Title: METHOD AND DEVICE FOR ONLINE MONITORING OF WATER QUALITY
Abstract:
A method for monitoring quality of a water flow in a pipe, by diverting a flow into a laser particle counter to count particles within a particle size interval in the water, to continuously determine the number of particles within the size interval, comparing the count with a reference value and taking a sample of the water from the pipe when the count exceeds a threshold value, and also diverting a flow of water from the pipe into a unit that separates the flow into fractions, and taking a sample of at least one of said fractions when the count exceeds a threshold value,and also sending an alarm signal when the count exceeds a threshold value. When the count exceeds at threshold value, the water is treated with ozone.
