Return to turbidity and transparency
Thread Content
This post was last posted by sunjl1981 on 2013-1-6 23:38 Hello, editors, I have a simple question to ask about the relationship between the turbidity and transparency of brine. I personally think that a higher transparency of brine means that the brine is clear but not turbid. But sometimes I heard that the salt water is turbid but the transparency is high, but the saltwater is turbid. What is the turbidity of brine pretreatment? Sometimes the brine flowing out of the overflow port of the preprocessor is white, just like milk, sometimes the color is red, sometimes the brine is black, and sometimes there are granular substances. In short, I don’t know where the problem lies and whether the condition of the brine is good or bad. Please help experts. This post was last edited by LMT168 on 2008-1-9 14:56 ] # , , &
The terms used in production are different from the concepts in books.: The return of turbidity in salt water generally means that the salt water sediment is not separated (that is, a suspension is formed) ； The transparency of salt water generally refers to the see-through condition of the salt water after sufficient precipitation. So turbidity and transparency are two different concepts. The return of brine to muddy water is mainly caused by specific gravity, viscosity, sedimentation time, brine flow rate and other reasons. The poor transparency of brine is mainly caused by the incomplete removal of colored ions or the precipitated particles being too small to be separated by precipitation.
Thanks for the explanation upstairs, but I still don’t understand. Logically speaking, the production specific gravity, viscosity, sedimentation time, brine flow rate, etc. of continuous operation should be stable. The transparency of brine is sometimes high and sometimes low. The brine coming out of the overflow port is sometimes like milk, sometimes like muddy water.
①The NaCl content of crude brine is unstable. ② The NaOH content of crude brine is unstable. ③ The Na2CO3 content is too high before pretreatment. ④ The temperature of crude brine fluctuates greatly. ⑤ The flow rate of crude brine fluctuates greatly. ⑥ The dissolved gas content of crude brine is insufficient. ⑦ The mud discharge is not timely.
Why is the mud discharge sequence wrong? What is the basis for the amount of ferric chloride added? How to control the amount of dissolved gas in salt water? Our pressure has always been relatively stable, and others have been relatively stable.
The amount of dissolved air only needs to be controlled to stabilize the pressure. The amount of ferric chloride can be adjusted according to the color of the upper mud. Generally, it is slightly red.
