Reliable and continuous measurements of Oil in Water.
Measurement of Oil in Water with Fluorescence
Fluorescence is a widely used principle for measuring oil in water. It relies on the fluorescence properties of certain hydrocarbons, which emit light at a specific wavelength when excited by an external light source.
In a fluorescence-based oil-in-water monitor, water samples are passed through a sensor that exposes the sample to a light source. The emitted fluorescence is then detected by a sensor, which measures the intensity of the fluorescence and calculates the concentration of oil in the water sample.
Fluorescence-based oil-in-water monitors are known for their high sensitivity, and can detect low levels of oil in water. They can also discriminate between different types of oil, and can be used to measure a wide range of hydrocarbons including crude oil, diesel, and lubricating oils. Additionally, these monitors can be used in both fresh and saltwater environments and are relatively low maintenance.

Measurement of Turbidity
Turbidity and Total Suspended Solids (TSS) are both measures of the amount of solid particles suspended in a liquid. Turbidity is a measure of the cloudiness or haziness of a liquid caused by the presence of suspended particles, while TSS is a measure of the total weight or volume of suspended solids in a liquid.
Both turbidity and TSS measurements are widely used in water quality monitoring and treatment, as high levels of these parameters can indicate the presence of pollutants or other contaminants in the water.
TSS and Turbidity measurements can be used to monitor the effectiveness of water treatment processes, such as sedimentation and filtration, and to detect changes in water quality that may indicate the presence of pollutants or other contaminants.
Ultrasound Self-Cleaning
Ultrasound self-cleaning is a method for cleaning surfaces using high frequency sound waves. It is based on the principle that sound waves can create microscopic bubbles in a liquid, which then implode and generate high-energy shockwaves. These shockwaves can remove dirt, grime, and other contaminants from surfaces, without the need for chemical cleaners or manual scrubbing.
Ultrasound self-cleaning systems typically consist of an ultrasonic generator, which creates the high-frequency sound waves, and a transducer, which converts the electrical energy from the generator into mechanical energy in the form of sound waves. These waves are then directed towards the surface to be cleaned, typically through a cleaning solution.
The advantages of using ultrasound self-cleaning include that it is efficient, fast, and can reach difficult-to-clean areas. It is also environmentally friendly and does not use harsh chemicals.
