Waste treatment process for coal gasification fly ash
First Claim
1. A process for treating coal industry wastewater comprising the steps of:
- fluidly connecting to a source of industrial wastewater fluid flow and pressurizing the fluid flow;
injecting ozone into the pressurized fluid flow;
directing said fluid through a flash reactor having flow paths that create areas of severe velocity and pressure changes for reducing the ozone into nano sized bubbles;
passing said fluid through a hydrodynamic mixing manifold constructed and arranged to cause hydrodynamic cavitation of said fluid;
directing an output of said hydrodynamic mixed fluid through a converging dynamic nozzle;
conveying said fluid into a reactor having a plurality of ultrasonic transducers;
energizing a plurality of ultrasonic transducers positioned within said reactor to generate acoustic cavitation within said fluid; and
changing the electrical potential within said fluid upon energizing a plurality of anodes and cathodes positioned within said reactor;
whereby the process reduces the scaling potential of said fluid, destroys bacteria within said fluid and heavy metals within said fluid precipitated.

Abstract
Disclosed is an improved water treatment process that operates on a continuous flow of fluids that are subjected to hydrodynamic waves, acoustic ultrasonic waves in combination with injected ozone and electro chemical treatment. The treatment system provides a cost efficient and environmentally friendly process and apparatus for cleaning and recycling fluids as contaminated as coal slurry, as well as other types of fluids having various levels of contaminants such as aerobic and anaerobic bacteria and suspended solids. The volatile organic compounds are reduced to an acceptable level without the use of acids, ion exchange materials, or anti scaling chemicals which is of economical and environmental significance and benefit.
