Industrial chiller unit of waste acid recovery

Steel pipe manufacturers inevitably produce wastewater and waste acid requiring treatment, and traditional evaporation and concentration methods or entrusting a qualified a third-party for recycling are expensive. The waste acid recovery unit is a low-temperature chiller for the waste acid recovery production process. The unit utilizes a new technology: frozen crystallization method. The freezing crystallization treatment of sulfuric acid pickling waste liquid is to separate the crystals of ferrous sulfate by controlling the crystallization conditions of ferrous sulfate from the waste liquid.
