Persistent organic pollutants are a group of organic compounds that have toxic properties, persist in the environment, accumulate in food chains, and found in our drinking water sources.
Industrial and municipal wastewaters can carry a variety of pollutants that can adversely change the ecology of rivers, streams, and lakes that they flow into and so can affect the safety and quality of surface or groundwaters.
Contaminated ground through historical industrial land use, underground storage tanks, or accidental spills may contain non-biodegradable organic chemicals such as PFAS, pesticides, and other harmful contaminants of emerging concern that can have an environmental impact.
Many industrial, manufacturing or waste recycling sites can release VOCs, solvents, or odours such as Hydrogen Sulphide (H2S) into the air from handling, transfer, and process operations.
To have Biogas as an effective source of renewable energy production, it must first be treated to remove contaminants such as siloxanes and hydrogen sulphide (H2S).
The processing of specialty and liquid chemicals often require a purification stage to remove unwanted impurities from the product or off-specification batches.
Gas streams from different applications may contain unwanted contaminants that require removal before their use and activated carbon technology is a very effective technology for removing these contaminants.
Many food or beverage products incorporate a purification step to remove colour contaminants, taste and odour constituents generated in the process or the source water used to create the final product.
Selection of a suitable activated carbon base, with the addition of tailored impregnants, enables Chemviron to customise the activated carbons to meet specific performance requirements and standards.
Activated carbon is recognised as one of the best technologies to recover certain metals such as precious metals from ore, waste, and reclaim streams.
