การบำบัดฟอสเฟตจากน้ำเสียด้วยวัสดุกรองร่วมกับเปลือกหอย

The objective of this research was to study the treatment of Phosphate from wastewater by filter material with shells. Various parameters include pH temperature turbidity DO nitride ammonium and phosphate were investigated and compared before and after filler wastewater. The results show that the quality of wastewater after treatment enhancing with adding filter material with shells. The optimum ratio treatment of phosphate is resulting in maximum values was around 0.05 mg/liter (50% compare with wastewater before treatment) with formula no. 3 that not have time to filler. Moreover the results demonstrated the treatment of Phosphate from wastewater by filter material with shells can be improvement the value of turbidity nitride ammonia and DO for wastewater.
