Clarification
Leopold Clari-DAF® System (concrete tank)
A concrete tank system that is built on-site. The concrete tank will be poured for the rapid mix, flocculators, dispersion and reaction zones, sludge collection channel, and clarified water channel. ITT WWW Leopold would provide engineering design, the rapid mixer, flocculators with VFDs, effluent laterals, mechanical sludge removal, and complete recycle system with pumps, valves, air compressor, saturator tank and dispersion header, as well as instruments and controls. Can be engineered to specific design requirements for mixing time, loading rate, or recycle rate. Provided for systems that require flow above 2 MGD (300 m3hr).
Leopold Clari-DAF® System (steel tank)
ITT WWW Leopold provides a steel tank system to be installed on a concrete pad with the recycle system shipped separately and connected on site. The total system is comprised of a compartmented tank, rapid mix, flocculators, dispersion and reaction zones, effluent laterals, mechanical sludge removal, and complete recycle system with pumps, valves, air compressor, saturator tank and dispersion header, as well as instruments and controls. Can be engineered to specific design requirements for mixing time, loading rate, or recycle rate. Available in standardized design and flow capacity below 2 MGD (300 m3hr).
Clari-VAC® System
A floating sludge collector installed in rectangular wastewater secondary clarifiers. It operates on the principle of siphon where the collection header vacuums the solids that have been naturally settled on the tank floor. The sludge is siphoned into a separate trough where it is pumped to waste or returned to the activated sludge biological process. There are no moving parts under water and all parts except the drive are nonferrous metals to minimize corrosion potential.
