Zero Liquid Discharge (ZLD) is an advanced wastewater treatment process that ensures no liquid waste leaves your facility, helping industries comply with strict environmental regulations while promoting water sustainability. At Ocean Envirotech LLP, we provide fully integrated ZLD systems that are efficient, scalable, and tailored to your industry needs.
A Zero Liquid Discharge system recovers and recycles nearly all wastewater by combining various treatment technologies, including:
Pre-treatment & clarification
Reverse Osmosis (RO)
Evaporation & Crystallization
Thermal or Mechanical Vapor Recompression (MVR)
The result? Treated water for reuse and solid waste for safe disposal—with zero liquid effluent discharge to the environment.
A Zero liquid discharge facility (ZLD), is an industrial plant without discharge of waste waters. Target ZLD is normally reached by:
ZLD discharge system overview ZLD technology includes pre-treatment and evaporation of the industrial effluent until the dissolved solids precipitate as crystals. These crystals are removed and dewatered. The water vapor from evaporation is condensed and returned to the process.
