The sulfuric recovery from wastewater by ion exchange is another way for selected to solving the problems of chemical for reducing the costs to saving. And the otherwise is to using the unused ion-exchanger unit to good performance. By using with the wastewater treatment plant. The feasibility study of the wastewater has been contained a large ion of sulfate are through the cat ion resin. Furthermore in the after treated waste were contained a large of others of cat-ion. When the after treated water flowing into cat-ion resin that. The cat-ion resin will adsorb a large of the others of cat-ion and they will be discharged hydrogen ion to exchanged. As hydrogen ion catching with the sulfate ion performed to the sulfuric acid as low concentration. And because of the wastewater treatment plant has been used sulfuric acid 50% concentration and dose not appropriated to be using for neutralization the pH suddenly. For this reasons its is not matter to expenses. Thus should be dilution the high concentration of sulfuric acid 50% to low by used the sulfuric acid which produced from ion-exchanger and mixing with the sulfuric acid 50% then can be using to good neutralization. In a cycle of ion-exchanger. The ion-exchange resin can not be exchanged and then should be regeneration the resin for recover to formed of hydrogen ion by using the low concentrate of hydrochloric acid flowing through the resin, Wastewater inlet to wastewater treatment plant.
