EPS Biochamber BK450

• Dimensions: 138 x 78 x 103 cm • Number of inlets: 4 x 110 mm • Number of outlets: 4 x 110 mm • including ventilation plate • including cover In the pump version (if interested, we can also provide in the gravity model) The unprotected surface is the inner and outer surface of the filter media. The protected surface means that only the inner surface of the filter material is protected. In the moving bed process, the filter material moves through the air and moistens each other. As a result, bacteria outside are collected on the filter material again and again. When choosing a filter material, it is important to pay attention to the protected surface during the moving bed process. In order to prevent high contamination of the filter material, it is very important to prevent good mechanical water purification (drum filter, slot filter, paper, etc.). Effective entanglement of the filter material is possible by filling only 40% of the water volume with filter media. We recommend Helix or Aquawise. Does not contain filter material.
