Pinoy students develop ultrasonic washing machine
For centuries, washing laundry has always required a "particular" cleaning agent —from ashes and silicates of the Egyptians to your mom’s choice of detergent— to go with water.
But a group of young Filipino engineering students thought otherwise. Their solution: ultrasonic cleaning method.
Keith Michael Basa, Kristina Paula Gomez, Alvin Quinio and Ferdinand Navarro-Tantoco, graduating electronics and communication engineering students of De La Salle University (DLSU) Manila created a prototype that could be used to ease home laundry duties without harmful effects to the environment.
In their study, “Prototyping of an ultrasonic test machine for washing fabrics”, they designed a prototype of an ultrasonic washing machine and tried to clean several types of fabric with different kinds of stains from animal blood, to coffee and ketchup.
And they succeeded.
