I am looking for vendors (any names of companies) for designing a proposed compound pH system with a flow rate of 6 MGD. I would prefer CO2 for the acid feed and baking soda for the caustic feed. The influent streams has pH varying from 3-10 and hence a pH probe and PLC controller to trigger...
I would like your thoughts on this following scenario.
We have a wastewater basin that has minor contamination of PCBs, metals and the like. The local DEP would like us to remediate and close this basin. Filling in the whole basin with debris is an option but might require a lot earth work...
I have a problem in determining the ponding from a 10 acre developed site with the following parameters.
Rational: A = 10.00 acres; Tc= 15 minutes; c = 0.76;
SCS: A = 10.00 CN = 85; Tc= 15 minutes; Storm Duration = 24 hours; Time Interval – 1 minute; Rainfall: Type – III;
I am trying to...
I am trying to design a oil water separator and need to figure out a worst case concentration for a spill of 20,000 gallons of No. 6 oil say within a time of 4 hours. This is mixed with a peak flow of 7.5 MGD. I was able to do the following:
20000 gallons/hour = 5000 gallons/hour and 7.5 MGD is...
I am in the process of designing a temporary wastewater sedimentation (settling tank) for a coal fired power plant. I am trying to get more information of particle size and settling velocity for coal combustion by-products. The data available based on literature review almost always suggests...

I am working on the grading for the closing of an existing storm water facility with fill and stone (6 inches) of almost 1 acre size in area and 10 feet deep. The closure should provide positive drainage to a regional detention basin
Downstream. Because of the enormous size of fill involved I...
