Water Treatment

WPM Green Energy offers custom made water and wastewater treatment energy saving technology solutions, bringing significant benefits and competitive advantages in building high performance desalination and water treatment plants.

In the field of Water Treatment WPM Green Energy partners with GrahamTek Systems – global experts in 16 in Reverse Osmosis technology, which offers significant benefits and competitive advantages in building high performance desalination and water treatment plants. They were the first to invent, patent and install and operate the 16" RO technology. They are not only technology suppliers but also project financiers with a key strategy of BOO/BOOT project implementation.

Our new energy saving technology solutions offer low energy consumption plant operations and is being used in some of the biggest desalination plants in the world, producing in excess of 1 billion litres a day.

16” RO plants offer significant commercial advantages over other RO technologies and as the inventor of the original 16" technology, GrahamTek Systems has unparalleled know-how and expertise to design and build water treatment plants of the highest performance standards.

Our technology covers a wide range of Water Treatment solutions, from the Feed Water intake (post Pre-Filtration) point to the Bulk Product Water Distribution Point:
• Large Industries: Mining, Oil & Gas and Food & Beverage
• Quasi-Government Organisations: Harbours and Ports
• Public Sector Infrastructure: Waste Water Treatment Facilities, Bulk Water Supply from Desalination facilities
• Emergency Relief: Mobile units that can provide immediate relief to communities of up to 5,000 persons in remote disaster or emergency location
We believe that by addressing the needs of larger organisations we can maintain the economic drivers of the country and relieve pressure on government infrastructure that is required to serve the population.

Own Intellectual Property

As inventor of the original global 16" Reverse Osmosis (RO) technology, GrahamTek has subsequently registered patents for several unique RO components and therefore uses many of these designs in our 16” RO vessels to capitalise on the design of a larger RO vessels and create a full turnkey solution for our clients. The 16” plant designs can reduce the footprint of water treatment facilities by up to 40% when compared to standard 8” designs.

Increased Membrane Life

Using a new specialised Cleaning In Place (CIP) process unique to the 16” RO vessels, we are able to reduce the negative effect of CIP and extend the life of the Membrane. The process is linked to the remote maintenance management system and uses an automated intermittent forward-reverse water flow process to remove solids from the membrane at predetermined flux levels. It requires our electronic management system to be included in the system design, which further reduces damage to the treatment plant due to operator errors.

Remote Management Technology

Our wireless Management System takes advantage of the latest sensor technologies and enables us and our client to remotely operate the system and monitor critical parameters, thus ensuring a continuous water product quality and water demand matching. The system enables the client to optimise energy use and electricity cost while operating the system according to specific operational goals. It implements decision support tools for predictive and pre-emptive maintenance modelling. The software technology utilises open architecture that enables the integration with other software management systems. The open architecture ensures that the client is not locked into a single supplier of Water Treatment solutions.

Environmental Impact Assessment

Our product range has been extensively tested and monitored in very sensitive ecological locations. Comprehensive independent reports give clear guidelines on the use of the system, cleaning of membranes and the effect of these processes on the marine bioregion. These reports assessed the water intake and discharge wells and made specific recommendations in the event of the system not operating as specified.
The conclusion of these reports indicate that the overall effect of our product solution on the marine bioregions is negligible. We are therefore confident to use these reports in location and site specific areas to ensure that our systems maintain and support a sound ecological balance.

Non-Disruptive Maintenance

Not only does the sophisticated management system provide for a predictive maintenance programme but our Modular design principle allows for a bulk water supply plant to be maintained without complete disruption to the provision of Water Product. The design allows for any one of a number of modules to be shut down or temporally removed from the supply or source while the other modules maintain the production loads to supply the product requirement. This design principle protects water authorities and downstream equipment that rely on the constant water supply.

Technology Innovation

GrahamTek is in the process of incorporating new technologies into its water treatment systems to provide integrated low energy peak performance water treatment solutions. It has combined two new technologies along with proprietary Waste to Energy technology and our advanced 16” Superflux® RO technology to design and build new level high performance, energy efficient water plants.

This technology innovation uses waste brine discharge from sea water desalination to produce electricity. This significantly reduces the cost of water production by taking the water plants off the grid due to their power self-sufficiency. Furthermore, with this new technology yields are increased, reducing the per litre OPEX even further.

This synergistic technology will offer a total solution to AMD water treatment whereby previously unusable polluted water is converted into steam to create electricity through the steam turbines. Excess steam is then condensed and processed through our filtration systems to create water for reuse, thus increasing yields and achieving Zero Liquid Discharge (ZLD). Excess power generated may also be sold back into the grid, rendering these water plants not only power sufficient, but having a negative power consumption.
