DEVICE FOR UNDERGROUND WATER DEIRONING Russian patent published in 2009 - IPC C02F1/64 

FIELD: water supply.

SUBSTANCE: invention concerns underground water deironing and can be applied in domestic systems. Device for sewage treatment includes coarse filter, ejector for water saturation with air oxygen, generator for iron hydroxide development, vessel assembly, filters with cylindrical porous elements of spatial globular structure, oil-free compressor. Vessel assembly is made in the form of two coaxial drums connected in lower part by tilted nozzle pipes to sections of vortex chambers formed by radial partitions, horizontal bottom sections and side surfaces of drums, and by highly porous metal caps mounted askew with gap over internal drum to maintain swirling of flow with load and developed sediments. Highly porous perforated metal shelves are mounted inside internal drum space on resilient supports, with pore size increasing in flow direction and loaded with quartz sand traveling freely in the pore space. Sand washing out is prevented by limiting mesh along external shelf surfaces, with mesh cell diametre smaller than characteristic size of load particles activated by iron hydroxide developed in coaxial gap space of generator filled with load by 1/4.

EFFECT: enhanced efficiency of underground water deironing.
