Página iii - Four activated sludge processes (conventional, step aeration, contact stabilization, and Kraus) were studied in parallel using 1-gpm pilot plants. At the end of the 12 months, the conventional and step aeration processes were eliminated from further consideration. The contact stabilization and Kraus processes were studied for an additional four and one-half months. Contact stabilization was selected as the most promising process and units were operated for an additional five months to obtain refined...
Página iii - Shortly after initial start up, the pilot plants became infested with filamentous organisms identified as a bacterial species of the genus Thiothrix, a sulfur storing organism. Of various procedures implemented, chlorination of the return activated sludge successfully controlled the growth of filamentous organisms which caused sludge bulking. It was also necessary to add nutrients to achieve the desired BOD:N:P ratios. The operation of the pilot plant units during the last study phase gave the following...
