Product features and performance indicators:
Bubble diameter 30μm~50μm (releaser model can be selected according to different treatment objects); Low pressure operation, dissolved gas efficiency up to 99%, release rate up to 99%; The dissolved efficiency of dissolved air water is 80-100%, which is 3 times higher than that of traditional dissolved air flotation efficiency; The pressure-flow curve is flat, easy to realize automatic control, easy to operate and maintain, and low noise; The hydraulic residence time is short and the land occupation is small. Oil/SS removal rate > 90%.
Principle:
Pond® advection air flotation device organically combines precipitation and air flotation principle, giving play to their respective advantages, applying the precipitation method for dense and heavy impurity particles, and using the air flotation method for light and easy to float impurity particles and grease. This technology solves the disadvantage of using a single sedimentation method to treat water quality that is not up to standard, and adds dissolved air water in the back section of the advection pool, which is equivalent to secondary air flotation, preventing the sinking of oil residue that has floated in the front section, and providing a guarantee for the effluent quality. According to the calculation and research and development, the arrangement of the secondary air flotation release device in the pool is a position where the precipitated impurities can be completely precipitated, and the device is not installed at the bottom of the tank body, which is higher than the bottom mud, so that the dissolved air water released by the secondary air flotation release device does not affect the impurities that have been precipitated and does not produce secondary pollution.
Operating effect and application field:
The installed Pond® advection air flotation device has met the requirements of use, with a high degree of trouble-free automation and high efficiency in removing suspended solids.
Iron and steel, light industry, petroleum, petrochemical, chemical, thermal power, metallurgical oily wastewater; Papermaking, leather, textile printing and dyeing pulp, impurities and color removal; Purification of food, brewing and pharmaceutical materials; Activated sludge concentration such as municipal sewage treatment and reuse.
