The waste water treatment system to release the flow of wastewater flow by approximately 2-8% slopes are cultivated in the wastewater flow, causing conditions is a biochemical reaction, sedimentation, filtration and adsorption. The nitrogen and phosphorus in wastewater is being cultivated fields to use as mulch. This system can be disposed of BOD, SS 95-99%, 70-90% and dispose disposed of nitrogen, phosphorus, 50-60% (Polprasert, 1996), this system can sprinkle water volume from 3.0 to 20 meters / year to about 40 area. -280 farm typically at a rate of 6.0 to 40.0 cm water the wastewater / week) for the waste water through a sieve trap waste only. And wastewater treatment were then treated with water (Lagoon) or Aaivated Sludge respectively.
