Description

Memstorâ„¢

Membrane Storage Agent Specialty Chemical

KLT manufactures specialty chemicals in addition to antiscalants and membrane cleaners. These RO/NF specific membrane compatible chemicals work to control bio growth. Microtreat™ BIO loosens bio growth on the membrane surface which can ultimately be removed with a high pH cleaner. Memstor™ is highly effective for short- and long-term membrane preservation with no significant loss in salt rejection upon startup.

We also provide a coagulant, Profloc™ C, which aids in the removal of larger particles by media filters and is compatible with many of our Pretreat Plus line of antiscalants. Our sanitization product, Microclean™ UHP removes free-floating biological organisms in ultra high purity water piping and DI water systems. It’s economical, highly effective and has shorter rinse-up times than similar products containing hydrogen peroxide and peracetic acid such as Minncare.

Memstorâ„¢ safely and effectively prevents microbiological growth within membrane elements and systems during long and short-term storage. It eliminates the need for formaldehyde, sodium metabisulfite, and other chemicals that are either hazardous or unstable. Memstorâ„¢ is effective long-term and is compatible with all membrane types, rinsing easily from membranes. A conductivity meter can conveniently monitor the completeness of rinsing when compared to to the background conductivity of the rinse water. Memstorâ„¢ is packaged as a dry, stable, nonreactive powder for ease of transportation and storage.
