Local Engineering Systems, Ltd Waste - Water
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
Local Engineering Systems, Ltd The Classical scheme of waste-water treatment
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)
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
Local Engineering Systems, Ltd Main problems of the classical Waste. Water Treatment Plants Activated sludge (dampness 97 -99 %) Sludge beds Again big territory
Local Engineering Systems, Ltd 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
Local Engineering Systems, Ltd Is it possible to change the situation? Our answer is YES!!!
Local Engineering Systems, Ltd THE CAVITATION-FERMENT SCHEME OF WASTE-WATER TREATMENT PLANT (WWTP) Mechanical purification with sewage regulator Biofilter (aftertreatment) Bioreactor (I, II grade) Ultraviolet irradiation (UVI) Ferment and cavitation stage (dehelmintization) Sedimentator (additional Oxidation)
Local Engineering Systems, Ltd 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 Cavitator
Local Engineering Systems, Ltd Activated Sludge before and after cavitation before after
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
Local Engineering Systems, Ltd 3. Placement of the WWTP in one building Ulan-Ude, 200 000 m³/day
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
Local Engineering Systems, Ltd 6. Reducing of the required territory at 20 -100 times. No: - secondary settling basins
Local Engineering Systems, Ltd - horizontal aerotanks - air compressor building
Local Engineering Systems, Ltd Thus, we can return investments only by reduction of the territory For example, WWT Plant, capacity 100 000 m³/day S=20 hectars S=0, 2 hectars Territory in the classical case Territory in the Cavitation-Ferment case
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
Local Engineering Systems, Ltd Technogenic humus
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
Local Engineering Systems, Ltd Typical vertical aerotank
Local Engineering Systems, Ltd Result of using of the technogenic humus Young growth of the winters wheat Without of the anthropogenic humus With anthropogenic humus
