191 is a liquid scale inhibitor / dispersant with high efficiency. It is used to control the scaling caused by CaCO3, CaSO4, BaSO4, SrSO4 and ferric oxide precipitation in membrane separation system, which is suitable for a wide range of water sources. The cleaning period of the system can be prolonged by using the scale inhibitor, and the membrane life can be prolonged and the cost reduced.
1.Effectively controlling the scaling of calcium carbonate, barium sulfate and strontium sulfate. The value of L.S.I is as high as 3.0.
2.Excellent performance, green environment, no phosphorus, high safety to reverse osmosis system.
3.Dispersion of blocking particles to maintain the surface of reverse osmosis membrane clean.
4.Suitable for the United States Hyde Neng membrane, the United States Dow membrane, the United States universal fluid membrane, Japan Toray membrane, South Korea film and other main reverse osmosis membrane.
5.The pH range of influent from 5 to 9 is still within the effective range.
6.Can be added directly to the original solution or diluted.
