Industrial effluent

Industrial effluent

Industrial effluent

(OP)
I am in the process of of doing a foul effluent catchment study for a pump station in a large Industial Park. I know the capacity of the pump station and have been asked to calculate what area outside the Industrial park could possibly be catered for by the pumping station if need be?
However I am unsure as to what average flow and peak flow factors I should use in the calculations for effluent discharge from the diiferent sites! The park will comprise of Industry varying from Heavy Biopharma to Warehousing? So average flow & peak flow factors for different types of industry are required    

RE: Industrial effluent

Where are you based?  A good starting point in the UK is find out what trade discharge consents your different companies have.  This will tell you the maximum they can discharge (m3/day), and at what level (BOD, SS, NH3).  You can get these from the EA.

If there are no discharge consents then the foul contributed by each building will be function of its size, number of people using it, type of buildings (office, industrial, school etc).  

There published documents which give indications of loadings per capita, most text books, British Water publish flow and load data for small treatment plants (up to 1000PE).  The average and peak flow factors will be heavily dependent on population(e.g. small populations have a large peak flow over a small duration).  To be really sure you should implement a flow monitoring survey at strategic points within the network.

You may also want to check with the planners and owners of the park to see what has been set in terms of planning horizons.  This will give you an indication of how much growth they expect and will allow you to forecast future flows and loads.


RE: Industrial effluent

As Ussuri noted, peak flows will depend on the size of the project. You are probably looking at 3-4 times the average flow.

Wastewater flows from warehousing are light and typically consist of just the sanitary needs of the workers. That would be about 20 gallons per day per worker.

Heavy Biopharma is a meaningless term. You need to determine what is actually going to be built. It may be just packaging, not production. The wastewater flows from pharmaceutical operations are generally not a significant volume either, but will depend on the type of facility being constructed.

RE: Industrial effluent

Rather than what area could be accommodated why not express it in terms of flow capacity available?

That way one small footprint wet industry could use the total available flow or some dry industry with low water usage could be accommodated?
