Technology Overview

"GrahamTek Creates, Demonstrates and Proves Technologies…” 

Category of Technology

The GrahamTek 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. GrahamTek focuses on the following Water Treatment solutions:

  • 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

William Graham, the Executive Chairman and founder of GrahamTek, is the inventor of the original global 16" Reverse Osmosis (RO) technology, and subsequently he has registered patents for several unique RO components. GrahamTek 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. GrahamTek 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 GrahamTek 16” RO vessels, GrahamTek is 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 the electronic management system of GrahamTek to be included in the system design, which further reduces damage to the treatment plant due to operator errors. 

Remote Management Technology

The GrahamTek wireless Management System takes advantage of the latest sensor technologies and enables GrahamTek and its 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

The GrahamTek product range has been extensively tested and monitored in very sensitive ecological locations. Comprehensive independent reports give clear guidelines on the use of the GrahamTek 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 GrahamTek system not operating as specified. 

The conclusion of these reports indicate that the overall effect of the GrahamTek product solution on the marine bioregions is negligible. GrahamTek is therefore confident to use these reports in location and site specific areas to ensure that the GrahamTek 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 the GrahamTek 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 down stream equipment that rely on the constant water supply.
