ASPEN 5500M DESIGN CRITERIA NSN 4610-01-584-8707 The ASPEN 5500M water purification system will supply 4,000 to 5,000 gallons per day (between 160 to 210 gallons per hour) of highly purified water from virtually any non-saline water source. Water can be drawn from ditches, rivers, lakes or standing water that may contain chemical and/or biological contamination. Dimensions. Both interlocking cases are 43” X 28”X 21”. The approximate dry weight of the water treatment unit is 185 lbs, and the accessory case is approximately 100 lbs.
The Purification Process
General Operation
Two Stage Filtration. The first stage removes sand, dirt and very fine particles down to 5 microns in size. The second stage effectively removes harmful microorganisms such as paramecium, amoeba, giardia, cryptosporidium and other small matter down to 1 micron.
Power Source. Operates on 90 to 260 volts AC at 50 or 60 hertz as well as 10 to 30 volts DC, virtually any power source. The military version comes standard with a 24-volt DC input (optional on the civilian version.) Power cords with military type quick-connects are provided. (Note: A solar option is also available.)
Water Treatment. The replaceable multimedia water treatment canister effectively treats 40,000 to 50,000 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 60,000 gallons. It is most effective when the flow rate does not exceed 3.5 gallons per minute. Disinfecting. An ultraviolet (UV) lamp system is integrated. Rated at 10 gallons per minute, it provides over two times the safety factor required by the 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. Additionally, the level of UV exposure in the Aspen 5500M effectively kills or inactivates minute organisms.
Pressure. The whisper-quiet, variable-speed, self-priming, low-voltage pump can draw water up to 12 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 the volume of water passing through the system from 2.5 to 3.5 gallons per minute, the total run time of the filter canister and the total run time of the UV exposure unit. Safety Features. The operating and monitoring components are designed with a two-stage protective shutdown system. First, the overall system automatically shuts down in the event of a failure in the disinfecting process. Secondly, a valve closes, stopping more water from passing through the system. Replacement Packages. Extended Use Accessory Packages are available and include expendables and spare parts.
