ASPEN 1800BC DESIGN CRITERIA The ASPEN 1800 Brief Case and/or Backpack water purification systems will supply up to 1,800 gallons per day (75 gallons per hour) of highly purified water from virtually any non-saline water source. Water can be drawn from ditches, ponds, rivers, lakes or standing water that may contain chemical and biological contamination. The Purification Process Two Stage Filtration. The first stage removes dirt and large particles through an external screen. The second stage removes harmful microorganisms such as paramecium, amoeba, giardia, cryptosporidium and other small matter down to 1 micron in size. Water Treatment. The replaceable multi-media water canister effectively treats 7,500 gallons of surface water containing contaminants such as lead, barium, selenium and arsenic prior to replacement. It also removes high levels of manmade pollutants such as solvents, insecticides and petrochemicals. When used to eliminate possible microbial contamination in clear water, the canister may be used for up to 9,000 gallons. The 1800 is most effective when the flow rate does not exceed 1.25 gallons per minute. This unit has a self-monitoring flow system that governs its own flow rate. Disinfecting. The ruggedized ultraviolet (UV) exposure system is rated significantly higher than required by US regulatory agencies and exceeds the World Health Organization’s standards for total disinfection. UV is much faster acting than chlorine and has been found to destroy 99.99% of all bacteria and viruses found in water, such as e-coli, cholera, typhoid, anthrax and polio. General Operation Power Source. Operates on 90 to 260 volts AC at 50 or 60 hertz, virtually any international power source, and from a 24 volt DC Military connector. The 1800 comes standard with 2 unrestricted batteries that can be recharged from AC or DC power sources as well as sunlignt from an optional solar package. Pressure. The whisper-quiet, variable-speed, self-priming, low-voltage pump can draw water up to 10 feet and provides water on demand at pressures between 22 and 45 pounds per square inch (PSI). This is highly desirable when filling containers or pumping through a manifold. Using quick connects and knobs, no wiring or tools are required to change the pump. Triple Mode Display. A digital display shows; water volume passing through the system, the total run time of the filter canister, and the UV exposure unit. Safety Features. The monitoring components are designed with a two-stage protective shutdown circuit. The system will automatically shuts down in the event of a failure in the disinfecting process. In addition, the pump stops and a valve will close, stopping any more water from passing through the system. Post Treatment. Water to be stored should be treated with sodium hypochloride (chlorine) or hydrogen peroxide. (Both are easy to use.) Dimensions. The BC unit is 24” X 20” X 14” and weighs 68lbs. The BP unit is 21” X 18” X 10” and the approximate dry weight is just over 50lbs. Accessory packages are available for either unit.
