  • Process for treating waste water
    Patent number: 5976384
    Abstract: A process for treating bacteria laden effluent from a sewage treatment digester to condition the effluent for release into the environment includes the steps of thoroughly mixing the effluent with a bactericide, conveying the mixed effluent to a reaction zone to completely kill any bacteria entrained in the waste water to provide a substantially bacteria free effluent, mixing an oxidant with the bacteria free effluent, maintaining the mixture for a sufficient time to permit substantially complete oxidation and neutralization of entrained bactericide, and discharging the treated effluent into the environment. In an alternative procedure the treated effluent is passed through a neutralizing filtration step to neutralize any active bactericide before the effluent is discharged to the environment.
