The production of dyes and dyeing of fabrics utilizes a lot of water in the whole process. Printing, which is a part of dyeing, leads to discharging toxic waste. Therefore, textile pre-treatment, printing, dyeing, and finishing processes are responsible for utilising and discharging all types of chemical waste. These processes produce effluents that contain high concentrations of salts, and high biological oxygen demand (BOD) or chemical oxygen demand (COD) values. Hence, Textile industries must use water treatment plants within their process.
Multiple Effect Evaporators (MEE) or Mechanical Vapour Recompression (MVR) are commonly used to treat this wastewater, in which the liquid is concentrated. One major disadvantage of MEE and MVR is fouling while concentrating liquid, which can lead to decrease evaporation capacity and increase operational cost.
With the Klaren’s self-cleaning heat exchanger technology, you can achieve up to zero fouling operations in your MEE and MVR systems, keep system clean and run plant without any operational constraints.
