5 Stage RO System 400GPD for Home Fishkeeping or Window Cleaning

The 5 stages of filtration are:

Stage 1

• A 5-micron sediment filter made of 100% pure polypropylene fibres. It removes dirt, sand, and rust.

Stage 2

• A Granular Activated Carbon Filter is composed of High-Performance Activated Carbon. It removes free chlorine, odours, organic contaminants, pesticides and chemicals.

Stage 3

• A carbon block filter is composed of high-performance carbon. It removes trihalomethanes, pesticides, and volatile organic chemicals (VOCs).

Stage 4

2 x High Rejection Thin Film Composite 200 GPD Reverse Osmosis Membranes with a total capacity to produce up to 1514 litres of purified water per day. This membrane removes contaminants present in water, including, up to 99% of dissolved salts, lead, copper, barium, bacterial by-products, oestrogen, and silica.

Stage 5

A single Post-Carbon Filter, designed to enhance taste, removes residual impurities and odours from the tank and provides finer conditioning of the purified water.

Important:

1. This system requires a minimum of 29 PSI (2 BAR) to work. This is for the booster pump to operate.
2. Operating the system at a lower pressure than the minimum can cause damage to the pump.
3. Ideal pressure depends upon incoming water temperature but around 60 PSI (4 BAR) is acceptable.
4. Reverse Osmosis Systems wastewater to make water, and this should be done at high pressure as the water is being forced through microscopic holes which catch contaminants.
5. This is normal and the same with all RO systems as this is the way the membrane rejects the impure water, which goes to the drain, to produce pure water.
6. The system works optimally at 80-90 PSI (5.5 - 6 bar), and to get to the quoted output, we'd recommend running the system on or around this pressure.
7. This allows the system to reduce the waste water to pure water ratio and work faster at producing pure water.

To use this system in a window cleaning or aquatic application which requires zero (0) TDS water, we strongly recommend pairing an additional De-Ionising Resin filter with this RO system to assure total contaminant removal. 10" housings with drop-in refillable DI cartridges and inline DI resin cartridges are available to buy.
