Systems
EWR provides solar-powered water filtration systems that incorporate clean water technology and water purification chemistry. Our systems feature 7 levels of filtration to ensure the removal of potentially harmful sediments, heavy metals, chemicals, bacteria, cysts, giardia and cryptosporidium. The systems can also be powered by AC or DC power.

EWR solar-powered water filtration systems provide 25,000 gallons of drinking water per day (GPD) at $.00015 per gallon; can be deployed anywhere in the world in 48 hours; and can be operated with little training and virtually no maintenance in off-grid or on-grid situations around the world. |

Overall System Specifications
The system is designed to pump and purify water at a maximum rate of 25 gallons per minute. The unit will handle source water wells, bore holes, lakes, ponds, rivers, streams, agricultural ponds and catch basins. Existing water mains where water is not potable can also be piped in and out of the system for purification. All filter media and hardware are of
Environmental Protection Agency (EPA) and National Science Foundation (NSF) approved products and meet or surpass EPA or
World Health Organization (WHO) standards for potable water. The unit removes most industrial pollutants, such as heavy metals and arsenic. All operations, metering and sampling aspects can be controlled via a multi-language and language-neutral control. The unit’s dimensional footprint is 1.2m W x 2.5m L x 1.2m H. The unit is built to metric measurement standards (USA and UK Standard built units are also available on request).
Customized Specifications
Conditions of water vary as greatly as topographical conditions do on the surface of the planet. This unit is designed to handle 97% of water encountered in compromised locations, such as
in relief areas and camps, combat areas and disaster zones. In addition, the unit can be adjusted for water conditions that may be unusually
"off the scale." Examples of such conditions may include industrial contamination, highly atypical pH levels, high ferric iron concentration, high lime and calcium content. As an option, customized units can be engineered to handle unique field / platform / delivery needs and water conditions.

Summary:
EWR provides a water filtration unit that has been designed to be deployed in the worst conditions in the world. We have engineered a mobile water treatment unit
from the "trenches" in a no-nonsense construction manner. This unit is the ultimate in field  friendliness and toughness. All filters are
self-cleaning and need no periodic renewals, all parts are ruggedized for true field use, power can be obtained under all field conditions, and if repairs are needed, they can be carried out with tools from local stores or street markets. Design is aimed at heavy duty low-tech hardware. In short, this unit will produce potable water longer and better than any other mobile unit in the world.

To perform a backflush:
- Turn the backflush valve handle 180 degrees to
reverse the flow of water. (Located at the top of the Intake pipeline)
To change the antibacterial / antiviral filters:
1. Loosen the eyelets (3 each) from the top of the antibacterial tanks.
2. Open the lid.
3. Remove the rubber seal. If seal is damaged,
dispose of it and replace it with a new one.
4. Remove the pressure plate.
5. Remove and dispose of the filters, or clean/exchange.
6. Seat new filters.
7. Clean and replace the pressure plate.
8. Clean and replace the rubber seal.
9. Close lid and tighten eyelets.
