Best practices for treating ammonia in landfill leachate
pH is an important wastewater parameter for landfill leachate because pH affects the concentration of ammonia and ammonium present in the wastewater. At a constant temperature (e.g., 20°C) and at a neutral/lower pH ( 7), the ionic form—ammonium (NH4)—is 100 percent present, and at a higher pH (>10) the gaseous form—ammonia (NH3

Treatment of Ammonia in Landfill Leachate - Xogen
AEO LANDFILL LEACHATE PROJECTS LEEP Landfill (Montreal, QC, Canada) Project Description: In July 2025, Xogen operated its AEO technology to remove ammonia and H2S from the raw leachate using its mobile treatment unit. This landfill is located in populated community and faces pressure from the city to address the ammonia problems in its leachate.
Leachate may also contain heavy metals and high ammonia concentration that may be inhibitory to the biological processes. On-site leachate treatment is an alternative to the increasing costs associated with hauling leachate to a local wastewater treatment plant. These treatment facilities are designed to fulfill the specific needs of individual
Treatment of old landfill leachate with high ammonium
old leachate. According to Yuan et al. [7] pre-treatment of old leachate via air stripping followed by co-treatment with wastewater in an aerobic SBR (V leachate/V wastewater =2.5%) obtained 87% and 100% of COD and phosphorus removal, respectively. Similar results have been reported in other research works [8, 9]. However, increasing volumetric
Leachate is a wastewater that can have negative public health and environmental impacts if it is allowed to infiltrate into groundwater. Landfills are presently engineered to prevent leachate from reaching the groundwater and also to collect and treat leachate through various wastewater treatment methods.

Saltworks Accelerates Commercialization of Ammonia
Ammonia Splitter reliably removes ammonia from municipal wastewater, landfill leachate, and other waste streams. Ammonia in wastewater is a growing problem due to its detrimental impact on aquatic ecosystems. Ammonia Splitter works in extreme conditions where conventional approaches are unable to operate.

- What is polyaluminium chloride (PAC)?
- It is a yellow-colored, water-soluble solid. Polyaluminium Chloride (PAC) 28 percent and Polyaluminium Chloride (PAC) 30 percent are the two forms of the chemical. This chemical has many industrial applications, but it is most commonly used in the flocculation processes used in water treatment industries.
- What is polyaluminium chloride used for?
- Polyaluminium chloride (PAC) is a chemical compound that is widely used in various industries and applications. Here are some common uses of PAC: Water Treatment: PAC is extensively used in water treatment processes, particularly in the purification of drinking water and wastewater treatment.
- What is high-purity poly-aluminum chloride (PACL)?
- Poly-aluminum chloride (PACl) is one of the common coagulants for water and wastewater treatment. A new Chinese national standard of PACl has been implemented, where the concentration of insoluble substances, iron and heavy metals is to be controlled strictly, then researches on the preparation of high-purity PACl are needed.
- How many types of polyaluminium chloride are there?
- There are four types of polyaluminium chloride for sale for water treatment, specifically PAC 30% 01&02. The other types, PAC 30% 03 and PAC 28% 04, are used for industrial wastewater treatment. The four types can be easily distinguished by color, from white to light-yellow and deep-yellow.
