Efficient Plant and Procedure for Sewage Treatment

As part of general environmental protection measures, simple, easy to maintain and efficient water treatment plants are needed also for the waste water derived from isolated buildings and industrial enterprises which evacuate water with great concentrations of oils and fats in the public sewage network. This paper describes a small size plant for house waste water treatment from isolated buildings (vacation houses, fuel distribution stations and their annexes, etc.) or waste water from industrial enterprises having their own low capacity purification stations. Also, it is presented an efficient cavitation air flotation system that isolate fats, oils and solid particles in colloidal suspension from the waste waters of cities and industrial arias and they are adequately processed in order to be separately evacuated. By promoting the proposed solutions, best conditions of hygiene and public health could be assured avoiding water, soil and air pollution in these community areas.
