Halophyte Zeolite Wetlands (HZW)

This technology generates new water resources for irrigation from the treatment of agro-industrial wastewaters through the usage of a holistic nature-sourced technology which combines a nanocomposite clarification-sedimentation system for the TSS removal, aerated bio-reactors for the COD and nutrient removal, and halophyte-zeolite wetlands for the sodium removal.
Technology validated in lab.
Basic technological components are integrated to establish that they will work together. This is relatively “low fidelity” compared with the eventual system. Examples include integration of “ad hoc” hardware in the laboratory.
Selected for Testing
Selected for Testing: This innovation has been selected by BRIGAID because of its promising value for reducing the risks or the impacts of extreme hydro-climatological events. After a rigorous assessment, BRIGAID has positively approved the innovator’s testing plan, and decided to provide ongoing support for the testing activities.
The pre-treatment modules (nanocomposite, and aerated bioreactors) already work and have been demonstrated under operational conditions in a winery industry (TRL 7). The SAR reduction module through the use halophyte-zeolite wetlands is at TRL 4 and it needs to be demostrated in combination with the pre-treatment modules.

How does it work?

Dairy wastewaters will be pumped into a nano-composite system (patent) that reduces the TSS to level that would prevent clogging of the aerated cells. The later is based on previously funded EU project (MISSTOW) that reduce the COD by more than 95%. The last module is a green module of smart substrates and halophytes that will reduce the SAR using exchange reactions and plant up take.
