Filtration Process
We utilise different filtration and treatment processes based on the individual circumstances of each customer.
Water Filtration Systems
Water filtration removes impurities and contaminants from water using a range of filtration and treatment technologies.
Freshwater Systems offers water treatment solutions for homes, small businesses and caravans, including:
- Under-sink filtration – clean, filtered water at a dedicated drinking outlet.
- Whole-house filtration – filtration for your entire home.
- Water softening – reduces hard-water minerals such as calcium and magnesium.
- Reverse osmosis (RO) – membrane filtration that can remove up to 98% of many contaminants.
- Water disinfection – including ultraviolet (UV) treatment.
- pH and remineralisation – treatment to modify water properties.
Common Filtration Methods
Particle filtration – removes sediment and suspended particles using pleated or poly-spun filters.
Carbon filtration – reduces chlorine, chloramine, chemicals, taste and odour, improving water quality and palatability.
Membrane filtration – reverse osmosis uses a fine membrane to remove a wide range of dissolved contaminants.
Ion exchange – used in water softening to reduce hard-water minerals.
pH modification – adjusts the alkalinity of water for specific applications.
Carbon Filtration
Carbon filtration is commonly used to reduce chlorine, chloramine, tannins, chemicals and fine particles, helping improve the taste, smell and clarity of water.
Carbon filtration is used across many Freshwater Systems, including drinking water systems, twin filtration systems, reverse osmosis systems and whole-house filtration.
Choosing the right treatment depends on your water source, water quality and intended use.

Reverse Osmosis (RO) Water Filtration
Provide high-quality filtered water for homes, offices, small businesses and industrial applications. RO systems are compact, reliable and easy to maintain. They are ideal for drinking water and can also be used to treat rainwater and other water sources.
What is Reverse Osmosis?
Reverse osmosis uses a semi-permeable membrane to remove dissolved impurities and contaminants from water.
RO filtration can reduce dissolved salts and minerals, fluoride, PFAS, heavy metals such as lead, pesticides and herbicides, Volatile Organic Compounds (VOCs), bacteria and other microorganisms, Total Dissolved Solids (TDS).
The result is high-purity water with improved taste and quality.
Customise Your Water
RO provides a clean base for further treatment. Additional filtration can be added to remineralise water, adjust pH or tailor the water to specific applications.
Freshwater Systems can help you select the right RO system and filtration combination for your water source and requirements.
Ultrafiltration Water Filtration
Freshwater Systems Ultrafiltration (UF) systems provide advanced water filtration for homes, offices, small businesses and community applications. UF is ideal for treating alternative water sources such as rainwater, river, creek, dam and bore water, providing cleaner water for whole-home use.
What Does Ultrafiltration Remove?
UF membranes filter out contaminants including Bacteria, Viruses, Suspended Solids, Colloids, Organic Matter & other impurities
Unlike some treatment methods, UF does not remove beneficial minerals and salts from the water.
Why Choose Ultrafiltration?
- Advanced membrane filtration
- Suitable for challenging water sources
- Ideal for whole-house water supply
- No chemical disinfection required
- Low ongoing maintenance
- Efficient and reliable

UV & LED Disinfection
Rainwater, river water and bore water can contain bacteria, viruses and other microorganisms that may make water unsafe for drinking or household use. UV and LED disinfection provide effective, chemical-free treatment to help make water safer for use.
Alternative water sources can be used as a supplementary or primary household water supply, helping reduce reliance on mains water and water costs. Common sources include rainwater, river water and bore water.
Why Disinfect Alternative Water?
Water from rainwater tanks, bores, rivers and other untreated sources can contain microorganisms and pathogens. Disinfection is particularly important when water is intended for drinking, cooking or other household uses.
Freshwater Systems offers water treatment solutions designed to suit different water sources and applications.
UV & LED Water Disinfection
UV (ultraviolet) disinfection uses UV light to inactivate microorganisms including bacteria, viruses, yeasts and fungi. It is commonly used as the final stage of treatment in whole-house water filtration systems.
LED disinfection provides a compact, durable and efficient alternative for lower-flow applications, such as under-sink drinking water systems.
For UV or LED treatment to work effectively, water should be appropriately filtered beforehand and pass through the system at the specified flow rate.
Choosing the Right System
The right treatment depends on your water source, water quality, intended use and required flow rate.
Freshwater Systems can provide solutions for rainwater, bore water and river water, from under-sink drinking water systems through to whole-house filtration and disinfection.
Water Softening Systems
Water softening reduces calcium and magnesium, the minerals responsible for hard water and limescale. Using an ion-exchange process, water softening resin exchanges these minerals for sodium ions, helping create softer water.
Water softeners can be used in whole-house and under-sink applications, depending on your water quality and requirements.
Benefits of Softer Water
Soft water can help reduce:
- Limescale and mineral build-up on taps, showerheads, pipes, hot water systems and glassware
- Soap scum and detergent residue in bathrooms and washing machines
- Dry-feeling skin and hair associated with hard water
- Detergent and cleaning product use, as less may be required for some cleaning applications
- Maintenance caused by scale build-up in household plumbing and appliances
Find the Right Water Softener
The right water softening system depends on your water hardness, household water use and application.

pH Correction Water Filtration
Water pH can vary depending on its source and composition. pH correction filtration can be used to increase the alkalinity of water and bring low-pH water closer to a desired range.
How does pH Correction Work?
A pH neutralising filter passes water through natural alkaline media, such as calcium carbonate or magnesium oxide. As the water passes through the media, minerals are released into the water to help increase its pH.
These systems are available as under-sink drinking water filters or whole-house filtration solutions, depending on your water quality and requirements.
pH Solutions
Freshwater Systems offers pH neutralising options including:
- Ecosoft Pure Balance 6-Stage Reverse Osmosis System
- Ecosoft Pure Balance Filter
- Calcium carbonate media for integration into selected whole-house filtration systems
The right solution depends on your water source, existing water quality and desired application. Contact Freshwater Systems for advice on selecting the appropriate system.
Water Remineralisation
Reverse osmosis (RO) filtration produces highly purified water by removing a wide range of dissolved contaminants. Remineralisation can be added after RO filtration to restore minerals such as calcium and magnesium.
Adding minerals can also improve the taste and character of highly purified water, creating a more balanced drinking water experience.
How Does Remineralisation Work?
A remineralisation filter adds selected minerals back into filtered water as it passes through the system. This is commonly used as the final stage of a reverse osmosis drinking water system.
Freshwater Systems Remineralisation
Freshwater Systems offers RO systems with integrated remineralisation, as well as remineralisation filters that can be added to suitable under-sink filtration systems.
