I am in the process of putting together a set of design standards for a water company that does both potable water and recycled water distribution. I would like to get a handle on the design standards for the potable water system (pipes, booster stations, wells, etc.). Do any of you have a...
I am new to the water industry. Would like to know more about the differences between VFD and soft start. Terms that are frequenly used in the industry. Trying to get a layman's perspective on this.
Any one has experience treating Fe and Mn using pyrolusite filtration. I am using it in one of my drinking water wells. We are finding breakthroughs happening in short periods of time. We have sanding problems at the well, am wondering if that has anything to do with this. Any input will be...
How do you take a representative sample for odor analysis? I am looking spefically for any H2S odor in distribution water sample. Are there any set protocols like the ones we have for VOCs (viz. no head space, certain kind of sampling bottle, holding time, preservatives, etc.). Any input will be...
The argument I have heard in terms of using polyphosphates for H2S odor is:
H2S can be caused or aggravated by stagnant water and levels of chlorine residual dissipating. The argument is that the (1) polyphosphates reduce the chlorine demand by sequestering cations that exert cl demand, (2)...
Has any one used addition of polyphosphates as a means of removing H2S related odors in drinking water wells. Any input in regards to this will be appreciated. Thanks.
Can someone enlighten me on the Sequestration process. I am not in the water industry and have come across this terminology in some remediation documents I am reviewing. Thanks
I am putting together a small database (excel or access) listing out all water quality parameters (chemical, radiological, biological, etc), MCLs, treatment options, source, etc. Does any one know if there is an already available database out there, the template of which I can use so that I dont...
I am kind of a novice in the field of water treatment. I am wokring in the field of hazardous waste and has a client who has a question regarding reverse osmosis process. Apparently, he is acquiring some interests in some wells, the water from which is being subjected to reverse osmosis...
I have an interview coming up with a water company in Northern California. I am an environmental engineer with several years experience in hazardous waste engineering. Iam really interested in trying out water quality engineering. Please let me know how I should prepare for the interview. Are...
Hi Gary SCWSVI:
Thanks for your response. Can you please recommend a textbook or guidance manual that will give me an idea of the what skill sets to learn and look for in a water quality engineering job. Also, can you please let me know if there are any public or private agencies/companies that...
I have a bachelors in Civil and a masters in Civil/Env. Engg. I have been working in the field of env. engg, predominantly hazardous waste management for the last 9 years. I am also a licensed PE Civil in California. I am thinking of trying out water quality engineering jobs. But I am not sure...
