The BIO-PURE batch process is programmed through a microprocessor to provide consistant treatment regardless of the erratic flows encountered from domestic wastewater systems. The turbulent action of airflow results in the attrition of all degradable solids entering the plant after passing through the disintegrator, influent collects in the aeration chamber where it is mixed with biologically active mixed liquor and digest.
The aeration chamber remains at least one-fourth full at all times in order to provide a basic colony of bacteria for digestion of fresh influent. The aeration chamber also serves as a surge tank for variable influent flow rates (33% of daily flow).
When the level in the aeration chamber rises to the standby level float switch, this starts the batch cycle. Mixed liquor is then transferred to the clarifier accompanied by a minimum two minute automatic skimming of floatable solids back to the aeration chamber. Quiescent settling then takes place for sixty minutes.
Now the Ozone contact chamber is ready to receive the clarified supernatant, as prior to the supernatant transfer 95% of the contents of the ozone chamber have been discharged through a filter to the receiving facility (field, pond, stream, river, or lake) ; the remaining 5% is returned to the aeration chamber for further treatment.
Ozone contact time is approximately 45 minutes, with an additional 15 minutes of settling for a total of 60 minutes of retention time. After 60 minutes 95% of the contents of the ozone chamber are discharged through a filter to the receiving facility (field, pond, stream, river, or lake); the remaining 5% is returned to the aeration chamber for further treatment.
