Rainfall and Temporal Influences on the Hydrodynamics of a Vertical Subsurface Flow Constructed Wetland Treating Domestic Sewage. [PDF]

Water Environ Res
The constructed wetland hydrodynamic study indicated the formation of preferential flow paths between Years 3 and 5. Rainfall reduced the retention time and increased dispersive flow in the sewage treatment unit. ABSTRACT This study aimed to evaluate the hydrodynamic behavior of a vertical subsurface flow constructed wetland (VSSF‐CW) treating domestic

Washing and Chopping Pre-treatment Effect of Vetiver Roots on Vetiver Oil Yield and Distillation Time [PDF]

IOP Conference Series: Earth and Environmental Science, 2021
Abstract Vetiver is a type of grass mainly used for its roots to be extracted into vetiver oil. Despite the increasing market demand, the productivity of vetiver oil in Indonesia still consider low. One of the determinant factors of the extraction yield is the pre-treatment before distillation.
