Designing horizontal clarifiers and studying the efficiency of the water liming process

Summary

Chemical softening methods have been widely used in water treatment. As shown in the previous review, the chemistry of the process has remained unchanged for the past 100 years; however, the instrumentation has changed. This provides for increasing significantly the capacity of the devices and their efficiency. Mediana-Filter R&P JSC carried out research on the development of domestic intensified devices. The studies were carried out in a small-scale laboratory three-chambered horizontal clarifier with a lamellar settling tank and in a pilot clarifier with a variable chamber volume. The optimal procedure of introducing chemicals, the minimum and optimal residence time of water in the clarifier chambers have been determined. The achieved rate of the upward flow in the zone of clarification in the boundary conditions was 25 m/h. The data obtained was taken as a basis ground for designing industrial apparatuses.
