Frequently Asked Questions

Does magnetic water treatment work and does it remove the "salts" from the water?

 

It does work providing that the water to be treated is suitable. To explain firstly you need to understand the principals behind magnetic water treatment. Calcium dominated water is the easiest to magnetically treat providing that the levels are not too high. As with all water treatment an analysis of the water is critical prior to attempting any form of process to enable it's use. Calcium bonds with oxygen as well as other "salts" present in the water. This process converts the Calcium to Calcium Carbonate. It is this Calcium Carbonate that when used in irrigation causes soil salinity. It collects in the top soil and inhibits plant growth. It also coates the inside of pipes and blocks drippers etc.. By applying strong magnetic forces to the water stream the Calcium separates from the oxygen molecules unlocking the "salts" and allowing them to be delivered in their natural state. If this is irrigation then it allows the plants to absorb the available "salts" as they are required. However, as you can see, it does not remove the "salts" it just unlocks them and makes them available for use. Beware of companies marketing magnetic treatment equipment who do not first obtain a full water analysis and who also make dubious claims as to what magnetic treatment will achieve.

 

What are the for's and against's regarding Reverse Osmosis Desalination?

 

Again the water being considered for this process must be analysed to see whether it is viable to do so economically speaking. There are a number of things to consider when weighing up the options. The condition and quantity of the water, available power at the proposed site, the position and cost for the "reject brine" evaporation dam and the amount of product (desalinated) water required. If the sums add up then reverse osmosis is the way to go but careful consideration of all the associated factors needs to be undertaken first.

 

My bore water is stained brown. My drippers are constantly blocking. What is this a sign of?

 

Brown coloured bore water usually indicates the presence of Iron. The iron can be removed by chemical flocculation and or filtration. However, underground water can also contain Iron Bacteria which feed on the soluable Iron. This presents a problem whereby the Bacteria can turn the water stream into a mushy state which can block and damage pumping equipment as well as drippers etc.. The bore hole can be treated to kill the Bacteria within the immediate vicinity and in most cases clean the pumping equipment as well. However, this is usually not a forever fix. The bore must be treated either yearly or whenever the Bacteria reappears in the water stream.

 

I store rainwater and use it for drinking etc. Is this a risk to my health?

 

Generally speaking if your collection system is in good condition ie; tanks, gutters and downpipes are free from rust and debris and vermin free and first flush diverters are incorporated prior to delivery to the tank then the risk of high Bacteria or Virus infestation in the rainwater is minimised. However, it is not eliminated. There is always Bacteria present in rainwater that is why it is classed as non potable - not suitable for human consumption by the WHO. By installing simple filtration and disinfection (Ultra Violet) equipment in the delivery system the risks associated with the use of rainwater can be substantially reduced.
