GROUNDWATER TREATMENT PLANT Russian patent published in 2018 - IPC C02F9/08 C02F1/74 B01D24/14 E03B3/06 

FIELD: chemistry.

SUBSTANCE: groundwater treatment plant comprises a vertical cylindrical body 1 divided by a horizontal grid 2 into an aeration zone 3 located at the top and a filtration zone 4 at the bottom of the body 1. The body 1 is also provided with a cylindrical mixing chamber 5 disposed coaxially with the body 1. The aeration zone 3 is connected to the pipeline 12 to supply water for flushing and to the pipeline 6 to supply source water for cleaning, which is connected to the pipeline 8 to supply a water-air mixture through the ejector 7, at the end of which there is a nozzle 9. The aeration zone 3 is provided with a gas outlet 10 comprising a relief valve and a gas exhaust pipe 11 configured to vary its length within the aeration zone 3. The filtration zone 4 contains a floating load 13 with a grain size of 3-5 mm and a collection system 14 connected to the drainage pipelines of the purified water 15 and flushing water 16.

EFFECT: invention allows to increase the degree of water purification from iron and suspended solids while reducing the cleaning time.
