The second condensates of the Debert Evaporator, which converts light process water for cooking corn with low solids in heavy water and to be added to the feed, is one of the by-products of the milling process, which enriches the feed as vegetable protein. These milling waters overflowed into the industrial wastewater system, increasing BOD, COD, total suspended solids and dissolved solids, temperature and pH of the water to be treated, generating an increase in the volume of chemical products required for treatment. In order to use this overflow, a previous treatment process with activated carbon was developed so that it could be used in the Tayco 1000 cooling tower as makeup water.
