COMPACT REVERSE OSMOSIS SYSTEM

For a long time, there has been a call for a compact Reverse Osmosis System to suit installation in areas with limited space, such as tiny homes and caravans.

In the past, we have discouraged these systems from being installed, because of excessive vibrations and the potential for leaking (or damage) to such filter components. Instead, we have recommended using portable ROs that are not used inside but rather outside where water overflows and can't cause any damage.
 
The call recently has been for RO's to be more compact and fully automatic which means they need to be a permanent fixture (installed). Modern connectors and quality components now make it possible for this to become reality. Thus, for this system, we have done away with the removable screw-off housings which are notorious for vibrating off in transit, and have replaced them with fully-sealed inline filters, changed all the connectors from screw style to push-fit connectors so they cannot work loose, then made some healthy changes to the finished product.

As you read through the features of the Compact Reverse Osmosis System, we're sure you will agree that finally, technology has permitted us to offer a safe (dry) method for producing reverse osmosis water automatically and safely in the confines of your caravan/motor home.

In keeping with its two big brothers, the 1-26 7 Stage RO & the 1-70 Shuttle Portable RO, we are pleased to introduce the NEW Compact Reverse Osmosis System.
 
Features:
 
 
1/ Dimensions

Weight 1.59 kgs (Dry) 
Length: 34cm 
Compressed width: 15cm 
Tank height: 34cm 
Tank diameter: 23cm
 
2/ pH neutral final carbon filter Exclusive! 
This is a new feature to our RO range. We are all aware that RO water can be, and often does produce acidic water, this is when the pH of the water is lower than 7 pH.

This filter is the final stage before drinking and combines the benefit of coconut carbon for taste and odour with pH neutralizing calcite marble, a natural store that raised pH as the water passes over the stone. From this, we can guarantee you safe pH neutral fresh healthy water.
 
3/ Magnetic Treatment
On the way from the final carbon filter, the water passes through a negative magnetic field which activates the water for further health advantages. This has been used in our 6 & 7 stage system for years with rave reviews and stories of great health advantage from people with all sorts of health inflictions - from arthritis to cancer sufferers. An important factor in health and well-being is water consumption, and the fact is that if the water is fresh and clean, people will drink more of it.

Negative Magnetic Treatment
We are the leaders in Magnetic Water Treatment systems in Australia, exporting our Fluid Reactor Magnetic Systems to 8 countries around the world. 

We have not promoted or actively been involved in the Health Industry because of our commitments to our core Water Treatment and Filtration business. However, once again we have been encouraged to build and supply negative Magnetic Water Treatments for human consumption and the evidence has been overwhelmingly positive.

Magnetic energy is widely used in Water Treatment and we helped pioneer this technology in Australia. This inevitably led us to develop and supply a technology called negative defusing technology, meaning that when put it in reverse it activates negative energy into drinking water. 
So many customers have benefited from this technology, reducing the symptoms of kidney stones and calcification of the arteries, along with so many other advantages in drinking negatively charged water.

4/ Ultra Compact
We have made this system as compact as possible given the futures it offers it's a fantastic space saver. The tank has been reduced from 12 to 8 litres. It's made of steel and therefore incredibly durable - just be sure you have it appropriately secured, as undoubtedly if it's full of water it will pack a punch if it comes loose. We called the system compact for this very reason, as we recognize the importance of space-saving in this environment.
 
5/ Competitive
Just because it's small doesn't mean it produces a less effective result, in fact, quite the opposite. The membrane used in this system is probably the most successful ever made. The results with this system will equal or better that of any other system on the market for any amount of money you might decide to spend, so we are confident to stack this Compact system against anything on the market.
 
6/ Low Pressure Membrane
Probably the most successful membrane ever made. Most membranes including those used in our 6 & 7 stage system only function from 40 psi upwards. In a van situation, this means your pump may be working overtime cutting in and out. Also, many low-pressure pumps have trouble maintaining a high enough pressure to make standard membranes work effectively.

The 13-3LP Low-Pressure Membrane has been purpose-built to operate in low-pressure situations from 20 psi to 120 psi. It's the Commando of the membrane world if you like - because of the extra cost of these membranes we don't use them as our mainstream membrane. However, they are purpose-built for this particular application and well worth the extra few dollars.
 
