Due to the deterioration of the state of reservoirs, the need for water treatment equipment has increased. Requirements for it depend on the necessary chemical composition of water. The most commonly used filters for cleaning. As a rule, there are three main methods: mechanical, sorption and ion -fund.
For the first time, wastewater was cleaned at the end of the 19th century in England. True, it was significantly different from modern. First turned to the soil method. Specialists watered field drains, and then filtered through the soil layer. The same country became a pioneer on the first device of biological cleaning. This method today is the main thing for the cleansing of city efforts. Warm treatment is carried out taking into account modern technologies.
But in addition to this system, the wastewater will have to go through several more steps of mechanical cleaning. Initially, water carries a lot of garbage with it. It is filled out immediately thanks to a large grate. Thus, the rest of the equipment is protected from wear. The collected garbage goes to the landfill. Then the water enters the next lattice, where the grid is 5 mm.
Despite several stages of cleaning, the result still leaves much to be desired. That is why additional equipment is used in residential buildings and in summer cottages. There are several requirements that must be considered when installing water treatment facilities. First, find out the chemical composition of the liquid. Secondly, the pressure of the water supply system. Thirdly, 2 kW of power and 220 volt voltage are required.
It is necessary to place a drainage device 1.5-2 kV. m. To carry out reverse filters, we need a sewage system. One -time discharge is at least 400 liters. Not every local treatment plant can withstand this. But there is another option – independent discharge. It is even preferable. There is no negative impact on the environment.
Water treatment equipment is selected taking into account the composition of the liquid. The choice is influenced by excess and lack of certain substances. Therefore, it is advisable to conduct the most complete analysis. The tasks that lie on the cleaning system – removal of garbage and gases, softening, ultra – and microfiltration. But most filters are able to cope with additional load. For example, get rid of iron.
After installation, the device will need in periodic service. Experts check the quality of work, find out the condition of the filter control units, rinse the mechanical parts, adjust the settings. Also, if necessary, chemical reagents can be replaced.
