Environmental Testing Services

Particle size, particle concentration and other physical characterization analyses are critical to many environmental applications.

clean-and-dirty-water-samples-in-hands Regulatory agencies in the environmental sphere demand strict compliance to standards and discharge regulations. Physical testing of samples for parameters such as particle size and concentration can give insight to the process control engineer on how effective and compliant a discharge handling system is operating. Particulate loading from both air emissions and waste water discharge are monitored in many industry sectors and PTL testing provides valuable supporting data in this monitoring process.

Evaluation of filter efficiency by analysis of pre- and post-filtration samples for particle size and concentration has proven useful to numerous clients. Values such as PM10, PM2.5, total suspended solids concentration, pH, conductivity and particle size distribution are just some of the commonly referenced values by regulatory agencies and process engineers. PTL has provided accurate and reliable testing for these parameters since its inception.

Common Samples: Soils / Sediments, Process / Cooling Water, Stack Testing / Emissions, Dust, Filter Solids, Effluents

Analytical Testing: Particle Size Distribution, Image Analysis, Total Suspended Solids, Zeta Potential, Sieving, SEM, pH, Conductivity, True Density
