We would like to introduce a case study of a dewatering machine for surplus sludge from biological treatment that was implemented at a certain food factory. The company was considering replacing their existing dewatering machine due to its aging, and they were facing issues such as "high running costs due to the use of two types of polymer coagulants (cationic and anionic)." After conducting interviews with the customer and performing dewatering tests, we proposed the 'CS type (single cloth filter)'. After implementation, the amount of coagulant used was significantly reduced, and the decrease in moisture content also led to a reduction in disposal costs for the dewatered cake. 【Case Overview】 ■ Issues - High running costs due to the use of two types of polymer coagulants (cationic and anionic) - High moisture content in dewatered cake, leading to high disposal costs ■ Proposed Model: CS type (single cloth filter) *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study of a dewatering machine for surplus sludge from biological treatment that was implemented for a certain pharmaceutical company. The company was incurring significant costs for regular media replacement. In response, we received sludge and dewatered cake from the existing dewatering machine and conducted laboratory tests at our facility. We proposed the 'NSC type (screw press type)' and it was adopted. After implementation, maintenance costs were significantly reduced, and by reviewing the formulation of the coagulant, the coagulation state became stable. [Case Overview] ■ Issues: Significant costs incurred for regular media replacement ■ Adopted model: NSC type (screw press type) *For more details, please refer to the PDF document or feel free to contact us.

A certain food factory was considering replacing its aging dewatering machine. There were issues such as high running costs due to the use of two types of polymer coagulants (cationic and anionic), a high moisture content in the dewatered cake leading to increased disposal costs, and a preference for the amount of wash water used to remain roughly the same as the current level. Based on customer hearings and dewatering tests, we proposed the CS type (single cloth filter). After implementation, the amount of coagulant used was significantly reduced, and the decrease in moisture content also led to a reduction in disposal costs for the dewatered cake. [Challenges] ■ High running costs due to the use of two types of polymer coagulants (cationic and anionic) ■ High moisture content in the dewatered cake leading to increased disposal costs ■ Preference for the amount of wash water used to remain roughly the same as the current level *For more details, please refer to the PDF document or feel free to contact us.
