leachate removal 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.

  • Remote level monitoring

    Leachate level control is a primary function in landfills. Although different types of pumps are used, all pumps need to be installed with a totalizing counter mounted at the top of the well head to monitor the pump cycles and to calculate the total volume of leachate removed from the well. Instead of manually monitoring the leachate level and collecting the pump count data, use FlexPower™ Counter Nodes to wirelessly send data from the pumps back to a central control location to save time and eliminate errors.
