    Pumping lake water

    If the piping goes up and down mountainous terrain be careful of pulling a vacuum on the piping. Column separation of the water in the pipe could. The vacuum will collapse the pipe. The solution is to introduce vacuum relief valves

    GAC Backwash intervals

    A suggested weekly or bi weekly backwash is too long a period of time between backwashes. In a municipal potable water treatment facility the decision to backwash any filter will be based on three criteria. They are terminal headloss, service time between backwashes and turbidity whichever...

    How to estimate heat load for machinery

    If the motor is 75 kw and the actual running load is 68 kw and the motor is 90% efficient ,,,, the reject heat from the motor is 6.8 kw (10% of 68). The rest of the energy is going into driving your equipment. What is the mechanical equipment actually doing? Is it some sort of conveyor system?

    Pump-Motor issue

    If the discharge piping has victaulic couplings or something similar the internal liquid pressure will cause the piping to push against the pump and move the pump. That in turn will cause misalignment between the pump and motor and will cause vibration issues. When using victaulic couplings...

    Corrosive atmosphere from leaking hypochlorite tank?

    HCL off gassing will cause immediate corrosion. This would have caused severe corrosion. Sodium hypochlorite leaks and off gassing will corrode equipment metallic surfaces over time when the atmosphere is moist. You will see white powder on galvanized conduit, and blue green powder on copper...

    Degassing of high points in in sludge lines

    I do not know the layout of your plant but trying to make a square peg fit into a round hole sometimes makes people think about really weird solutions. You get twisted in a knot. And then when it does not work all the logic you used to convince yourself back then about why it would work all of...

    Pyrolysis of Contaminated Waste Thin Film Plastics to Char

    Dave, let it go and get some sleep

    Pyrolysis of Contaminated Waste Thin Film Plastics to Char

    ....While Dave may not be expressing himself in the best manner... Dave, we will agree to disagree. Just chill out and leave it at that.

    TugboatEng, I am not sure what pragmatism has to do with Dave's approach on how to communicate with people he disagrees with.

    Degassing of high points in in sludge lines

    The last thing you want is explosive digested gas being released into a room via an air release valve or a manual bleed valve

    Dave may be a valuable contributor. But his Dick Tracy routine and accusations approach turns me off. Over and Out

    Pyrolysis of Contaminated Waste Thin Film Plastics to Char

    I hear you about the fuel cell analogy. The oil/gas/plastics industry would partially fund the work and apply for more grants from the EPA (or the USDOE etc). In order to get grants from the EPA you basically have to have a US company be the front man. The oil/gas/plastics industry have a lot...

    Pyrolysis of Contaminated Waste Thin Film Plastics to Char

    Dave, please go away. You are so annoying. Get a life. I have to go back through my emails to find the correct name of the organization that I spoke to AND I am certainly not going to do it for you.

    Pyrolysis of Contaminated Waste Thin Film Plastics to Char

    I understand the obstacle regarding the optics of "burnt" plastics. Plastics have a bad image. I am betting on changing the image by making char. It does not even look like a plastic anymore. That is why I want to get EPA funding and Plastics Industry Funding.

    Pyrolysis of Contaminated Waste Thin Film Plastics to Char

    EPA has the funding money for the research (Same for the Department of Energy and the plastics industry). They set the laws and rules. If the EPA says don't dump plastic then the states and municipalities have to follow the law. Municipalities won't spend money to stop dumping of plastic if it...

    Pyrolysis of Contaminated Waste Thin Film Plastics to Char

    No, I did not kill the concept of pyrolysis. It was sarcasm. I just got turned off by Dave. The investment to move this forward requires private and government investment. Preferably, the EPA, Department of Energy and the Plastics industry in collaboration

    Degassing of high points in in sludge lines

    look closer at moving equipment and piping around to get the sloping and do it right the first time. no one is going to thank you when the half ass solution does not work. wasted time and money

    Pyrolysis of Contaminated Waste Thin Film Plastics to Char

    There is plenty of research going on to convert plastics to their constituent monomers and repolymerise back into polymers. The solution to the plastics problem will require a multiprong approach. No one solution will fit the bill The problem with converting plastics to their constituent...
