تصميم متحسس ميكانيكي متعدد التطبيقات في تصفية الماء الملوث

Abstract EN

In this research, a multipurpose mechanical sensor is designed to filter contaminated water.

The study included the study of the effect of salts, soil and microorganisms such as Escherichia coli (E.

Coli) bacteria present in the water sample on the electromagnetic properties.

The electromagnetic signal can be obtained by using a transformer that transmits mechanical waves through a cell containing (pure water, water contaminated with salt, soil and bacteria respectively) and then using receptors that capture the resulting signal.

The study also included the preparation of nanomaterials of silver and carbon in the form of membranes prepared in various ways such as laser and chemical methods and then used as detectors for pollutants and killer of bacteria.

The operating frequency range used in this research ranges from (400 KHz-50 MHz).

Tests in this research included recording the resonant frequency at the first rank of all prepared samples.

The results showed that the highest resonant frequency value was (30 MHz) in the presence of bacteria in the sample and it was observed that the damping factor stabilized in the last three cases of (silver-piezoelectric crystal, carbon-piezoelectric crystal and silver: carbonpiezoelectric crystal).
