Drinking Water Treatment - Pretreatment: Improve filter runtime, reduce disinfection by products, save operating costs 

Coagulation, flocculation, and clarification are perhaps the most overlooked processes when installing instrumentation in a water treatment facility.

However, every step in the treatment process depends on preceding steps and those steps that follow to make the entire process function effectively.

Measurement is critical at every step to optimis the process and control operational costs. Control dosing of coagulant and save chemical and sludge costs by measuring what you cannot see.
