Filtration installation

RU patent № 2243022

The invention relates to the installations for liquids filtration and can be used for purification of the natural and sewage water, concentration of the solutions in chemical, food and other branches of the industry. The filtration installation contains a filter, hydraulic accumulator, pipelines of the initial, purified and non-purified liquid with cocks, pump, by-pass regulating cock, electric valve mounted on the pipeline of non-purified liquid. The installation is equipped with the pressure transducers mounted on the pipelines of purified and non-purified liquid with the possibility to transfer the signal to electric valve. The valve keeping the initial liquid flow rate at the same level as in filtration while washing is mounted on the pipeline of the initial water. The technical result is an efficiency increase in using the installation owing to increase of the purified liquid output, increase of the installation filter life at the expense of pressure difference rise on the filter while washing.
