The sludge discharge from the preprocessor can occur either from the top or from the bottom, with the clear liquid flowing out from the middle. The amount of sludge floating on the surface of the preprocessor depends on certain factors; sometimes there is more sludge, and other times less. The presence of bubbles on the surface is also influenced by certain factors – under the same air pressure, there can be more or fewer bubbles, and these bubbles can be large or small. What determines these factors? Will the complete removal of the sludge from the lower layer cause the saltwater to become turbid again? Is it necessary to remove the floating sludge when there is no such sludge present? :lol # , , &
1. The amount of sludge on the surface of the preprocessor depends on the amount of ferric chloride added to the saltwater and the magnesium content in that saltwater. The amount of ferric chloride and the magnesium level determine the quantities of magnesium hydroxide and iron hydroxide, which are the main components of this sludge. 2. The number of bubbles on the surface of the preprocessor depends on the amount of saline water entering the preprocessor and the amount of supersaturated air contained in each unit volume of saline water; the amount of supersaturated air per unit volume of saline water is in turn related to the pressure of the air compressor and the system temperature. At the same time, the number of bubbles is also related to the atmospheric pressure at the site, the temperature of the preprocessor, and the liquid level. The size of the bubbles is mainly influenced by the amount of air supersaturated in the brine and the flow rate of the brine. 3. Under normal conditions, all sludge is removed through the lower sludge discharge mechanism in the preprocessor, which prevents the saline solution from becoming turbid; the upper sludge discharge is carried out as needed, and there is no need for any fixed rules regarding it.

1. How can the amount of ferric trichloride to be added be calculated theoretically, and what are the criteria for such calculation? 2. In my opinion, even when the saltwater flow rate and air pressure remain constant, the number of bubbles varies; why is this? The system temperature, local atmospheric pressure, etc., are all relatively stable. 3. Thank you
