The Classical scheme of waste-water treatment


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)



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



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!!!


THE CAVITATION-FERMENTSCHEME OF WASTE-WATER TREATMENT

PLANT (WWTP)


Mechanical purification with sewage regulator

Bioreactor(I,II grade)

Sedimentator (additional Oxidation)

Biofilter(aftertreatment

)

Ultraviolet irradiation (UVI)

Ferment and cavitation stage

(dehelmintization)

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.

Activated Sludge before and after cavitation


before after

As a result of the Cavitation – Ferment Treatment

1. Absence of odour

2. Placement of the WWT Plant directly in the residential area


3. Placement of the WWTP in one building


Ulan-Ude, 200 000 m³/day


4. Absence or reducing of the incoming collector length

5. Reducing of maintenance costs at 3-5 times

- much less electricity consumption- no chemical reagents- reduction of stuff


6. Reducing of the required territory at 20-100 times.

No:

- secondary settling basins


- horizontal aerotanks

- air compressor building


For example, WWT Plant, capacity 100 000 m³/day

Thus, we can return investments only by reduction of the territory


S=20 hectars

S=0,2 hectars

Territory in the classical case Territory in the Cavitation-Ferment case


7. Absence of chemical reagents

8. Obtaining of technogenic humus

We are getting the additional channel for returning of investments, time of returning is reducing up to 5-10 years



Technogenic humus


9. Reducing of the initial and maintenance expenses

10. Ecological and cheap solution of the activated sludge utilization


Typical vertical aerotank


Result of using of the technogenic humus

Young growth of the winters wheat


Without of the anthropogenic humus With anthropogenic humus
