3.1 system of artificial Wetland, swamp, Water Surface Free form (FWS) is commonly used to improve the quality of the treated waste water from the pond after stabilization (Stabilization Pond) and the characteristics of the system, this is a pond where there is soil compaction or paving with HDPE sheet level so that the waste water flowing horizontally, parallel to the ground. Pond would have a different depth to achieve a completely natural healing process, the structure of the system is divided into three sections (possibly the same pond, or several, depending on the design) is the first part, the part that has grown with the roots emerge from the water and high style Island soil, planted, such as click.Click the vetiver Typha to aid in filtration and sedimentation of suspended matter and organic sedimentation. Making the removal of suspended matter and organic matter have partially reduce suspensions and good value b o, the second part is the part that has a floating plant on the surface of the water, such as the Lotus position screen, including smaller plants that hang suspended in the water, such as algae, duckweed screen etc. These two areas will not have to grow plants that look like high-water emerge from in the first part and third part. The water in this section are exposed to air and sunlight makes with the growth of algae, which increases dissolved oxygen (DO), the type of microorganisms, oxygen, biodegradable water soluble organic reducing value b o well in polluted water and the conditions, nitrate (Nitrification) Philadelphia pre-equipped with part three. Plants are grown in the same way, the first part to help filter out the remaining solids and cause weather di Nitro Trinidad Philadelphia (Denitrification).
