Draw and complete a flowchart and perform a degree of freedom analysis. A wastewater (Feed) containing 5 weight% organic matter (C), 8% sand (S) and the balance water W) is fed to a separation unit (Unit 1) at a mass flowrate of 1000 kg/hr. The first stream (stream 11) leaves the separation unit with 80% sand and the balance water. Furthermore, 90% of the sand n the Feed is recovered in stream n1. A second stream from the separation unit (n2) is sent to a membrane filtration unit (Unit 2) to remove the remaining sand and organic matter.

Identify the unknowns and write all independent equations for this system. Note 1: Do not solve for the unknown compositions or flowrates. Note 2: Do not perform the degree of freedom (DOF) for the second unit or the overall process.

Question
Transcribed Image Text:Draw and complete a flowchart and perform a degree of freedom analysis.
A wastewater (Feed) containing 5 weight% organic matter (C), 8% sand (S) and the balance water
(W) is fed to a separation unit (Unit 1) at a mass flowrate of 1000 kg/hr. The first stream (stream
ni) leaves the separation unit with 80% sand and the balance water. Furthermore, 90% of the sand
in the Feed is recovered in stream ni. A second stream from the separation unit (n2) is sent to a
membrane filtration unit (Unit 2) to remove the remaining sand and organic matter. Two streams
leave the membrane filtration unit (stream n3 and n4). The overhead stream from the membrane
filtration unit (stream n3) contains 99% water and the balance organic matter.
a) Draw and complete a flowchart for this process
b) Select your system only around Unit 1 and perform the degree of freedom (DOF) analysis.
Identify the unknowns and write all independent equations for this system.
Note 1: Do not solve for the unknown compositions or flowrates.
Note 2: Do not perform the degree of freedom (DOF) for the second unit or the overall process.
