Design Specifications

The SolarPure UF uses a 5-step water treatment process which is low-waste, with typically >90% net water recovery. It includes:

• Pre-filtration: 105-micron stainless steel screen.
• Ultrafiltration: 0.02-micon pores for removal of bacteria, viruses, and other waterborne diseases.
• Activated Carbon: 24kg of coconut-shell carbon contains 28,000,000 m2 of surface area. Effective at reducing taste and odor issues.
• Polishing Filter: 0.35-micron cartridge filter.
• Chloramine (at 1.0 ppm) is injected into the final water as a preservative.

Replacement Components

Inventory of replacement components are stocked in several countries around the world and growing. ^{Interview with representative}

Lifecycle

The manufacturers offer a 1 year warrenty. Typical life cycle of 10-20 years, but could be much longer with proper maintenance. Equipment frame and most plumbing/valves are stainless steel. Regarding disposal, filtration media is non-hazardous, stainless steel is a recyclable commodity, and electronic components should be properly recycled. ^{Interview with representative}

Manufacturer Specified Performance Parameters

Provides ultrafiltration with removal of bacteria, viruses, and other waterborne diseases. The SolarPure UF can reach a production rate of up to 30 liters per minute at 400 W, and can filter water with as little as 50 W. All built-in functionality is fully functional at 200 W. ^{Interview with representative}

Vetted Performance Status

During design phase, 3rd-party performance testing performed by Dr. Nathan Hancock, Colorado School of Mines. ^{Interview with representative}

Safety

The filtration media is non-hazardous.^{Interview with representative}

Complementary Technical Systems

For surface water, sand pre-filtration is recommended. ^{Interview with representative}
