PROCESS FOR AUTOMATICALLY ADJUSTING THE pH OF AN AQUEOUS TREATMENT SOLUTION AND SOLID CLEANING AGENTS SUITABLE THEREFOR

摘要

The pH of an aqueous treatment solution is to be automatically adjusted from the acid to the alkaline. This is achieved in that the desired acid pH is set in an aqueous bath with the simultaneous or subsequent addition of an ammonia-generating and/or organic carboxylic acid-consuming enzyme and its substrate, whereupon the enzymatic reaction is allowed to continue until the desired final pH is attained.
