I would like to ask for methods to treat saltwater turbidity:

Precursor processor turbidity recurrence phenomenon and treatment Sequence Number Cause of turbidity Treatment measures 1 Low pressure in the dissolved air tank Adjust the air pressure supplied to the tank or ask the air compressor station to increase it 2 Liquid level in the dissolved air tank is too high or too low Adjust the inlet and outlet valves of the tank to control the liquid level 3 Excessive or insufficient amount of ferric chloride solution added Adjust the flow rate of ferric chloride to maintain an appropriate level 4 Unstable or excessively high temperature of the brine, affecting the amount of dissolved air Maintain the brine temperature at (55±2) 5 Unstable brine flow rate Keep the flow rate within 5 cubic meters per hour 6 Unstable brine concentration Control the interval between salt additions 7 Delayed sludge removal Carry out timely upper and lower sludge removal 8 Poor quality of raw salt 9 Excessive amount of salt sludge in the precursor processor Clean the salt dissolving tank and the precursor processor promptly

Poster: We have already investigated the reasons in this regard, but they are not the issues you mentioned. I suspect other factors could be at play: for example, the volume of the pre-reactor tank, the reaction time, etc. The system was working well some time ago, and we also checked the pre-processor; there was no sludge or fine salts present.

It is recommended that the poster check the dimensions of the nozzles in the soda mixer and the Venturi mixer to see whether they are manufactured according to the designed dimensions, or whether their inner diameter has changed due to anti-corrosion treatment.

We have encountered this issue as well, but it has now been effectively addressed; the water output is clear. You can look for causes in the following areas: 1. The quality of the raw salt – the poster mentioned that the magnesium content can reach 0.11%, which is indeed a low level. So it can be basically ruled out. 2. Regarding the storage of raw salt, are there many different types of salt? Is it the messy stacking that causes the uneven application of salt? 3. Is the excess alkalinity of the saltwater controlled automatically online? If not, it is difficult to ensure stable control. 4. Control of brine flow rate: this is due to pneumatic regulation as well as fluctuations in the compressed air pressure in the pressurized dissolved air tank. 5. The amount of ferric trichloride added is important; too much or too little is not favorable. 6. The issue of sludge discharge was also dismissed by the original poster. 7. The issue with the soda mixture: as mentioned above, it is possible that there is a problem with the mixer. 8. Is the concentration unstable? If salt is applied using a loader, this is inevitable; whereas continuous application of salt via a belt results in more stable control.

Please discuss the various causes of turbidity in saltwater and the corresponding treatment methods. Thank you

It must be that the temperature of the saltwater decreases, resulting in a lower solubility

Thank you all for your participation; special thanks to my colleagues on the second floor

No need to thank me; we should help each other, right? I’m just not sure if my answer can help you solve your problem

Poster: When we first started using the water, its quality was good and there was no sedimentation; however, since winter began, this phenomenon has become quite noticeable. We have also checked the ferric chloride level, and there are no issues with it； For adding salt, we also do it continuously, using conveyor belts for transportation ； The types of salt are also quite limited; it’s sea salt from the Bohai Sea area near Weifang. The only issue left is the one related to the mixer, as mentioned by the original poster. Thank you all for your guidance. This post was last edited by limingshuguang on 2008-1-14 13:09.]
