Purchasing Guide

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

  • For procurement needs that require the use of vortex concave air flotation machines, it is recommended to prioritize checking key technical parameters such as processing capacity and dissolved air efficiency to ensure compatibility with wastewater treatment scale and water quality characteristics. For example, the paper and printing and dyeing industries need to pay attention to the removal rate of oil and suspended solids.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. Such suppliers' application cases of air flotation machines in the chemical or food processing fields are usually more informative.
  • In different application scenarios such as municipal sewage or industrial wastewater treatment, the aeration system design of vortex concave air flotation machines varies greatly. When purchasing, it is necessary to clarify the influence of parameters such as aeration volume and bubble particle size on the actual effect.
  • In the treatment of high concentration organic wastewater in industries such as petroleum and pharmaceuticals, it is recommended to comprehensively evaluate the corrosion resistance and energy consumption level of the air flotation machine material to avoid affecting long-term operational stability due to insufficient equipment adaptability.
