Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement needs that require the use of a decanter, it is recommended to prioritize confirming key technical parameters such as treatment flow rate, material corrosion resistance, etc., to ensure that they match the actual load of sewage treatment or industrial processes.
  • In different scenarios such as chemical or food processing, the sealing performance and drainage efficiency of the decanter may become key differences, which need to be evaluated in conjunction with specific application environments.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and enterprises with industry data support or platform statistical information.
  • If the decanter is used for the treatment of high suspended solids wastewater, attention should be paid to the compatibility between the weir design parameters and the automatic control system to avoid frequent blockages or maintenance issues.

Knowledge Base

Q

Scientific Selection and Working Principle Analysis of Decanter In intermittent wastewater treatment processes such as sequencing batch reactor (SBR), the key challenge to ensuring effluent quality is how to efficiently and smoothly discharge the supernatant after the sedimentation stage, while avoiding disturbing the settled sludge at the bottom. The decanter is the core equipment designed to solve this technical pain point, and its performance is directly related

Q

Float type decanter is a commonly used equipment for sewage treatment. It is mainly composed of components such as floats, and through a special structure and working principle, it achieves efficient water decanting. It can accurately discharge the supernatant during the sewage treatment process, ensuring the quality of the effluent water. It has the characteristics of unique structure and stable operation, and plays an important role in various sewage treatment processes.