7/ Drain Valve
Because water conservation is important for travelers especially, we have been researching and working hard to reduce the amount of wastewater that our compact RO systems produce. Even though waste is a fact of life with RO, we have managed to reduce the waste to 50/ 50 (variable). The drain valve we use is a 200cc valve, which helps keep back pressure on the membrane and reduces water wastage. Most competitor systems use valves varying from 250 - 400 with waste to water ratios varying from 2 -1 to 6-1.
 
8/ Back Up Service & Technical Support
We build our RO's and service them - so we know them inside and out! Call us if there are any issues on 1300 888 008.
 
9/ Water Production
At a constant pressure of 45 psi, you could expect to produce about 8 litres per hour. The storage tank also holds 8 litres, so as soon as you extract water from your RO system, it automatically begins producing water and refilling the tank.
 
10/ Storage and Maintenance when Not In Use
Note: We realize also that holidaymakers come and go, often taking off for several weeks on the road and then coming back home, so considering the small size of the Compact RO, it's possible to disconnect the system while it's not in use and store the complete system in the fridge ready for the next outing. Doing this will extend the life of the carbon cartridge. Then, simply do a full tank flush when you're ready to go again!
 
PLEASE NOTE: REVERSE OSMOSIS SYSTEMS PERFORM OPTIMALLY ON CHLORINATED (MAINS/TOWN) WATER, AS THE PRESENCE OF CHLORINE KILLS THE BACTERIA/FUNGI/YEAST. THEREFORE, REGULAR & CONSISTENT WATER DISINFECTION IS STRONGLY RECOMMENDED FOR RAIN/TANK/POTABLE BORE WATER* SOURCES PRIOR TO USING A REVERSE OSMOSIS FILTER SYSTEM. FAILURE TO ADEQUATELY DISINFECT THE WATER WILL RESULT IN BIOFOULING OF THE RO MEMBRANE (I.E. A BACTERIA/FUNGUS/SLIME COLONY WILL START GROWING INSIDE THE MEMBRANE WHICH WILL PUTREFY YOUR FILTER SYSTEM & RENDER THE RO MEMBRANE UNSALVAGEABLE). 
 

INSTALLATION - Please note this system is WaterMark Certified to Australian plumbing standards (AS/NZS 3497), and will need to be installed by a licensed plumber. Simply order online with free shipping to your home, and once it arrives any local licensed plumber will be able to do the installation (the system also comes with instructions)!

How often should you change reverse osmosis water filters?
Filter Replacements & Maintenance Schedule

To maintain the optimum level of filtration year-round, and to ensure you get the maximum life out of your RO membrane (the engine room of this system), we strongly recommend a consistent filter maintenance schedule. 

  • Pre-Filters

    Every 6 months you will need to change the pre-filters, which help protect and extend the life of the membrane. Some people neglect to keep up with the maintenance of the pre-filters, thinking that the RO membrane will take care of it! However, the RO membrane is the most delicate and expensive filter within any RO system, so it's worth protecting your investment!

    The pre-filters thus serve the dual purpose of blocking sediment particles larger than 5 microns and removing chlorine, which both cause damage to the inside of the RO membrane in different ways:
    • Sediment particles physically damage the fine internals, 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! 
  • Reverse Osmosis Membranes*

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, whilst we have specified a recommended maintenance schedule (below), the quality of the water in the area you live, is ultimately what will determine how long you get out of your RO membrane.
    • *If you are on hard water, at the 2-year mark, simply go for the FULL Replacement Pack (which includes an RO Membrane). Note - cases of extremely hard water may get less than 2 years out of an RO membrane. 

Australian Water Hardness Map Guide

  • Post-Filters

These are all filters that go after the RO membrane to buffer the pH back up from an acidic state to an alkaline state, and "perfect" the water for final consumption. Over the course of a year, the diffusion of the alkalising minerals into the water will significantly diminish, whilst the carbon post-filter will eventually exhaust its capacity to adsorb residuals.

***IMPORTANT INFORMATION ABOUT WATER SANITATION***

Disclaimer: Do not use or drink microbiologically unsafe water or water of unknown quality without adequate disinfection.

