The role of bound water content in defining sludge dewatering characteristics
Several available methods of measuring sludge bound water content in the laboratory were examined. The effect of polymer conditioning on the bound water content of biological sludge samples was measured using the dilatometric method. The effects of mechanical dewatering on the bound water content …

Effect of Digestion Processes on Dewatering and Bound Water Content of Sludge
… portion of the operational costs of a wastewater treatment plant, contributing up to 50% of the total expenses in certain instances. Sludge dewatering and drying therefore become necessary not only from the operational perspective, but also from the economical viewpoint. The J-Vap process …

Impact of polymer type, dosage, and mixing regime and sludge type on sludge floc properties
… mixing rate, and solution ionic strength on bound water content of sludge flocs. Data determined to evaluate the extent of dewatering included: percent dry solids, bulk density, bound water content (determined by dilatometric method), floc density (determined by isopycnic centrifugation), and …

Coagulation study of a bound water bulked sludge
… added to a sludge which has bulked due to a high bound water content. The effect of coagulant addition upon microbial metabolism was studied using dissolved oxygen uptake. Coagulant dosages ranging from 200 mg/l to 700 mg/l were added to 1000 mg/1 and 2000 mg/l mixed liquor volatile suspended …

Thermoneutral Housing Did Not Impact the Combined Effects of External Loading and Raloxifene on Bone Morphology and Mechanical Properties in Growing Female Mice
… by binding to collagen and increasing the bound water content in the bone matrix in a cell-independent manner. In this thesis, active tissue formation was induced by non-invasive external tibial loading in female mice and combined with raloxifene treatment to assess their combined effect on …

Dynamic modelling and optimal control of the primary and secondary drying stages of freeze drying of solutions in trays and vials
… a tray freeze dryer to obtain a desired final bound water content in minimum time is formulated as an optimal control problem with the use of the rigorous unsteady state mathematical models for freeze drying in trays and vials which were developed in this work. The heat input to the material …
