A method which clarifies the water to ensure it is clear and colourless. Clarification causes a precipitate to form in the water which can be removed using simple physical methods. Initially the precipitate forms as very small particles but as the water is gently stirred, these particles stick together to form larger particles.
Water exiting the flocculation basin may enter the sedimentation basin. It is a large tank with slow flow, allowing floc to settle at the bottom. As particles settle at the bottom of the basin, a layer of sludge is formed on the floor of the tank. This layer of sludge is removed and treated. In many cases the tank can be equipped with mechanical cleaning devices.
Accomplished by both filtering out harmful microbes and by adding disinfectant chemicals in the last step in purifying drinking water.
After separating the floc, the water is filtered as the final step to remove remaining suspended particles and unsettled floc. TES have a vast knowledge of a variety of filter methods to include rapid sand filters, membrane filters and pressure filters with various types of media.
Ultrafiltration membranes use polymer membranes with chemically formed microscopic pores that can be used to filter out dissolved substances avoiding the use of coagulants. The type of membrane media determines how much pressure is needed to drive the water through and what size of microorganisms can be filtered out.
Water treatment chemical dosing systems are manufactured depending on water quality.
