Reliable data is critical in assessing air pollution. Many filters that can collect polluting material are available, but they differ in properties that affect the measurement validity.
Filtration in wastewater and drinking water testing
Suspended solids testing is an important part of determining the quality of drinking water and effluent from industrial plants or from domestic sewage. Filtration removes insoluble particles from liquid samples and retains particles for suspended solids analysis.
Soil testing requires that chemical compounds be extracted from their matrix using pH and heat modulation and, finally, concentrated. Filtration plays a key role throughout the soil testing process. Quality is essential to maintain the integrity of results.
