Today we will mainly focus on how to solve itreverse osmosis equipmentThe problem of scaling in concentrated water? solvereverse osmosis equipmentThere are many methods for scaling in concentrated water, depending on the water quality. The general methods are as follows:

1.Control the entire system wellPHKeeping it in an acidic state can effectively prevent scaling, especially calcium carbonate*...However, the disadvantage of this method is that it produces carbon dioxide, which cannot be removed in the system and can corrode and affect the equipment. If controlledPHbe in8.2Left and right, it can be converted into carbonic acid and then removed, but attention should be paid to precipitation, and the balance should be controlled by yourself.

2.Add descaling agent. The function of descaling agents is to form a film on the surface of crystals and colloids, preventing them from binding and only delaying the process. When the ion concentration reaches a certain level, scaling and precipitation will occur, so it is necessary to control the gas recovery rate. Adding too little scaling agent will not work, and adding too much will also form sediment. Therefore, it is necessary to control the amount and choose carefully. Different scaling agents target different sediments, and the selection should be targeted.

3.Add flocculant.PAC PAMThey are all good choices. I usually use them interchangeably, but I need to calculate the amount according to the reaction equation. I cannot add too much because it is also a pollutant. Filter and remove the formed precipitate.
