CASE HISTOR

Evaluations of ChemTreat Solutions

Automated Feed Systems at

Southeast Paper Mill

A large Southeast Paper Mil l was

experiencing poor control with their

water treatment supplier who was

using pace and chemical verification

instrumentation. The mill was ex-

periencing major variances in cycle

control, conductivity, P-alkalinity,

and phosphate control. ChemTreat

had investigated the causes of these

variances and submitted their rec-

ommendations for improvement. As

a result, ChemTreat was given the

opportunity to turn things around.

BACKGROUND

Major variances in cycle control, condu

ity, P-alkalinity, phosphate control, and ove

chemical control.

PROBLEM

After assessing customer needs and pr

ous program performance using ChemTra

software, ChemTreat installed an advan

version of their ChemTreat Solutions C

trol and Monitoring System which inclu

proportional chemical feed pumps, blowd

control based on cycles, and correct checal feed injection points. As a result, the c

tomer is able to precisely control and mon

the chemical and blowdown of their syste

at a very tight control range which had ne

before been seen at this facility. The neat f

of products by the ChemTreat Solutio

Control System eliminated the costly, m

tenance-intensive, and inaccurate feed

control system previously used by the incbent supplier.

The ChemTreat Solutions System

datalogs other critical system parame

such as hardness, silica, sodium, and turb

to ne tune system performance. Evalua

and results after installing ChemTreat S

tionsare shown in the gures to follow.

SUMMARY

Evaluation of the ChemTreat Solutions System was considered a major success. P

management agreed use of the on-line system was a signicant process improveme

As a result, the mill will realize improved treatment results and energy savings of at le

$96,000 per year.

Once ChemTreat wasawarded the contract, they hitthe ground running. We had an

outage window where signicant

work had to be completed for

the changeover. The work was

completed ahead of schedule

with very few issues. The boiler

came on-line and everything

worked. Since the shutdown, the

tuning, optimization, and auto-

matic operation has exceeded

our expectations. We are already

seeing signicant return on our

investment. We have just seen

the tip of the iceberg. ChemTreat

has identied many other oppor-

tunities which should pay off with

signicant savings and improve-

ments to our operation.
