Filed:
Apr 17, 2002
Appl. No.:
10/125093
Inventors:
Michael Hedenland - Grass Valley CA, US

Mark Hedenland - Grass Valley CA, US
International Classification:
C02F003/02
US Classification:

Abstract:
A semi batch biological waste treatment process used to treat municipal and industrial wastes containing BOD, nitrogen and phosphorous. The process uses two biological reactors in series, with each maintaining a mixed liquor inventory. Inputs and outputs from the reactor series are performed through the addition and removal of small batches. The reactors can be configured in multiple ways for different waste conditions. The preferred embodiment is an integrated batch process that includes an anoxic equalization vessel, an aerobic biological reactor, a clarification step with denitrification, a tertiary effluent treatment phase with ozone injection and filtration and an automatic sludge wasting method with thickening and stabilization. The process has two denitrification phases and has very high nitrogen removal rates.
