Three Sludge Dewatering Lines for Baiyun, China

On October 25, 2010 three sludge dewatering lines left our Düren plant en route to our customer Zhumadianshi Baiyun Paper, a pulp and paper mill situated in the north of China.

This consignment is the largest order in the history of BELLMER KUFFERATH as a supplier of screw presses for sludge dewatering purposes. Each of the three lines basically consists of an FR flocculation reactor, an AKSE® S 175/09 disc-thickener and an AKUPRESS® BX 1000 screw press.

Altogether, the three lines are determined to handle a mixture of mechanical, biological and chemical sludge. The characteristic feature is the very high percentage of chemical sludge from precipitation, which is why waste straw was added to the sludge as structural material to support the dewatering efficiency. The necessary equipment mainly consisting of bunkers including moving floors, conveyor belts, dosing and mixing systems has also been part of our scope of supply.

Our services also encompass the supply of the entire electrical equipment together with all relevant instrumentation and control system.

An important role in the success of this order has to be attributed to our colleagues of Bellmer Shanghai. On the one hand for their commitment and assistance during the project and the order handling process. On the other hand, it was the first time that a shipment was supplemented by a number of essential components made in China.

The lines are scheduled to be assembled on site in January and February and planned to go into operation in spring 2011.
