[0002] In modern society, people pay special attention to whether the water quality standards for daily drinking water are met. The quality of water is closely related to the water purification process. In the water purification process, we often use reverse osmosis water treatment equipment. Reverse osmosis water treatment equipment usually passes raw water through precision filters, granular activated carbon filters, compressed activated carbon filters, etc., and then pressurizes it through a pump. It uses a reverse osmosis membrane with a pore size of 1 / 10000μm to convert high-concentration water into low-concentration water, and at the same time isolates all impurities in the water. The reverse osmosis membrane is the key equipment of the reverse osmosis system. When the system runs continuously for a long time, calcium and magnesium ions in the water will continue to precipitate and attach to the surface of the reverse osmosis membrane, forming scale to block the membrane pores, which will affect the water output efficiency of the reverse osmosis system and damage the reverse osmosis membrane. In order to protect the reverse osmosis membrane, we often need to use an antiscalant dosing device to delay the precipitation of calcium and magnesium ions and scaling on the membrane surface.
[0003] The existing devices for adding antiscaling agents either require manual addition, which is time-consuming and laborious, or the antiscaling agents are automatically added by controlling a switch through a control device, which increases the cost of use.
