How To Build A Water Ioniser


The latest white goods technology to hit the market place is an acid/alkaline water charger. With a price tag between $1000 to $1300 (Aud) for a single commercial unit, its not hard to see why some people may choose to build and experiment with their own home made designs. The following plans will describe in detail how to make an acid/alkaline water charger to experiment with your own charge water at home. The following plans involve simple to understand step by step instructions. The price of the materials to make your own unit should set you back between $50 to $70 (Aud).


Acid/alkaline water is also known as micro-cluster water? By supplying a low voltage charge (12v) to a positive electrode in one partition of the charger container and a negative electrode in the other partition of the container, you can get ordinary tap water to separate into acid water at the positive side, and alkaline water on the negative side. The water actually undergoes a change of its electrical state. It does this by changing the pH level of the water. Negative electrons are attracted to the positive protons on the positive plate side. The negative plate partition of the water charger builds up what is termed as a charge cluster of negative Hydrogen ions in the water. Where as the positive plate partition builds up a charge of OH ions. Commercial units claim negative charge clusters of around -250 to -350 mV. Why is this charge cluster water beneficial to people? It has been document by commercial manufacturing companies that acid/ alkaline water units can assist in helping many human ailments. Ailments like arthritis, heart disease, stroke, osteoporosisfatty acids, and metal build up in the body etc. There are many pages on the Internet devoted to other people's testimonials as to these health benefits. I don't think charge cluster water can do any immediate harm to people in the short term, as naturally falling rainwater has a similar build up of negative charge. This type of unit allows people to have healthy water on demand, while at the same time allows them to use the acid water for rashes and skin aliments. Acid/Alkaline water can even be used in the garden.


The pH scale ranges from 0 on the acidic end to 14 on the alkaline end. A solution is considered neutral if its pH is 7. At a pH of 7 water contains equal concentrations of H+ and OH- ions. Substances with a pH less than 7 are acidic because they contain a higher concentration of H+ ions. Substances with a pH higher than 7 are alkaline because they contain a higher concentration of OH- than H+. The pH scale is a log scale so a change of one pH unit means a factor of ten in the concentration of hydrogen ions.

  • Purchase - one Click-Clack (NZ) 2.4 litre storage container, the upright type, these are thick, fairly rigid plastic.
  • One Cuisine 6 litre storage container.
  • A rectangular plastic basket/container, for a grill, the type shops use for displaying small parts, it needs to have grid or mesh bottom and sides so that water can pass through, ($2 shops, Emporiums).
  • A packet of small plastic screws and nuts about 10mm long, (Electronics parts store, Dick Smiths).
  • Two small crocodile clips different colours for positive and negative, (Electronics parts store, Dick Smiths).
  • Electric power point adapter 230v - 12v or 24v, some cell phone chargers are 12v. You may find one in a second hand store, (Dick Smiths)
  • A synthetic chamois (PVA) (Hammer Hardware).
  • Two Stainless Steel plates about 1mm thick, 10cm wide and 5mm higher than the inside of the container. For these containers 10 x 19 and 10 x 22 centimetres
  • Cut a piece of the basket out at least 10cm square or 10 x 15 cm.
  • Mark out one large side of the 2 litre Click-Clack container at least one cm smaller all round than the plastic mesh and the top about 5cm below the top of the container.
  • Wedge a block of wood inside the container to support the side and drill as many 6 to 7mm holes as you can.
  • Smooth off any burrs on the outside.
  • Drill holes in the corners of the plastic mesh for the plastic screws to go through, and every 2 to 3cms along the sides.
  • Hold the mesh over the container where it will go and drill a hole through one corner.
  • Fit one screw in the corner, then drill through the opposite corner and fit a screw, then the other corners.
  • Drill through the holes in the sides.
  • Remove the screws and mesh and the block of wood.
  • Smooth off the burrs on the inside of the container and the outside.
  • Wet the chamois and wring out and cut a piece slightly larger than the plastic mesh.
  • Hold the mesh over the chamois on a board and bore holes in the chamois where the screws go through, or mark the holes and then bore holes in the chamois.
  • Remove any straggly bits from the chamois and rinse it a few times and wring it out.
  • Rinse out the container and dry it.
  • Assemble the mesh over the chamois onto the container and fit the screws.
  • Rinse out the whole ioniser in and out.
  • Cut off the plug on the end of the adapter 12v lead and fit on the crocodile clips, if you have a test meter you can check polarity. Otherwise you can try out the ioniser, the acid water has a brown tinge to it and should be in the large container, if the brown water is in the small container reverse the clips.
  • The small container is placed in one corner of the large container with the permeable membrane exposed to the water, the smaller SS plate is placed opposite the membrane, the other plate is placed in the short side of the large container.
  • Fill both containers to about one centimetre from the top with water, it is preferable to use a filtering device.
  • With a clean membrane the alkaline water will be about 10 Ph in 8 hours but as the membrane gets browner you will need to increase that, my ioniser is left on for 12 hours. You will know it has worked by seeing lots of bubbles on the sides of the container and the water in the large container is brownish. When emptying lift out the small container quickly and tip the water to a corner away from the membrane and into a jug.

Two glasses nearly full of water placed together, a stainless steel teaspoon in each leaning against the further extremities, a 6 x 4 cm piece of plastic over the join and a 10 cm long wad of cotton or rayon wool over that. You can use cloth or anything that will allow water to pass through it. Plug in the adapter and connect the crocodile clips to the spoons and switch on, should be ready in four hours. Drink the clear water, put the brownish water on the plants.

It is preferable to use a water filter to eliminate the majority of the pathogens in our water supplies, if you make the colloidal Silver generator a teaspoon of CS in four litres of water stirred around will kill pathogens and viruses.

NOTE: A number of people have asked for diagrams, photos or more details on how to build an Ioniser. Unfortunately David passed away in 2006 without leaving any more details on how to build an Ioniser.
