Patent ID: 7972515

Claim:
A reverse flow shipboard membrane integrity test system comprising: a separation unit comprising: one or more outer walls; a first inlet conduit for feeding wastewater into the separation unit for treatment thereat; a first outlet conduit for discharging filtered water separated from the wastewater; a second outlet conduit for discharging concentrated liquid waste separated from the wastewater; a membrane arrangement positioned within the one or more outer walls positioned for separating the wastewater into the filtered water and the concentrated liquid waste; an end cap attached to the second outlet conduit, sealing the second outlet conduit; an air supply connected to the first outlet conduit for supplying an airflow to the membrane; a microparticle source containing microparticles connected to the first outlet conduit and the air supply, for injecting microparticles into the airflow forming a test airflow, wherein the test airflow is directed towards the membrane; and a filter positioned over the first inlet conduit for collecting microparticles thereon.
