SD-150 Antiscalant and Dispersant for
SD-150 is a high-effective scale inhibitor, it is suitable for reverse osmose (RO), nanofiltration (NF) and ultrafiltration (UF) system. SD-150 can inhibit the scale deposit on membrane surface, improve water quality, lower operation expanse. SD-150 has the following properties:
1.  Used together with organic flocculants.
2.  Used for drinking water system.
3.  Inhibit scales formation of calcium carbonate, calcium sulfate, barium sulfate and strontrium sulfate, no scale is formed even when LSI value is 3.0.
4.  Used for almost all RO membranes.
5.  Maintain the surface of RO membrane clean by dispersing particle blockage.
6.  Effective in pH 5-9.
7.  Used directly, or after dilution.
8. Good resistance to aluminia oxide and ferric oxide.
