KOCHSTAR DOUBLE-PROCESS WATER TREATMENT SYSTEM Russian patent published in 2011 - IPC E03B3/00 C02F9/04 C02F1/50 

FIELD: engines and pumps.

SUBSTANCE: water treatment system includes cleaning systems located between pump stations of the first and the second ascension. Outlet of pump station of the first ascension is connected to inlet of coarse filter in the form of drum screens, which is intended to remove mechanical impurities. From coarse filter the water is supplied to vertical mixer connected to the unit representing chemical plant. Liquid flow from vertical mixer is supplied to clarifier with suspended sludge, and then to high-rate filter. In the section between clarifier and high-rate filter there is water fluoridation plant parallel connected to them. Between clean water tank and high-rate filter there is water disinfection plant parallel connected to them. Clean water tank is connected to pump station of the second ascension. Water intake head consists of perforated cone that performs the function of the first cascade of filter element, located perpendicular to axis of supply pipe and oriented with its apex toward the support ground. On the ground the head is installed by means of three support gussets. Frame of water intake head is made in the form of ribs of rectangular parallelepiped to which perforated cone is fixed in its upper and lower part by means of three braces. Connection of water intake head to supply pipe is performed by means of elliptical junction that performs the functions of the second cascade of filter element and consists of pack of filter screens with the requires carrying capacity.

EFFECT: invention allows improving reliability and increasing efficiency of obtaining clean water from a source.
