The Hydroxyl system uses ozone to disinfect the effluent rather than chlorine, thereby eliminating the need for chemical storage on the vessel. In biological treatment systems, bacteria are used to "eat" the organic products and chlorine is subsequently added to disinfect the effluent prior to discharge. Non-biological systems screen the solids but the harmful byproducts of using chlorine are still evident and the soluble organics are not removed. As a result, this type of system…
