Adsorption

 

For which applications?

Adsorption is an interesting technique to remove pollutants from both liquid and gas waste streams.

Suitable applications are: API removal, off-gas purification, selective removal of a specific pollutant, polishing to ensure discharge limit,...

 

How does it work?

Adsorption is a multiple phase (liquid-solid or gas-solid) separation technique in which organic and/or inorganic components are retained by a solid component: the adsorbent. Pollutants are adhered to its surface and removed from the waste stream using interactions with the adsorbent’ surface. In general, two types of adsorption are identified, bases on this interaction mechanism: (i) physisorption (i.e. through physical bonding) and (ii) chemisorption (i.e. through chemical reaction). The lifespan of the adsorbent materials can be significantly extended by regeneration, in this process the adsorbent’ surface is cleaned and reactivated.

Depending on the application, a choice can be made for a selective (e.g. zeolites) or a non-selective adsorbent (e.g. activated carbon). The first option is preferred when only a specific target molecule has to be removed, e.g. API removal. The latter is often chosen in case of a fail-safe, to ensure the removal efficiency, e.g. for polishing of a treated waste stream.

 

How can InOpSys Help?

Based upon our profound background and many years of academic research we can screen and determine the right adsorption treatment. In our lab we can execute lab testing and if required we can provide pilot scale units. Finally we design, construct and operate a full flexible, modular and mobile (ATEX certified) unit, to treat on-site your wastewaters.
