LE-VSS2500 filters achieve reliable performance in wastewater treatment plant operation monitoring and provide rough approximation of organic matter present in solid fractions of activated sludge and industrial wastes. EPA Method 160.2 compliance with Standard Methods 2540C and 2540D compatibility transforms these filters into validated reference-grade media for establishing water quality in suspended solids content. Exceptional versatility extends applications to air pollution monitoring, high-temperature flue gas filtration, and solvent processing environments requiring both thermal stability and analytical accuracy.
