NC-509 Reverse Osmosis Membrane Anti-scaling Agent(equivalent to American GE product- MDC 151)

This product is equivalent to American GE product-MDC151. It is the twice concentrated solution of NC 511 (equivalent to American GE product - MDC150). It is a kind of high efficient reverse osmosis membrane inhibitor. As it is the concentrated solution, it can save transportation cost considerably. It should be diluted more than 1 time than NC-511. The dosage is 3mg/l.

(1) Performance of NC-509:
     a. It can effectively control the scales of calcium phosphate, calcium sulfate, barium sulfate and strontium sulfate. Even as high as + 3 LSI, it will not scale.
     b. It will scatter the particles deposited on the surface of the RO membrane, keep the membrane surface clean and will not block any more.
     c. It can be used in almost all reverse osmosis membranes (RO).
     d. This product is compatible with the flocculants composed by equimolecular quantity polymers like NC - 520 flocculants. It has advantages such as not producing deposits.
    e. It has good tolerance to ferric oxides.
f. Use this product when the water's pH is between 5-9, which is still its effective range.

(2) Use Way of NC-509:
When using this product, please do not dilute it more than 10 times. The normal dosage is 1-3mg/l.
