TECHNOLOGY AND EQUIPMENT OF THE STATION STABILIZING THE TREATMENT OF AGGRESSIVE UNDERGROUND WATERS

Authors

Abstract

Monitoring researches  cauuied out on the quality of underground waters in 83 localities of eight regions in Ukraine showed that in  63   cases they were characterized by different degree of aggressiveness in relation to metal and concrete. Acting stations of deferrization are not designed for conducting the stabilization treatment of water which in being transported to consumers is undergoing the recurrent pollution by corrosion products. The aim of the paper is the development of the technology and equipment for the stabilization treatment of aggressive underground waters at the working water intake with the capacity of 8000 m3/day and night. By parameters of the quality  underground waters belong to neutral ones (pH 7,05 - 7,15), with increased bicarbonate alkalinity (7,0 - 7,3) and compounds of ferrum (0,15 - 1,0 mg/dm3), with a calculated stability index IL - 0,20 ... - 0,35. The basis of suggested technology  was the principle of subsequent formation of the protective carbonate film on inner surfaces of pressure pipelines by way of introducing the clarified solution of alkaline reagent - lime milk. The technological scheme  included solution tanks, clarifiers - regulators, capacities for collecting worked-out lime solution, three groups of pumps, additional equipment. As a result of researches carried out  optimal concentrations were determined of alkaline reagent both for growing the protective carbonate film on the inner surface of pressure waterlines (37 - 40 mg/dm3) and for keeping the parameters of water quality in a stable state (20 - 23 mg/dm3). The optimal content was determined of cations Ca2+ (800 - 1200 mg/dm3), values of pH (10 - 11) and the optimal quantity of recycles of operating solution in clarifiers-regulators (n=6), and also the interrelationship of  water consumptions  on PC II to operating solution Ca(OH)2 which are within the boundaries of 30 - 33 m3/hour of water per 1 m3/hour of clarified solution.
