Du-Lite Waste Water Treatment Chemicals and Equipment

All rinse water used in the Du-Lite black oxide process must be treated before discharge to your septic system or local sanitary sewer system. Before disposing of rinse water, you should contact environmental authorities in your area to be certain that no law will be violated by using these disposal procedures. Fortunately, there is an easy way to test rinse water to determine whether it is acidic, alkaline or neutral.

The method used is to measure the pH level. What is meant by pH? pH uses a scale of 1 to 14, 7 represents the pH of distilled water which is neutral. A pH of 6.5 is slightly acidic. The lower the numbers the stronger the acid content of your waste water sample. A water sample with a pH of 8 is slightly alkaline the higher the numbers go to 14 the stronger the alkalinity becomes. Rinse water from a black oxide line has a pH of 14 and must be lowered with Du-Lite's Waste Water pH Adjustment Compound to a pH of 7. At this pH, all alkalinity has been neutralized and all nitrates and nitrites in the rinse water have been destroyed.

The pH level of the waste- water can easily be determined by using multi-colored pH test strip papers. Dip the colored area of a pH test strip into the waste- water for a few seconds, then remove it and observe the color change in the colored area of the test strip. Match this color on the container and read off the pH value. These strips are a fast, simple and accurate way to test the acid/alkaline nature of any waste rinse water.

Du-Lite can customize waste water treatment equipment to satisfy your specific requirements. Please contact one of our specialists at 860-347-2505 for more information and a quote.

Du-Lite Waste Water pH Treatment Compound

Waste water treatment compound is a white powder used for neutralizing black oxide alkaline solutions.

For best results when treating waste water, mix Du-lite’s Waste Water Treatment Compound, 16 oz. per gallon, with cold water. (Example: 10 gallons of water mixed with 10 lbs. of Waste Water Treatment Compound).

It is much easier to add the liquid Waste Water Treatment Compound to the waste water to be treated then it is to add as a powder.

NEVER DISCHARGE TO A SEPTIC SYSTEM RINSE WATER OR SPENT SOLUTION FROM A BLACK OXIDE LINE THAT HAS NOT BEEN PH ADJUSTED. IT WILL KILL THE BACTERIAL ACTION IN THE SYSTEM AND SHUT IT DOWN..

 PH Balancing

(Float switch in pH adjusting tank should be set to detect liquid 6-8 inches from the top of
the tank, along with the capacity in gallons of sump tank being used.)

1. Tank monitor will give audio and visual indication that liquid is at pH adjusting level
2. Operator will shut off incoming water supply to rinse tank(s) by closing rinse water supply valve
3. Check pH, Add waste water pH treatment compound and mix solution (a paddle may be used)
4. Check pH, Once neutral pH is achieved, Operator will drain tank by opening drain valve
5. After tank is drained, close drain valve and open rinse water supply valve

The Easy Opener

Due to new shipping regulations by the DOT, we are now required to ship our hazardous and corrosive materials in five-gallon pails with drive on covers. Some of our customers are having trouble removing these covers and have elected to purchase from us "The Easy Opener"; it removes the lid with ease. If you do not already have this device we suggest you include this with your order.
