Clean Beach Treatment System
for Safer Swimming
Clean Beach Treatment System is a chemical-free process that creates an in-situ swimming pool. The system provides safe, clean water for users and minimizes beach closings due to algae and E. coli.
A five-sided barrier creates an “exclosure” of the swimming area. Beach water is pumped to an onshore facility which filters and returns clean water. Since deployment, no beach closings have been issued.
