Particle Counting Techniques

Particle counting involves measuring the concentration and size distribution of particles suspended in water. The two primary techniques employed are:

• Light Obscuration Particle Counting (LOPC): Utilizes a laser to illuminate particles, and the resulting light scatter is measured to determine particle size.
• Coulter Principle Particle Counting: Employs an electrical current to differentiate between particles based on their resistance.

Applications in Drinking Water Treatment

Particle counting finds numerous applications in drinking water treatment plants:

• Raw Water Monitoring: Assessing the particle load in raw water sources to determine appropriate treatment requirements.
• Coagulation and Flocculation Monitoring: Evaluating the effectiveness of coagulation and flocculation processes in removing particles.

li>Filtration Monitoring: Assessing the performance of filters in capturing particles and ensuring water quality.

• Disinfection Monitoring: Determining the impact of disinfection on particle concentration and microbial removal.

ISO 12196: A Global Standard

The International Organization for Standardization (ISO) has established ISO 12196 as the international standard for particle counting in water. This standard specifies the requirements for equipment, procedures, and reporting of particle counting results. Adhering to ISO 12196 ensures accuracy and consistency in particle counting measurements across the water treatment industry.

Industry Best Practices

Implementing the following best practices can enhance the accuracy and reliability of particle counting in drinking water treatment:

• Proper Equipment Calibration: Regular calibration of particle counters using certified reference particles is crucial.
• Representative Sampling: Ensuring that the water sample analyzed is representative of the water being treated.
• Data Handling and Interpretation: Understanding the significance of particle size distribution and interpreting the data in the context of water quality.
• Continuous Monitoring: Implementing online particle counters for real-time monitoring and early detection of water quality fluctuations.

Particle counting is an indispensable tool in the field of drinking water treatment. By understanding the techniques, applications, and industry best practices outlined in this article, water treatment professionals can effectively monitor and control particle levels, ensuring the delivery of safe and high-quality drinking water to consumers.
