"The purpose of this research study was to investigate methods for the disposal of activated sludge containing metal-precipitated phosphorus. To accomplish this objective, chemically-treated activated sludge or a mixture of the secondary sludge with primary sludge were thickened and dewatered by vacuum filtration and centrifugation. The putrescibility of the dewatered secondary sludge was also evaluated, and since anaerobic digestion is the usual method of sludge treatment, a digestion study was conducted. Secondary sludge for these studies was produced in five 38-gpd (144-1/day) activated sludge pilot plants operated at the Rolla Southeast Treatment Plant. Ferric chloride and alum were added directly to the aeration chambers of four of the plants, while the fifth served as a control; and the effectiveness of Fe++ and Al+++ in removing phosphorus from wastewater was evaluated. The addition of chemical precipitants to the activated sludge aeration chamber had a beneficial effect on the treatability of the sludge from the standpoint of vacuum filtration, but did not significantly alter its thickening and centrifuging characteristics; Al+++ had a greater effect than Fe+++ on all the sludge characteristics studied. The putrefactive characteristics of the dewatered metal-precipitated sludges were similar to those of a control sludge. Very little difference in gas production and composition was experienced during the anaerobic digestion of the chemically-treated sludges and the control sludge. Addition of either Al+++ or Fe+++ to the activated sludge system effectively reduced the concentration of phosphorus released in the effluent; however, greater removals were achieved with Al+++ than with Fe+++ when both were applied at equal M/P ratios"--Abstract, leaf ii.

The dewatering manual integrates bench and pilot scale data generated at the Wastewater Technology Centre with information assembled from the literature, with a view to presenting a practical step-by-step procedure for estimating the size and cost of sludge dewatering installations. Sludge characterization tests are identified, along with a discussion of each test and its potential use for design purposes. A procedure for estimating the quantities of primary, waste activated and digested sludge, including the contribution of sludge from phosphorus removal processes, is presented. Process design procedures for gravity thickening, dissolved air flotation, centrifugation, vacuum filtration and pressure filtration are presented. The procedure for each dewatering method includes a description of the unit process, a discussion of applicable bench or pilot plant tests, a suggested method of scale-up and an example problem. Cost data (December, 1975) for the major pieces of equipment required for each process have been obtained from equipment suppliers and are reported as a function of an appropriate design parameter. Operating and maintenance costs collected from the literature are summarized. A methodology for deve10ping cost estimates is presented and illustrated with example calculations.

Reap the benefits of sludge The processing of wastewater sludge for use or disposal has been a continuing challenge for municipal agencies. Yet, whensludge is properly processed, the resulting nutrient-rich product--biosolids--can be a valuable resource for agriculture and other uses. Wastewater Sludge Processing brings together a wide body of knowledge from the field to examine how to effectively process sludge to reap its benefits, yet protect public health. Presented in a format useful as both a reference for practicing environmental engineers and a textbook for graduatestudents, this book discusses unit operations used for processing sludge and the available methods for final disposition of the processed product. Topics discussed include sludge quantities and characteristics, thickening and dewatering, aerobicand anaerobic digestion, alkaline stabilization, composting, thermal drying and incineration, energy consumption, and the beneficial use of biosolids. COMPREHENSIVE IN ITS COVERAGE, THE TEXT: * Describes new and emerging technologies as well as international methods * Compares different types of sludge processing methods * Explains both municipal and industrial treatment technologies Written by authors with decades of experience in the field, Wastewater Sludge Processing is an invaluable tool for anyone planning, designing, and implementing municipal wastewater sludge management projects.
