Phosphorus Recovery using the 'Rephosmaster(TM)' Crystallization Processes for Wastewater Treatment Plants

Phosphorus Recovery using the 'Rephosmaster(TM)' Crystallization Processes for Wastewater Treatment Plants

Two novel phosphorus recovery processes, which effectively enable the reuse of recovered phosphorus as a resource, have been developed. These processes have been designed with full consideration given on the specific characteristics (sewage components, chemical concentrations, flow rates, etc.) of wastewater or sludge generated from sewage treatmen ...

Wastewater Treatment Process

Wastewater Treatment Process

A wastewater treatment process for treating wastewater comprising a water-based dispersion containing a surfactant, a colorant and silica, as well as other solid matter, wherein the wastewater is treated using a polysilicato-iron coagulant.

CLEANING APPARATUS AND CLEANING METHOD

CLEANING APPARATUS AND CLEANING METHOD

This is the clearing technology that an object, such as parts or components, having oil substances thereon is cleaned efficiently with water. This technology can effectively prevent the removed oil substances from re-sticking to the surface of the object, after the oil substances is once removed from the surface of the object. This effective preven ...

Particle filter for e.g. diesel engine, has filter pocket surfaces manufactured from sintered material that contains carrier material and sinterable material, where carrier material is sheet material with openings in comb-lattice form

Particle filter for e.g. diesel engine, has filter pocket surfaces manufactured from sintered material that contains carrier material and sinterable material, where carrier material is sheet material with openings in comb-lattice form

The filter has filter pocket surfaces that are manufactured from a sintered material (36). The sintered material contains a carrier material (38) and sinterable material. The carrier material is a sheet material, and includes openings (42) in a comb-lattice form. The openings are pressed in the form of catena (54) into the carrier material. The ope ...
