Project TitleContinuous Water Flow Sampler (COFLOWS)
Track CodeLSU-2016-028
Short Description

This invention is a submersible container used to determine oil concentrations in large bodies of water. Currently used water samplers only allow a discrete amount of water to be sampled at once, limiting sample size and oil concentration accuracy. The COFLOWS (Continuous Flow Water Sampler) system overcomes this by continuously forcing water through the system capturing any oil present in the water within a dynamic absorbent cloth. The oil concentration in the water is then estimated based on the amount of water forced through the system, which is monitored by a water flowmeter, and the amount of oil within the cloth.
