      Features

      1. To increase OTR(Oxygen Transfer Rate), and reduce Biochemical oxygen demand(BOD) from wastewater treatment.
      2. Mixing and stirring applications result in uniform Mixed Liquor Suspended Solid(MLSS) due to fine bubbles convention.
      3. Dry motor with overload protector; Cable with an epoxy resin sealed water-proof cable hood; Use deep groove C3 bearing to extend life time.
      4. Superior abrasion resistant dual mechanical seals made of SIC material to ensure best seal effect and reduce abrasion from sewage.
      • EFJ is suitable for wastewater containing solid particles.The solid passage of EFJ ejector pump is 35~50mm.
      • EAJ is customized, and it's suitable for sump or wastewater containing tiny solid particles.The solid passage of EAJ ejector pump is only 6mm.
      • Please place the EFJ/EAJ on concrete or a hard surface in the Wastewater Pond. Never sink EFJ/EAJ in mud.

      Applications

      1. Oxygen aeration of wastewater for wastewater treatment.
      2. Oxygenated for aquaculture, such as fishing farming or shrimp farming or hydroponics applications.

      Actual Installation

      • Used in aquaculture farms to increase the oxygen content and dissolved oxygen rate of shrimp ponds or fish ponds.
