Biosurfactants are produced by fermenting pure strains but not treating excess sludge.
For reducing the excess sludge, heat and alkaline treatment was reported as a feasible process.
The full-scale application of ozonation in excess sludge reduction is presented.
The focus was on COD and nitrogen removal as well as excess sludge reduction.
Table 2 shows results of the p NP chemical uncoupling compared with other researchers in minimization of biological excess sludge.
Excess sludge containing 50 mM sucrose was fermented at 50 °C using endogenous bacteria in excess sludge, resulting in a high lactic acid production (8.45 g/L) and in an increased sludge reduction (38.2%).
Meanwhile, the suspended solid index in GCOR and ASR was detected for assessing the excess sludge production.
Utilizing excess sludge from a wastewater treatment plant to produce biodiesel has become an increasingly popular topic.
The conventional activated sludge process is increasingly receiving concerns for its high energy consumption and excess sludge production.
However, the low lipid content in activated sludge has hindered the application of biodiesel production from excess sludge.
Our technique is useful as a facile engineering for reducing excess sludge concomitantly with producing lactic acid by lactate fermentation.
