Got results back from an analysis of effluent from the misbehaving ETP at the Indian restaurant which we reconfigured back in the summer of last year.
It appears that now that the plant is being operated and maintained in accordance with our suggestions, the desired increase in performance has been obtained. BOD, suspended solids and ammonia are now well within consents.
It has taken this long for the owners to stop using the powerful alkaline industrial degreasers which made for ease in cleaning, but compromised both grease trap performance and biological treatment efficiency.
We are now helping in their application to the Environment Agency to recommence discharge to environment.
