Does anyone know or can reference the seismic code requirements for mechanical equipment. This would involve a new york city wastewater treatment plant where the building is design to withstand seismic loads but what happens to ancillary equipment such as inlet air ductwork for a back up power...
I'm trying to develop the control strategy for a booster pumping sytem. There are 4 booster pumps three operating and one standby, each pump operates at 130 TDH at 3500 gpm. the maximum flow rate for the system would be 10500 gpm. The pumps are controled by a variable frequency drives. The...
I would like to develop a booster pump system that would maintain a system pressure of 60 psi at a municipal plant. The system will distribute effluent water at various locations. My suction header is drawing off of an effluent channel. A positive suction head of 14 feet plus atmospheric. I want...
What is typically installed on fiberglass storage tanks to prevent surges in backpressure during chemical tank loading using air loading practices for tanker trucks. These trucks utilize compressed air to transfer liquid volume from tanker to storage vessels. The fiberglass storage tanks are...
I need information on putting together a booster pump system utilizing effluent water for a municipal plant. Initially the minimum demand is about 3300 gpm. The final maximum demands are about 12000 GPM. The system needs to supply effluent water at a pressure of 60 psi. The total number of pumps...
Typically chemical bulk storage deliveries on a tanker truck use air to unload the contents of about 5000 gallons. The tanker trucks utilize a compressor which pressurizes the tank to 20 to 30 psi. The compressor puts out about 15 cfm. Once the tanker truck is toward the end of the unloading its...
