Abstract
A wetland system for treatment of wastewater comprises first and second vertical constructed wetlands connected in series, the first and second vertical constructed wetlands each including a bottom drainage layer, a main filter layer above the drainage layer, and a distribution layer above the main filter layer comprising a plant, wherein the bottom drainage layer of both the first and second vertical constructed wetlands comprises gravel, the distribution layer of both the first and second vertical constructed wetlands comprises agricultural sand, and the main filter layer of the first and second vertical constructed wetlands comprises a bio-plastic media.
Claims14
A wetland system for treatment of reverse osmosis (RO) reject wastewater, the system comprising:
- first and second vertical constructed wetlands directly connected in series, the first and second vertical constructed wetlands each including a bottom drainage layer, a main filter layer above the drainage layer, and a distribution layer above the main filter layer, the distribution layer comprising a salinity tolerant plant;
- and
- a granular activated carbon biofilter connected directly to the second vertical constructed wetland;
- wherein
- the bottom drainage layer of both the first and second vertical constructed wetlands comprises gravel having a first size and a second size different from the first size,
- the distribution layer of both the first and second vertical constructed wetlands comprises agricultural sand,
- the main filter layer of the first and second vertical constructed wetlands comprises a bio-plastic media.
