Solar Powered Mobile Water Filtration Unit FAQ's 

  1.  What is the primary differentiation between GPRM’s water filtration systems and other systems currently available on the market? GPRM uses only the highest quality materials and components, which means our system is low maintenance, rugged and easy to maintain in the field; our system solution optimizes power captured by the solar panels to deliver more water with less sunlight; our system can be operated with little training, and setup time at a location can be less than one hour.
     
  2. Why is the GPRM system considered to be a "green" solution with low environmental impact? The primary source of power is renewable solar energy. There are no harmful or hazardous chemicals used in the filtration process. When the adsorption media has been exhausted and needs to be changed, the spent adsorption media is safe enough to discharge in a regular landfill without special handling.
     
  3. Does the GPRM system have a low carbon-foot print when compared to other solutions? Our robust system eliminates the need for constant shipments and deliveries of consumable cartridge filters every few weeks, this eliminates the need to manufacture, pack, ship, drive, and burn hydrocarbons to deliver those never ending supplies. All of those exhausted cartridge filters need to be disposed of as well. The least amount of waste involved in any product is a good thing and also good for the earth. GPRM’s design is so well engineered that it does not require home system based disposable cartridge filters. Our extensive experience in the field has helped us understand the water purification needs in the world’s most remote and harshest environments. In times of an international crisis a frequent solution to a clean water shortage is to air freight thousands of gallons of bottled water to affected areas. The estimated fully burdened costs exceed $400,000 per planeload and this does not include the significant carbon footprint generated to load a C17 cargo plane with bottled water, pay for the pilot, loadmaster, crew, and fuel, on your way to your destination with a maximum of 19,161 gallons of water on board. The amount of trash from all of those consumed plastic bottles cannot be ignored either. One of our systems on the ground in that very same location can generate much more than 25,000 gallons of fresh drinking water EVERY DAY with no need for constant C17 plane trips or massive piles of plastic bottles littering the landscape.
     
  4. What are the pumping and purification capabilities of the GPRM mobile solar powered water filtration system units? The units are engineered and capable of safely producing up to 50,000 gallons per day of fresh drinking with any combination of solar, generator, or existing municipal water pressure.
     
  5. Which types of pollutants does the GPRM mobile solar powered water filtration system filter? The unit is capable of producing drinking water free of physical and bacteriological contaminations. The unit will not take care of industrial contamination, such as hydrocarbons, chemical waste, etc.
     
  6. What maintenance is necessary for optimal operation of the GPRM mobile solar powered water filtration system? The user can monitor the pressure gauges on the unit to determine if any backwashing may be required, UV lamps should be replaced yearly. The solar panels should be kept as clean as possible.
     
  7. What are typical annual maintenance costs? UV lamps should be replaced yearly and adsorption media every 3-5 years (or longer. Amortized over a yearly basis is less than 1% of system cost.
     
  8. How often do filters have to be changed? The adsorption media is long lasting and can be backwashed to remove particulates when necessary. Depending upon the water quality the adsorption media can last from 3-5 years (or longer) before needing to be replaced. The bacteriological filter cartridges can be easily cleaned in the field by pressure steam cleaning or cleaning with a chlorine solution.
     
  9. How is the mobile water filtration system transported from location to location? Both units are forklift ready, both units have helicopter lift points, and the mobile unit can be placed on a trailer or truck bed for easy transport.
     
  10. What are the weight and dimensions of the GPRM mobile solar powered water filtration system in the shipping mode and in the operational mode? Our skid-mounted mobile unit weighs 2,250 lbs and is 8'L x 4'W x 6'H, (2.5m x 1.2m x 1.8m). The Tricon container unit weighs 5,200lbs and is housed in a secure and self contained 8'L x 6.5'W x 8'H (2.5m x 1.2m x 2.5m) shipping container.
     
