WATER TREATMENT FILTERS & SYSTEMS
Municipal water treatment systems in the Garden Route preferably requires the use of physical filtration, activated carbon and redox reaction media treatment. We however will not recommend the use of Reverse Osmosis technology to treat municipal water primarily due to this technology’s water wastage problem.
However, should your municipal water supply be compromised as a result of chemical (e.g. brackish taste, high turbidity, etc.) or biological contamination (e.g. presence of Coliforms / E.Coli) the use of Reverse Osmosis technology, ultraviolet sterilization or ultrafiltration can be considered, but within limits. Please contact us for more information.
Systems can be classified as either point-of-entry (POE) or point-of-use (POU) systems. POE systems treats water for the whole house, or a majority of the house, while POU treats water for a single tap or multiple taps, but not a majority of the house. From a health perspective, we recommend the use of both a POU and POE system. As a start, we will recommend to first install a POU system followed by a POE system.
WATER TREATMENT SYSTEMS
Countertop units are easy to install and are ideal for customers that prefer a portable water purifier for household use or during holidays away from home. These units do not require any permanent changes to plumbing fixtures and a wide variety of replaceable 10” water filters are available.
Undercounter water filters are either installed with a separate smaller faucet, whereas high-flow models can be installed inline, e.g. on your mixing bowl water supply. Water filters with separate faucets require permanent changes to plumbing fixtures, whereas direct inline systems does not. Direct inline water purifiers are becoming more popular due to its high water flow and increased filtration capacity. Technological advances has also resulted in more compact systems that produce great tasting, purified mineral water.
Inline or build-in fridge filters were historically limited to a combination of sediment and carbon filtration. As a results, 6-monthly replacement intervals were required primarily due to the relationship between carbon and bacteria. Redox technology, such as KDF and Active ceramics, allowed the introduction of bacteriostatic filter systems that will also increase the lifespan of these filters.
The presence of fine sediment and/or elevated levels of tannins in municipal water, especially during the rainy season, can result in staining of laundry.
Fine sediment levels can be significantly reduced by 1micron barrier filtration, whereas tannin levels may only be reduced with 0.5micron barrier filtration. A standard washing machine filter comprises of an inline 10” high flow unit, but single Big Blue units can also be used to significantly reduce fine sediment levels entering your property.
Note: these units are designed to only reduce fine sediment levels.
Typical point of entry systems were designed to primarily reduce turbidity (e.g high sediment levels) and chlorine levels in municipal water supply. Entry level systems include 10” and 20” single or double Big Blue systems.
Pleated, spun-wound and melt blown filters are typically used to reduce turbidity levels, whereas Granular Activated Carbon and Carbon block technology are used to reduce chlorine levels. KDF55/GAC technology also enabled the introduction of whole house water purification systems.
Recent technological advances resulted in the introduction of, for example, low maintenance Activated Filter Media, to reduce maintenance cost over time and eliminate human error, as well as the introduction of FRP pressure vessels in various size for larger applications.
We here at Blue Water Solutions know you invested heavily in your commercial equipment, and optimal performance of your assets is crucial in achieving maximum results for your business. Coffee Machines, Ice Machines and Boilers are the most widely treated appliances.
Blue Water Solutions have a wide variety of appliance filters for the
commercial market available. This covers sectors such as the Food & beverage, Cleaning and Manufacturing industries. Our preferred product range for this sector is the iXWATER systems.
The following are most important factors that would need addressing
when buying an appliance filter for commercial use:
- Sediment and fine suspended solids that cause discoloration. This can affect the laundry and cleaning systems, food processes etc. and the results achieved.
- Active chlorine, and numerous inorganic impurities can influence taste and odour in water significantly that also poses health threats.
- Slightly elevated hardness contribute to scaling of food & beverage systems, directly affecting the appliance performance and longevity of its components. Boilers, coffee machines and ice machines are especially prone to this. Clogging of pipes and elements will affect incoming pressure supply and cause an increase energy costs and efficiency.
- Biological contamination of water used in the food processes have a real and tangible health risk on the end consumer, and should at all costs be treated and avoided.
- Blue Water Solutions have a solution for every application, and every requirement should be assessed on its merits and advised accordingly. Please contact us today for a complimentary site assessment to discuss your requirements.

The most important aspects to consider when selecting a water treatment system for non-municipal water supplies such as borehole and rainwater are as follow:
Rainwater treatment systems are the least complicated and the focus should be on preventing and eliminating biological contamination.
Borehole water treatment systems, on the other hand, can be very complicated as no two boreholes have the same water quality. The following three basic steps are of utmost importance to follow:
Collect a water sample and send to a reputable laboratory for a complete chemical and biological analysis.
Locate an expert to interpret the results in order to identify the required water treatment steps.
Decide on the final water use, e.g. human consumption, and water volume requirements per day/week.
WATER TREATMENT SYSTEMS
The key risk with rainwater treatment is biological contamination. The dynamic of rainwater harvesting and its catchment system exposes the application to accelerated risk of biological contamination. The natural low pH of rainwater also pose future health risks that can be easily avoided.
Typical rainwater treatment would entail micro filtration to remove sand and dirt, ultrafiltration to eliminate bacteria and reduce water borne viruses and carbon treatment to improve of colour, taste and odour.
Extra processes such as a pH Fix step to ensure more alkaline water and ultra violet disinfectant to combat biological growth in a hygienic, non-chemical application can also be considered.
The following basic treatment steps are recommended:
Collect and Store
Rainwater storage solutions are easy to achieve for your house, farm or business
Remove dirt and algae
Leaf traps/catcher installed on rainwater downpipes followed by 5 to 1 micron sediment filtration to remove algae, bio-debris, silt, sand, rust flakes and other larger particles.
Remove bacteria and some viruses
Ultrafiltration to remove infectious microbes such as bacteria and protozoa. Ultrafiltration also has a higher removal of microorganisms, especially some viruses.
The recommended minimum pH limit of water for use in the home is 7.0. Normal rainwater has a pH of between 5.6 and 5.8 therefore considered to be acidic.
Destroy all viruses and bacteria – OPTIONAL
Ultra violet sterilisation is a natural and non-chemical way to permanently alters the DNA of these organisms. The organisms are “inactivated” and rendered unable to reproduce or infect.
The ongoing drought conditions in South Africa have resulted in innovative rainwater storage tank designs, ranging from purpose build underground water storage tanks to a series of above ground storage tanks. Storage capacity may vary based on individual needs, but is typically in the order of 20,000lt to 60,000lt for residential use.
Water treatment requirements for both municipal and rainwater sources requires careful consideration as some municipal water treatment media will not be suitable for rainwater treatment. Also, the desired end water quality and plumbing limitations, for existing houses, will also impact the use of or combination of point of entry (whole house type systems) and point of use (undercounter type systems) water treatment.
Boreholes have become a popular alternative water source for many South Africans, especially after some regions were severely drought stricken over recent years. Unfortunately it’s not possible to pre-determine the quality of water you will yield, most often resulting in specialized treatment measures to be applied. The biggest mistake causing failures in the end-usage is the application of generic filtration systems, without knowledge of what areas needs to be addressed. (A bit like shooting in the dark and you hope you hit target!)
Blue Water Solutions has a pre-requisite that a chemical and biological water analysis must either be available, or be obtained in order to advise on specialized treatment. BWS can facilitate this process with you to ensure guidance every step of the way.
