There is a requirement for Landfill Leachate Treatment for ammonia and other pollutants removal. Can anyone help me by providing a project of Ammonia Stripping or similar technology for Landfill Leachate Treatment?

Landfill leachate characteristics and composition differ significantly from site to site and along the time, according to several factors, such as the landfill type, the climate and geographical situation, and the landfill age. It contains a complex mixture of organic substances (biodegradable and refractory), ammonia-nitrogen, heavy metals and chlorinated organic and inorganic salts.
Wastewaters with ammonia concentration greater than 100 mg/L usually require steam stripping; air stripping is ideally for ammonia concentrations between 10 mg/L and 100 mg/L. Selective ion exchange: Contact with specific ion exchange media can remove ammonia, nitrite and nitrate from leachate through adsorption.
The type of treatment process used will depend on several factors:
1. The specific nitrogen compounds (e.g., ammonia, ammonium, nitrite, nitrate and organic nitrogen) that require removal or reduction
2. The initial concentrations of the nitrogen compounds in the raw leachate
3. The target post-treatment concentration requirements (i.e., discharge permit standards)
4. Multiple other criteria, including leachate chemistry factors mentioned previously.
A physicochemical process called ammonia stripping may be used to remove ammonia from sewage. Chemicals are added to convert ammonium ions into ammonia gas. The sewage is then cascaded down through a tower, allowing the gas to come out of solution and escape into the air. Various leachate treatment technologies like coagulation- flocculation, adsorption by activated carbon, biological treatment and reverse osmosis are reviewed and there treatment efficiency depending on operating conditions at the sites
I have send you a Article on Ammonia removal from Leachate on your mailid
Dear Lokesh Kumar ,
Nice to be in touch again. Yes we provide ammonia stripping technology tailored to a broad range of wastewaters incl. landfill leachate on which we have expertise in Asia. Alternatively we our advanced AS+™ biotechnology ( https://www.modelengineering.eu/circulate_water ) converts high levels of ammonia via the nitrite shortcut and anammox directly to inert nitrogen gas at up to 99% efficiency. If interested, I would be happy to send you more info via email. You can contact me directly at https://www.modelengineering.eu/contact
