  1. Local Engineering Systems, Ltd, Russia, 634057Tomsk, st. Govorova, 19 «B».E-mail: locsys@sibmail.comTel. +7 (3822) 251650, +7 913 829 3007 Cavitation – Ferment Waste Water Treatment

  2. Local Engineering Systems, Ltd Waste - Water

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

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

  5. Local Engineering Systems, Ltd 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)

  6. Local Engineering Systems, Ltd 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

  7. Local Engineering Systems, Ltd Main problems of the classical Waste-Water Treatment Plants Activated sludge (dampness 97-99 %) Sludge beds Again big territory

  8. Local Engineering Systems, Ltd Main problems of the classical Waste-Water Treatment Plants Heavyelectricity 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

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

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

  11. Bacteria perform the main job in the classical biological purification of waste water. Can we help them somehowto 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. Local Engineering Systems, Ltd Cavitator

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

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

  15. Local Engineering Systems, Ltd 3. Placement of the WWTP in one building Ulan-Ude, 200 000 m³/day

  16. Local Engineering Systems, Ltd 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

  17. Local Engineering Systems, Ltd 6.Reducing of the required territory at 20-100 times. No: - secondary settling basins

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

  19. Local Engineering Systems, Ltd 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

  20. Local Engineering Systems, Ltd 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

  21. Local Engineering Systems, Ltd Technogenic humus

  22. Local Engineering Systems, Ltd 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

  23. Local Engineering Systems, Ltd Typical vertical aerotank

  24. Local Engineering Systems, Ltd Result of using of the technogenic humus

  25. Thanks for your attention!
