Pre-reservoirs are small reservoirs having an average theoretical water retention time of a few days. They are situated immediately above the larger main reservoir or lake, whose nutrient loading it is their purpose to reduce. Rare earth sorbents were put into pre-dams to purify pollutants in water. A theoretical deduction showed that low-concentration phosphate adsorption process accorded with a...
Water purification process involves many complex physical and chemical phenomena, and thus it is difficult to realize optimum coagulant dosing control with traditional methods. In this paper, the feasibility of applying a fuzzy logic inference to determine optimum chemical dosage and to control the performance of coagulation process was discussed. Prior to field test, a fuzzy logic based control scheme,...
The method of capillary-waveguide resonance for an investigation of aqueous solutions for detection of the trace content in the wave band (54...78) GHz is used. An influence of a degree of water purification on frequency, Q-factor and absorption depth of energy under resonance is investigated.
Due to the rapid increase of population and the necessity of providing adequate drinkable water supplies, which meet hygiene conditions, modern techniques are applied for water treatment. In particular, this study introduces a flexible model for describing, calculating and estimating the volume of water in distribution tanks through all phases of treatment processes. The model considers a typical...
