Calcium Hydroxide Products Can Treat the Acid Wastewater

Calcium hydroxide can effectively acid wastewater treatment equipment productsHenan Daswell Machinery Co., Ltd,is a professional manufacturer and trader specializing in the research, development and production of construction machinery for nearly 30 years. Our main products are as follows:SICOMA concrete twin shaft mixer,concrete batching plants,concrete mixer,blocking making machine,concrete pump,etc. Hydrofluoric acid is one of the main solution of dealing with waste water, but hydrofluoric acid after treatment of waste water from acidic wastewater, produced by fluorine ion content is high, before discharge, also need to further processing before they can. The output of the equipment and products of calcium hydroxide is alkaline products, it can effectively handle this acid wastewater. We deal with calcium hydroxide equipment at the same time, you can choose to use lime to remove fluoride ions in solution forced type concrete mixer, using an excess of calcium hydroxide or milk of lime and hydrofluoric acid reacting calcium fluorate precipitation is the most economic and effective treatment method. Using the method of the water so that the precipitation of calcium fluoride fluoride removal from waste water in the. Hydrofluoric acid wastewater treatment should be carried out in the wastewater sedimentation tank mobile block machine, sedimentation tank and the channel should be used after anti-seepage treatment. The process of processing the material into the sedimentation tank and mixing it with the full reaction DMP planetary centrifugal mixer, so that the material is completely mixed. Should pay attention to the process of lime treatment of fluoride containing acidic waste water in a 20mg/L of fluoride, in order to improve the efficiency of fluoride removal, in addition to the input of a certain amount of calcium chloride or aluminum sulfate, can make fluoride ion precipitation more completely, until the free fluoride ion is less than 10 mg after discharge
