WATER CLARIFICATION
Effective clarification insures that the solids come out of the process where they should. Whether your needs are primary, secondary, tertiary or high rate clarification, new or retrofit,standard or high rate, WE can supply you with the Technology you need. After the fact improvements in your existing clarifiers? Stamford baffles help eliminate density currents that can cause washouts by redirecting density currents back into the sludge blanket. Algae building consuming all of your manhours and driving you crazy? Clarifier CleanSweep has your back. Slipstream or peak flow process problems can benefit tremendously from the Kruger Actiflo high rate ballasted clarifier (with up to 30 times smaller footprints than a conventional clarifier) and the variant options such as those which provide biological contact time in addition to clarification.
LAMELLA (PLATE) CLARIFIERS
Lamella clarifiers are used for gravity separation of settlable solids in water where space is at a premium or is the process equipment of choice. Whether known as inclined plate clarifiers, plate settlers or tube settlers, a lamella clarifier multiplies (stacks) its smaller footprint to provide the necessary surface area to satisfy the required surface loading rate (settling rate) for effective solids separation. Inclined stacked plates or tubes are used commonly for this purpose. With an angle of inclination of about 60 degrees, settled solids are automatically sloughed off and are collected in a hopper shaped trough below. Influent feed flow is distributed upwards and uniformly through the media in a counter-current pattern.
The Tenco Hydro Clari-Pac G typically utilizes a triangular cross-section thermoplastic tubular media molded in modular packs and contained in removable stainless steel frames. Other units using parallel plates have also been supplied. Media volume is determined by the feed flow and appropriate design settling rate. For optimum performance, the water may require chemical conditioning and flocculation. The necessary mixing compartments are usually integrally fabricated with the clarifier. Chemical feed equipment, instrumentation, controls and sludge transfer pumps are preassembled for a complete process module. Optional sludge screw conveyors are offered for larger flow modules.
