REVERSE OSMOSIS AND CARBON FILTER WATER PURIFICATION SYSTEM

SERVICES

US Army Engineer Research and Development Center

Environmental Laboratory

1. General. The US Army Engineer Research and Development Center, Environmental Laboratory, Environmental Processes and Engineering Division (EPED) and Ecosystem Evaluation and Engineering Division (EED) have a need for continuous and uninterrupted clean water purified by reverse osmosis technology and carbon filtration for its ongoing research and development activities.

2. Specific Needs for Buildings. Maintain the reverse osmosis system in buildings 6008, 3284, 3297, and 3299, the DI system and UV Bulbs in 5036 Harvey Jones Lab, and maintain the carbon filtration tap water purification systems in bldgs. 5032, 5033, 5037, 5036, 5039, 5044, 5034, 5046, 6000, 6008 FLEES Lab, 6009, and 6017. The RO system, a GE E4-LE 13200 DLX (purchased from Pure Water Solutions, W912HZ-09-P-0129) and carbon filtration purification system need to be inspected monthly and serviced as required to ensure uninterrupted operation.

This need would include any repairs and or parts replacement due to normal wear or other system malfunctions, such as but not limited to, on-site water analysis adjustments to components and repair/replacement of necessary filters, membranes, pumps, deionizers and parts as required for the water system.

Specifications for the RO systems consist of:

- Low-energy design for reduced electrical requirements

- A 1 micron pre-filter

- Automatic inlet shut-off valve

- Permeate and concentrate flow meters

- Thermal motor protection

- Pre-filter, post-filter, primary, and final pressure gauges

Operating Parameters for the RO systems:

- Operating pressure range 100-110 psi

- Maximum recovery rate 75%

- Nominal rejection 95-98%

- Design temperature 77°F (25°C)

- Operating temperature 55-85°F (13-30°C)

- Minimum inlet pressure 30 psi

- Permeate rate 9 gpm

- Motor – 3 phase, TEFC, 208-230/460 VAC

Materials periodically replaced with normal RO system operation:

- Membrane elements Desal AK4040T1305

- Cartridge filter RO, Save, 1 micron,

- Water Softener Sodium Chloride Salt (99% pure or better)

Specifications for the carbon filter water purification system consist of:

- 8” x 44” Tank

- 1.2 Cubic Ft.

- Iodine # Minimum 1000

- Replace every 3 months

Materials periodically replaced with normal carbon filter system operation:

- 8 x 44 Carbon media tanks
