Coagulation

A good coagulation process is crucial for creating flocs which may be separated by either settling, flotation, sand, cloth or disc filtration. A coagulation design using a static, hydraulic or mechanical mixing, based upon the appropriate energy input will achieve the right conditions.

Flocculation

A good flocculation process is essential for building strong flocs which will be easy to separate by either settling, flotation, sand, cloth or disc filtration. A flocculation design requires a combination of an appropriate hydraulic retention time and energy input. Both hydraulic and mechanical flocculators are applied to accomodate this process.

Mixing - Mixing

Both static mixers, mechanical mixers and hydraulic mxing devices are used to mix coagulants with the liquid to be treated. An appropriate design takes into consideration the variations in flows and loads and guarantees the energy input to be sufficient for instanteneous mixing.
