based on the Principle of Sequencing Batch Reactor Process
owned by a Vegetable Oil Company, represented here as
RWTP. The objectives of this study were to:  Determine
effluent qualities discharge by these two plants.  Determine
the effluent treatment efficiencies of the plants and 
Identify factors, which militate against the performance of
