In 2009, arla foods in Videbaek, denmark, realized that their current methods of sludge dewatering were unsustainable. a sound financial and strategic decision was made by arla foods to invest in a better dewatering solution to handle the large volume of wastewater coming from the company’s milk and cheese production.

Membrane filter presses at LOWER FOX RIVER, USA

Environmental remediation is always an ambitious task. And the case of the Lower Fox River remediation project in Wisconsin is no exception. To reduce risk to both human health and the environment, the project aims to remediate PCB-impacted sediments from a 21.4-km stretch of river through dredging, capping, sand separation, sediment dewatering, water treatment, and disposal.

CENSOR decanter upgrade at multiple sites

Recyclers of post-consumer and postindustrial plastic materials rely heavily on decanter centrifuges. But the processing of shredded plastics into several fractions is not always a simple task. Excessive or varying feed rates can lead to regular blockages. And a blocked feeding system must then be stopped, flushed, and cleaned. All of which leads to significant production losses and additional manpower requirements.
