Remedial Applications: Leachate Treatment

Overview

Rain fall onto landfills is the main contributor to the generation of leachate, and is by far the largest contributor for modern sanitary landfills which do not accept liquid waste. Additional leachate volume is produced during waste decomposition, and surface water will sometimes run onto waste from its surroundings.

The environmental risks of leachate generation arise from it escaping into the environment around landfills, particularly to waterways and groundwater. It has high organic contaminant concentrations and much higher levels of ammonia than found in any other organic effluent, along with other pathogenic microorganisms and toxic substances.


Cleanup Process

Leachate is characterized by high values of COD, pH, ammonia nitrogen and heavy metals. These factors make leachate treatment difficult and complicated. There are many different methods used to treat the landfill leachate. Most of them are adapted for wastewater treatment processing and can be divided into two main categories:

1. Biological Treatments
  • Aerated lagoons
  • Activated sludge
  • Anaerobic lagoons and reactors

2. Physical/Chemical Treatments
  • Air stripping
  • pH adjustment
  • Chemical precipitation
  • Oxidation and reduction
  • Coagulation
  • Carbon adsorption and ion exchange
