I have a similar problem in a municipal water treatment plant. Pressures constantly fluctuate from 75 psi to as high as 115 psi. I think I may have solved the problem. The pressure reducing valve used is a 6" which is too large an it has a minimum flow range. When flow rates are low, the...
I am currently designing a water treatment plant which consists of several independant processes. Prefiltration using an 80 micron automatic backwash prefilter; pH adjustment system; ozonation system and associated injection system; carbon filtration and chlorination. I had a tendancy to rely on...
The detention tank will depend on your design flow rate. For example, if your flow rate is 100 Us gallons per minute, a 50 gallon tank will hold the water for half a minute (30sec). Calculate cubic feet per gallon (0.13368cubic feet per gallon x 50 gallons) = 6.684 cubic foot tank. Depending on...
