Fluoride removal part of activated alumina in mineral water
Now we talk about the mineral water of fluoride removal by activated alumina impact.
Generally, at the starting of a semester, right after just after the final cycle of regeneration of activated alumina adsorption is stronger, the concentration of fluoride within the water at this time for you to zero. As the operate cycle in the method and began began detects the presence of fluoride ions in the water, adsorption column is inside the course of action of becoming penetrated; fluoride concentrations improved swiftly thereafter, and soon water fluoride concentrations close to the water level, sorbent adsorption capacity of activated alumina lost, an end of your operate cycle
Along with the regeneration method begins. While the maximum permissible concentration for fluoride in drinking water is 1.5mg/l, but within the actual production method, taking into account security components, when the water fluoride concentration of a production cycle will finish when 1.2mg/l, the regeneration approach starts. So we paid attention to when the water fluoride concentration reaches a 1.2mg/l of activated alumina adsorption capacity. Approach 1 activated alumina isn't activated, so the adsorption capacity of activated alumina in the process 1 1.06g/l, but less than two, three 1.43g/l, 1.44g/l. 2 and three processes due to the condition of your course is fantastic, significantly less sorbent regeneration and its adsorption capacity reached a peak at work. So we believe about water, extremes in the adsorption capacity of activated alumina in 1.44g/l/; maximum treatment capacity in 520BV. With enhance of sorbent regeneration times, gradual reduction inside the adsorption capacity of activated alumina,
So the production capacity as a way to hold the technique steady need to be updated frequently part of adsorbent. The truth is when the water fluoride concentration reached when 1.2mg/l, if a bottle of activated alumina in not totally saturated, it is absorption capacity totally saturated activated alumina accomplished only about 75%. To be able to take full benefit of active enrollment of oxide adsorption capacities in industrial equipment design and style can take many precise industrial processes, for example two remedy crossover alternating operating. In the starting of every single production course of action, impact regeneration because of the effluent is not steady, the water cannot be applied because the final solution of this stage, had to be dropped. This process in about 50 BV.
