Efficient Plants and Procedures for Wastewater Treatment

Ioan Sarbu; Ioan Alexandru Filip
As part of general environmental protection measures, simple, easy-to-maintain and efficient water treatment installations are necessary for the treatment of wastewater from isolated buildings, from transport vehicles (which cannot be connected to a public sewage network) and from industrial enterprises that evacuate great concentrations of oil and fat into the public sewage network. This study describes two plants designed for local wastewater treatment: (1) an autonomous plant, containing self-cleaning filters for wastewater treatment from buildings and transport vehicles (trains, mobile homes, and boats); (2) a small plant for housing wastewater treatment from isolated buildings (vacation houses, fuel distribution stations and their annexes) or wastewater from industrial enterprises with their own low-capacity purification stations. Additionally, we present an efficient cavitation air flotation system which isolates fats, oils and solid particles from the wastewater of cities and industrial areas in a colloidal suspension; this system adequately processes the wastewater from the particles to be evacuated. By promoting the proposed solutions, optimal hygiene and public health conditions can be assured by avoiding water, soil and air pollution in these community areas.
