What is Land Treatment System (LTS)

Chapter 9
Handbook of Research on Uncovering New Methods for Ecosystem Management through Bioremediation
Land treatment refers to the application of partially treated wastewater to the land that is designed, constructed and operated to treat wastewater through the use of crops, irrigation methods, ground and surface water monitoring to confirm to specific water quality limits. It involves the controlled application of wastewater to the land at rates compatible with the natural physical, chemical and biological processes that occur on and in the soil.

Abstract
Vegetation filter is an emerging wastewater treatment option in which phytoremediation strategies are employed for municipal applications. Short rotation woody crops combine both treatment and reuse of effluent and operate on ‘zero discharge' concept. This multifunctional system has become a viable alternative solution for wastewater treatment as well as biomass production by utilizing nutrient rich wastewater as cost efficient fertilizer. Fast growing species like Salix, Eucalyptus, and Populus with high water and nutrient requirements, highly selective heavy metal uptake and high evapotranspiration rate are generally preferred as vegetation filters for wastewater treatment. However, site-specific factors such as wastewater composition, climate, soil type, permeability, species or clonal characteristics must be taken into account when considering irrigation with municipal wastewater. This chapter discussses the prospects for vegetation filters to remediate contaminated water and soil and also facilitate recycling of valuable resources in society.
