Slurry could be recirculated and enriched. They are economic when highly wettable dust with higher density than water, if grain size is more than 2-3 micron, with good efficiency (99%) and with 1.000-3.000 Pa pressure decrease. Increasing the equipment's pressure decrease to 3.500 Pa, they are suitable to collect dust with 1-2 micron grain size.

Some fields of application: mining, stone-, ore- and coal processing, metallurgy, iron- and steel-casting, dressing-off, processing of foundry sand and fire-proof materials, alumina production, aluminium metallurgy, chemical industry,fine powders in mechanical surface finishing, sand-blasting, tanning, galvanization, to collect acid- and alkali fumes, as well as in construction and building-material industry during processing sand, ceramic and fire-proof materials.

The equipment is suitable for purification of normal air and hot flue gases. They are applicable up to 353 K temperature in normal design, and up to 623 K temperature in special design. Value of pressure decrease could be adjusted between 1.000-3.000 Pa, subject to collecting requirements. Quantity of recirculated washing liquid is 0,25-1,0 kg/ m3, at 293 K.
