MEM-SHIELD is based on the MINT’s patented Membrane Integrity Sensor (MIS) which monitors the quality of MF/UF permeate and translates the data inot membrane integrity status and Log Removal Values (LRV). It is able to reliably and accurate detect problems with membrane integrity.
MEM-SHIELD is installed on the permeate line of the pressure membrane system. Depending on operator requirements, multiple sensors can be installed in order to pinpoint damaged modules. The integrity sensor detects minute changes in water quality, which in turns indicates the integrity status of the membranes. If a membrane module is damaged, the MIS-monitoring system indicates to the operator that an error has occurred. The MIS-LRV system then quantifies the magnitude of the integrity breach, and gives an indication of the LRV value of the membrane.
