The monitoring of air and water in the environment is of utmost importance in today’s day and age. The wastewater and solid wastes released from industries also need to be checked for residues and chemicals before they are discharged. Borosil filter media is manufactured in such a way that they are neutral, metallic ion free, and stable enough for a contaminant-free sampling of air, water, and wastewater.

BOROSIL filter papers can be confidently used in areas that are subject to strict official requirements like the DIN, EPA, ASTM, etc.

Target applications include :

  • Ambient air monitoring
  • Determination of suspended particles and total suspended particles in the air.
  • Monitoring the presence of pollutants in the air at different measuring points.
  • Monitoring of anthropogenic atmospheric emissions (oil refineries, power stations, burning of liquid and solid fuels, cement factories, mining industries, incinerators, iron foundries, grinderies, asphalt plants, glassmakers, ceramic factories) and at stationary sources.
  • Measurement of dust release in workplace and production processes, exhaust fumes from private houses, and newly developed engines (for cars and other vehicles).
  • Gravimetric analysis of organic and inorganic contaminants in water and wastewater.
  • Monitoring the microbiological quality of drinking water.
  • Determination of total dry residue in water.
  • Determination of dissolved organic carbon (DOC) and total organic carbon (TOC) in water.
  • Analysis of waste products in the disposal of industrial waste and laboratory waste

Used in the analysis of:

  • Air pollution
  • Emission control
  • Water
  • Waste products
