Water and Wastewater
Industries Served - Particle Technology Labs
Regulatory agencies use particle size and concentration analysis values to determine compliance with water quality standards. For example, the water quality industry uses particle characterization results to evaluate filtration systems and adhere to wastewater regulation effluent standards. City municipalities use particle size and concentration to ensure safe drinking water and water quality of industry discharge. Process water engineers use particle size and concentration data when designing water filtration systems.
While other techniques are used depending on the project goal, Single Particle Optical Sensing (SPOS) / Light Obscuration, Electric Sensing Zone and Nanoparticle Tracking Analysis (for particles less than 0.5 µm) are the most widely used. These techniques are particle counters and thus can provide high resolution distributions on both a volume and number basis as they measure individual particles in the sample. The increased resolution of a particle counting technique can offer many advantages over other groups of particle sizing techniques when it comes to the design and monitoring of filtration and treatment systems.
