Choosing the right filter
What you Need to Know Before Purchasing a Reverse Osmosis System.
What is RO filtration?: Reverse Osmosis is a water purification technology that uses a specialized material to remove ions,molecules , and larger particles from drinking water. Water is forced through a semipermeable membrane. This membrane only allows pure water to pass through its walls, all other impurities are rejected.
What is reject water?: During the filtration process, RO systems reject a large quantity of contaminants. These contaminants are usually made up of large molecules that can not pass through the RO membrane. They are then carried away through the waste water hose in a super concentrated water solution. The reject water is typically produced at a rate of 75%-50% more than the filtered clean water. Restricting the Flow of the Reject side allows for a higher clean to reject ratio. This also causes a build in the RO membranes which may shorten your filters life. High Pure Water installs back flush assemblies on all upgraded 1:1 filters. The flush valves allows you to periodically clean your RO membrane to prevent build up from occurring which extends the life of your RO system.
What are Pre filters?: Pre filters are used to remove particles of contaminants before they reach your RO membranes. Think of these as your first Line of defense. High Pure Systems are all equipped with 2 high quality pre filters. The first filter in the run is a 1 micron Sediment filter. Sediment Filters are used to remove rust flakes from the water pipes, sand grains, silt, small pieces of organic
matter, clay particles, or any other small particles in the water
supply. Our filters also come equipped with a carbon block filter. Carbon filters are used to absorb a large amount of chemicals and organic substances
in domestic water supply. These substances include sodium sodium hypochlorite, and sodium hydroxide which are used by municipalities to disinfect , and prevent bacteria from growing in potable water. Because the carbon filter also absorbs organic particles, bad smells and tastes are scrubbed away in this stage. After being processed by the pre filters, your water still contains small contaminants. This water is then completely scrubbed clean by the RO membrane. High pure water filters remove 95%-99% of all contaminants in city water.
What is GPD?: GPD is an acronym for "Gallons Per Day". This term generally used to approximate the average amount of clean water produced in a 24 hour period of time.
What size filter do I need?: This depends on the amount of water you need produced per day. The Piranha 100 is capable of producing 100 gallons of clean water per day (5 gallons an hour, 1.25 gallons every 15 minutes). The Hydra 400 produces 400 gallons per day ( 16.50 gallons and hour, 1.1 gallons every 4 minutes). The question you should ask your self is How fast do you need clean water?
Do I need a higher Clean to waste ratio?: Reverse osmosis systems produce reject water. This water contains all the contaminants that were removed from the input water source. The average reverse osmosis system will produce a 2:1, or 3:1 ratio. This means that the system will produce 3 parts waste to 1 part clean water. These ratios are very efficient and prolong the life of your RO membrane. 1:1 ratios cause the membrane to work harder, which can cause build up . This build up shortens the life of your filter. There is a solution! High Pure Water recommends back wash valves installed in 1:1 ratio Reverse osmosis filters. The back wash valve assemblies allows the user to periodically flush the build up from the membranes. Proper flushing of the membranes may prolong the life of your RO system.
Do I need a Shut Off Valve?: Shut off valves cut the flow of water once it senses a reservoir is full. This valve is used in systems where filters have been set up to fill reservoirs automatically. The shut valve works in concert with a float valve. Once the fluid reaches a preset level in the tank, the Float valve will close which causes the Shut Of Valve to stop the water flow to both clean and reject water.
