Environment Water and WastewaterReverse Osmosis
Versatility cleaning. Reverse osmosis purified water from the majority of the impurities and the output gives little distilled water. Quality stability of purified water quality of water at the outlet has a constant high level, regardless of the lifetime of the diaphragm to 3, since the water purification installation module is present to wash the membranes with reagents that remove deposits from the surface. Ease of use The high level of automation and a comprehensive installation of protection eliminates the need for constant monitoring of its work and does not require for its service operator with special knowledge and skills. Environmental safety in the work setting does not use or produce environmentally hazardous substances. Compactness Even plants with high productivity have relatively small dimensions, for example, setting output 110 thousand. Liters per hour having a width of 6 meters, a height of 2 meters and a depth of 4.5 meters. Any level of automation depending on customer requirements, it is possible to provide any level of automation installations. Low operating costs cost of membrane water purification plant using a reverse osmosis method is slightly higher than installation using an alternative method, for example, chemical desalting. However, the operating cost of reverse osmosis units are considerably lower. In industrial and semi-industrial companies lower operating costs in the short term offset the costs incurred at the stage of the purchase of equipment. This is due to the fact that in this case there is no need for construction and maintenance of special facilities for the storage of chemical reagents is no need in the construction of sewage treatment plants, reduced harmful impact on the environment.
The process of reverse osmosis purification occurs by passing water under high pressure through a semi-permeable membrane which retains most of the impurities. In this case the raw water is divided into two flows: a permeate - desalinated water and the concentrate was - concentrated solution of salts and impurities. The proportion of the initial permeate is 60 to 80%. This number depends on the composition of the source water and the technical features of filtering unit: performance, the type of membrane and other factors. Reverse osmosis is capable of almost complete sterilization of the water, purifying it from the high molecular weight contaminants, salts, chemical and biological contaminants, bacteria and viruses.
