Purchasing Guide

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

  • For procurement requirements that require the use of dissolved air flotation, it is recommended to prioritize confirming key technical parameters such as processing capacity, dissolved air efficiency, and bubble particle size to ensure the compatibility of the equipment with wastewater treatment or solid-liquid separation scenarios.
  • In industries such as food processing, printing and dyeing wastewater, or petrochemicals, the type of dissolved air flotation should be selected based on water quality characteristics. For example, high oil wastewater should pay attention to surface load and skimming ability.
  • 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.
  • In the actual procurement process of dissolved air flotation, it is recommended to compare the energy consumption data and operational stability indicators provided by different suppliers. Long term usage costs may significantly differ due to design differences.

Knowledge Base

Q

The working principle of a dissolved air flotation machine is to utilize the different solubility characteristics of water at different pressures, and generate microbubbles in water under pressure or negative pressure conditions. These microbubbles enter the flotation tank through a release device and combine with the flocs formed after adding chemicals to the sewage, causing the flocs to float to the surface, thereby achieving the goal of removing pollutants such as suspended solids, colloidal substances, oils, and organic matter

Q

<&order>Municipal sewage treatment plant. Industrial wastewater treatment. Food processing industry. <&order>Textile industry. <&order>Paper industry. Petrochemical industry: Dissolved air flotation equipment can be used to treat suspended solids, oils, and organic matter in petrochemical wastewater, meeting environmental protection requirements. Dissolved air flotation equipment can be used to treat suspended solids, organic matter, and drug residues in pharmaceutical wastewater.

Q

The vertical flow circular dissolved gas pressurized air flotation device achieves effective removal and separation of pollutants in wastewater through steps such as air dissolution, bubble generation, suspended solids adsorption, and solid-liquid separation. It is an efficient and reliable wastewater treatment equipment. The working principle of the vertical flow circular dissolved gas pressurized air flotation device can be clearly divided into the following steps:
