Adsorbents. In many "fluid" streams, conceptually in gas or liquid phase, or specifically potable water or household air, there are frequently small quantities of contaminants. These may be in the parts per million or even billion range, but they affect the desirability or usability of that fluid stream.
- The nitrates, chloramines, and lead must be removed at the point-of-use for drinking water.
- The dissolved metals and sulfites must be removed from the supply water.
- The pet odors must be removed from the air.
- The offending taste must be removed from the water.
- The silver must be recovered from the processing fluid stream.
- The varied contaminants must be captured from the ground water.
In many cases, the applicable technologies are created surface effects, where contaminants become bound onto and into proprietary additives, and removed from the fluid stream. Of course, the contaminants need to be retained successfully; such as applications satisfying landfill disposal requirements. Or the contaminants must be reliably extracted over many gallons, such as NSF Standard 53 contaminant claims.
We provide proprietary additives to you in functional form with the experience to cost efficiently incorporate them into your material or product so that the contaminants are reduced or removed. We can help you with the analysis of the achieved performance, and the marketing claims you gain.
Surfatas sells adsorbents for dissolved metals, e.g. lead from potable water or odors from air. These come in various size particles for different formats – very fine (e.g. 4 microns) to granular (e.g. 20x50 mesh) for column applications.
Adsorbent Technical
Surfatas proprietary adsorbent technologies function in one or a combination of ways. The most familiar mode of action in water based situations with dissolved contaminate adsorption is an ion exchange process, specifically targeting dissolved heavier metals and exchanging a sodium ion. This process is optimized by proprietary formulas, crystal structure, and particle design. The metal is subsequently tightly bound to the particle. Under specific conditions, the material may be regenerated.
In gas (air) phase applications, the materials leverage unique surface activity, pore size, and polarity to attract contaminants. Typically this is a contact time/frequency solution
We have several products in various particle sizes for bed, column, and compressed media applications.
