It is necessary to reduce the wastewater treatment costs and the amount of sludge caused by industrial fluorine wastewater, for reducing the contaminated water accumulation near to the sea.
In this study, the new coagulant and the microfilter to reduce the calcium oxide were intensively studied. The main aim of this study is to reduce the amount of calcium salt and coagulants used in conjunction, with the reducing cake, to reduce treatment costs. As per the test result, by using improved method A, at pH 10, PAC (17%) 450ppm turns in fluorine removal rates to 93.1 and ACH (12%) 450ppm turns in fluorine removal rates to 91.7% as that of same removal rate with the conventional processing method. ACH is confirmed as the more effective removal fluorine, as ACH consist of small aluminum content less than the PAC.
In method B that have been treating high concentration fluorine wastewater by using calcium oxide unlike method A. Test results of improved treatment method can reduce calcium oxide consumption more than 40%, if applied to the microfilter in the final treated water, which showed a 99% removal efficiency, meeting the effluent standards. Effects on environment ; ① Improvement of water quality in ocean by the effective effluent control ② Improves the working condition with reduction of dust in the air ③ Development of fluorine wastewater treatment system
