Description

Foam separator

Technical Field

The utility model relates to the technical field of aquaculture, in particular to a foam separator.

Background

In the aquaculture of aquatic economic animals, suspended particulate matter is produced and a portion of the organic matter is dissolved in the water. Farms typically use foam separators to separate impurities from the water, which separate the foam by air flotation. In the using process of the foam separator, ozone is generally added to achieve the disinfection and sterilization effects, and in addition, bubbles are generated after the ozone is decomposed, so that the air floatation effect is also generated. Air floatation principle: air floatation is to generate a large amount of fine bubbles in water, and the fine bubbles adhere to small suspended particles in the wastewater.
