The ASPEN 5500M water purification system will supply 18.000 liters per day (around 750 liters 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.

Description

NSN 4610-01-584-8707 

The ASPEN 5500M water purification system will supply 18.000 liters per day (around 750 liters 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.

The Purification Process
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.

Water Treatment
The replaceable multi-media water treatment canister effectively treats 150.000 to 190.000 liters 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 225.000 liters. It is most effective when the flow rate does not exceed 12.5 liter per minute.

Disinfecting
An ultraviolet (UV) lamp system is integrated. Rated at 10 gallons per minute, it provides as much as three 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 inactivates minute organisms.

General Operation

Power Source
Operates on 90 to 260 volts AC at 50 or 60 hertz as well as 10 to 30 volts DC, virtually any one phase 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).

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 the volume of water passing through the system from 7.5 to 11 liter 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.

Dimensions
Both interlocking cases are 43” X 28”X 21”. The approximate dry weight of the water treatment unit is 199 lbs, and the Extended Use is approximately 100 lbs.
