For a standard only roof collection water tank installation we normally recommend using a two stage (stage 1 and 2 below)filter system, this removes all the larger and then smaller particles from the water followed by a Ultra Violet treatment, if you are topping up from a council supply (chlorine) or have an odour rich water supply then add a Carbon Filter (stage 3 below)
For Town Water a single carbon filter (stage 3 below) or a 2 stage system (stage 2 and 3 below) is recommended, this reduces most of the chlorine and chemicals added to the water, an Ultra Violet Treatment system is not essential as the living organisms in the water should be eradicated by the chlorine and council chemicals. However if you are storing water onsite then look at the water tank filtration above.
Stage 1: 20 Micron Pleated - This removes larger particles ler than 20 micron from your water supply, taking out larger items like leaves and physical debris.
More info on these Cartridges:
Stage 2: 1 Micron Poly spun Filter - This removes smaller particles up to 1 micron in size, taking out very small particles in the water even parasites like Giardia (opens in new window)
More info on these cartridges:
While we normally recommend a 1 micron Filter, in some rural applications it is necessary to revert to a 5 micron filter esp where high deposits of silt are coming out from a bore, there information is on the same 1 micron filter page above (just select the 5 micron option), We would recommend installing a 1 micron Filter and if you are finding a significant water pressure drop before 6 months, replace the filter with a 5 micron option.
Stage 3: Carbon Filters are ideal for reducing odours, taste and chlorine in your water supply, we have options of solid block carbon filters and granular activated carbon filters. They are similar in design however the block carbon filter (CTO) can reduce water flow but produce a better result and granular carbon filters (GAC) can allow better flow rates however water to channel to a degree making them slightly less effective.
This is a bit of a debate however when we make recommendations relating to Filter Sizes 10 inch or 20 inch we recommend that it depends on usage. We believe that replacing your water filter cartridge more regularly is better to keep water clean and bacteria free, but within reason. A guide to water filter replacement is every 6 months, if you have a large house (i.e. 3+ bathroom and washing machine, dishwasher and...) then go for the 20" filters if you have a small house or bach (i.e. 1 bathroom etc) then 1" filters are plenty. The standard 2 bathroom house, depends on how much water you use, if you are not very conservative, don't want to loose pressure, have a larger family then go for the 2" filters, if you live in a mid sized house with fewer people of very conservative then 10" filters.
Great buy
great service and great product thank you very much.
BWT has stepped up, providing great service and product
Thanks Craig for the Second Review, hope my info to swap the flow direction on the filters helps you get the most out of them :-)
Good priced filters A++
Very quick delivery. Thankyou
System Orientation – Our Advance UV systems should be installed either horizontally or vertically, with the outlet port at the top of the system and the inlet port at the base, as shown in the diagrams below. Ensure ballast is kept dry and away from any potential condensation. Use drip loops so moisture does not run down lamp harness or power cord and into ballast. Prior to installation, remove protective caps from inlet and outlet ports of the UV reaction chamber.
