I would like to know your suggestions about the compound we can use for the start-up of an activated sludge plant which serve a winery. The winery will begin to discharge its wastewater at the end of august, we need to start-up the plant in order to have a biomass partially ready to work at this time. What i would like to know is some economic compounds, easilly finding in the market, with a balancing composition in COD-N-P. Thank you in advance.
Using activated sludge samples(10 liters) from an existing facility,either a sewage plant or preferably another winery's sewage plant, would provide the microbiological flora to start up a new facility. After that seeding, you will need to determine pH carefully and adjust with buffers.
Innoculum in the form ob diluted biosolids and sludge from an existing winery effluent plant is to be fed into the reactor. A continuous recycling of the sludge is to be carried out for atleast the minimum retention time derived to ensure maximal adaptability of the microbes to your effluent.
The biosolids re-circulation can be carried out for another few weeks to ensure maximal COD conversion.
There are also some commercially available Effective Microorganism Solutions which can rapidly increase the microbial population
In practical experience using activated carbon by either granular or powdered allows increased biomass growth, I used leftovers from some industrial processes enabled browser coal. Which helps the process is that the charcoal adsorbs mainly from the same bacteria toxins process.
I recommend to inoculum a diluted solution by some out of dated baby milk powder to the system to encourage the biomass growth. Although seeding of activated biosolid from a same existing wastewater treatment plant ,or every municipal sewage plant, would provide the biomass flora to start up a new facility.
regards
