ISBRAE Water Filtration Systems

ISBRAE Filtration Technology

Filtration designed
around your water.

Different filtration technologies serve different purposes. Explore each system to understand how it works and where it fits within a modern water filtration system.

RO Filtration Technology

Reverse Osmosis (RO)
Water Filtration

Reverse osmosis uses a fine membrane to provide deep filtration of dissolved substances, making it suitable for applications where a higher level of purification is desired.

RO is commonly used in under-sink drinking water systems where purified water quality and consistent filtration performance are key considerations.

How It Works

Fine membrane filtration
Reduces dissolved substances
Multi-stage water treatment

Suitable For

Under-sink systems
Drinking water applications
High-purity water requirements

Reverse Osmosis

UF Filtration Technology

Ultrafiltration (UF)
Water Filtration

Ultrafiltration uses a membrane to help remove fine suspended particles and microorganisms while allowing naturally occurring dissolved minerals to remain in the water.

UF is suitable where effective physical filtration is desired without removing the naturally occurring dissolved mineral content of the incoming water.

How It Works

Membrane-based filtration
Filters fine suspended particles
Retains dissolved minerals

Suitable For

Point-of-use filtration
Mineral-retaining applications
Everyday drinking water

Ultrafiltration

NF Filtration Technology

Nanofiltration (NF)
Water Filtration

Nanofiltration provides selective membrane filtration and sits between ultrafiltration and reverse osmosis in terms of filtration characteristics.

It can be used where targeted reduction of selected dissolved substances and water hardness is desired while maintaining a more balanced water profile.

How It Works

Selective membrane filtration
Targets selected dissolved substances
Helps reduce water hardness

Suitable For

Balanced filtration
Point-of-use systems
Selective mineral reduction

Nanofiltration

Carbon Filtration Technology

Activated Carbon
Water Filtration

Activated carbon uses adsorption to help reduce chlorine, unwanted tastes, odours and selected organic compounds that can affect the drinking water experience.

Carbon filtration is commonly integrated into multi-stage systems and can serve as either a primary or complementary filtration stage.

Helps Reduce

Chlorine
Unwanted taste
Unwanted odour

Suitable For

Taste improvement
Multi-stage filtration
Everyday drinking water

Activated Carbon

PP Filtration Technology

PP Sediment
Water Filtration

PP sediment filtration is commonly used as the first stage of a multi-stage filtration system to capture larger suspended particles before water reaches finer filtration stages.

Reducing sediment at the beginning of the filtration process can also help protect subsequent filter media and membrane components.

Helps Capture

Sediment
Sand and suspended particles
Visible particulate matter

System Role

Pre-filtration
Protects downstream filters

Mineralization Technology

Mineralization
Water Treatment

Mineralization is a post-treatment process that may be used after deep filtration to adjust the mineral profile of purified water.

Depending on the system configuration, a mineralization stage can form part of the final refinement process before water reaches the drinking water outlet.

System Role

Post-treatment stage
Water profile adjustment
Final water refinement

Suitable For

Post-RO configurations
Multi-stage systems
Final treatment applications
