The Captivator system from Evoqua improves a conventional process by replacing primary clarification and separate sludge thickening with a VLR system contact tank and a Folded Flow DAF applied to the liquid stream. Organic matter is extracted from raw wastewater and sent directly to anaerobic digestion. Since less BOD is sent to the biological aeration tanks, up to 40% less aeration energy is required by the process. The Captivator system reduces capital investments otherwise required for primary clarification, separate sludge thickening and normal aeration tank volume by up to 20%. It can be applied to both new and existing plants. Click here to learn how the Captivator system can produce 40% more biogas, use 40% less aeration energy and save 20% in capital costs.
