Coagulation and flocculation, enviro concepts

Dissolved and suspended particles are present in most industrial wastewater. To remove these particles from the water, Coagulation and Flocculation processes can be used. Coagulation-Flocculation is a chemical water treatment process often applied prior to sedimentation and filtration. Enviro Concepts provides proven Pre-Coagulation and Pre-Flocculation auxillary equipment for a wide range of water and wastewater treatment applications.

Applications

Enviro Concepts Chemical Mixing and Dosing equipment is used prior to solid-liquid separation processes in our waste water treatment plants
like the Dissolved Air Flotation (DAF) or the Lamella Clarifier. Some of the applications where coagulation and flocculation systems are used:

  • Potable Water Pre-Treatment
  • Vehicle and Equipment Wash
  • Commercial Trade Waste
  • Industrial Waste Water
  • Council Waste Water
  • Bore water and Sea water Clarification

Static Mixers
(Clear PVC Static Mixer – 1.5 to 230 LPM)

Enviro Concepts’ clear PVC static mixers are designed for quick blending and integration of coagulants and flocculants into the wastewater
by imparting turbulance. This is done over a short pipe distance using 6 to 12 mixing elements which also allows for visual inspection of the mixing process.
  • PVC clear pipe
  • 6 or 12 mixing elements
  • Edge sealing and Male NPT threads

Pipe Flocculators
(Flocculation Pipe Mixers)

Enviro Concepts pipe flocculators are hydraulic flocculators that use the natural turbulence generated by the water flow to mix the wastewater
with the injected coagulants and flocculants.
