Study: Ozone still out on its own as RAS water treatment

(01/10/19)

A trial by researchers in the United States has shown that semi-continuous dosing of the industrial disinfectant peracetic acid (PAA) cannot be used as a direct alternative to low-dose ozone in recirculating aquaculture systems (RAS).

Ozone improves the RAS environment by enhancing water clarity, microflocculating fine solids, adding oxygen, and reducing dissolved metals, nitrite, and organic concentrations.

But it is also relatively expensive and complex to use and can present safety hazards for............................................................
