The idea of Vita originates from vitamin tablets. With only a small dose, it can trigger a virtuous cycle of nature , and improves the water quality and creates a healthy ecology. The System is built with modular design; the independent units, vita, are fixed on the rustproof steel plate. When sewage flows into Vita, it will filter out the good bacteria and purify the water. The shape of steel plate can be arranged according to the field. The characteristics of its variable installation ways allows Vita to be placed in different areas such as slopes and rivers. The construction process is simple (convenient to install and disassemble) . Besides, you only needs to dissemble the steel plate during maintenance. Vita ecological water purification system includes the tertiary treatment. There is a trash rack installed on top and a grit chamber at the bottom to protect the microorganism-immobilized cell beads.