FSA’s Recommendation for Rain/Tank/Potable Bore Water*

If you use Rain/Tank Water and Potable Bore Water (*i.e bore water that has been tested to the Australian Drinking Water Guidelines and deemed suitable for drinking purposes per the Guidelines’ aesthetic, health and safety recommendations), please see below our recommended filtration schedule to ensure safe drinking water:

  1. External Sediment + Carbon Pre-Filtration to Prevent Tank Clogging + Improve Initial Taste & Odour
  2. Tank Dose with HydroSil Ultra 7.5% for Protection Against Bacteria & Viruses
  3. Undersink <1 Micron Absolute Filter for Protection against Parasites & (Optional) Coconut Carbon for Improved Final Taste & Odour

Read on for a full explanation of why we recommend this as the minimum standard of filtration for treating Rain/Tank/Potable Bore Water for drinking.

For Protection Against Bacteria/Viruses

Bacteria (such as E.Coli) can colonize in the stagnant water and result in harmful illnesses when consumed. For sanitation against common water-borne bacteria/viruses in rainwater and potable bore water*, we, therefore, recommend dosing your tank with a product such as Hydrosil Ultra 7.5% Water Sanitiser to ensure protection against microbiological contamination/biofouling in your pipework and/or filter system.

HydroSil is a food-grade silver-activated, hydrogen-peroxide based water sanitiser, which acts to oxidise bacteria, yeast, fungi & viruses, without leaving any dangerous residues behind. HydroSil sanitizes and protects your tanks and water storage devices, making rainwater and potable bore water safe and suitable for human consumption. HydroSil is not a chlorine-based chemical like most sterilisers on the market today. It is non-toxic, and safe to use around your home and family.

PLEASE NOTE: REVERSE OSMOSIS SYSTEMS PERFORM OPTIMALLY ON CHLORINATED (MAINS/TOWN) WATER, AS THE PRESENCE OF CHLORINE KILLS THE BACTERIA/FUNGI/YEAST. THEREFORE, REGULAR & CONSISTENT WATER DISINFECTION IS STRONGLY RECOMMENDED FOR RAIN/TANK/POTABLE BORE WATER* SOURCES PRIOR TO USING A REVERSE OSMOSIS FILTER SYSTEM. FAILURE TO ADEQUATELY DISINFECT THE WATER WILL RESULT IN BIOFOULING OF THE RO MEMBRANE (I.E. A BACTERIA/FUNGUS/SLIME COLONY WILL START GROWING INSIDE THE MEMBRANE WHICH WILL PUTREFY YOUR FILTER SYSTEM & RENDER THE RO MEMBRANE UNSALVAGEABLE). 

Dosage Rate: HydroSil should be dosed at a rate of 200mL per 1000L of water. To scale down to tank size, you will require 20mL per 100L.

For Protection Against Parasites/Protozoa

Ingesting waterborne parasites (Protozoan Cysts) such as Cryptosporidium and Giardia (which flourish in raw water sources such as rain water tanks and bores), are a common cause of gastroenteritis. Whilst Chlorine can inactivate Giardia with a moderate dose and contact time, Chlorine has a negligible effect on Cryptosporidium unless dosed in excess of the acceptable Chlorine limit per the Australian Drinking Water Guidelines (Version 3.6, pp. 200).

For protection against these common cysts, we, therefore, recommend under sink filtration down to at least 1 Micron (Absolute) or smaller (i.e. with Reverse Osmosis or the Caware 0.1 Micron Absolute 3-in-1 Sediment, Chemical + Bacteria Reduction Filter). Such fine filtration, used along with regular sanitation (i.e. with HydroSil Ultra 7.5%) is a cost-effective and safe drinking water solution for rain water and potable bore water*, and is perfect for casual disinfection requirements such as when travelling in a caravan.

Why UV Disinfection is NOT Recommended for Travelling/Casual Use

You may have read that Ultraviolet (UV) Disinfection is one of the safest and most effective methods for treating drinking water, as it has a minimal effect on drinking water’s composition and taste, whilst killing 99.9% of microbiological contaminants. It's true that UV is highly effective at inactivating the DNA cells of water-borne micro-organisms such as bacteria and viruses, and is excellent at killing chlorine-resistant parasites such as Giardia and Cryptosporidium.

However, as effective as they are, please note that UV systems are generally NOT recommended for caravanning and casual use, for the following reasons:

  • UV Systems require electrical input and typically need to be left on 24/7 to prevent degradation of the UV lamp (not ideal for infrequent use).
  • UV radiation also heats up the UV chamber and, in some cases, requires a constant flow of fresh water and a thermal release valve to release the hot water (which is not ideal on a small water tank).
  • UV Systems also contain fragile glass components (not ideal for travelling).
