Greywater Flow Characteristics for Closed Channel Maintenance

Knowing the characteristics of wastewater and its interaction with channel is crucial to finding a suitable model maintenance method solve closed problem. The purpose this study find relationship how much it influences in channels analyze limit deposit velocity (LDV) so that there no deposition. parameters used are density, oil fat, specific gravity, total suspended solids, dissolved kinematic viscosity. flow velocity, discharge, Reynolds number, friction coefficient, energy loss, hydraulic gradient. experimental research by simulating closed-channel prototype. made from an acrylic pipe length 6 m diameter 0.064 m. Simulations on each sample discharge variations were 0.005, 0.004, 0.003, 0.0015 m3/s. Velocity measurements at 0.5 water level height distances 0, 2, 4, results showed nature composition velocity. large value shows small. content considered load must be transported end channel. When increases, will increase, number loss large, while coefficient inversely proportional number. velocities clean samples 2.90 - 1.07 m/s, tofu making 2.83 household 2.74 0.85 laundry 2.84 1.03 workshop 2.54 0.66 m/s. for 1.49 m/s prevent deposition channels.
