The Classical scheme of waste-water treatment
Local Engineering Systems, Ltd
![Page 5: Cavitation – Ferment Waste Water Treatment Local Engineering Systems, Ltd, Russia, 634057 Tomsk, st. Govorova, 19 «B». E-mail: locsys@sibmail.com Tel.](https://reader036.fdocuments.us/reader036/viewer/2022062314/56649cab5503460f9496c89c/html5/thumbnails/5.jpg)
Main problems of the classical Waste-Water Treatment Plants
Odour nuisance
Placement of the Waste-water Treatment Plant (WWT) far away from residential area
(10-20 km)
Building of incoming collector (sometimes their cost may exceed the cost of very WWT
plant)

Main problems of the classical Waste-Water Treatment Plants
Presence of first and secondary settling basins, using of horizontar aerotanks
Necessity of relatively big territory for WWT plants
For example, for building of WWT Plant with capacity 100 000 m3/day it is necessary to have 22 hectars, it costs a lot of money

Main problems of the classical Waste-Water Treatment Plants
Activated sludge (dampness 97-99 %)
Sludge beds
Again big territory

Main problems of the classical Waste-Water Treatment Plants Heavy electricity consumption and
using of chemical reagents
maintenance of WWTP is expensive
cover of expenditure is very long, 15-20 years
Therefore the building of WWTP is not interesting for investors

Is it possible to change the situation?
Our answer is YES!!!

Bacteria perform the main job in the classical biological purification of waste water. Can we help them somehow to intensity the purification process, for example, with ferments?The ferments are catalysts of biochemical reactions, therefore they can accelerate the decompose process at hundred – thousand times. We use the cavitation process for destroying relatively large microrganismes and thereby to provide an appearance of the ferment groups in the waste water.

As a result of the Cavitation – Ferment Treatment
1. Absence of odour
2. Placement of the WWT Plant directly in the residential area
