In the realm of environmental and water treatment, Clar-O-Floc is a term synonymous with efficient and effective clarification. This method, pioneered by Alar Engineering Corp., utilizes a unique combination of chemical flocculation and mechanical separation to remove suspended solids from wastewater. This article will delve into the concept of Clar-O-Floc and explore the design and operation of Alar Engineering's Hopper-bottom clarifier, a key component in this process.
The Science Behind Clar-O-Floc
Clar-O-Floc is a process that combines the principles of coagulation and flocculation. Coagulation involves adding chemicals, often aluminum or iron salts, to destabilize the suspended solids in the wastewater. This destabilizes the particles, allowing them to clump together. Flocculation, on the other hand, utilizes polymers to bind these destabilized particles into larger, more easily settleable flocs.
These flocs then settle to the bottom of the clarifier due to gravity, effectively separating the solid waste from the treated water. This treated water is then discharged, while the settled solids are removed from the bottom of the clarifier, typically for further processing or disposal.
