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 frac water, used to stimulate gas production from shale formations, as well as other types of fluids having various levels of contaminants such as aerobic and anaerobic bacteria and suspended solids. The calcium carbonate scaling tendency is 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.
