Treatment of industrial wastes
Treatment of industrial wastes
(OP)
I want to arrive at a convenient method, to treat liquid waste from a petrochemical plant. My main aim would be to reduce the BOD, TSS,TN, and TP content of the waste stream down to acceptable levels before discharge into the public system.
Design capacity ought to be around 10 million cubic ,meters per year.
How do I go about solving this one?

RE: Treatment of industrial wastes
If so, Your only practical alternative is biological treatment, e.g., an activated sludge system.
If you post details, I will try to help.
RE: Treatment of industrial wastes
5.5 million GPD sounds about correct.
Why activated sludge though? Any particular reason?
Basic objective would be to neutralize and/or reduce the hazardous characteristics of the influent stream as characterized below, before discharge into the public domain

RE: Treatment of industrial wastes
I will have to review your data. Maybe you could look into equalization initially. Combine the discharges. Maybe there is a dilution. If the regulatory agencies allow that. But my first guess was the AS because of the large flow rate.
I'll try to reply soon.
RE: Treatment of industrial wastes
Are the wastewater streams fairly continuous? Look at equalizing the wastestreams, calculate the concentrations and loads in the final combined discharged. That may meet your acceptable limits.

Just a thought.

Electrolytic treatment with subsurface aeration using membrane diffusers would reduce or eleiminate 90% of this. The treatment area would be small, and be vastly superior.
