Clarifier

 

an installation for water purification in a water-supply system. It is used to remove suspended matter and colloidal impurities from water by passing the water upward through a layer of flocculant sediment, which was previously produced by a coagulant. The rate of upward flow in the clarification zone is controlled and ranges from 0.6 mm/sec (relatively clear, low-turbidity water) to 1.4 mm/sec (high-turbidity water), depending on the impurities present. The sediment layer in the clarifier must be at least 2 m thick, and the protective layer of clarified water above it must be at least 1.5 m deep. The excess of sediment is removed through receiving ports or pipes and passes into a sediment compactor, whose volume is 20–40 percent of the clarifier volume.

The fast adoption of the Millad NX 8000 technology over traditional clarifiers has been driven by the material's cleaner, fresher look and inherent sustainability benefits versus competitive products.
A significant fraction of BOD is removed in the oxidation ditch, while TSS is removed in the secondary clarifier. The existing secondary clarifier has a sidewater depth of 9 1/2 feet.
3) Remaining solids are forced to the surface by a dissolved air flotation clarifier. Solids are scraped away, leaving a clarified final effluent, which then becomes influent for PM3.
Before a clarifier was brought back on-line, the area where the splitter box connects with the discharge elbow was cleaned and sealed to improve resistance to corrosive wastewater being distributed from the box.
Depending on the specific product requirement and end user needs, Westfalia can supply a clarifier with a solid-wall bowl or one with a self-cleaning bowl to suit the required duty.
A sidestream of clean hot water from the clarifier is discharged at a rate of 45 gal/min to the sanitary sewer for control of dissolved solids in the water system.

A leading South Coast fish producer is significantly reducing the cost of its wastewater disposal, thanks to Salsnes Clarifier, which is available exclusively in the UK from Vexamus Water.
The order includes an Ultra-V[TM] pressure screen, a Float Purger[TM] stock cleaning system, XTREME[TM] reverse cleaners, XX-Clone[TM] through-flow cleaners, and a flotation clarifier. This equipment will be components of a new 250 tons/day production line that the mill is adding to increase capacity.
