system and piping, gravity sand filters, filtered water pump station and reservoir tank, chemical dosing unit, cartridge filters, high pressure pumps, pressure vessels and membranes, storage tanks, CIP unit, permeate water pumping station and pipeline.
4. Associated companies: The design and equipment are supplied by Axiom, Austria, and B2A, Austria. All other endeavors are carried out by NVCo.
