SIRJAN, KERMAN, IRAN

The BARDSIR Rolling Mill Complex is one of the largest and advanced rolling mill factories in the southeast of IRAN, to build Simple and ribbed rebar with capacity of 500,000 tons per year by the hot rolling method. ABSUN PALAYESH Engineering Company has designed and constructed the comprehensive industrial utility project for the BARDSIR Complex as an EPC project with the aim of industrial water production, water cooling and wastewater reuse. The approach of project were “water resources management”, “reduction of water loss” and “protecting the environment of BARDESIR desert region”

The industrial water treatment plant (WTP) and water circulation plant (WCP) with a total capacity of 57,840 m³/d includes the set of direct and indirect cooling towers; with the capacity of 47,040 and 10,800 m³/d, respectively

Replacement of conventional filtration systems (e.g. Sand Filters and activated Carbon Filters) with automatic self-cleaning filters (for the first time in IRAN) is the innovative features of this project. This feature not only increases the efficiency of the treatment process and extends the lifespan of the system, but also significantly reduces the investment and operating costs.

The water treatment system, direct and indirect cooling towers, chemical injection dosing packages, pumping stations, self-cleaning filters, buildings and pipelines, storage tanks, sedimentation and thickening units, medium and low voltage electrical systems, industrial automation & control systems, and instrumentation & analyzers are the main sections of the WCP plant.

The main sections of the WTP project (make-up water treatment plant for cooling towers) with a capacity of 2640 m³/d include pretreatment system, reverse osmosis (RO) system, drinking water supply system, chemical dosing packages, buildings and pipelines, storage tanks and pumping stations.
