Treatment of abattoir wastewater using a DEGBR with a hybrid membrane bioreactor.xlsx

A Down-flow Expanded Granular Bed Reactor was used to treat abattoir wastewater. a pre-treatment stage with an eco flush to remove FOGs was introduced. The pretreatment duration was a total of 48 hrs (24hrs aeration with a pump + 24hrs of no activity to let the dissolved oxygen levels drop). The pre-treated water will be fed into the reactor then the membrane bioreactor in a continuous process at desires flow rates and HRTs. The sampling times were done 3 times a week and the samples were sent to an external lab for testing.
