AERATION TANK DESIGN FOR STP

[Dibya Ranjan Dash]

How can we design aeration tank & aeration system for STP where Min Temperature is 3 deg C.

Plz. contact me through [e-mail] 

I can suggest a way out to do away with mechanical aeration.

[Dibya Ranjan Dash]

Thank you very much sir for your reply. But my question is will microbes be able t0 degrade BOD  at 3 deg c.

Can you please provide the Details like

FLOW/day

COD.

Is any primary treatment is there.

We provide special microbes which works in cold conditions.

MSI Biotech has developed Effective Biotechnological Tools for reduction of the organic loads present in Waste water (i.e. Effluents) Micronutrient & Bio-cultures for the growth and potentiality of biomass for the waste management, and specialized Biocultures for Biogas Production, for Nitrogen and Phosphorus, Biozyme OD an odour removal product, and Bio-coagulants for the colour removal and foam reduction in sewages in the drains and nullahs. And the products has been developed these products after a prolonged R & D, testing and field trials.

MSI Biotech  provides customized economic solutions for various sectors like leather Tanning, Sugar mills, Pharmaceuticals, Beverages, Domestic Waste, Fertilizers industries, Paper Mills, Textiles, Dyes, Dyeing, etc.

We do undertake Assignments in stabilizing the treatment process in the Effluent and Seewage Treatment Plants, and we do undertake research assignments projects also.

Dear Sir,

Flow rate is 800KLD.

conventional Primary system will be provided with aeration system.

Hi Dibya,

Sorry for a very very late reply, but the key for successful operation of your aeration tank would be HRT, aeration and the microbes in your aeration tank.

If you need any help please feel free to email me at [e-mail] .

very tricky situation.

Is the question is aeration or temperature?

Because, any aeration may not rise the temperature and may not facilitate the growth of biofilm.

rather to worry more about aeration its better to worry about design for optimizing the temperature, and  then to optimize the aeration.

If the BOD is high, we may go for anaerobic systems, where we can increase the temperature as heat is generated during digestion. The biogas generated may be used to heat the aeration tank water to optimize the temperature.

If the BOD is moderate then go for UASB.

If the BOD is low, perhaps u may think of using solar panels (thermals/PVs) to warm the aeration tank water.

Just shared my opinion.

Tks for giving me a research topic. Will work in my lab and let u know the results. But takes time.

If u get to know the answer, pls share with us.

regards

I think you are talking about the atmospheric temerature. Check the general water temperature in that area. It must be higher than the atmospheric temperature. Also the aeration activity in the aeration tank will not allow it to drop below some limit. I can't be able to give you the exact figure, but it must be much higher than your 3 degree centigrade.
