THASD-200 Antiscalant and Dispersant for RO Membrane


THASD-200 is used for RO, NF and UF system, it can effectively inhibit scaling on membrane surface, improve water quality and lower operation cost. THASD-200 has the following properties:

1.  Original liquid is 11 times concentrate, 90% transportation cost and storage space is saved.

2.  Prevent pollution from inorganic salt, metal scale and some organic substances.

3.  Not flocculate with ferric oxide, aluminia oxide or silica oxide to form suspended substance.

4.  Effectively control the pollution of ferric, aluminium and heavy metal.

5.  No content of any phosphate of phosphorous.

6.  Used in RO CA, TFC, NF and UF membranes.

7.  Good solubility and stability.

8.  Stable in extreme pH and temperature.

9.  Due to THASD-200 special molecular structure, it is safe to membrane. Even high medicine input (equipment trouble, for example) will not lead to its deposit, crystallization or adsorption on membrane surface and lead to membrane blockage.
