Retrofit or retrofitting consists of adapting a plant’s capacity to new operating and / or design conditions in scenarios where the current plant increasingly demands efficiency with lower costs. Often the application of this procedure in a water, effluent or […]
The acronym “POA’s” stands for “Advanced Oxidative Processes”. POA’s are systems based on the reaction between potent oxidants or between oxidants and metal catalysts, in some under the action of irradiation, which are dissociated to generate hydroxyl free radicals (● […]
Stabilization ponds are biological treatment systems in which the stabilization of organic matter is carried out by bacteriological oxidation (aerobic oxidation or anaerobic fermentation) and / or photosynthetic reduction of algae. In general, ponds have excellent treatment efficiencies. In terms […]
The given name, “Biological Filter”, does not portray the mechanism of the process. In fact, the denomination is incorrectly employed because no sieving or filtration operation is carried out. Briefly, the contact of the influent sewer with the biological mass […]
Thermal drying of sludge has been presented as an excellent alternative for the reduction of sludge moisture in TEEs and ETAs. It is a process of reducing humidity through the evaporation of water to the atmosphere with the application of […]
MBR (Membrane Bio Reactor) technology is considered to be the most advanced in the treatment of domestic and industrial effluents. Its application encompasses several situations with a high efficiency of removal of solids and organic matter. HOW IT WORKS? The […]
Unlike sludge from wastewater treatment plants (ETEs), sludge from ETAs has larger applications on a daily basis. This is due to its composition, since the sludge of an ETA hardly presents toxic substances (heavy metals) that harm the environment. Due […]
Septic tanks are alternatives in areas (urban and rural) where there is no sanitary sewage service, requiring the implementation of some means of final disposal of treated sewage in order to avoid contamination of soil and water. In general, the […]
The Wetland system has been presented as an alternative to the biological treatment of sewage. It is a process that uses physical, chemical and biological filtration in the transformation / purification of pollutants present in the sanitary or industrial sewage, […]
Most of the water and effluent treatment systems currently in place in Brazil require studies of process engineering and the correct selection of quality equipment and materials. These are the basic conditions that assure customers that their plants operate at […]
