APTIDCO- STP Presentation based on SBT andSBR.pptx

This is soil bio technology based treatment for wastewater

1. Presentation On Sewage Treatment Plants Life Link Eco Technologies pvt ltd Bangalore

2. Sewage Is the waste water from a community, containing solid and liquid excreta derived from house holds, street and yard washings Design Parameters

3. Based on biological principles--------------- Anaerobic and Aerobic bacteria. Treatment divided into 3 stages: Primary Secondary Tertiary Solids are separated by screening and Effluent ---------Aerobic oxidation Tertiary ---Disinfection and sedimentation solids handling (1 st stage of purification) (2 nd stage of purification) ( 3 nd stage of purification) Sewage Treatment Plant

4. Primary Treatment Upon arrival via the sewer system, the wastewater is sent through a bar screen, which removes large solid objects such as cover, bottles, sticks and debris. Leaving the screen chamber, the wastewater flow is slowed down entering the grit tank, to allow sand, gravel and other heavy material that was small enough not to be caught by the bar screen to settle to the bottom. All the collected debris from the grit tank and bar screen is disposed of at a sanitary landfill. It allows for the physical separation of solids and greases from the wastewater. The screened wastewater flows into a Raw Sewage tank where it is held for Two hours allowing solid particles to settle to the bottom of the tank and oils and greases to float to the top.

5. Primary Treatment Units

6. Secondary Treatment Biological treatment process that removes dissolved organic material from wastewater. Require continuous supply of oxygen Organic matter + O2 Bacteria, fungi & protozoa CO2, H2O, Ammonia, nitrates & sulphate

7. SEQUENTIAL BATCH REACTOR- SBR

8. SBR Technology

9. SEQUENTIAL BATCH REACTOR- SBR It is batch process. It has fill, aeration, settle and decant steps

Media Media SBT Media Regeneration Media Organics Adsorb on Media Surface Waste Water percolates on media Clean water Drip down out of the media Bacterial Colonies start growing by feeding on adsorbed organics for food, Media Earthworms (White) Feed on the bacterial Colonies CO2 released CO2 released Media is now available for the next cycle adsorption surface is regenerated by bacterial grazing Grazing by earthworms creates new surface free of bacteria, converting the biomass to CO2
