Effluent Polishing

The most cost-efficient technology for effluent filtration

Hydrotech disc filters provide an excellent fixed barrier in the industrial wastewater treatment process, helping customers comply with chemical oxygen demand (COD), total suspended solids (TSS), and phosphorus discharge limits.

Hydrotech developed disc filter technology for the effluent polishing market, a great advance on conventional sand filters. Disc filters are still considered the most cost-effective technology for tertiary treatment, with Hydrotech leading technological development.


Key benefits

  • Over 2,000 filters installed world-wide
  • Cost-effective upgrade from conventional sand filters
  • 80% footprint reduction compared to conventional treatment
  • Flexible, modular design
  • 50-90% SS reduction without upstream chemical dosing

MBBR Effluent Filtration

The MBBR (Moving Bed Biofilm Reactor) treatment is a unique solution for effluent filtration and a co-creation between Hydrotech and MBBR.

It offers a compact, low CAPEX solution for wastewater treatment. Food and beverage, oil and gas customers use it to reduce COD in water before discharge. Mining customers see the possibilities of nitrifying explosive residues in water.

Key benefits

  • Low TSS in filtrate < 10 mg/l
  • Cutting edge technology
  • One package, two compact technologies that minimize total footprint
  • Optimal upgrade from activated sludge plant for higher capacities
