Dear colleagues, I am are looking for valves that can be programmed to shut off after a pre-determined volume of water has flowed. Any information or leads on likely valve manufacturers are gratefuly welcome. Thanks

submersible pump required for a power plant. Fluid is mainly hot water (95 - 100C), not toxic or inflammable and it needs to be pumped from a tank to a height of about 5meters. Average flow rate: 100 m3 per hour. Frequent breakdown of present pumps (electric motors) because of temperature...

Thank you matt and dubmac. I will get some fluid properties and pump specs from the project team in my next post.

i am looking for pumps that can deliver at process fluid temperatures of 95 deg Celcius and above. Any leads on vendors in the US or Europe highly appreciated.

Any practical experience with ammonia stripping? We are at the planning stage of treating a 60m3 per day of ammonia wastewater - with ammonium levels at 50 - 100ppm. We will vent the stripped NH3 to air. NH3 stripping depends on pH and temperature. I would to know from anyone with practical...

I am developing a program to remove NH3 from wastewater (ammonia; 500-600mg/L) by using sodium hypochlorite to oxidize ammonia. Has anyone any experience with this kind of application? A literature search shows that it can be done at pH 7 - 8 and controlled by ORP. I cannot find any ORP value to...
