I am developing an expected energy output analysis for a solar farm based on a "12x24" standard test condition scenario. Based on my findings I will create a lifecycle analysis of the solar farm. I have looked on the internet and in my old text books for a methodology to solve this problem...

Micrograms per litre is correct. My mistake. The regulators are trying to adhere to a future California Toxic Rule standard that will be enforced as of 2010. I am of the opinion that the State Water Quality Control Board will see eventually see the error of their ways and relax the standard...

Thanks for the lead and the warning.

I have and here is the comparison I found: USBF vs. MBR (Zenon) • The USBF system has a smaller foot print than the Zenon MBR process and the capital investment is about 70% less than that of a Zenon MBR system. • The Zenon process requires a biological treatment system and chemicals in order...

Can you suggest any suppliers that I can engage?

That is a very good question. I need to check the regulatory requirements but as long as we meet BOD, TSS and nitrate levels (10/10/10) we should be OK. What does your experience tell you about how the TDS will affect these levels?

I am trying to provide a solution for a domestic wastewater treatment problem that has unique constituents that are very difficult to get rid of. I believe that I can handle all the organics including TSS, BOD and nitrate levels with an Upflow Sludge Blanket Filtration (USBF) system, but I have...

I am a Civil PE designing a solar array for a roof top application. I am proposing a structural design that will end up being submitted to a Structural PE for approval. My concept design includes using a commercially manufactured support system that incorporates either lag bolts or tek screws...
