Design Specifications
GravityPure UF Dimensions: Assembled: 101 cm x 77 cm x 149 cm, 51 kg Typical assembly time: 2 hours Overview: Interview with representative Core treatment is ultrafiltration: 0.02-micon pores for removal of bacteria, viruses, and other waterborne diseases Process is low-waste, with typically >90% net water recovery Integrated bottle washing station for sanitizing inside of bottles Water Supply: Any fresh water supply (not salt water) Must be tested for chemical contamination Should be stored in an elevated holding tank. Power Supply: Must pump or manually feed water to at least 2 meters.

Replacement Components
Extensive package of spare parts is included with each unit. Additional parts are available from Healing Waters, although many are locally available in urban areas. Interview with representative
Lifecycle
The manufacturer provides a 1 year warrenty. Disposal is a mixture of non-hazardous waste and recyclable components (eg stainless steel frame). The most significant replacement cost is the Ultrafiltration Membrane. Typical membrane life is 2-5 years, with a $300 replacement cost. Interview with representative
Manufacturer Specified Performance Parameters
GravityPure UF can achieve a production rate from 500 to 10,000 liters per day depending on water pressure and number of parallel Ultrafiltration membranes.
Vetted Performance Status
Unknown
Safety
No hazards noted.
Complementary Technical Systems
In some cases there may be a need for large water storage tank(s), sand pre-filtration, or activated carbon post-filtration. The Healing Waters Engineering Team will work with the users to make sure that they have the right solution for their context. Interview with representative
