Asprinn Reverse Osmosis RO Membrane Element 50 GPD/190 LPD | USA Made to Approx. 0.0001 Micron (GT13-59)
Asprinn Reverse Osmosis RO Membrane Element 50 GPD/190 LPD | USA Made to Approx. 0.0001 Micron (GT13-59)
The Asprinn Reverse Osmosis Membrane element can produce up to 50 GPD/190 Litres Per Day with a 1:1 permeate (clean water) to concentrate (wastewater) ratio, when used with a 200CC Flow Restrictor (on the waste line) on Chlorinated Mains Water at 70 PSI/482 kPa inlet pressure. Ideal for the reduction of TDS and common municipal water contaminants such as Heavy Metals, Fluoride, Minerals and Salts.

Disclaimer from the Manufacturer: The use of this product in and of itself does not necessarily guarantee the removal of cysts and pathogens from water. Effective cyst and pathogen reduction is dependent on the complete system design and on the operation and maintenance of the system. Permeate from the first hour of operation should be discarded.
How does an RO membrane work?
Reverse Osmosis membranes filter down to an ultra-fine level of filtration - down to 0.0001 of a micron - which is the reason why RO membranes can filter out minerals, salts, and metals (unlike carbon). Because this level of filtration is so fine, RO membranes do eventually clog up over time. How long you will be able to get out of your RO membrane, depends on the consistency of your membrane pre-filter maintenance, along with the starting quality of your water.

- HARD WATER (water that is full of salts and minerals) takes a bigger toll on RO membranes than water that is SOFT (water with a low Total Dissolved Solids rating). Western Australia, South Australia, the Northern Territory, and Queensland tend to have hard water, along with those whose main source of water comes from a bore. Thus the quality of water of the area in which you live is ultimately what will determine how long you get out of your RO membrane.
Is Pre-Filtration Required?
Please note that Carbon Pre-Filtration is recommended when using Reverse Osmosis Membranes with Chlorinated/Chloraminated or high-sediment water sources:
- Pre-Filters serve the dual purpose of blocking sediment particles and removing chlorine, which both cause damage to the inside of the RO membrane in different ways:
- Sediment particles physically damage the fine internals of an RO membrane, causing micro-tears that allow contaminants through to the "clean" side of the osmotic membrane, as well as blocking up the membrane which can cause the system to stop producing water and force an excessive amount of water to waste.
- Chlorine that has been dissolved in water creates corrosive hypochlorous and hydrochloric acids, which dissolve the delicate RO membrane (via a process called "ring chlorination" which disrupts the hydrogen bonding between the membrane's polymer matrix) and allows contaminants to pass through to the "clean side". Because this process occurs gradually over time, most people don't notice the taste of contamination until they change their membrane!
Is Post-Filtration Required?
Post-Filters go after the RO membrane to condition the water for final use.
- Pure RO water is typically acidic, and in some cases, pure RO water is used for brewing or in aquariums.
- Some users require "Zero TDS" in which case a DI Resin Post-Filter will be placed after the membrane to strip out any residual TDS.
- To boost the pH for consumption, carbon post-filtration is often used on its own to produce weak acid or pH-neutral water (as well as imparting a sweet flavour).
- Carbon is often used in combination with mineral media such as Calcite to produce pH-neutral to alkaline water, or with Magnesium and Potassium to produce alkaline to high alkaline water.
