Solid Contact Clarifiers: MC ClariFlow

MC ClariFlow solids contact clarifiers feature internal slurry recirculation and positive slurry removal. In the MC, previously formed floc particles are recycled by an internal pump and mixed with the raw water in a central ClariFlow inlet. The ClariFlow is a controlled energy inlet which blends the flow streams and sets up the energy required to produce the gentle turbulence and rotation necessary for flocculation within the floc skirt.

Due to the conical shape of the floc skirt, this energy decreases with increasing depth permitting floc growth and settling beyond the skirt. Scraper arms provide positive slurry removal and multiple, radial effluent troughs (with overflow weirs or submerged orifices) provide the required weir rates. ClariFlow units are available in either pier or bridge-supported designs.

MC ClariFlow solids contact clarifiers are applied to softening and turbidity removal applications. MC units do not require external slurry recirculation.

Solid Contact Clarifier: UniMix Clarifiers

Type UC UniMix clarifiers are specially designed for flocculation and clarification in a single tank. UniMix flocculators located within the large diameter influent well provide low energy flocculation for agglomeration and removal of fine solids.

The variable speed UniMix units permit adjustment of mixing level to meet changing conditions and provide maximum flocculation and clarification efficiency. UniMix clarifiers can be fitted with ClariFlow inlets to prevent short circuiting and assist in promoting flocculation by causing increased floc particle collisions, and a more settleable slurry. UniMix clarifiers are available in either bridge-supported, C type, or pier-supported RS type designs recirculation.
