Landfill Leachate Treatment Applications

Landfill Leachate Treatment

Effluents from waste (leachate) are highly polluted and must be treated efficiently before they can be discharged into a municipal sewage plant or a local watercourse. Conventional treatment technologies do not suffice. Chemical processes are not economic due to the high pH buffer capacity of the leachate. Hardness and chlorides in the leachate are a problem for many plant components. Besides, process knowhow and operating experience are indispensable for an effective elimination of the harmful ammonia nitrogen. Certain processes also produce residues such as concentrates, which must be removed from the landfill body. This disposal is very expensive. WEHRLE is a reliable and experienced plant constructor for those applications. The first leachate treatment plants were built in 1991 and have been in constant operation ever since. This is not only proof of excellent technology but also for sustainable efficiency with stable, predictable, low operation costs.

landfill leachate treatment

1.Leachate Main Features：（1）High concentration of organic matter. （2）High salt content；（3）High ammonia and nitrogen content. （4）C/N/P Microorganism nutrition ratio disorders. The water quality, volume and temperature will also change, and the heavy metal content is complicated. 2.Special reverse osmosis membrane technology Features : 1)Super NF/RO High Anti-fouling Membrane is not easy clogged, and the system is with good stability. Not affected by the effect of biochemical treatment . Longer service life 2) Super NF/RO High Recovery Rate The operating pressure of Super NF/RO is higher, and with higher recovery rate up to 90-95%. It will yield less concentrated water and reduce the concentrated water treating cost. 3) Concentrated water evaporation treatment Thoroughly solve the problem of pollutant enrichment caused by concentrated water reuse, so that the biochemical system and membrane system can maintain long-term and efficient operation

Landfill leachate wastewater treatment

Landfill leachate is the runoff water that occurs from operational or closed landfills. This water flows at lower rates on dry days when naturally occurring moisture percolates out and at higher rates on rainy days when the leachate waters are combined with stormwater.

Evaporation technology for waste industry

The leachate produced by the waste in the landfill is an extremely pollutant effluent that requires high effective treatment processes to comply with the very strict limits for discharging operations. EVALED evaporators are a technological solution which allow to exploit the biogas cogeneration for the full or partial power supply of the plant within the limits of the environmental regulations and to reduce the relevant costs for thermal energy and leachate disposal.
