Title:
METHOD AND DEVICE FOR THE MEASUREMENT AND IDENTIFICATION OF BIOFILMS AND OTHER DEPOSITS USING VIBRATION
Document Type and Number:
WIPO Patent Application WO2007029143
Kind Code:
B1
Abstract:
The present invention concerns a method and device to monitor the formation and removal of biofilms and other deposits in ducts, reservoirs and equipments, using vibration. The afore mentioned device is composed by an element that generates vibration (1) and an element that senses vibration (2), fixed on the external surface of a duct, reservoir or equipment (3). An electrical signal is generated by an electronic data acquisition unit (4) connected to the element that generates the vibration (1). The duct, reservoir or equipment (3) vibration leads to a signal in the vibration sensing element (2) which is measured and processed by the electronic data acquisition unit (4). The present invention is able to monitor the formation of deposits on surfaces and it can be applied, for example, to fluid distribution systems and fluid heating/cooling systems.