  11. What pre-deployment site preparation is required prior to operating the GPRM mobile solar powered water filtration system? Site preparation is simple. All the system requires is a level area to place the unit that has good site lines to the sun as it travels thru the sky during the day, and a water source within 60' (30m) nearby.
     
  12. Is there a battery system in the GPRM mobile solar powered water filtration system? The filtration unit uses one 12 volt, maintenance free, sealed gel battery.
     
  13. How long will the battery last?  The battery is only used to power the UV filtration lights. Battery life will depend on many factors but a typical battery will last around 5 years if properly charged and cared for.
     
  14. Does the solar array have to be constantly angled toward the sun? For locations north of the equator the solar panels should be angled towards the south, for location south of the equator the solar panels should be angled towards the north. No solar tracking devices are necessary. GPRM recommends that manually adjusting the panels is the most practical method for sun tracking when in the field.
     
  15. Does the end user need to purchase anything else in order to make the GPRM mobile solar powered water filtration system operational? No, the unit comes with everything needed to begin operating immediately. A small toolkit, spare UV bulbs, and misc spare parts are shipped with each unit.
     
  16. What is the difference between the GPRM solution and reverse osmosis (RO) and ultra violet (UV) purification? The GPRM solution purifies 100% of the water it processes and does not use a reverse osmosis technique which produces troublesome amounts of waste water and waste solids in the treatment process. As an extra layer of redundancy the GPRM solution uses UV light as another disinfecting method to remove harmful bacteria or pathogens in the water.
     
  17. Do I have to be concerned about salts, PPM, and TDS only when purifying water near the ocean? Some areas may have a higher than normal amount of brackish or salt water in the water supply. The GPRM water filtration units are designed to purify non-fresh water and are not recommended for brackish or salt water purification. We can custom design a brackish or sea water purification system depending on the TDS (total dissolved solids) PPM (parts per million) chemistry of your water supply. Contact us for more details on these customized purification systems.
     
  18. What are the various types of filters the GPRM mobile solar powered water filtration system uses? Non-hazardous adsorption media and bacteriological filters.
     
  19. What safety features does the GPRM mobile solar powered water filtration system design incorporate? Our system is designed to operate in the harshest conditions but care should be taken when deploying the solar panels under the most severe high wind conditions.
     
  20. Are there any environmental conditions that would prohibit operation of the GPRM system? Extremely windy conditions may require the stowing of the solar panels but if you had an alternated energy source such as a generator you could still produce clean water. All electronics are in housed within NEMA enclosures to protect against excessive moisture. The solar panels are manufactured to withstand certain amounts of normal environmental conditions. If the glass breaks on any solar panel it will reduce the overall efficiency of that panel which panels are broken that they be replaced as soon as possible.
     
  21. Is the material on the solar panels breakable? The solar panels are manufactured to withstand certain amounts of normal environmental conditions. If the glass breaks on any solar panel it will reduce the overall efficiency of that panel which could affect the overall efficiency of the system. We recommend that if any of the panels are broken that they be replaced as soon as possible.
     
  22. What type of maintenance do the panels require? The solar panels should be kept clean from dirt and debris as much as possible in order to obtain the most efficiency from the panels.
     
  23. Does the GPRM mobile solar powered water filtration system perform on cloudy days? Yes, even on cloudy days or cloud cover the solar panels will still generate enough electricity to run the system. Depending on the amount of sunlight the amount of water flow may be reduced but the system will still operate in limited light conditions.
     
  24. What is the warranty for the GPRM mobile solar powered water filtration system and individual components? GPRM warrants that its Products are free from defects in workmanship and materials for a period of ONE (1) YEAR.
     
  25. Can GPRM's systems be used as a longer term solution for providing drinking water in remote locations? GPRM can be a reliable and low cost long term solution to providing drinking water for up to 5,000 people per day per system. The systems excel in remote and off-grid locations where our rugged design, low maintenance requirements and ease of operations make their application optimal.
