Water Treatment​

Filtering water in aquariums, ponds and fish tanks is vital for creating a safe environment for aquatic creatures to live in. Without proper filtering, chemicals are present that are harmful to aquatic life and the water quality will significantly decrease. Kelin supply activated carbon to manufacturers of aquarium filters.

Soil remediation is required when soil has become contaminated with man-made chemicals. This can happen for several reasons but is often a result of industrial or agricultural activities. If the land is used without being treated first, these contaminants can have dangerous consequences for human health. Activated carbon can remove or reduce the contaminants to safe levels.

Landfill leachate is liquid that has passed through landfill sites. This water tends to contain both suspended matter (matter that is visible to the naked eye) and contaminants that have dissolved into the water. The contaminants within the water depend on the type of landfill: industrial, commercial or mixed. Regardless of what type of contaminants are found in the leachate, it is dangerous to discharge it without treatment to remove or reduce them.

All industries generate wastewaters and typically these wastewaters contain a cocktail of different dissolved contaminants, some that are potentially toxic. The contaminants vary depending on their specific industry or activity. Sometimes this water is recycled back into the manufacturing process, but it is also often returned to the environment into surface water (rivers, lakes or wetlands). Before this can be done it is essential that the toxins and contaminants are removed and the water is made safe for its next purpose.

Municipal wastewater treatment involves using activated carbon to remove micropollutants and impurities from all wastewater produced in towns and cities. This includes leftover water from domestic life (from kitchens, sinks, baths, gardens and toilets) and rainwater from rooftops and pavements. 

As a non-polar adsorbent, activated carbon is the most commonly used material to purify oily wastewater. Compared with other adsorbents, activated carbon has a large specific surface area and a rich microporous structure, so it has good oil absorption and can remove dispersed oil, emulsified oil, dissolved oil and other organic substances in wastewater. This water can contain organic contaminants and man-made chemicals which could have a detrimental effect on the environment and wildlife as well as posing a health risk to humans. Activated carbon can be used to treat the water and make it safe to re-enter the environment again.

People will always need clean and safe water to consume and industries will always need specially treated water for manufacturing. Activated carbon is one of the most effective ways to improve water quality. Its use varies from small scale domestic use, for example in filter jugs, to treating water in municipal plants on a huge scale.

Process water and ultra-pure water are waters that have been treated or purified to meet stringent specifications. These types of water are used in manufacturing across many industries and are not for drinking. Different industries and processes have different specifications and requirements. Kelin’s technical experts can advise on what grade of activated carbon will help you achieve the best results in your specific situation.
