DEWATERING OF SEWAGE SLUDGE

The objectives of water protection policies make constantly increasing requirements on more thorough waste water purification. Therefore, a further increase in the volume of sewage sludge produced world-wide is anticipated in the future.

Both municipalities and industry are obliged to dispose of the growing quantities of sewage sludge in an environmentally safe and economical manner. The disposal of sewage sludge must be secured in the future, employing the latest standards of technology to ensure that valuable materials are recycled. The optimum and economical dewatering of sewage sludge is a central step for all recycling possibilities.

The method of disposal and the associated requirements on the degree of de-watering determine the economy of a dewatering unit. Any increase in the concentration of solids is beneficial in terms of reducing landfill and transport costs.

To allow the sewage sludge to be recycled or disposed of in line with the corresponding requirements, optimum dewatering is necessary before drying, incineration or dumping. The decanters from Huading Separator fulfil these requirements by a high g-force (separation efficiency) and optimum torque control.

A high degree of dewatering guarantees a substantially reduced sludge volume and thereby significant cost reductions for:

━ Transport
━ Landfill
━ Energy consumption during drying or incineration
