    Technical Opinion on SS304 Potable Water Line Leakage

    Hi, Attached standard in Thailand on drinking water: https://wepa-db.net/archive/policies/law/thailand/std_drinking.htm People don't drink tap water in Thailand unless they have no other option. Definitely SS304 is a bad choice, most of the time people are using PE pipe. Pierre

    Cooling mixing tanks with a chiller, selecting chiller size

    My points are the followings, *Understand the problem with current water system (quality, quantity, temperature), ** Design your system for current and future applications (Capacity, Operation, Maintenance) *** Perform the economics for all the possible solutions (chillers being one of them)...

    Cooling mixing tanks with a chiller, selecting chiller size

    OK, I'm out. You need to design your system from scratch. In any cases you definitely need to analyze your raw water, a third-party lab could easily do the job. I don't believe hardness is responsible for your "pitting issue" especially because you operate an open system, you may have other...

    Cooling mixing tanks with a chiller, selecting chiller size

    Hi, Agree with proposals above, But if your main issue is the quality of water not the supply, I will consider treatment like Resins. Nowadays you can buy no intrusive meter to measure flow rate (Based on Doppler effect). For the chiller option, I will select multi units to adjust the cooling...

    Fan upstream or downstream of a scrubber

    Hi, A google search. Pierre In a wet scrubber system, the fan can be located either upstream or downstream of the scrubbing column. Placing the fan upstream can help reduce the fan's exposure to corrosive or dirty gases, while downstream placement allows for greater flexibility in system...

    Dual Media filter vs Pressure sand filter

    Get a chemical engineer involved! Sand filter is for raw water, coarse filtration, AC filter is a polishing filter. Note: AC technology is good for Hydrocarbon removal, but you need to be able to regenerate/dispose them Good luck Pierre
