To date, the use of DAF had a mixed success bacause of the differences of seawater and fresh water for which most DAF technologies are developed. Main differences entail water density and the need ot operate at higher pressures, the size of marine algae which often are an order of magnitude smaller than fresh water algae and therefore require the use of smaller size bubbles, and the charge of seawter particles, which usually is signficnalty lower than that of fresh water particles and therefore requires re-design on the coagulation and flocculation chambers.
