Application of stratified filter and wetland to stabilize the temperature and pH of blackwater

A Constructed wetland is a suitable wastewater treatment method for developing countries since it is inexpensive and easy to implement. Blackwater treatment can be maximized with the combination of stratified filtration method and wetland system using Vetiver grass and Cattail plants. This research aimed to examine the effectivity of the combination method to improve the quality of wastewater based on the parameter of temperature and pH. Blackwater flows into the stratified filter consisting of gravel, charcoal, and sand material, then flows into wetland tube with the residence time of 2-day, 4-day, and 6-day. The result of water quality measurement will be compared with the quality standard based on the government regulation.
