The main process technology are:
1. Mechanical filtration removes suspended particles
2. Bio treatment with SPL convert Ammonia and Nitrite into the no poisons Nitrate.
3. Protein skimmer with venturi injection system remove protein, organic compounds,
reduce BOD/COD, fine particles like bacteria and viruses, faces and oxidation products from the ozone treatment. Also dissolved oxygen is increased and pH value is stabilized.
