River Water Treatment Systems

Integrated Coagulation, Clarification and Membrane Clarification Against High Turbidity

River and stream waters present acute engineering challenges due to extreme seasonal swings in turbidity, heavy silt, suspended clay, and organic runoff during heavy rainfall. EF Aqua builds multi-stage treatment trains featuring coarse intake screening, automated coagulant/polymer dosing, high-rate lamella plate clarifiers, quartz sand filters and polishing ultrafiltration (UF).

Consistently produces ultra-clean process water (turbidity < 0.1 NTU, SDI < 3.0) ready for industrial steam generation, manufacturing processes, or municipal drinking networks.

Advantages & Features

  • Robust performance under extreme turbidity peaks (2,000+ NTU) and seasonal flow swings
  • Lamella separator tube bundles providing maximum settling rate in minimal footprint
  • Automated coagulation (PAC / FeCl₃) and polymer flocculant preparation & dosing
  • Multi-barrier train: Coarse screen + Lamella Clarifier + Sand Filter + UF Membrane
  • Guaranteed filtrate SDI < 3.0 protecting downstream reverse osmosis membranes
  • Pneumatic automated bottom sludge purge and PLC-controlled continuous operation
