Ishikawa Stockbreeding, Inc. had faced problems with labor and maintenance works accompanied with the handling of excess sludge, generated from their piggery wastewater treatment plant. However, the installation of Volute Dewatering Press solved all these problems and this resulted in a big fall in labor and maintenance works for excess sludge treatment.
Ishikawa Stockbreeding, Inc. had faced problems with labor and maintenance works accompanied with the handling of excess sludge, generated from their piggery wastewater treatment plant.
Before installing Volute Dewatering Press, the excess sludge had been treated by all of the workers in the firm through a series of process; pumping the sludge, carrying out and disposing. These time-consuming and burdensome works had been regarded as major problems.
Ishikawa Stockbreeding, Inc. decided to install a sludge dewatering equipment as a solution to their problems. After having undergone a thorough examination of various sludge dewatering equipments in terms of their performance, cost and operational easiness, they decided to choose Volute Dewatering Press. Volute Dewatering Press with its clog-free-self-cleaning structure allows fully-automatic operation and these characteristics considerably minimized their burdensome works. As a result, they now have enough time for their main work, which is taking care of pigs rather than sludge handling.
In addition, they now make compost out of the sludge cake discharged from Volute Dewatering Press by using a composting unit. The compost made is sold as a product and they now pay 'zero cost' for sludge disposal
We are proud to be given such a comment by the president of Ishikawa Stockbreeding, Inc., 'Unfortunately, some people in the same profession think that a fine for sludge disposal is cheaper than the cost to buy equipment, which means that they do not understand the fundamental meaning of wastewater treatment. However the Volute Dewatering Press has made our work easy.'
