| Closed-Loop Washrack |
Equipment Description
The typical closed-loop system consists of above ground oil/water separators, coalescers, filters (oil/water, polishing, ultrafiltration (molecular, multimedia carbon, etc.), pumps, piping, and motors. Sites with fewer requirements may require only upgraded oil/water separators. The washrack contains and treats wastewater generated from the washing of aircraft, construction equipment, or vehicles before it is discharged. Wastewater typically contains detergents, fuel, oils, metals, and other contaminants.
Benefits of Use
Decreases need for utility water for closed-loop systems. Decreases need to procure new detergent for closed-loop systems. Saves costs because of zero discharge of wastewater for closed-loop systems. The specific equipment will vary by site application, but typical applications are: upgrading inadequate oil/water separators that discharge wastewater to Publicly Owned Treatment Works (POTWs), replacing existing washrack equipment with closed-loop systems to recycle wash water, minimizing the need for utility water and detergents, and eliminating the requirement for water discharge permits.
