Water Reuse and Zero Liquid Discharge Pretreatment
Water reuse and zero-liquid-discharge projects depend on stable pretreatment to control suspended solids before membrane, evaporation and crystallization stages. Without reliable filtration, particles can foul membranes, reduce heat-transfer efficiency and increase maintenance costs.
UNITE provides ZLD pretreatment solutions using Automatic Backwash Filters and customized Filtration System Series packages. Our solutions remove suspended solids and process contaminants before sensitive downstream treatment equipment.
Common Water Reuse and ZLD Challenges
Industrial wastewater can contain fine particles, fibers, oil residues and precipitated solids. These contaminants can accumulate in membranes and evaporators, leading to lower efficiency and shorter equipment service life.
A ZLD pretreatment filtration system helps to:
- Reduce suspended solids entering membrane systems
- Minimize membrane fouling and cleaning frequency
- Protect pumps, heat exchangers and evaporators
- Improve water-reuse reliability
- Support efficient salt concentration and recovery
Recommended Filtration Solutions
Automatic self-cleaning filters can provide continuous pretreatment for high-flow systems. Fine filtration equipment can be added where membranes or high-precision treatment stages require cleaner feedwater.
