    Patented biofilm removal for reverse osmosis system - KURIVERTER IK-110

    KURIVERTER® IK-110, the excellent biofilm control agent, is added to feed water line in order to protect the whole RO system against biofouling formation with only one product.

    The concept of water treatment has a direct impact in the reduction of the total cost of operation from reduction of the cleaning process, manpower, chemicals and standby times. When applying KURIVERTER® IK-110 the differential pressure decreases, the loss of flux is reduced, and salt rejection improves.

    Patented rejuvenation concept for damaged membranes - KURIVERTER RC

    Sometimes membranes could be accidentally damaged from oxidizing biocide (such as free chlorine leakage from pretreatment) or other oxidizing substances. KURIVERTER RC could help Kurita’s customers to keep the membrane without losing performance.

    This technology allows us to rejuvenate the membrane, restore salt rejection and postpone membrane change until it is budgeted for and convenient. The rejuvenation process can be carry out very simply using CIP system.
