High-Salt Wastewater Filtration
High-salt wastewater is common in chemical, pharmaceutical, mining, new-energy and industrial production processes. In addition to dissolved salts, these streams may contain suspended solids, crystals, oils, catalyst particles and organic residues.
UNITE provides high-salt wastewater filtration systems for pretreatment before membrane concentration, evaporation, crystallization, reuse or zero-liquid-discharge processes. Effective solids removal helps reduce membrane fouling and improves the stability of downstream separation equipment.UNITE provides brine-filtration systems using Automatic Scraper Filters, Candle Filters and customized treatment skids.
Common High-Salt Wastewater Challenges
High salinity can increase corrosion risk, while crystal formation and suspended solids can cause plugging in pipelines, filters and evaporation systems. Equipment must be selected according to both water quality and long-term operating conditions.
A high-salt wastewater filtration system helps to:
- Remove suspended solids and salt crystals
- Protect membranes, pumps and evaporators
- Reduce fouling and maintenance requirements
- Improve water-reuse and ZLD process stability
- Support salt recovery where required
Recommended Filtration Solutions
Automatic scraper filters and self-cleaning filters are suitable for continuous solids removal. Candle filters and pressure leaf filters can be selected for finer separation or crystal recovery. Corrosion-resistant materials should be chosen according to the wastewater composition.
