Flue Gas Desulfurization WASTEWATER
FGD WASTEWATER TREATMENT
Flue Gas Desulfurization (FGD) is a process that can require the use of water to remove sulfur dioxide (SO2) from flue gases produced by burning high sulfur fuels such as coal and oil. Also referred to as Flue Gas Scrubbing (FGS), FGD has been used since the 1960s in large stationary sources of pollution such as power generation plants.
The wastewater generated by Flue Gas Desulfurization is referred to as FGD wastewater (FGD water) or FGD bottom ash with wet scrubbers used to scrub the water of gases.
The result, however, is water high in contaminants and pollutants. The wastewater is often supersaturated with gypsum and is highly acidic with high concentrations of Total Dissolvable Solids (TDS) and Total Suspended Solids (TSS) with chlorides, fluorides, nitrates, nitrites and potentially harmful trace metals.
This water that comes from FGD must go through proper wastewater removal systems prior to discharge. Minetek has the ability to manage FGD wastewater through an innovative, yet simple, and sustainable groundwater management and water evaporation processing with a global network of specialists able to assist in any industrial setting around the world.
We have placed some difficult demands upon MINETEK. These demands are never an issue, and are met with the enthusiasm and professionalism we have grown to expect from the MINETEK team.
We have utilised MINETEK for a number of sound attenuation projects in the Hunter Valley and have formed an excellent relationship with Glencore over many years. MINETEK understand our industry and always provide a solid and professional commitment to meeting our goals and objectives."
MINETEK will continue to be a favoured technical resource and supplier to the New Hope Group and are recommended as a professional, respected and competent supplier of technical services, equipment and products for noise abatement and other industrial products.
After investigating a raft of different methods from sprinkler systems through to desalination systems (too costly for little benefit) we decided on the MINETEK WATER units. The evaporators were easy to install and once activated ran trouble free. We were very happy with the service from MINETEK and the reliability of the system.
I have used these evaporators very successfully at mine sites where I have worked in the past. They are an extremely reliable unit and worked above expectations in the environment where we had them set up. As for spray drift/mist this can be controlled by the weather monitoring systems that are available with the units. Additionally, how you set them up and the amount of fall you can achieve allows for more moisture to be stripped from the droplets]will greatly benefit your overall evaporation rates.
