Assault Amphibious Schools Camp Pendleton 20 Bay Wash Rack

The wash rack recycling system that previously existed at Assault Amphibious Schools on Camp Pendleton did not supply adequate pressure for wash operations, was often inoperable, and caused a variety of environmental issues. ESI was asked by Base Environmental to work with the staff of Assault Amphibious Schools on Camp Pendleton, and Base Environmental and Contracting Departments to design and engineer a new system to provide for maximum uptime and maximum simultaneous usage.

ESI was contracted to have nine stations running concurrently, but was able to design and engineer a system that allows for the simultaneous operation of multiple wash stations at 3000psi and of all 20 stations at 1500psi.

During installation, ESI used as much existing wash rack infrastructure as possible, including the conversion of an existing sump into a in-ground oil water separator as the first phase of water cleaning, and provided new recycling and water distribution systems. The new recycling system consists of industrial-rated components to serve the high usage needs of the Marines. An 800-gallon clean water storage tank ensures that recycled water is always available for wash operations. ESI installed a dual pump system, which automatically activates a second pump when multiple stations are in use. This makes certain that the pressure at each station is acceptable for AAV washing needs. The entire system was designed specifically to fit into an existing mechanical room.

Unique to ESI wash rack recycling systems is Remote Monitoring Telemetry. All functions of the system from water usage, to tank levels, to temperature is monitored 24/7 via the Internet. If any parameter is outside of normal operating range, ESI technicians receive an immediate email and can oftentimes repair the function via the Internet. This feature saves AAS service calls and, more importantly, it saves downtime of the wash rack. Other functions monitored by the Remote Monitoring are pH, system air pressure, collected oil levels, vessel pressure and flow rates, backwash cycles, CPU status, and cellular signal status. The Remote Monitoring data is logged in 15-second increments and can be used for graphing and trending. This is very helpful to the Unit in their environmental reporting and to view the wash rack system usage.

Other components in the recycling system are the AnJan OWS for the separation of oils from the wash effluent and the AnJan Paper Filtration system to remove larger sediment particles. This system is also engineered with two AnJan Gigasorbers which remove odor, color, TDS,TSS, BOD, COD, and other contaminants. The Gigasorbers, along with disk filtration, are the final stage in providing the wash rack with clean, odorless recycled water for wash operations.
