HyPURE® RO Systems

Hydroflux are New Zealand’s most experienced supplier of Industrial wastewater recycling. Enabling our team to design solutions for even the most difficult to treat feed waters.

Some of the main benefits of our system include:

• HyPURE^® systems are individually tailored to suit our customers needs.
• Turnkey solutions with multiple stages, zero liquid discharge applications.
• Multiple passes of HyPURE^® can be coupled with additional polishing stages to produce demineralised and ultrapure water.
• Hygienic solutions designed in house to comply with the most rigorous sanitary design standards.
• Containerised and modular design allows for simple, plug and play installation on site.

Utilisation of Hydroflux HydraSCALE^® best-in-class anti-scalants allows for the HyPURE^® range to achieve the optimum recovery from start-up.

Containerised and modular design allows for simple, plug and play installation on site.

Some of the key features of the HyPURE^® range of brackish RO systems are:

• VSD drives for all high pressure pumps, to optimise energy consumption and plant recovery regardless of variable TDS and temperature conditions
• Robust, cost effective plant design all manufactured to Australian standards
• Advanced instrumentation and monitoring to facilitate forecasting of system maintenance and membrane life
• Remote plant control and troubleshooting support through HyCONNECT^®
• Utilisation of world leading HydraSCALE^® RO anti-scalants to optimise plant performance
• Integration with additional SeaPURE RO, ultra high pressure, disc stack RO and HySEP brine clarification systems for zero liquid discharge applications

Our expertise in wastewater gives us a unique edge in the industry, as we design our systems to manage water sources with the highest risk of scaling and biofouling. This conservative approach leads to extended membrane life, low energy consumption, minimum downtime and maximum recovery.

One of the major challenges providing clean water from seawater to those who most desperately need it is the high energy requirement to desalinate seawater. Hydroflux offer a range of unique energy recovery solutions for small and medium SeaPURE plants, producing as little as 5m 3/D. Our unique design feature ensures Hydroflux provide our customers with the most energy efficient solution available on the market, no matter how big or small their system is.

Some of the key features of the SeaPURE range of seawater include:

• VSD drives for all high pressure pumps, to optimise energy consumption and plant recovery regardless of feed conditions
• Energy Recovery Devices, even on the smallest plants (5m3/D)
• Robust, cost effective plant design all manufactured to Australian standards
• Advanced instrumentation and monitoring to facilitate forecasting of system maintenance and membrane life
• Remote plant control and troubleshooting support through HyCONNECT®
• Utilisation of world leading HydraSCALE® RO anti-scalants to optimise plant performance
• Containerised or modular skid mounted solutions for true plug-and-play installation
• Integration of the SeaPURE plant with a wide range of pre-treatment solutions designed and supplied in-house by Hydroflux®

Hydroflux also offer the SeaPURE range in ultra high pressure RO and disc stack RO.

What is the capacity of the range of HyPURE^® Reverse Osmosis systems?
The HyPURE^® range a individually designed to suit customer requirements, the treatment capacity can range from <5m3/D up to and above 50,000m3/D. We have standard sizes that we manufacture, but due to the variability of the site conditions, feed water quality, available space in the plant each solution must be tailored to suit.

What type of maintenance is required on a HyPURE^® RO?
HyPURE^® RO’s are designed for extended maintenance free operating periods. Typically, only infrequent checking of chemicals, cartridge filter replacement and calibration of probes is necessary, as all critical operating data is continuously recorded and saved to customers HyDATA accounts. Operation of the plant can also be controlled remotely through the HyCONNECT^® system. A routine Clean in Place (CIP) is necessary to maximise membrane life however this process is made very simple by our online step-by-step CIP walkthrough, which minimises operator error in what would be a complex task on traditional RO plants.

HyPURE^® RO’s are designed for extended maintenance free operating periods.

Does the HyPURE^® RO require a lot of power?
Generally speaking, brackish water RO systems require a lot less power than other types of desalination technology. The power is also influenced greatly by the feed TDS, required water quality and operating temperature. That being said, a HyPURE^® RO due to the low energy design requires less power than other RO systems operating in equivalent conditions.

Due to the low energy design, HyPURE^® RO require less power than other RO systems operating in equivalent conditions.

Can the HyPURE^® RO systems handle variable loads of dissolved solids?
The Reverse Osmosis systems variable pollutant loads if the feed pump frequency can be reduced or increased sufficiently to facilitate it. In some applications where the TDS varies so significantly, (e.g. in construction and groundwater remediation) a specially designed pumping system must be included with the system. Hydroflux have experience in specialised RO system capable of handling these fluctuating loads.

Can the HyPURE^® RO system handle suspended or colloidal solids?
Introduction of any suspended or colloidal solids to RO systems should be avoided, as these rapidly foul the RO membranes. If suspended or colloidal solids are present in the feedwater, the upfront use of HyDAF/FlooDAF or HyPURE^® MMF or UF should be considered. The level of pre-treatment required will often depend on suspended solids and or silt density index (SDI) or membrane fouling index (MFI) tests performed on the feed water.

Through our in-depth knowledge of pre-treatment processes, Hydroflux have the required level of expertise to assist our clients to develop an overall water treatment strategy which minimises the total cost of ownership.

Can the HyPURE^® RO system handle iron, manganese and other metals in the feed water?
RO systems, can handle trace levels of metals within the feed water. However, to avoid the formation of metal oxides and metal hydroxides extreme care must be taken to prevent the introduction of dissolved oxygen (through head space in tanks and other areas) to maintain these elements in a reduced state. Quite often this is not practical and a HyPURE^® MMF with Manganese Greensand media, HySEP clarifier or HyDAF/FlooDAF is necessary up front to avoid fouling of the RO system.

For optimum performance a HyPURE^® MMF with Manganese Greensand media can be installed upstream to remove trace metals when necessary.

Do I need any treatment after a HyPURE^® RO system?
In many instances, additional treatment is required even after an RO system. Despite RO permeate being very low in dissolved salts, trace levels of dissolved organic carbon (DOC) provide enough food for slow growth of organisms within the treated water permeate pipe network. Often as a minimum, residual disinfectants such chlorine, chlorine dioxide, chloramine or ozone are introduced. In many instances, hardness and bicarbonate alkalinity is also added into the permeate to protect copper and cast-iron pipe networks from dissolving in RO permeate. Additional post treatment involving UV disinfection, membrane degassing, continuous electro deionization or Ion exchange are also utilised to produce higher purity water levels for specialised industrial processes.

Is it possible to maintain a clean environment in the RO permeate without the use of residual disinfectants?
Yes, this is common in hygienic applications where process water is going into products which can not tolerate chlorine, e.g. semi-conductor/microelectronics, beverages, pharmaceutical products, cosmetics or in the production of nutritional powders. To maintain a hygienic environment in the product pipework free from microorganisms, hygienic grade stainless or other smooth walled materials are required. The pipework must be routinely cleaned, either by high temperatures (up to 85 C) or infrequent chemical washes. Hydroflux design HyPURE^® plants which can be entirely heat sterilised, including the use of sanitary heat sanitisable RO membranes to ensure the complete treatment plant is free from microorganisms. Treated water pipework may also need to be continuously flushed, to prevent growth within pipework dead legs through the implementation of continuous recirculation and polishing of the product water supply loop. The Hydroflux team specialises in the design of hygienic plants.

All projects are conducted under externally approved occupational health and safety, and environmental management systems.
