Caustic Recovery from Textile Wastewater

Caustic is commonly used in the textile industry for processes such as bleaching, pH regulation, etc., inevitably leads to generation of caustic wastewater. To adhere to the regulations, caustic wastewater requires neutralization to circumneutral pH, alongside with other treatment processes before discharging.Effective treatment of caustic wastewater holds significant importance, especially when the caustic solution can be purified and reused in the process. This approach not only facilitates the reutilization of purified caustic solutions but also leads to a notable reduction in wastewater volume, which is a cost effective and environmental friendly solution.
