DCL-020 High Rate Flash Mixed Polymer Flocculant Lamella Clarifier Water Treatment

What Is Lamella Clarifier

Total Suspended Solids (TSS) will naturally settle over time due to gravity, but this process can be sped up and improved by having an Inclined Plate. Water flows up the plate at a 60° angle. Gravity will force the solids to settle onto the plate. The particles collect on the plates will become heavier and slide back down the plate to the clarifier cone. This process creates a counter flowing pattern, where the solids are seperated from the liquid into two lanes of traffic. The water flows in the upward bound lane, and the sludge flows in downward lane. This method reduces drag and friction creating a faster settling process than if the solids were to settle naturally.

Flocculants and Coagulants are added to improve the settling time. Coagulants neutralize the negative charge particles allowing them to sink faster. Flocculants allow for the small particles to collect and accumulate. This will make the solids heavier and easier to settle.
