Water Scrubber

Introduction

Build your own water scrubber to further clean and purify house hold tap water... The purpose of the water scrubber is to remove unwanted dirt and heavy minerals from house hold tap water. This will leave the water clean, clear and tasting very similar to rain water.

The following plans will show you how to make a simple water cleaner/scrubber that will clean dirt, heavy minerals an a range of other additives out of any type of water. The water tested includes bore water, ground water, salt water ,bacterial and some artificial additives in house hold water. There is no guarantee that once water is scrubbed clean, that the water will be fit for human consumption. The fitness of the water for human or live stock consumption depends entirely on what type of substances and bacteria are in the water to begin with. Salt for example is difficult to removed entirely from the water with this cleaning process. The information given in these pages is for the average home handy man to experiment further with cleaning dirt, heavy minerals and certain bacteria out of ordinary house hold tap water. The experimental model given on this page is but a simple model that any one can build with some simple ingenuity, or can be readily made at any machine shop for a minimal price. The electronics needed to run the water scrubber is just a simple every day battery charger. Like the charger used to charge any automobile battery. The battery changer can be purchased from any supermarket, automotive, hardware or electronics store. The voltage an amperage required to operate the water scrubber unit is 13.8 volts at around 1 to 6 amps, depending on the minerals an electrolytes in the water. The power output of the battery charger is of a low wattage, and therefore is considered reasonably safe. Although every precaution should be exercised when using the 110/220/240v mains electrical power.

Getting Started:

Cutting and drilling the plates :

If you have purchased a 500mm x 100mm x 1.6 mm large sheet of 316 stainless steel plating, then you need to cut the 5 @ 100 x 100 mm plates from this larger sheet. You will need to use a cutting wheel designed to cut stainless steel, and the correct cutting machine. You may like to purchase these plates already pre-cut from a welding or metal fabrication work shop. Using a steel ruler an a scriber or pencil, mark one of the cut out plates with two diagonal lines from corner to corner. This will give an 'X' across the plate which will give you the dead centre of that plate. see figure 1.

figure 1. (100mm x 100mm)

Using a centre punch and a hammer, centre punch the first drill point in the metal at the precise centre of the cross. This is the centre where you will drill all five plates at the same time. Now place the other 4 plates under the plate you have just centre punched. While using a clamp or metal vice of some description, clamp all of the plates firmly together. The plates should be flush an equal on all sides, with all plates being as symmetrical as possible although not critical. No plate should overlap or stick out sideways from any of the other plates once they are all clamped. Now using the 5.5 or 6mm drill bit, drill through all 5 plates at the same time. You will need some physical pressure and an oil lubricant to drill through all the plates in one process. Important, once you have drilled through all 5 plates, you must undo the clamp and remove any 2 plates away from the rest of the stack. Do not re-drill these two plates. Replace the clamp back onto the stack of 3 plates and tighten firmly as before. Now change the drill bit in the drilling machine and fit the 12.5 mm drill bit. You are now required to redrill these 3 clamped plates only out to the larger 12.5 mm drill bit size. These 3 plates have larger holes as these holes will fit the 12.5mm x 0.75 - 1mm wide collar on the nylon spacers. Don't worry if you don't understand this collar function just yet... (see figure 4.)

If you wish to go to additional expense you may get the 5 plates lathed round to get a more professional look and finish to your plates. This is totally optional and left to your own preference. The more plate area the better the system works. Lathing the plates round only improves the cosmetics, which is at a small but negligible expense to the overall operation of the unit.
