Technologies & Processes
Water treatment systems are typically delivered through a combination of technologies applied in sequence to achieve defined water quality and compliance outcomes. Configuration varies based on source water, application, and operational requirements. Selecting the appropriate treatment approach requires technical expertise, regional knowledge, and an understanding of industry‑specific performance and regulatory needs.
Filtration
Bag & Cartridge
Bag and cartridge filtration provides a flexible solution for removing suspended solids and particulate contaminants. Available in a wide range of micron ratings, these filters are used to manage everything from coarse sediment through to fine particulate matter.
They are commonly applied across municipal, commercial, and industrial environments, including mains water filtration, rainwater harvesting systems, and as pretreatment upstream of technologies such as reverse osmosis. Their role is to protect downstream equipment and maintain consistent system performance.
Multimedia
Multimedia filtration utilises layered filter media — such as sand, anthracite, and garnet — arranged in a defined sequence to remove a broad range of suspended particles.
This approach supports the effective removal of sediment, organic matter, and other particulate contaminants, making it suitable for applications requiring higher filtration capacity or variable influent water quality.
Screen Filtration
Screen filtration is often applied as a first‑stage protective measure, using fine mesh screens to remove larger particles, debris, and some biological matter.
Widely used across industries such as pharmaceuticals, food and beverage, and power generation, screen filters are applied at intake points, for seawater pre‑treatment in desalination, and to protect sensitive downstream equipment.
More recently, screen filtration has been adopted in commercial applications including mains inlet filtration and rainwater harvesting, where benefits such as continuous flow, compact installation, low pressure loss, and minimal backwash water consumption are valued.
Reverse Osmosis
Reverse osmosis (RO) is an advanced membrane‑based treatment process used to remove dissolved salts, minerals, microorganisms, and chemical contaminants.
By applying pressure to force water through a semi‑permeable membrane, RO systems deliver high‑purity water suited to applications with stringent quality requirements. System design is tailored based on industry, application, and compliance criteria to ensure reliable and efficient operation.
Treatment
UV
Ultraviolet (UV) disinfection is used to inactivate microorganisms such as bacteria, viruses, and parasites by disrupting their DNA or RNA, preventing replication.
As a chemical‑free treatment method, UV is widely applied where microbial control is critical and water chemistry must remain unchanged. It provides rapid treatment, minimal maintenance requirements, and does not affect taste or odour, making it suitable for potable, healthcare, and process water applications.
Multimedia
Multimedia treatment systems utilise layered media arrangements to manage particulate and organic loading within treatment processes.
Configured to suit specific applications, these systems support consistent water quality outcomes and can be integrated with other treatment technologies as part of a broader treatment train.
