Midterm

Report

...

For

...

those

...

of

...

us

...

new

...

to

...

the

...

Demo

...

Plant

...

team,

...

a

...

lot

...

of

...

the

...

semester

...

so

...

far

...

has

...

been

...

spent

...

familiarizing

...

ourselves

...

with

...

general

...

principles

...

and

...

operation

...

of

...

the

...

actual

...

plant,

...

as

...

well

...

as

...

with

...

using

...

MathCAD

...

and

...

the

...

basic

...

MathCAD

...

files

...

and

...

programs

...

used

...

for

...

plant

...

design.

...

This

...

was

...

necessary

...

in

...

order

...

to

...

be

...

able

...

to

...

partake

...

in

...

the

...

design

...

of

...

a

...

new

...

demo

...

plant.

...

Along

...

with

...

Christina

...

,

...

I

...

determined

...

a

...

factor

...

to

...

more

...

accurately

...

represent

...

flocculation

...

efficiency

...

in

...

the

...

MathCAD

...

flocculation

...

model

...

used

...

for

...

plant

...

design.

...

We

...

did

...

this

...

by

...

observing

...

the

...

flocs

...

in

...

the

...

current

...

plant,

...

and

...

then

...

testing

...

various

...

efficiency

...

values

...

in

...

the

...

MathCAD

...

design

...

program

...

created

...

by

...

James

...

Leung

...

.

...

It

...

was

...

assumed

...

that

...

he

...

correct

...

efficiency

...

factor

...

was

...

the

...

one

...

that

...

returned

...

a

...

plant

...

design

...

with

...

a

...

length

...

similar

...

to

...

the

...

length

...

at

...

which

...

we

...

were

...

seeing

...

the

...

largest

...

flocs

...

in

...

the

...

actual

...

flocculator.

...

Once

...

we

...

felt

...

confident

...

with

...

all

...

of

...

these

...

things,

...

we

...

were

...

able

...

to

...

use

...

the

...

Demo

...

Plant

...

MathCAD

...

Design

...

program

...

created

...

by

...

James

...

Leung

...

to

...

create

...

a

...

new

...

design

...

for

...

the

...

flocculator,

...

based

...

on

...

the

...

current

...

plant,

...

but

...

with

...

a

...

different

...

length

...

intended

...

to

...

maximize

...

efficiency.

...

We

...

have

...

also

...

been

...

discussing

...

in

...

depth

...

future

...

construction

...

goals,

...

and

...

beginning

...

plans

...

for

...

a

...

new

...

Flow

...

Control

...

Module

...

for

...

the

...

desired

...

plant

...

flow

...

rate,

...

based

...

on

...

head

...

loss

...

equations

...

and

...

using

...

the

...

FCM

...

design

...

tool

...

,

...

a

...

new

...

sedimentation

...

tank

...

(possibly

...

with

...

the

...

inclusion

...

of

...

a

...

sludge

...

blanket),

...

and

...

a

...

new

...

flocculation

...

tank

...

design.

...

On

...

the

...

wiki,

...

I

...

have

...

created

...

the

...

Demo

...

Plant

...

Flocculation

...

added

from

the

of

the

plant

...

to

the

photos

...

...

in

the

contributed

creating

all

...

As

...

plans

...

for

...

construction

...

of

...

the

...

rest

...

of

the

components

...

are

finalized,

...

we

will

be

posting

and

explanations.
