300 GPD Reverse Osmosis (RO) system -Click For More Info

Small Semi- commercial direct line RO system with a production capacity of 1200 Litres Per Day / 50 Litres Per Hour

300 GPD Reverse Osmosis (RO) Direct Line

  • The 300 GPD RO system has a maximum production capacity of 1200 Litres per Day / 45 - 50 Litres Per Hour.  
  • The RO system will remove 99.8% of contaminants from water including rust, dirt, sand, mud, chlorine, organic molecules, chemicals, pesticides, herbicides, heavy metals, bacteria, viruses and parasites. 
  • As the membrane captures contaminants in the water they begin to build up on the membrane’s surface, and so to prevent the contaminants from blocking or damaging the membrane the system is constantly flushing the membrane as the system runs. This constant flushing by the system leads to water wastage, as the water used to flush the membrane goes straight down the drain. The water wastage ratio is about 4:1, which means that for every 1 litre of clean water produced there is 4 litres that is used to flush the membrane.  
  • Keep in mind that the RO system is also removing minerals from the water, leaving you with clean water that has little to no mineral content.
  • The 300 GPD RO does not come standard with a storage tank.

  •  Please note that filter life spans are based on municipal quality source water.
  • RO Membrane life span is dependent on the pre-filters being correctly maintained, failure to do so will result in a diminished life span of the membrane. 

 

Additional Options: 

Mineral Injector:

The mineral injector helps to replace some of the minerals lost during the Reverse Osmosis (RO) process. The Mineral injector is filled with small beads of mineral, as the water passes through the mineral injector small amounts of minerals breaks away from the beads and are carried with the water. Our mineral injectors inserts traces of potassium, calcium, magnesium, germanium and iron.

  • Potassium: Potassium is vitally important for the functioning of all the cells in the body, especially in the maintenance of neurons (nerve and brain cell). It is also an essential micro nutrient that - together with sodium, chlorine, magnesium and calcium - plays an important roll in maintaining the body's electrolyte balance.
  • Calcium: All the muscles, bones and cells in the body require calcium to function. Calcium is also needed to facilitate the growth and maintenance of healthy bones and teeth.
  • Magnesium: Magnesium improves the function of the mucles, heart and kidneys, by promoting the circulation of blood in the body. It helps to strengthen bones and teeth.
  • Germanium: Germanium is a plant-based mineral that has the property of being toxic to bacteria, but harmless to humans and animals. When ingested, it has also been found to stimulate metabolism of the body. It also has the ability to absorb heavy metals and impurities from water.
  • Iron: Iron is one of the main components of hemoglobin, the substance that enables your red blood cells to transport oxygen around your body. It is also part of myoglobin, which enables mucles to store oxygen that is used for cellular respiration.
  • The Mineral injector has a life span of 12 months (1 Year) and then it will need to be raplaced.

 

Pressure Reducing Valve:

The system and its housings are rated for a maximum pressure of 6 bars, higher than that and the housing will crack or "bulge". If you have very high water pressure or you know that your source pressure is prone to sudden pressure spikes then it is strongly recommend that you get a pressure reducing valve. 

The Pressure reducing valve will keep the incoming pressure from exceeding 6 bar and so prevent the unit from being damaged.

Leak Detector:

The Leak detector is installed on to the under the counter unit, and serves to protect against damage that may be cause by any leakage of the filter system.

The leak detector will cut off the source water if there are any leaks coming from the main unit.

Keep in mind that the leak detector will not stop leaks from the unit's source connector and faucet.

Premium KDF instead of Carbon filters:

Changing the Carbon filters for Premium KDF filters will change the maintenance of the Carbon filters to every 24 months, thus only the 1st and the 5th filter will need to be changed every 6 months.

If you have bacteria in your source water:

If the bacteria builds up in the system, it will result in biofouling of the membrane, this will then result in getting worse water out of the filter system than you actually had before. Therefore we highly recommend changing the system into a double barrier system if you suspect that you have bacteria in your source water. This can be done by replacing the second filter (GAC) with a Premium KDF that will prevent a build up of bacteria in the filter. We then add a pysical barrier to bacteria by replacing the third filter (The Carbon Block) with a Ultra Filtration Cartridge. This filter will need to be changed once a year but will greatly improve the systems ability to handle contaminated source water at a fraction of the cost of a custom small industrial system.

 

 Ultra Violet (UV) Light Filter:

The RO membrane will remove bacteria and viruses from the water, however once the water has passed the RO membrane, there is nothing to stop any bacteria that may be inside the tank, or could possibly find their way in to the piping after the RO membrane. So for additional peace of mind that all the bacteria and viruses have been removed, you can have a Ultra Violet (UV) Light filter added to the RO system. The UV light would be just before the tap, and would just ensure that any bacteria or viruses that may have entered after the RO membrane are killed. The 10 Watt stainless Steel UV light with its own power source.

  • The UV light's Bulb has a life span of One Year.
  • Keep in mind that the UV light addition will require an electrical source in order to operate.
  • The 10 watt UV Bulb would be R 450.00 to replace.

Storage Tank:

The 300 GPD RO does not come with a storage tank, like the smaller domestic units. However, you can add a storage tank to the system, which will then create a buffer of Filter water to draw from. This means that at any given time there is 6 to 500 Litres of pre-filtered water, depending on the size of the storage tank selected.

Mixed Bed Resin Cartridge:

The mixed bed resin cartridge is installed after the RO membrane, and helps to further reduce the Total Dissolved Solids (TDS) or Mineral content in the product water. This is ideal for situations which require a low mineral content water or little to no conductivity in the product water.

Keep in mind that the final level of TDS in the product water will depend on the quality of source water, additional Mixed bed resin cartridges can be added later on to further reduce the mineral content. The life span of the mixed bed resin cartridge will also be completed dependent on the quality of the source water and level of TDS coming from the Membrane.

Situations that normally require a low mineral content water include:

  • Aquariums
  • Chroming
  • Labratory equipment
  • Batteries

Inline Water Chiller:

The Inline Water Chiller provides up to 12 LPH of water at under 10oc. This is ideal for an entertainment area or a situation where the water is too hot coming from the filter system.

Water Alkalizer:

One of the more complicated things to change and manage in water is pH. Our bodies want to maintain a pH of 7.8. So if we consume food or drink with a lower pH such as something very acidic (pH less than 7 is an acid) like a sparkling cold drink we have to use some of our reserves of calcium from our bones to maintain a steady pH level. 

Water in general isn't one of the major contributors as normally water has a very low buffer. Buffer is how easily the solutions pH is changed. However water is very often a relatively low pH such as 5 due to CO2 from the atmosphere being absorbed. 

The water alkalizer aims to address this problem by slowly dissolving minerals into the water that acts as a buffer and increases the pH. It will vary with flow rate but the aim is to get Reverse Osmosis (RO) water to a pH of over 8. This will eliminate the contribution of water to an acidic diet as the water will now be alkaline.

Chilling and Heating options

Are you looking to have your filtered water chilled and heated then there are several options avaliable:

Plumbed in water dispenser

We have several variations of plumbed in water dispensers available, all of which can be connected directly up to the filter system allowing you to chill and heat the filtered water. 

Ideal for office, commercial and domestic situations. 

You can find more information on the plumbed in water dispensers at the following link.
