Filtering/pre-treatment

The unit is not a filter and therefore water with particulates should have as much floating and suspended material filtered out prior to the disinfectant treatment. Pre-cleaning the water prior to treatment greatly improves the water quality and improves the efficiency of the chlorine-disinfectant gas mixture that kills the microorganisms.

Suspended mater in water reduces the microbiocidal efficacy of chlorine. Therefore filtering water on the front end of the New Life water purifier will greatly reduce the disinfecting time in the treatment tank. Pre-treatment technologies for removal of suspended matter from water suitable for the chlorination application could potentially include:

  • Settling of sedimentation with time
  • Fiber, cloth or membrane filters
  • Granular media filters
  • Slow sand filter

All of the above methods will vary in their ability to remove particles from water, depending on the nature of the suspended matter. Especially important is their size and density.

Question to consider:

Is the current water supply filtered in any way?

Water Sources

Water from sources containing such things as hazardous waste, hazardous mineral or radioactive contaminants is far beyond the scope of this application and the intended use of this technology.

Questions to consider:

  • Is there water available in the community?
  • Is there a constant source of water?
  • What months out of the year is water available?
  • What type of water source is available?
    • Rain
    • Tanker truck
    • Municipal
    • River or stream
    • Lake or pond
    • Reservoir
    • Spring
    • Hand-dug well
    • Drilled well (bore hole)
    • Other
  • Who owns the current water source?
  • If privately owned, is the community use still guaranteed access to it?
  • How is the water currently being stored?
    • Not stored
    • Large tank (volume?)
    • Small drums
    • Reservoir
    • Cistern
    • Lake or pond
    • Other
  • What kinds of water storage containers are available to use or purchase?
  • Has the current water supply been tested?
  • Is the current water supply contaminated?
  • Does the current water supply have chemicals in it?
    • If so, is the chemical(s) known?
  • How was that determined?

    • If it failed, why

How It Works

  • The water purifier is a simple electrolytic generator using the electrolysis of salt water to generate powerful disinfectant products to eliminate waterborne pathogens from water.
  • The salt is sodium chloride, which is common table salt.
  • One of the main disinfectants generated from the salt is chlorine gas.
  • Chlorine is considered to be a poisonous gas and one must avoid breathing it, however, when properly used, it can be utilized safely to effectively kill microorganisms in water.
  • The unit does not serve as a filter for particulates, therefore water that is to be treated should have as much floating and suspended material, if present, filtered out prior to the disinfectant treatment.
  • Pre-cleaning the water prior to treatment greatly improves the water quality and improves the efficiency of the chlorine-disinfectant gas mixture to kill the microorganisms.
  • If necessary this can be done by filtering the water through cloth, sand, or if possible allowing the sediment to settle to the bottom of a container prior to use.

The purifier generates chlorine by an electrolysis process by separating the salt (NaCl) into its components: Sodium (Na) and Chlorine (Cl). The purifier sorts the sodium ions from the chloride ions using the 12 Volt DC charge from a car battery or other source of direct current

The Chlorine gas that is produced in the Chlorine Generator is drawn into the water supply using a Venturi Injector providing the necessary chlorination of the water in the treatment tank. The appropriate chlorine level is obtained (a few parts per million or milligrams per liter) and the water is allowed to mix with the chlorine for at least an hour to allow sufficient contact time to kill the bacteria and other pathogens.

After at least one hour’s time, the water can be transferred to a “Use Tank” for distribution to the water users. The “Treatment Tank” and the “Use Tank” are part of the water purifying process but are not included in the New Life International Water Purifier package. The tanks are either procured locally or already available on site. They may be temporary tanks or permanent facilities.

In addition to economically purifying water, the New Life International Water Purifier has other benefits:

  • Portability: The packaging weights about 20 lbs and can be easily transported from village to village.
  • Customer Service: Technical support and ordering replacement parts is available through the New Life Web Site and via email.
  • Potential to use solar power to recharge battery: Ideal for locations where regular electric service is not available.
  • Water from any source: Water can be from wells or surface water
  • Built for various environmental conditions: Designed to operate in extremely remote areas and under harsh conditions almost anywhere in the world.
  • Environmentally Friendly: Does not consume valuable or limited natural resources.
  • Minimal Maintenance: Virtually maintenance free, no moving parts.

Proven Success:

The New Life International Water Purifier has been in operation for over five (5) years. Over 800 purifiers are currently operating in 58 different countries from Thailand to India to Kenya to Zambia to Costa Rica to Haiti to Brazil.

Distribution

Studies show that the use of containers with narrow openings for filling, and dispensing devices such as spouts or taps/spigots protect the chlorinated water. Many container designs also have handles, are lightweight, are made from durable, UV-resistant plastic. It is vitally important to treat and store chlorinated water in containers that can’t be re-contaminated from the introduction of microbial contaminants via contact with hands, dippers, other fecally contaminated vehicles.

Questions to consider:

What kinds of water storage containers are available to use or purchase?

Follow-Up and Maintenance

  • The local residents need to appreciate the value of the water purification technology and take ownership to maintain the process.
  • Responsible individuals in the community need to maintain, self regulate, and govern themselves so that the technology is not placed in the hands of everyone and at the same time no one as is often the case in tribal communities.
