Release and Recovery of Phosphates from Sewage Sludge
Some treatment plants in operation have not been designed to fulfill the required standards of phosphorus removal. A possibility to upgrade the efficiency of phosphorus removal could be elimination of the phosphorus returned with sludge processing liquors by releasing and recovering from sewage sludge. The phosphorus recovery can occur from sewage sludge by chemical methods or from supernatant ...
متن کاملMicrobiology of Water and Sewage
549 accuracy of statement is also commendable for so concentrated a treatment. The book is about 30 pages longer than the first edition. Two significant new sections have been added: General Principles of Chemical Carcino-genesis and Some Objections to the Virus Theory. The major additional pages treat new studies on the causes of cancer. Those who are primarily concerned with the metabolism an...
متن کاملDistinguishing metabolic heat from condensation heat during muscle recovery.
When a thermopile is used to measure the heat production of isolated muscle, the muscle is surrounded by gas saturated with water vapour, initially in equilibrium with the muscle. After contraction, the osmolarity of the muscle is raised so that it is no longer in equilibrium with the gas around it, and condensation will occur. When artificial muscles of known osmolarity were placed on a thermo...
متن کاملMercury pollution from irrigation with treated sewage water (TSW).
The lack of potable water in arid countries leads to the use of treated sewage water (TSW) for crop growth. Mercury accumulation (up to 500 ng/g) in agricultural soil originating from daily irrigation with TSW was found at two sites fed separately from a hospital sewage plant and an industrial plant. A control site irrigated with potable water ([Hg] <0.01 ng/ml) had much reduced levels in soil ...
متن کاملLipid extraction for biodiesel production from municipal sewage water sludge
Municipal sewage is a source of various lipids where the lipids can be extracted and converted to biodiesel by transesterification reaction. The present study reveals the properties of extracted Lipids like, Viscosity mmS, Density, kg/m3, Acid value mg KOH/g, Iodine value g I2/100 g, Value of saponification(mg KOH/g), Free fatty acid (%),Capric acid (%),Lauric acid (%),Myristic acids (%),Steari...
