AT_VF_reedbed 3D模型

3D model of the AT vertical flow reedbed. The vertical flow reedbed is the most efficient of the 3 reedbed designs. Reedbeds allow ecologic water purification at low cost. The AT vertical flow reedbed design is a slightly altered version of a traditional VF reedbed. Due to the simple design (especially the filter), it is cheaper to make and even slightly more efficient, and due to the placement of the water tank above the pipes, it also does not require a electrical pump (it is instead gravity-powered). A white plastic is placed above the tank to reduce water evaporation. The pipes are suspended above the soil to allow the plants to be placed over the entire soil surface. A EPDM plastic is placed in the soil to direct the water filtered by the plant roots towards the through on the right.
