Zero Liquid Discharge (ZLD) Systems

Modification of Water treatment and desalination technologies and development of new technologies for reducing the inevitable production of byproducts, namely wastewater, have preoccupied experts for years. New technologies produce fewer wastewaters and use residual salts as a byproduct. Water crisis, recycling limitation, economic parameters and effluent disposal problems such as footprint limitation or environmental preventions justify utilization of zero liquid discharge (ZLD) systems. ZLD systems capacity is 25 to 5000 m3/d.

Having conducted comprehensive studies on the ZLD systems and negotiations with companies active in this field around the world, our company is proud to develop water treatment and desalination technologies as the only possessor of technical know-how in design and construction of ZLD systems in Iran.

ZLD System Applications

• Treatment of wastewater from NF/RO,
• Treatment of wastewater from boilers, cooling towers, softeners,
• Treatment of wastewater from oil, gas, refinery and petrochemical industries,
• Treatment of wastewater from power plants and FGD industries,
• Treatment of wastewater from pharmaceutical and chemical industries,
• Treatment of wastewater from mines,
• Treatment of wastewater from different industries (pulp and paper, textile, etc.),
• Very high TDS wastewater treatment.

ZLD System Features

• Drinking and industrial water production,
• Effluent flow and disposal cost reduction,
• High recovery and simple performance,
• Fewer footprints for effluent disposal especially in the case of evaporation ponds,
• Effluent conversion to marketable products and cost reduction.
