  • Boiler blowdown - Lenntech

    Boiler blowdown wastewater treatment. Boiler blowdown wastewater properties depend on pretreatment for makeup water and on number of cycles of concentration. In any case, the temperature, the pH and level of dissolved solids at least of the blowdown water must be adjusted before going to sewers.

  • Purpose of Carrying out Blowdown in a Boiler

    Blowdown is necessary to control the level of concentration of the solids, and this is achieved by the process of 'blowing down,' where a certain volume of water is blown off and is automatically replaced by feed water thus maintaining the optimum level of total dissolved solids (TDS) in the boiler water.
