Primary treatment is a plain screening, sedimentation or flotation process to remove suspended organic and inorganic solids from the sewage. Chemicals are sometimes used to remove finely divided and colloidal solids.
Merges small suspended solids into flocs that the flotation unit can remove from the water.
A dosing system is a system to automate and optimise coagulant dosing in wastewater treatment.
The polymer preparation unit is used to create/ dilute a consistent high quality flocculant solution.
The Dissolved Air Flotation (DAF) units are designed to remove oil, grease, solids and/or flocs from the wastewater which do not have sufficient buoyancy to float.
Separates settable solids.
Separation of oil and suspended solids from refinery and allied water effluents by means of "plate pack" modules, working by gravity separation between spaced corrugated plates, is proven technology.
