All,
I need to know the factors effecting the accuracy of a clamp-on ultrasonic flow meter. I recently purchased one to do some in-plant potable water conservation work. It was an Economy-bay model and the tech support is non-existent, but it was what I could sneak in under the budget. It...
I work for a company that occasionally acquires industrial sites. I have recently been moved into a position that deals more directly with these transactions. I have not had this issue come up specifically yet, but want to be prepared if/when it does, as it seems likely to happen sooner or...
I am registered in the state of Pennsylvania. I was recently informed that it is mandatory to sign with a PE after my name and it must be on my business cards. I had some old cards and was using them up, as I had never heard this before. I couldn't find this in a search, but maybe I'm not...
All,
I am relatively new to the industrial arena, being a civil/environmental most of my career. Therefore some of the questions I have about plastics and polymers may be very elementary, I apologize in advance. I am currently working for a food processing company that uses batch retorts in...
I am currently overseeing construction of an industrial WWTP. The influent has alot of organic material that we are feeding to an anaerobic digester. The influent passes through chopper pumps prior to entering the digester.
Because this is an industrial plant we sometimes have nuts, bolts...
One of our contractors has constructed an elevated slab with several pipe penetrations. The slab supports two vertical turbine pumps and a suction lift high pressure pump. The piping is all ductile iron flanged pipe.
Details: 10'x18'-10" thick elevated slab above wetwell with two mats of...
Hello,
My experience is civil/site with some wastewater background. The company I'm working for needs to expand its wastewater effluent pump station. The current system is a duplex submersible going to approx 1 mile of 6" force main. With increased flows it appears they will need to add...
I was asked to review a reinforced concrete footing/pier which supports a steel canopy. After review the footing meets code and is more than adequate, but the pier has less than the code required long. steel for columns (<0.3%). The pier meets the criteria for mass concrete dimensionally, but...
I am currently reviewing the design for several circular wastewater treatment tanks in an area with an unpredicatble water table. The tanks are 18' deep and 95' & 60' in diameter. The design calls for rock anchors to resist uplift. The opinion of our staff is that a drainage system under the...
I am reviewing plans for an industrial (food processing) wastewater treatment plant. The plant influent contains fruit skins that tend to hang up on exposed edges. They then build up rapidly to a full clog. The valves for the project are specified as plug valves. I agree with this in...
I have been doing site work for awhile, but haven't had to do alot of LPSS work. I was given a project to design with a network of nine closely spaced grinder pumps and about 2,000 LF of force main. The profile has a "hump" in the middle with the discharge manhole at the same elevation or...
