“Draw a water-treatment coagulation P&ID with raw water, coagulant and pH reagent tanks, transfer and dosing pumps, a rapid-mix tank, flow control and pH analyser control loops.”
接著試試Add a downstream clarification tank.Change the pH reagent pump to a duty and standby pair.
這張圖裡有什麼
看懂背後的決策。
01
Use diaphragm dosing pumps for precise chemical injection
02
Control raw water flow with a diaphragm-actuated FC valve
03
Measure pH on the tank outlet and modulate pH reagent dosing via an AIC loop
Reuse for P&IDs of coagulation, flocculation, or chemical dosing systems in water and wastewater treatment where inline pH control and flow-proportional dosing are required.
