Wastewater Sludge Processor

GrahamTek's Sludge Processor technology was developed to produce a material of a fine micron size. Material used is generally of no economic benefit in their current state, but becomes commercially viable once broken down to a fine powder. Commonly used materials include low grade coal, soft rock minerals and sludge from wastewater treatment works.

The Sludge Processor is extremely effective when processing wastewater sludge. Sewage sludge ("bio solids") is created at wastewater treatment plants as sewage water is processed and purified. Currently many municipalities are facing challenges to dispose of these solids in an environmentally responsible and economically viable way. The Sludge Processor can de-water bio solids to reduce their volume and thus reduce the associated transportation and disposal costs. 

The Sludge Processor is certified to meet the US Environmental Protection Agency rules for the destruction of pathogens including salmonella, e-coli, and fecal coli forms. The dry powders produced by the system are suitable as fertiliser in the agricultural industry, or for use as a fuel source where they can replace fossil fuels.

The integration of the Sludge Processor into the Water Treatment system helps our clients Reduce, Reuse and Recycle while at the same time giving our clients a vital competitive advantage.
