The journey

From wastewater to
water for reuse.

Industrial wastewater recycling combines treatment steps. Each one removes or separates a different part of the waste.

  1. Raw effluentThe starting point
  2. ETPEffluent Treatment Plant
  3. MBRMembrane Bioreactor
  4. ROReverse Osmosis
  5. MEEMultiple Effect Evaporator
  6. ATFDAgitated Thin Film Dryer
  7. Recovered waterReady for suitable reuse

This is an example treatment route. A membrane bioreactor (MBR) can form part of an effluent treatment plant (ETP) before reverse osmosis (RO). Your wastewater and intended reuse determine the steps needed.

Industrial water recycling

Treat wastewater.
Put water back to work.

Wastewater recycling can put treated water back into suitable plant operations. We plan water reuse alongside the treatment and handling of leftover sludge, salts and concentrated waste.

Water tests and the requirements of the next use guide the design. Clear water alone does not tell us whether it is suitable.

Explore treatment solutions

  • Recover water

    Prepare treated water for suitable reuse within your operations.

  • Reduce freshwater demand

    Match recovered water quality to the needs of its next use.

  • Manage residual waste

    Plan how to handle the sludge and concentrated waste left after treatment.

Solutions

Water treatment solutions.
Built around your plant.

Compare effluent treatment, sewage treatment and water recovery systems. Each has a different job, so we start with your water quality, daily flow and intended use.
