Abstract: The present invention provides a system for treating wastewater in which the majority of solids and biological oxygen demand compounds are separated from the wastewater feed using a primary separation process, to produce a solids phase and a water phase. The solids phase is irradiated to reduce the level of pathogens such that it is safe to use as a soil substitute and/or additive so that the solids can thus be disposed of in an environmentally-friendly manner. In additional embodiments, the solids that have been disinfected by radiation are mixed with a suitable inert filler material to produce a soil substitute, fertilizer, compost, or other soil additive. The liquid phase is treated in a substantially smaller system than would be required for treating the full-strength wastewater that can include a suspended media biological regeneration reactor system.

Abstract: A system for producing and supplying a coolant to a filtration sub-system, and for reconditioning and recombining a return flow of used coolant. A main reservoir is in two way communication with the filtration sub-system via a clean coolant outlet and a dirty coolant return. An inlet feeds an untreated water supply to a de-ionization canister. A mixing valve in communication with the inlet recombines a remaining untreated portion of the water supply with the de-ionized portion. A mixing pump intermixes the water supply with a chemical concentrate to produce a coolant delivered to a main reservoir. A volume of coolant is drawn through an outlet from the reservoir and communicates the coolant to a particle filter, a chiller, and prior to outputting to the filtration sub-systems. The used return coolant is filtered and reintroduced to the main reservoir.

The apparatus may take the form of a filter, a conveyor belt or an impeller to be used in a processor to collect mineral particles in the slurry, or in a tailings pond to collect mineral particles in the tailings. The filter, conveyor belt or impeller has a collection area made of or coated with a synthetic material having a functional group, either anionic or cationic to attach to the mineral particles. Alternatively, the synthetic material has hydrophobic molecules to render the collection area hydrophobic. When the mineral particles in the slurry or tailings are combined with collector molecules, the mineral particles also become hydrophobic. The hydrophobic mineral particles are attracted to the hydrophobic collection area. The filter, conveyor belt and impeller may have a plurality of passage ways in order to increase the contacting surfaces.
