Investigation of the Excess Sludge Reduction in SBR by Oxidizing Some Sludge by Ozone
The excessive biological sludge production is one of the disadvantages of aerobic process such as SBR. So the problem of excess sludge production along with its treatment , and disposal in aerobic processes in municipal and industrial waste water can be seen in many parts of the world even in our country . to solve the problem of excess sludge production , reducing in by oxidizing some of t...
متن کاملReduction of excess sludge production by ozonation
The literature on reduction of excess sludge production by ozonation is summarized. Two sequencing batch reactor experiments where sludge is ozonated for this purpose are performed. The purpose of these is to evaluate the prospects of using ozonation to reduce excess sludge production in two different kinds of sludge. Urban sewage sludge is used in the first, and paper mill sludge in the second...
متن کاملexcess sludge minimization in conventional activated sludge pilot plant by three chemical matters
the excess sludge treatment and sludge disposal are major factors to the over-all economy of wastewater treatment plants (wwtp). the ideal solution to the problem of sludge disposal is to combine sludge minimization with contamination removal at the source. in this study, the effect of ozonation, chlorination and 3,3,4,5–tetrachlorosalicylanilide (tcs) to treat part of the return activated slud...

متن کاملNew approaches to minimize excess sludge in activated sludge systems.
This paper presents three new approaches to reduce excess sludge production in activated sludge systems: 1) modification of conventional activated sludge process with insertion of a sludge holding tank in the sludge return line; 2) chlorination of excess sludge so as to minimize excess sludge production; and 3) utilization of a metabolic uncoupler, 3, 3', 4', 5-Tetrachlorosalicylanilide (TCS) t...
