Raw Sewage

 

Raw Sewage

Water, sludge, and metal


Powell Electrocoagulation has proven effective in treating sewage water, sewage sludge concentrations, and sewage sludge metal fixation sufficiently to enable land application.

After electrocoagulation, treated domestic sewage water will, in most cases,”……be better than the raw water from which it had originated.” 7
