Radovenchyk I. Use materials with capillary properties in sludge dewatering and water treatment processes.

A scientific basis for the creation in industrial enterprises effective, simple and energy-saving technologies of liquid and solid phases separation and separation of immiscible liquids were developed. The main regularity of fluids movement in materials with capillary properties was formulated, the fluid flow in the capillaries was calculated and obtained dependences were confirmed experimentally. The influence of various factors on the intensity of fluids movement was analyzed, the basic conditions for most cost-effective liquids transportation was defined. The influence of type of material with capillary properties and properties of liquids that are transported by the capillaries, on the efficiency of the capillary filters were analyzed. The applying of materials with capillary properties for separating liquid and solid phases was proposed. The effectiveness of this processes was studied, the relations between basic parameters of this process for paper sludge suspensions, activated sludge, iron ferrocyanides, calcium carbonate and magnesium hydroxide were discovered. It was found that even without pH adjustment and flocculants treatment method provides better results of liquid and solid phases separation than traditional filtering. The high efficiency of applying the materials with capillary properties for the separation of the immiscible liquids components was confirmed. The devices constructions for realization of proposed processes were developed.
