I have a question: There are substances that tend to precipitate out of wastewater, causing pipes to become clogged or deposits to form in the collection tanks; these deposits are quite hard. Is there any way to deal with this?

I have a question: There are substances in wastewater that tend to precipitate, causing blockages in pipes or the formation of hard deposits in collection tanks. Is there any way to deal with this? It might be calcium sulfate mixed with salicylic acid crystals, etc
Balance acids and bases. Just like when scale forms on your kettle, adding some white vinegar and letting it bubble will cause the scale to come off.
Use the solubility product for a transformation, and then wash with hydrochloric acid
:This is caused by temperature changes. One solution is to maintain a stable temperature, and the other is to dilute the wastewater in advance in order to reduce its concentration. Here, sodium sulfite precipitates and becomes like stone; it cannot be dissolved even with steam, let alone acid
If you are sure it is calcium sulfate scaling, use a calcium sulfate cleaning agent with a pH of 7.0±0.1; it is non-corrosive, reacts rapidly and intensely, and removes calcium sulfate at a rate visible to the naked eye. If you’re interested, I can send you samples for free to test; I guarantee they’ll work well for you. Of course, the prerequisite is that you must be sure the scale sample is calcium sulfate.
