Zero Liquid Discharge (ZLD)
In today's business environment, companies are beginning to understand the importance of sustainable operations. With the increasing focus on water usage and water discharge, companies are looking for ways to conserve water consumption and reduce discharge to the environment.
Zero-liquid discharge (ZLD) Technologies that eliminate liquid waste discharge and recover water for re-use leaving zero discharge at the end of the treatment cycle. ZLD is a water treatment process in which all wastewater is purified and recycled; therefore, ZLD is an advanced wastewater treatment method that includes ultrafiltration, reverse osmosis, evaporation/ crystallization, and fractional electro deionization.
What is ZLD?
Zero liquid discharge technologies help plants meet discharge and water reuse requirements, enabling your business to: Meet stringent cooling tower blow down and flue gas desulfurization (FGD) discharge regulations Treat and recover valuable products from waste streams Better manage produced water.
ZLD processes can incorporate many different unit operations to eliminate water discharge including cold lime softening, evaporation and crystallization andevaporation. These technologies can deliver valuable financial returns where water conservation and strict permitting regulations have significantly increased the cost of industrial use.
