We VENTILAIR ENGINEERS offered ZERO LIQUID DISCHARGE ETP. zero-liquid discharge is a water treatment process in which all wastewater is purified and recycled; therefore, leaving zero discharge at the end of the treatment cycle. ZLD(ZERO LIQUID DISCHARGE) ETP is an advanced wastewater treatment method that includes ultrafiltration, reverse osmosis, evaporation/crystallization, and fractional electrodeionization.

Zero liquid discharge plant are also termed in this way Zero Liquid Discharge System, Zero Liquid Discharge Plant, zld plant, ZLD evaporator

Zero liquid discharge (ZLD) is an engineering approach to water treatment where all water is recovered and contaminants are reduced to solid waste. While many water treatment processes attempt to maximize recovery of freshwater and minimize waste, ZLD is the most demanding target since the cost and challenges of recovery increase as the wastewater gets more concentrated. Salinity, scaling compounds, and organics all increase in concentration, which adds costs associated with managing these increases. ZLD is achieved by stringing together water treatment technology that can treat wastewater as the contaminants are concentrated.

 

There are a number of benefits to targeting zero liquid discharge for an industrial process or facility:

 

• Lowered waste volumes decrease the cost associated with waste management.

• Recycle water on site, lowering water acquisition costs and risk. Recycling on-site can also result in less treatment needs, versus treating to meet stringent environmental discharge standards.

• Reduce trucks associated with off-site wastewater disposal, and their associated greenhouse gas impact and community road incident risk.

• Improved environmental performance, and regulatory risk profile for future permitting.

• Some processes may recover valuable resources, for example ammonium sulfate fertilizer or sodium chloride salt for ice melting.
