Improve rinsing while reducing water consumption as much as 90%!

Take 10 minutes and learn how to improve rinsing while reducing water consumption as much as 90%…

Long ago, the answer to good rinsing was to simply “open the valve all the way”. However, with conservation and pollution control, we are learning to turn off the water, and recover whenever possible. But what's even better, good rinsing techniques help produce quality parts.

When two rinse tanks are connected, such that water flows from rinse number two, to rinse number one (figure 1) some beneficial math results. The dragout from rinse number one to rinse number two is re-diluted so that the total dilution is almost the multiplication of the dilution in each rinse tank.

You will use less water and get better rinsing if the dragout tank is used as the rinse and is included in the chain of counterflowing rinses.

TABLE 1 – WATER REQUIRED TO DILUTE ONE GALLON OF DRAGOUT
Dilution Ratio	One Rinse	Counterflowing Rinses
	(gal)	2	3	4	5
100:1	99	10.0	4.3	3.0	2.3
1,000:1	999	31.0	10.0	5.4	3.8
5,000:1	4,999	70.0	17.0	8.2	5.3
10,000:1	9,999	100.0	21.0	10.0	6.1
20,000:1	19,999	141.0	27.0	12.0	7.0

The Bottom Line: Any method used for dragout recovery or waste water minimization is made more practical and economical when water flow is reduced. It is always easier and cheaper to get one pound of materials from one gallon of water than to get one pound from 100 gallons. If you use counterflow rinsing (with or without sprays), you will get better rinsing, save an abundance of water and increase profits.
