Sludge holding tanks, primary tanks, digester tanks, storm detention tanks, pumping stations and culverts: they are all tanks that play vital roles in wastewater and sludge management. Although these processes are proven to be effective, grit is a major problem when it comes to their efficiency. Grit is an umbrella term for all kinds of inert high-density materials. These materials are highly abrasive at full-flow and cause wear on PD pumps, rotors and decanters. Not only that, but when the grit settles it significantly reduces the capacity in the tanks, meaning their effectiveness becomes significantly impaired.

Usually, when the tanks are cleaned, the material is sent to landfill incurring large costs in disposal and transport for the contractor. However, D:MAX technology allows the waste products to be classified and treated, minimising the costs associated with cleanouts.

In the case of anaerobic digestion, instead of pumping straight to balance tanks, D:MAX can be used before the sludge enters the digester in order to minimise the need for cleanouts or the technology can be employed post-digester to minimise the waste to landfill. This has improved the throughput and system uptime for many operators.

D:MAX is a trailer-mounted system used to process a variety of materials within the water and wastewater industries. The mobile nature of the unit is a key benefit, minimising the transport cost of waste materials.
