1Zero-liquid discharge (ZLD) is a water treatment process in which all wastewater is purified and recycled; therefore, leaving zero discharge at the end of the treatment cycle. Zero liquid discharge is an advanced wastewater treatment method that includes ultrafiltration, reverse osmosis, evaporation/crystallization, and fractional electrodeionization.

Aquatech has an unparalleled depth of experience in zero liquid discharge (ZLD), which include more than 160 installations, including stand-alone thermal/evaporative processes, membrane processes, or hybrid systems.
