The management of biosolids presents both challenges and opportunities for efficiency and sustainability. Technologies like electro-osmosis dehydrators, thin film dryers and advanced thickeners are at the forefront of innovation, offering solutions that significantly reduce sludge volume and disposal costs. Check out some product options below.
ELODE USA Electro-Osmosis Dehydrator
The compact Electro-Osmosis Dehydrator from ELODE USA can easily retrofit in line with many existing presses. It is specified to reduce sludge disposal cost by 60% by producing much drier sludge cake. It uses the electrical potential difference in the sludge cake to separate water in the process and it works on 95% of municipal cakes tested without any chemical, polymer, heat nor mechanical press. It can be used to turn 15 to 20% DS cake to 40 to 45% DS quickly.

Nederman MikroPul Thin Film Dryer
The Thin Film Dryer from Nederman MikroPul is a versatile sludge dryer that can process all types of sludge, including digested, undigested and industrial sludge, as low as 10% DS. It achieves a variable sludge dryness range of 30 to 95% DS, and the dryer has been successfully utilized for various applications such as Class A, landfilling, composting, alkaline stabilization, incineration, gasification, pyrolysis and solid fuel production. With a simple design, the dryer has a single-drive motor, requires no separate feed system and generates less than 200 cfm of exhaust vapor, which can be easily treated. Its high-efficiency design consumes 1,150 to 1,300 Btu/lb of evaporated water and can recover up to 85% of this heat for other purposes, including digester and building heating.
