Overview of Our Water Purification System
Water Collection
To date the most economical means is collecting rain water from the roof of buildings at schools and health centers. This requires installation of rain gutters, trash dispensing piping, trash filters and piping from the gutters to storage tank(s).
Water Storage
Water is collected in tanks specified for use in storing water. The capacity of the storage tank(s) is governed by the anticipated rain fall in the area, estimated rain fall intervals, and the size of the population being served. Tanks are elevated by various means to allow gravity water flow to the water purification equipment.
Water Purification Equipment
We designed the water purification system to achieve 99.999% bacteria and virus free safe water and have a system that can adjust the flow rate to meet each installation requirement. The main items of equipment are: pre-water filter(s), electric motor, one to five .9-micron ceramic filters (number of filters depends on water flow required) and special designed ultraviolet light(s). The number of UVL depends on the amount of purified water required. In addition, the system has numerous other components: pressure valves and shut-off valves of various sizes, PVC piping, various pvc pipe connections, semi-plastic tubing, cut-off water float valves and piping clamps.
Water Dispensing
Includes a water dispensing storage tank to hold water that has been purified and ready for use. The tank includes a shut-off float switch to cut off water flow to the tank when full. Piping is connected to the tank and is run to the point of use where drinking faucets are installed.
Solar Equipment
Most all rural areas of installation will not have access to electricity. Our system requires electrical power to operate water pump and UV lights. The main items of equipment consist of: solar panel(s), charge controller and storage batteries sized to the amperage required at each installation. Other items required are wiring of various sizes, cut-off switches, terminals, wire connectors and fuses.
Note: For security reasons all the purification and solar equipment except solar panels, require a secured area .

Water Purification System Details
Purification Stages :
- Stage 1 – Large particle pre-filtration. A stainless steel suction screen wrapped inside of a spun wound filter is used at the point of entry to remove any large particles.
- Stage 2 – Sub Micron Particle Pre-Filtration and Water Clarification. A 1-micron ceramic pre-filter that has been impregnated with silver is used to remove sediment and improve clarity prior to the water purification process.
- Stage 3 – Ozonation. Ozone is generated within the unit and is mixed with the water that has passed stage 2. Like Lorene, ozone is a powerful oxidizer. Unlike Lorene, ozone leaves no chemical residue. Ozonation improves water taste by destroying contaminants.
- Stage 4 – Ultraviolet (UV) Light Exposure. That ozone saturated water is flooded with ultraviolet light.
- Stage 5 – Photo–Oxidation. An Ozone/UV Photo–Oxidation process takes place. Photo – oxidation is what makes the purification process unique, combining the ozone and UV light. Like a catalytic converter in your car the UV “catalysts” the ozone to process a rapid and effective reaction in a compact space.
- Stage 6 – Activated Carbon Post Filtration. Water is filtered through an activated carbon filter. The purification process uses a high-performance, 2-micron cartridge with a special lead-absorbent media. This filter is designed to trap dissolved lead and chlorine, and very small particles.
- Stage 7 – Post Filtration UV. As further protection against microorganisms, the filtered water is again exposed to high density UV light.
System Operating Specifications:
- Power requirements: 12 V DC
- Power source- Solar/12 V DC Batteries
- UV exposure intensity: more than 22,500 microwatt seconds per square centimeter.
- Purification Post filtration model has been tested against ANSI/NSF standards 42, 53, and 55 for lead, cyst, chlorine and turbidity reduction, and for microbial reduction.
- 0.9 Micron Absolute Ceramic Pre-filter: Filter can be cleaned multiple times before replacement.
- Purification Post Filtration Module (PFM) Lamp: lamp life 10,000 on/off cycles.
- Purification Post Filtration Activated Carbon Filter: filter style formed radio – flow activated carbon w/Engelhard ATS™ for lead removal – filter life 10,000 gallons or water starts to taste bad or smell.
System specs will differ from installation to installation based on specific water flow rates.
