The continued increase in the cost of chemicals energy and water makes their recovery more important today than it was 20 years ago when ultrafiltration and hyperfiltration were first introduced to the textile industry. While the filtration techniques have only been used at a few installations, these plants have been able to save enough to pay for the recovery process in one to two years. One key to having a successful recovery operation is to have good automatic control of the process. This can drastically improve the economics of the textile process as well as minimizing the cost of the recovery system. The recovery of PVA, indigo, caustic and preparation chemicals will be presented.
