dc.description.abstract | Objectives: In order to review both the effects of sewage sludge dewaterability and deodorizing ability in theexisting advanced sewage treatment process, BIO-CLOD (a solidified mixture of 10% Bacillus concentrate andinorganics) was used as an inorganic conditioner effective for deodorization treatment in addition to the removalof organic matter and nutritive salts. Methods: Sludge dewaterability was evaluated using specific resistance to filtration (SRF) experiments with sixagitators and two types of commercially available BIO-CLOD; one that is made by grinding solid matter(powdered BIO-CLOD) and one that has been obtained by sieving a separation with a particle diameter of 100mesh (100 mesh BIO-CLOD). For deodorization odor treatment experiments, 20 g of commercially availablesolid BIO-CLOD was submerged in four liters of sewage sludge and mixed and agitated for 45 days. Results: When BIO-CLOD was injected into sewage sludge to experimentally compare specific resistance tofiltration (SRF), the optimum amount of BIO-CLOD to be injected was shown to be 2% w/v and the SRF valuein this case was 1.35x 1012m/kg. pH changes following BIO-CLOD injection were within 6.5-7.0. By 14 daysafter submerging BIO-CLOD into the sewage sludge to evaluate its deodorizing ability, H2S decreased by 68%and methyl mercaptan decreased by 74%. By 45 days after the submergal, both items decreased by 100%,indicating deodorizing ability. Conclusion: To compare the levels of dewaterablity of sewage sludge at different particle sizes of inorganicconditioner, powdered BIO-CLOD, particle size 100 mesh BIO-CLOD, and bentonite were tested. It could beseen that as the powdered BIO-CLOD increased, the precipitability increased up to 62% in 30 minutes. As aninorganic conditioner, BIO-CLOD was identified as a stable sludge conditioner that does not affect pH. | - |
