摘要： A system for effectively removing biochemical oxygen demand (BOD), total suspended solids (TSS), ammonia, total nitrogen (TN), and total phosphorus (TP) from wastewater has integrated multiple physiochemical and biological treatment processes into one unit. This system includes a primary DAF unit, anoxic bio-media treatment zone, and a secondary DAF unit. The bio-media treatment zones may be used to remove BOD and TN and may be divided into a number of functional zones. Each functional zone can develop and accumulate optimized bacteria species and microorganisms based on incoming wastewater BOD and nutrient levels.

摘要： The present invention provides an aquaculture system for rearing aquatic creatures. The aquaculture system includes a rearing tank adapted to contain water for rearing the aquatic creatures, wherein the aquatic creatures produces waste which produces ammonia, a first denitrification apparatus adapted to convert the ammonia to nitrate, such that the first denitrification apparatus includes a least one culture media adapted to culture denitrifying bacteria and is adapted to channel a first water flow from the rearing tank through the first denitrification apparatus and back to the rearing tank, and a second denitrification apparatus adapted to convert the nitrate to nitrogen gas, such that the second denitrification apparatus includes at least one culture media adapted to culture denitrifying bacteria and is adapted to channel a second water flow from the rearing tank through the second denitrification apparatus and back to the rearing tank, such that the first water flow is faster than the second water flow. The present invention further provides a method of rearing aquatic creatures using the aquaculture system.

摘要： The invention relates to a bioreactor having a tank (1) with at least one bioreactor compartment (1a-1c) containing a carrier medium, on the surface of which a biofilm may grow, supply means for supplying the water to be purified into the bioreactor compartment (1a-1c) from the first longitudinal end of the compartment, discharge means at the second opposite longitudinal end of the compartment (1a-1c) for discharging the processed water from the compartment, means (7) for supplying the reaction gas required for the purification process into the bioreactor compartment, and means for agitating the carrier medium and the water to be purified into a rotary motion inside the compartment. In the bioreactor compartment (1a-1c), extending in its longitudinal direction, is arranged a perforated pipe (4), which is at a distance from the inner walls (8, 9) of the bioreactor compartment, and in the inlet end area of which pipe (4) are guide means (2a-2c, 13a- 13c) for guiding the water to be purified into a bioreactor space outside the pipe (4), from which space the purified water enters inside the perforated pipe (4) and discharges from it through the outlet at the outlet end of the bioreactor compartment (1a-1c).

摘要： The present invention is concerned with the development of an intermittent aerated dynamic membrane bioreactor that enables the treatment of wastewater of industries that leaves colored wastewater like textile industry. The invention is a treatment system which enables the anaerobic disintegration of azo group pigments which are difficult to aerobically break down by forming both anaerobic and aerobic conditions in a single reactor and aerobic removal of organic substances which cannot be removed in the anaerobic environment. Providing the air in an intermittent way enables the energy to be used less in comparison to activated sludge systems.
