Treatment of wastewater to protect the environment.
If not adequately treated, high levels of nitrate in water can have a significant environmental impact
One of the principal contaminants that must be treated in landfill leachate, and in waste water in general, is ammonia. Ammonia-N in normally present in waste water or in leachate in several forms.
Treatment is therefore essential.
REMOVAL OF AMMONIA
a technological approach
In the execution of any project for the removal of ammonia, Organics employs technology specifically developed for the treatment of large amounts of contaminated leachate. However, our ammonia treatment systems can be adapted to any scale or chemical loading.
Generating New Ideas to Solve Big Problems
Generating ideas takes a lot of brain power and a lot of coffee. The objective is to ensure that our clients are satisfied with the result for a long, long time.
Cups Of Coffee
a unique approach to an age-old problem
Thermally-driven ammonia stripping was developed by Organics to offer an alternative route to that of pH adjustment for continuous-process ammonia stripping.
With a thermally-driven stripper no chemical additions are required, apart from the minor addition of anti-foam agent. The single important input is waste-heat with which to drive the chemical reactions.
If waste-heat is not available, the fuel-cost can be as prohibitive as that of chemical additions or carbon source requirements. Where waste-heat is available, from an engine-exhaust or unwanted biogas, the long-term operating cost can be confined to plant operation and maintenance, including electricity costs.
The preferred option within the Organics process is to use the feed ammonia-laden air directly into the combustion air in the heat-raising process. By this means ammonia gas is destroyed as a part of the process of thermally powering the system.
knowledge and experience
Over the years Organics has installed several leachate treatment plant. These are still operating long after installation. We pride ourselves on our record of success.
learning from experience
Our team works hard to deliver projects on time and within budget. Quality engineering and customer satisfaction are our main objectives.
- client satisfaction – 90%
- Projects on time – 85%
- Leachate treated – 95%
Leachate generation is a major problem for municipal solid waste (MSW) landfills and causes a significant threat to surface water and groundwater. Leachate can be defined as a liquid that passes through a landfill and ends up contaminated by interaction of toxic dissolved or suspended elements. Treatment of leachate remains one of landfill engineering’s most complex problems to solve.
the nitrogen cycle
Nitrogen is a major plant nutrient, but too much nitrogen in the form of nitrates, in the effluent can cause explosive plant growth and algal blooms in watercourses, lakes and ponds. As the process also create anoxic conditions, it can be deadly to aquatic lifeforms.
The removal of nitrogen from leachate and effluent is therefore a normal requirement for the treatment of sewage and other waste waters. The removal of ammonia from contaminated water is facilitated via a process known as the ‘Nitrogen Cycle’.
