CONFIGURING AND TUNING PERISTALTIC PUMPS
The following is a set of guidelines to be used when
confi guring the peristaltic pumps that inject Coag and
EC chemicals into the WaterMaze water treatment
system. Materials required for this process are included
in the WaterMaze CoAg Test Kit. Materials include:
• Small quantity (4oz ea) of CoAg+ and EC+ chemi-
cals to be used in system
• 500 ml capacity test sample containers
• Clean standard sized plastic transfer pipettes
(20 drops/ml, 3.2 ml draw)
• Filter Paper (50, 20 and 5 micron)
Determining Required
Chemical Concentrations:
1. Obtain a representative water sample of the
waste stream (1-2 gallons).
NOTE: Sampling is highly important. The sample
should be representative of what will be processed
by the CoAg treatment system. In other words,
proper pretreatment should be applied to remove
heavy solids (e.g., those that settle quickly within
say 10 to 15 minutes) and to remove free oils (e.g.,
oils that can be skimmed from the surface of the
water).
2. Pour a 500 ml sample into a clear container
(beaker, cup, etc.)
3. Test the pH of the sample.
4. Adjust pH to 6.5 to 8. In many cases, pH adjust-
ment should be considered as part of the pretreat-
ment process. Adjusting the pH may allow for
additional separation of oils and solids.
5. Add 2 drops (.1 ml) of CoAg+ coagulant to the
sample.
6. Mix vigorously for at least 45 seconds.
7. Observe the reaction noting the start of coagula-
tion (clumping together of solids).
8. Add 3 drops (.15 ml) of EC+ polymer and gently
mix (slowly) for 30 seconds.
9. If successful, a separation of the solids should
occur with the majority of the solids falling to the
bottom of the sample container with clear phase
of liquid on the top of the sample.
10. This sample can then be fi ltered through 50
micron paper to remove the fl occulated solids.
11. If a separation does not occur, repeat the above
steps with a new sample and add one additional
drop (.05 ml) of CoAg+. Unsuccessful results
after further adjustments may indicate that a dif-
ferent treatment technology is required other than
Chemical treatment.
