Water-vacuum filtration is a method of creating a low to moderate vacuum usually for filtration
or drying. It uses continuous water flow to pull air from a flask creating the vacuum (see photo). Replace vacuum aspirators with vacuum pumps to eliminate water usage and save approximately 238 gallons (900 liters) of water per hour of operation. Consider installing a laboratory vacuum system or utilizing small electric vacuum pumps to generate the required pressure differentials for vacuum applications.
It is crucial to develop a habit of turning off vacuum pumps when they are not in use. Leaving vacuum pumps running continuously can lead to pump failure and excessive water usage for cooling purposes. By practicing proper shutdown procedures and powering off vacuum pumps when not needed, you can extend the lifespan of the equipment and reduce unnecessary water consumption.
Replace with membrane/diaphragm/oil-free pumps
