Sorbents are insoluble materials or mixtures of materials used to recover liquids through the mechanism of absorption, or adsorption, or both. Absorbents are materials that pick up and retain liquid distributed throughout its molecular structure causing the solid to swell. The absorbent must be at least 70 percent insoluble in excess fluid. Adsorbents are insoluble materials that are coated by a liquid on its surface, including pores and capillaries, without the solid swelling more than 50 percent in excess liquid. To be useful in combating oil spills, sorbents need to be both oleophilic (oil-attracting) and hydrophobic (water-repellent).

Sorting Tray Conveyor System is used for sorting small articles. It has sorting vessels disposed in a plurality of rows crossing and a timing basket table. The timing basket table receives articles from the take-in conveyor and discharges the articles to the sorting conveyor.

Sound Attenuated Pump is designed to prevent vandalism/theft. Sound attenuated pump has high quality ductile or cast iron volute with semi-open impeller that allows passage of large size solids. It has large fuel tanks for 24 hour operation. It operates quietly in various conditions. Its size varies from 6″-8″. It has ability to move large volumes of liquid. The noise level of sound attenuated pumps is as low as 67dba at 23'. This pump has ability to adjust to varying flows.
