RCBR is an innovative patented technology with multiple advantages over traditional water purification techniques. The operating principle is similar to that of biological systems with attached biomass, where plastic support elements spontaneously develop a biological film that feeds on the pollutants dissolved in water. Each RCBR module consists of a stainless steel cell containing plastic material that creates a very high active surface in small volumes. The plastic elements provide an optimal habitat for the growth of bacteria by promoting the breakdown of organic matter, nitrogen compounds and surfactants with high efficiencies. RCBR is very versatile and represents an ideal solution both for the treatment of industrial wastewater rich in organic pollutants and for the treatment of civil and domestic wastewater. It is indicated as an effective on-site waste treatment in remote areas and to improve the performance of Imhoff pits or existing activated sludge plants. WHY IT IS CONVENIENT: Simplified management of the system; the oxygenation of the bacterial biofilm is guaranteed by the simple rotation of the cell, without artificial aeration, thus limiting energy consumption. RCBR systems do not require civil works and do not create odors, they can be positioned above ground, placed indoors or insulated as needed and are designed to be transportable. Rotor maintenance consists of simple lubrication of the rotation bearings. EFFICIENCY RCBR has the ability to develop an active bacterial surface up to seven times higher than other biological contactors. DIMENSIONS A RCBR reactor, to treat up to 100 mc / d of civil waste, occupies a space of less than 15 m2. APPLICATIONS RCBR is a secondary water purification treatment according to European legislation (2000/60 / EC); It can be easily integrated into existing systems.
