Because of their high selectivity, zeolite catalysts are often the most efficient and cost-effective method for a number of refinery conversions, particularly in upgrading refinery streams into high-octane gasoline blending stock. The properties of zeolites uniquely suit them for tailoring to specific applications. Visit the Zeolyst International website or be in touch with a Zeolyst sales representative to learn more.
The unique properties and selectivity of zeolites can provide effective solutions for environmental pollution by minimizing the production of pollutants and by secondary treatment of the effluents produced. Many of the gains made by the current generation of environmental technologies are being offset by the growth of industrialized populations. Consequently, new and creative pollution prevention and abatement methods are under investigation.

I Accept Show Purposes. Get Best Quote. Yes, I am interested! The main difference is that it is lighter and therefore can be backwashed more easily and has a higher service flow rate. Filter sand size, angularity and hardness are the important filter sand characteristics to ensure proper filtering.
Furthermore these coconut shell activated carbons particularly attractive for water and critical air applications as well as point-of-use water filters and respirators.
It is an insoluble matrix or support structure normally in the form of small 0. The beads are typically porous, providing a large surface area on and inside them. The trapping of ions occurs along with the accompanying release of other ions, and thus the process is called ion exchange. There are multiple types of ion-exchange resin. Most commercial resins are made of polystyrene sulfonate. Ion-exchange resins are widely used in different separation, purification, and decontamination processes.
The most common examples are water softening and water purification. In many cases ion-exchange resins were introduced in such processes as a more flexible alternative to the use of natural or artificial zeolites.
