Reverse Osmosis Systems
Pure Hydroponics can provide a range of Reverse Osmosis Water Treatment Systems
A pure water supply is one of the key ingredients to growing a perfect hydroponic crop.
By removing impurities out of the water supply a grower using a recirculating system does not have to purge or dump their tank nearly as often. This is a major cost saving for them by conserving valuable nutrients.
Drip systems and recirculating systems are kept much cleaner, which means there is less likelihood of dripper blockages or a build-up of unwanted precipitates.
Only the pure elements supplied by the nutrient formulation are made available to the plants rather than any unwanted impurities from the water supply which can restrict nutrient uptake by the plants.
After a water supply is treated with a reverse osmosis system the water is nearly 100% pure. This makes it a valuable source of drinking water for the home as well as feed water for the hydroponic system.
Option 1 – Pentair PRF RO System (No Electricity Required) (Ex Stock NZ)
The Pentair Water Reverse Osmosis System delivers up to 2600 litres per day using typical line pressure, which eliminates the need for a supplemental pump in most applications. That’s enough capacity for many small commercial hydroponic systems, at the price of a residential system.
Option 2 – ROS COM 800 (Imported) – With Built-in Booster Pump
The Ros Com 800 Reverse Osmosis System is capable of making between 3028 – 3785 litres of pure water per day.
The specifications achieved when shop-tested at a 46% recovery rate are as follows:
System Pressure 190psi (maximum allowable pressure 200psi)
Treated water 2.1L/min (permeate)
Total Flow 4.6L/min
Percent recovery 46%
Treated water (permeate) quality 1.2 micro-siemens (0.0012 millisiemens (EC))

Ros Com 800 RO Unit Specifications
As with all Reverse Osmosis systems a percentage of the water fed into the Reverse Osmosis system comes out as wastewater containing the removed impurities. This wastewater can be diverted down a drain to waste or used on soil crops. It does not affect the treated water total.
The main component that would ever need replacing is the replacement membrane — XLE-4021
Typically the membrane should last about 2 to 3 years.
The pre filters are the 20” slimline type with the first being a 5 micron pleated followed by a carbon block cartridge for any chlorine removal.
20CTO/2 (Carbon Block)
Typically these would be changed every 6 months.
The ongoing maintenance costs are therefore minimal compared to the wide range of benefits gained from using a Reverse Osmosis system.
If the water supply is of unknown quality and may have higher sediment loading at times then we would strongly advise another large prefilter be included before the built in ones to ensure good sediment holding capacity.
A 20” Jumbo housing with 5 micron pleated would be the best option. (20BWH) (Filter housing) (one off price) with a replaceable 20BPF05 cartridge filter insert
A cartridge change would be required approximately every 6 months.
The total system is very simple to install and use.
