Captures rag & grit

S:MAX systems produce screened sludges with the majority of rag and grit removed before they can reach valuable sludge processes, maintaining capacity in tanks further down the treatment line for biomass power generation. Reduced solids passing through pumps, tanks and centrifuges reduces wear and the requirement for unnecessary maintenance.
