Dissolved Air Flotation Plants 

Rendertech Dissolved Air Flotation Plants (DAF) provide the solution to many wastewater treatment requirements. They work on the principal of air microbubbles that attach themselves to the suspended contaminants in the wastewater and float them to the surface where they form a sludge layer.  This sludge layer is periodically removed using a slow moving scraper.  Rendertech dissolved air flotation  plants are compact, efficient, simple to operate and economical to run.  They can be supplied with or without chemical treatment to increase the degree of purification. They use a rectangular flotator tank and the  unique high performance Rendertech Dissolved Air generation System (DAS). Dissolved air flotation is effective on a wide range of purification applications including slaughterhouses, fish, rendering and fishmeal, tanning, dairy, plastic recycling, food, brewery, beverage, pulp and paper, biological sludge thickening.

Rendertech standard DAF designs cover a range of sizes from 5m³/h to 200m³/h.

Filter Belt Presses and Gravity Belt Thickeners

Filter Belt Presses and Gravity Belt Thickeners are proven performers for the dewatering of sludge from a variety of wastewater applications.  Advantages include low capital cost, low maintenance cost and minimum polymer  consumption. The belt press is for applications where the maximum dewatering is required. The Gravity Table provides partial dewatering (thickening). Applications include domestic sewage treatment plants, food processing, textiles, tanneries, pulp and paper, and water treatment.
