Nettetclarifier units have their origins in the 1940s and 1950s. The two most common applications for the solids CONTACT CLARIFIER are cold lime softening, where the unit is used to maximize the rate of chemical precipitation, and surface water clarification, where the unit is used as an enhanced flocculation device. NettetSince 1976, Ecodyne has supplied hot lime softeners for the removal of hardness, alkalinity, turbidity, oxygen, silica removal and other contaminants in OTSGs and boilers. The unique features of our lime …
NettetLamella clarifiers are supposed to be one of the best possibilities for pre-treatment ahead of membrane filters [6]. Michael [7] illustrated that the surface overflow rate for lamella plate clarifiers is in between (10– 25) m 3/m 2/h. For these overflow rates, the detention time in each lamella clarifier is low, at Nettetwithout polymer in a lime-softening application by recirculating solids through the equipment. In addition to chemical compatibility considerations, the plant would also face operational challenges with a high-rate clarification and softening system. SWTP does not run continuously, but instead operates 8-24 hours a day to match seasonal demands.
NettetBecause the Solids CONTACT CLARIFIER re-circulates previously settled solids many times over, less chemical input is needed and results are superior to conventional treatment methods. Efficient recirculation is provided by a low shear, high volume pumping impeller. This impeller is unique to WesTech and improves on traditional radial impeller ... NettetCOLD & WARM LIME SOFTENERS.

Nettet13. aug. 2012 · Lime softening utilizes the addition of lime (calcium hydroxide) to remove hardness (calcium carbonate and magnesium carbonate) ions by precipitation. Silica particles are absorbed in flakes of magnesium and calcium hydroxides. These flakes (floc) can then be sent to a clarifier or filter where the separated silica can be disposed.
