H2Flow - Model Gamma Series -Dissolved Air Flotation (DAF) System

SHARE

The Gamma flotation units are designed to treat wastewater with light to medium solids loading and very high flows. The capacity of the Gamma units range from 990 usgpm to 2425 usgpm (225 to 600 m3/hr). The Platepack System multiplies the separation surface for effective separation, making it possible to treat a large amount of wastewater in a small footprint. The solids float to the surface and are collected by the sludge rake mechanism and transported to the sludge hopper with a low friction scraper system. The collected sludge is transported with a sludge pump to a sludge tank or dewatering.
