The touch screen is programmed to continuously upload data to LWR's server every 5 minutes for analysis, provided the internet connection is working. This includes flow data and TSS values if grõCONTROL is included. The operator will also need to ...
9. Calibrating Chemical Feed Pumps
CALIBRATION OF CHEMICAL FEED PUMPS: The chemical feed pumps actual flow rates can differ from the calculated flow rate by as much as 2 times depending on the amount of back pressure provided by the process fluid. The pumps must be calibrated to ...
10. GRUNDFOS TRANSFER PUMP DESCALING
The transfer pump P-210 will have scale deposits build up on the impellors and bearings in the pump. This will lead to reduced pumping performance and eventually to the pump stalling. The scale is comprised of a mineral and iron scale. This scale is ...
11. GRUNDFOS AIR BLEED
The transfer pump P-210 and Clean-in-Place pump P-360 won’t function if there is any air trapped inside of the pump. The transfer pump will require bleeding any time the water has been drained out of it. Occasionally the Clean-in-Place pump will suck ...
