A Zero Liquid Discharge plant recovers essentially all the water from an effluent stream for reuse and leaves the dissolved solids as a dry, handleable solid. Getting there reliably depends on sizing the train for the salt load, not just the water load.
Key features
- Pre-treatment, RO concentration, evaporation, crystallisation and drying as one designed train.
- Condensate polished to a reuse specification your plant will actually accept.
- Salt recovered dry and handleable, with disposal or reuse route considered from the start.
- Designed against your consent conditions and audited against them after commissioning.
ZLD schemes fail more often from optimistic salt assumptions than from anything else. We size the crystalliser and dryer on the real dissolved solids figure and state the utility consumption you will have to live with.
