Summary Polyaluminium Chloride pharmaceutical test to meet what the requirements are qualified? Summary Polyaluminium Chloride pharmaceutical test to meet what the requirements are qualified? A sewage treatment station in Fujian is pulping and papermaking wastewater. Now, there are several suppliers of polyaluminum chloride pharmaceuticals to this water station. However, this water station has little understanding of this area, so I would like to know how to know the quality of polyaluminum chloride Good or bad, the current method is to determine which pharmacy through a small test is good. Then, polyaluminium chloride pharmaceutical small trials need to reach what requirements be considered eligible, such as COD removal rate to achieve how much, from the alum after settling time and so on. Put into the system trial, to achieve what standard? There is another for a polyaluminum chloride, biochemical segment of the micro-organisms is it right? Have to take some time to adapt to the new water quality? Today, the filter source of water will be for you to explain a class of problems. In fact, to determine whether a drug is qualified, you can test its effective content. Because of water quality, pharmaceuticals are not the same, each agent on the COD removal rate will be different. So can not simply pass the removal rate to determine the eligibility of the drug. Proposed, you can take these several suppliers of Poly aluminum chloride pharmaceutical company to do a small test, the same kind of waste water to join the same amount of polyaluminum chloride (preferably the amount of polyaluminum chloride is not enough), stirring the same reaction time After the observation alum size, sedimentation rate, compare the COD removal rate of different agents, through these comparative data to determine which agent is better, integrated into a lower. The general precipitation of aluminum salt pH 5.8 ~ 8. Biochemical wastewater into the pH value must be transferred to more than 6.5. Above this pH, the aluminum salts have completely precipitated and are not expected to affect the microorganisms. If your polyaluminum chloride does not contain any other ingredients that are harmful to microorganisms, then do not worry if it is harmful to the biochemical system and does not require adaptation. Before entering the system, it is best to pick a good polyaluminium chloride, that is, efficient, safe polyaluminium chloride. Of course, the content must also meet the requirements of friends.
