Due to the high demand for river water and dam water filters we have come up with this solution... This unit uses x4 20" x 4.5" bigblue systems which are 100% standard size.
1)The filters are available everywhere being standard size
2)This unit actually works giving no reduction in flow rate whatsoever (until blocked)
3) The water has plenty of contact time with the carbon filter media removing all taste, all if not most colour, and all odour!
The unit has x1 Pleated washable sediment filter first in-line followed by x3 10 micron carbon filters that have a super dense qty of carbon to ensure the taste, colour and odour reduction...
1)Ok, so ideally you need to pump the dam water to a settling tank through a sprinkler to airrate the water
2)Trickle feed the water through our "river ripper" unit as slow as possible (like 1L per minute) into your rainwater storage tank
3)Run the water through the ultra violet light sterilizer (to kill parasites ect) this water will be fine for everything besides drinking...
4)Install a reverse osmosis unit under the sink for drinking
Everything comes down to contact time with high turbidity..
**** YOU SHOULD CONSIDER ADDING THE ULTRA VIOLET LIGHTS IF YOU WANT TO ELIMINATE ALL PARASITES LIKE GIARDIA, ECOLI, CRYPTOSPORIDIUM... ALSO, THERE MAY BE INDUSTRIAL OR BIOLOGICAL WASTE LIKE MEDICAL WASTE DUMPED IN YOUR RIVERS, SO THE ULTRA VIOLET LIGHT WILL ELIMINATE MOST OF THESE CONTAMINANTS BY KILLING ANY BUGS THAT ARE PRESENT... jUST ADD THEM FROM THE DROP DOWN MENU BELOW...
