1 Cavitation – Ferment Waste Water Treatment Local Engineering Systems, Ltd, Russia, Tomsk, st. Govorova, 19 «B». Tel. +7 (3822) ,

2 Waste - Water Local Engineering Systems, Ltd

3 Waste – Water Treatment Process Local Engineering Systems, Ltd Waste Water Pure Water Activated Sludge River, Lake, See Warehousing on sludge beds combustion Polygon of waste products Fertilizer

4 The Classical scheme of waste-water treatment Local Engineering Systems, Ltd

5 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) Local Engineering Systems, Ltd

6 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 m 3 /day it is necessary to have 22 hectars, it costs a lot of money Local Engineering Systems, Ltd

7 Main problems of the classical Waste- Water Treatment Plants Activated sludge (dampness %) Sludge beds Again big territory Local Engineering Systems, Ltd

8 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, years Therefore the building of WWTP is not interesting for investors Local Engineering Systems, Ltd

9 Is it possible to change the situation? Our answer is YES!!! Local Engineering Systems, Ltd

10 THE CAVITATION-FERMENT SCHEME OF WASTE-WATER TREATMENT PLANT (WWTP) Local Engineering Systems, Ltd Mechanical purification with sewage regulator Bioreactor (I,II grade) Sedimentator (additional Oxidation) Biofilter (aftertreatment) Ultraviolet irradiation (UVI) Ferment and cavitation stage (dehelmintization)

11 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. Local Engineering Systems, Ltd

12 Cavitator Local Engineering Systems, Ltd

13 Activated Sludge before and after cavitation Local Engineering Systems, Ltd before after

14 As a result of the Cavitation – Ferment Treatment 1. Absence of odour 2. Placement of the WWT Plant directly in the residential area Local Engineering Systems, Ltd

15 3. Placement of the WWTP in one building Local Engineering Systems, Ltd Ulan-Ude, m³/day

16 As a result of the Cavitation – Ferment Treatment 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 Local Engineering Systems, Ltd

17 6. Reducing of the required territory at times. No: - secondary settling basins Local Engineering Systems, Ltd

18 - horizontal aerotanks - air compressor building Local Engineering Systems, Ltd

19 For example, WWT Plant, capacity m³/day Thus, we can return investments only by reduction of the territory Local Engineering Systems, Ltd S=20 hectars S=0,2 hectars Territory in the classical case Territory in the Cavitation-Ferment case

20 As a result of the Cavitation – Ferment Treatment 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 Local Engineering Systems, Ltd

21 Technogenic humus

22 As a result of the Cavitation – Ferment Treatment 9. Reducing of the initial and maintenance expenses 10. Ecological and cheap solution of the activated sludge utilization Local Engineering Systems, Ltd

23 Typical vertical aerotank Local Engineering Systems, Ltd

24 Result of using of the technogenic humus Young growth of the winters wheat Local Engineering Systems, Ltd Without of the anthropogenic humusWith anthropogenic humus

25 Thanks for your attention!
