Method of treatment analysis with particle imaging
A method for determining the effectiveness of the treatment of a fluid for the purpose of reducing or eliminating particles in the fluid. The method includes the steps of obtaining samples of the fluid before and after treatment, delivering the samples to a particle imaging system, obtaining image information of particles in the samples, including particle colors, and comparing the difference in particle color from the first sample to the second sample. A change in particle color detected is indicative of particle death.
1. A method for determining the effectiveness of a fluid treatment process, the method comprising the steps of:
a. acquiring a first sample of a fluid to be treated prior to treatment;
b. analyzing the first sample with particle imaging for particles in the first sample, including obtaining color images of the particles in the first sample;
c. acquiring a second sample of the fluid after the fluid has been treated;
d. analyzing the second sample with particle imaging for particles in the second sample, including obtaining color images of the particles in the second sample;
e. defining a particle image color indicative of particle death; and
f. comparing the color images of the particles in the first sample with the color images of the particles in the second sample to determine a change in particle image color corresponding to the defined particle image color.
2. The method of claim 1 wherein the defined particle image color is blue and an increase in the color blue in the color images of the particles in the second sample indicates that the treatment has produced the death of particles in the fluid.
3. The method of claim 1 further comprising the step of repeating steps d and f X more times, wherein X≧1.
4. The method of claim 1 wherein the fluid is ballast water.
5. A system for determining the effectiveness of a fluid treatment process, the system comprising:
a. a particle imaging system configured to:
i. acquire a first sample of a fluid to be treated prior to treatment;
ii. acquire a second sample of the fluid after the fluid has been treated;
iii. analyze the first sample for particles, including obtaining color images of the particles in the first sample; and
iv. analyze the second sample for particles, including obtaining color images of the particles in the second sample; and
b. a computing device including information defining a particle image color indicative of particle death, wherein the computing device is configured to compare color images of the particles in the first sample with the color images of the particles in the second sample and determine a change in particle image color corresponding to the defined particle image color.
