NC-505 Reverse Osmosis Membrane Cleaning Agent(equivalent to
American GE-BETZ kleen MCT511)
(1) Properties:
a. It can reach the best effect when using together with NC-504
& NC-502.
b. It is very effective to remove the oily sustances and other
organics.
c. It shows excellent effect for removing biological sludge.
d. The pH value of diluted solution must be kept between 10.5+-0.5.
e. The liquid agent can shorten the mixing time, and can use
easily.
(2) Specifications:
Appearance | Amber yellow solution |
Solid content, % >= | 52 |
pH <= | 12 |
Freezing Point | - 7oC |
Density (20oC), g/cm3, >= | 1.189 |
(3) Use Way:
NC-505 is high pH-value liquid formula. It is mainly used for
removing organics, sludge and other granules attached to the
membrane surface. It is suitable for aromatic polyamide reverse
osmosis membrane, acetic acid membranes, hollow fiber membrane and
NF and super filtration membrane. Its excellent cleaning effects
must prolong the membrane's operation time.
To get better effect, you'd better use it together with NC-504
& NC-502.
(4) Cleaning Way:
A. Usually add this product according to the system water quantity
(including cleaning tank, connection pipes, pressure container and
membrane). Dilute it until the concentration is reduced to 1-3%,
i.e. add 10-30 kg of this product in 1 tons of water.
B. Check cleaning tank, soft pipes and security filter.
C. In accordance with A calculated system water quantity, use
anti-osmotic water or salt-removing water to cleaning tank. Slowly
add 10-30kgs of this product in each 1 tons of water to the
cleaning tank, and mix the solution with circulating cleaning pump,
and heat it 35 -40oC or the maximum temperature regulated by the membrane
manufacturer.
Circulate and clean 30 minutes in the inlet direction, clean flow
must be in accordance with the recommended value of membrane
manufacturer and system provider. If you can't find this value, you
should adopt low-pressure, low-speed, small-flow to clean it.
Before entering RO, you must filtrate through 3-5 m filter. The
outlet flux are as follows: For 2.5 inches RO component, the outlet
flux is 0.6-0.68m3/h; For 8 inches RO component, the outlet flux is 6.0-6.8 m3/h; If 4 inches RO component, the outlet flux is 1.5-1.8 m3/h.
If the pollution is serious, please let out the initial flowback
liquid (the volume is about 15% cleaning tank) to prevent the
polluted materials from sticking on the membrane surface. Before
renewal the system and operate it, you'd better use the reverse
osmosis membrane to clean through water.
(5) Security Attention Items:
Please refer to our company's MSDS.
(6) Packaging & Storage:
Packed in 25 kg or 200 kg plastic drums. Storage is one year.
