8. Literature Survey Some Scientific Studies Heavy metal
rejection was evaluated using a sugarelectrolyte draw solution. The
impact of various cleaning agents on membrane performance was
tested[2]. The feasibility of using the Vertically Aligned Carbon
Nanotube membrane for water purification was examined[3]. A
cost-effective method which is for phosphorus removal from reject
water of sludge dewatering process by using supernatant from sludge
lime stabilization (SLS) processes was studied[4]. 05.05.2015

15. Pipe Flow Analysis When the water flows through the pipes
two types of losses will occur: 1. Major Losses (Frictional Losses)
2. Minor Losses 05.05.2015 15Yeditepe University, Istanbul
16. Pipe Flow Analysis 1. Major Losses (Frictional Losses) Pipe
diameters are selected with respect to flow rate and velocity for
each floor. Velocity limit (1.5 m/s) is checked for diameter
selection. Reynolds number is calculated and flow regime is
checked. Friction factor (f) is calculated by using (f=64/Re) for
laminar, and checked from moody chart for turbulent flows. Length
of the pipes are chosen as 4 m. Head loss is calculated by using :

20. Pipe Flow Analysis 2. Minor Losses Piping systems include
fittings, valves, inlets, exits etc. Additional losses occur
because of flow separation and mixing due to fittings. The minor
losses associated with Velocity (V) Loss Coefficient (KL) Gravity
