YAZD, IRAN

Circulation and treatment of cooling water within four states of the cooling units to cover main demands of IRAN Alloy Steel Complex (IASCO) YAZD-1: 700,000 tons development project. Other parts of the comprehensive water system of the plant include the Treatment of both deep underground water and river water to supply the water demands of IASCO. By Taking advantage of the latest technologies, the plant produces demineralized, industrial, potable, irrigation, firefighting water, and reuse wastewater.
