Re-Use Waste from Reverse Osmosis (RO) Filter. Many of us use Reverse Osmosis Filters (RO filters) to purify Drinking Water, in areas with high TDS (Total Dissolved Salts) content in the Water. Around 75% of the Water fed into a RO filter, is wasted. Only 25% gets extracted as drinking Water.
Filtration is the only water purification process that will remove chlorine and chlorine byproducts from water. It is also the only water purification process that reliably and completely removes harmful pesticides from water. Single media filters will not remove mineral compounds from water. The true power of the filtration process lies in multimedia filtration technology. By using multimedia filters, select minerals can be retained in water while more harmful or useless minerals and chemicals can be removed.
