Now more than ever, MILNOR CBW's are used in installations with severe changes in soil classification. Many years ago, MILNOR proposed the Compatibility feature in the MILNOR CBW and have used this in selected cases for many years.

A large number of "bath exchange" CBW's have been produced in the recent past. These machines allow a complete drain and refill of all or certain modules to accommodate changes from one goods class to another. The result is non-chemically dosed modules of fresh water that must be brought to proper residual chemical values in the period of one transfer. In some installations, an empty module is dosed to accomplish this residual value. In practice, this may work, but when the customer runs the CBW completely empty, he continues to pump chemical into the machine.

The rules of thumb for the inject are as follows with customization invited after titration.

RULES:
1. Establish the maintenance dosage for each goods classification.
2. When goods follow an empty (module with no goods) or a purge (a complete drain and refill) use the maintenance dose x 3 for this bath.
3. For all combinations of goods following other goods use the ratio of the maintenance doses to determine this dose. As an example, Normal Maintenance Dose (Squared) divided by Last Dose in This Module.

See the attached "Table 1" which is representative of a "compatibility page" within the CBW MILTRON control. Please note that titration must be performed when goods follow an empty module so that the calculation above can be tested. Be careful not to make maintenance dosage decisions within the first two modules after a goods classification change.

You should launch the attachments and then save them on your PC locally. We recommend that you save a spreadsheet for each customer and each chemical.
