Sewage Treatment Plant

Treatment Scheme

In the treatment system sewage water enters through Bar screens where floating matters are removed. The sewage water is then pumped to extended aeration system where the organic matters is aerobically oxidised. The effluent is then taken to a settling tank where bio-mass is seperated out in the form of settled sludge and is returned back to the system. The excess sludge from the settling tank is taken to the sludge drying beds for drying and disposal. The treated effluent is collected in sump after the addition of bleaching powder solution through a doser and then treated sewage is pumped to overhead tank for horticulatural purposes.

    Can lime be added in aeration tank of sewage treatment plant ?
    Does carbonates from lime effect STP operaation ?
    Can defoamer be used in STP aeration tank ? How does addition of FAB media in sewage aeration tank increase the capacity ?
