Landfill leachate, in **collectors, landfills and incinerators**, is the outcome of percolation and leaching phenomena from stockpiled waste. The leachate produced by the waste in the landfill is an **extremely pollutant effluent**: it contains a significant percentage of **ammonia, COD, heavy metals and salinity** (chlorides and sulfates). It is therefore hard to treat and requires high effective treatment processes to comply with the very strict limits for discharging operations. Our **wastewater evaporation technologies for the landfill leachate water treatment** are an effective solution in treating highly polluted, concentrated landfill waste, very difficult to treat by traditional processes.

## Landfill leachate treatment through evaporation technologies

**Leachate water treatment** through evaporation technologies and membranes is based on the separation of water from a water-based solution. The outcomes of the leachate treatment plant are:

- **condensate or permeate**: the main stream representing the majority of the original flowrate containing water.
- **concentrate**: the smaller flow containing the majority of the pollutants; it can be sent to further super-concentration steps, to disposal or to incineration/inertization.

The solutions applied in the **landfill leachate treatments** can be used also for waste coming out from:

- wastewater collector
- digestate
- gas scrubbers
- composting

## EVALED leachate treatment system: a technological solution for leachate disposal

Amongst leachate treatment options, EVALED evaporators are a technological solution which allows to **exploit the biogas cogeneration** for the full or partial power supply of the plant within the limits of the environmental regulations.

EVALED leachate wastewater treatment processes are the solution for:

- Leachate and industrial wastewater **volumes reduction**
- **Reducing the relevant costs** for thermal energy and leachate disposal
- **Adaptability** to the incoming effluent changes
- Biogas cogeneration exploitation
- **Compliance with discharge regulations**

The evaporation technologies for this solution are the forced circulation [EVALED RV](https://www.evaled.com/rv-f-series/) evaporators and vacuum [EVALED AC](https://www.evaled.com/ac-f-series/) evaporators powered by hot/cold water coming from cogeneration.
