WATER MANAGEMENT
This family of products includes a comprehensive suite of strong and weak acid cation exchange resins, and strong and weak base anion exchange resins for use in both packed bed and layered bed systems. Different combinations will result in various levels of efficiencies. The line-up allows operators to use the best combination of resins with their vessel type to achieve extremely low unit cost of demineralised water, high regenerability, and reduced waste volume.
Other features of the product family include solutions that help operators minimise corrosion, protect equipment and reduce scaling and operational downtime.
“ With the next generation DOWEX MARATHON product family, customers are getting the best product design and the highest quality and performance we can offer to the industrial water treatment and fossil power industry,” says Marlin Kinzey, Global Marketing Director for Ion Exchange, DW & PS.“ By consolidating and building our offering under this new line, we ' ve optimised the solutions and help to deliver a step-up in operational benefits for our customers.”
Water filtration
Ultra filtration( UF) and nanofiltration membranes have come a long way as solutions for water treatment, reports I-CAT. A significant amount of research and development goes into improving these technologies. Most recently, mechanical evaporation systems, which ensure effective and environmentally safe reduction in excess wastewater for mining, have also come to the forefront of water management.
I-CAT Director of Business Development and Marketing, Lourens Jansen van Rensburg, reports that his company has been awarded several contracts to monitor, manage and recycle water at several mining groups over the years.“ Our methods are preferred because we do not believe in using or adding chemicals to wastewater to purify it or to get it to discharge standard. We make mechanical purification systems and have an excellent technical and design team that is focused on innovation and coming up with solutions for challenging projects.”
According to van Rensburg, I-CAT Environmental Solutions uses a combination of technologies to provide its clients with the best and most cost effective solutions, while maintaining a consistent awareness of the environment, energy and social demands.“ Our filtration systems are cost effective, as they have no recurring chemical costs, require low maintenance and are self-cleaning. The technology we use is considered world-leading, affordable and effective. We have developed solutions to clean process water where many older technologies and processes have failed.”
Ulan Coal Mines’ complex operating near Mudgee in NSW, Australia, has both underground and open-pit operations. This requires the extraction of large volumes of water. The on-site water treatment facilities need to be able to produce sufficient permeate to blend with other on-site waters to generate up to 30 million litres / d of blended water of suitable quality for environmental river discharge.
A reverse osmosis( RO) plant and UF pretreatment system provided by Osmoflo currently treat water from East Pit, which is a large capacity surface dam. This enables the water to be recycled back into the ecosystem along with on-site irrigation.
Water requiring treatment includes water that has been accumulated on-site( East Pit) and water pumped from underground and open cut mine workings, as well as surface run-off from rainfall that makes its way to East Pit from the site catchment. The mine water, including that from East Pit, is generally very high in dissolved manganese( approximately 3 mg / litre). Some raw water streams from individual pump stations can exhibit manganese levels significantly above 3 mg / litre.( e. g. pump station E20 generates mine water containing approximately 9 mg / litre of manganese). High manganese concentrations similar to iron have a tendency to foul up UF and reverse osmosis systems with a black sludge that can restrict the flow and performance.
