FEATURES AND ADVANTAGES
Baslat-C2700 is a liquid formulation designed for use as a high pH cleaner of polyamide thin film composite membrane surfaces.
Baslat-C2700 works to remove the most stubborn biofilms and organic foulants.
Baslat-C2700 supports the cleaning of acid insoluble sulfates of calcium, barium and strontium as well as calcium fluoride.
Baslat-C2700 is especially effective in removal of metal oxide deposits when used in a pH range of 9-10.5.
Baslat-C2700 is buffered so as not to exceed a pH of 12.
Baslat-C2700 may eliminate need for repeat cleanings where severe fouling exists.

CHEMICAL FEEDING AND CONTROL
The cleaning solution should be prepared using potable water that is free of residual chlorine or other oxidizing agents. Add 2 Gal of Baslat-C2700 to every 100gal of water(2% solution). Adjust the pH in the range 10-11. Recirculate the cleaning solution throughout the system, after redirecting the first 20% of the solution to drain. Do not exceed pressures, temperatures and flow rates recommended by the membrane manufacturer. Cleaning efficacy can be further improved by heating the cleaning solution and alternately circulating the solution for 15 minutes and then soaking the membranes for 15 minutes. This should be repeated as many times as necessary. pH range should be monitored periodically throughout the cleaning. When pH drops below the desired range, it should be adjusted by adding more Baslat-C2700. Optimal iron removal occurs at pH of 8.5-10.5.
SAFETY AND HANDLING
Store in a cool, dry and well ventilated area. Keep containers closed. Wash contaminated clothes before re-use. Wash thoroughly after handling. Please see MSDS for more details.
PACKAGING
Baslat-C2700 is packaged in 25 KG non-returnable plastic drums.
