Frequently Asked Questions

A ZLD system is an advanced industrial water treatment process that purifies and recycles 100% of wastewater, leaving zero liquid effluent discharge into local rivers or soils. Pollution control boards mandate ZLD for high-polluting sectors.

A complete ZLD plant integrates primary ETP, high-recovery RO/Hero membranes, Mechanical Vapor Recompression (MVR) or Multi-Effect Evaporator (MEE), Agitated Thin Film Dryer (ATFD), and crystallizers.

High-TDS concentrate from thermal evaporators is fed into an ATFD or Crystallizer where water is completely vaporized, converting liquid reject into dry, solid salt bags suitable for hazardous waste landfilling or industrial reuse.

Energy is optimized by maximizing RO brine concentration (reducing thermal evaporator feed volume by up to 80%), utilizing MVR compressors, and integrating waste heat recovery exchangers.

OPEX is minimized through effective pre-treatment (preventing scale on evaporator tubes), high-efficiency chemical softening, high-recovery membrane stages, and salt recovery/segregation techniques.
