On the way to solve problems. The usual way to the industrial estate, which is assigned to the global utility service co., Ltd. (GUSGO) as administrator. To solve the problem without the use of chemicals to prop up the colors or copper sulfate in the removal of algae. There is a charge per month 25,000 baht (Lieutenant splendour fairly classical Hiran, 2555) each year, the loss in this budget to 300,000 baht and how to use a somewhat trickier is to check the age of the algae before. If the substance is used to prop up the algae Microcystis algae types, particularly for aeruginosa which is greenish blue algae, this species can produce toxins Microcystin name which is a carcinogen. Cannot be used in water.One interesting approach and low cost is the use of constructed wetland technology in which a wastewater treatment system that relies on natural processes are becoming more and more popular nowadays. Especially in the use of the improved quality of treated water. But the need to reduce the amount of nitrogen and phosphorus before venting to waste receptacle. Which are the advantages of this system is simple and does not require the use of technology in the treatment of high? Therefore, in order to reduce the amount of nitrogen and phosphorus in raw water study has studied the effectiveness in reducing nitrogen and phosphorus compounds in reservoirs using Palm because it is a plant that can ease. Faster growth. Resistance to the environment better suited for use in constructed wetland system, floating Island, but there are limitations to land plants, although there is a report from the Department of land development that the vetiver system can be grown in the floating Island (Floating Island Wetland treatment) but no reports confirmed by other agencies or foreign research.
