Novel Biological Treatment Package



Nilfam Engineering Company is proud to present the invention of novel biological wastewater treatment packages with consolidated growth by using the knowledge of experts, specialists and executives with a long history of this company. The packages are in two forms, metal and polyethylene, which are designed and implemented using the latest wastewater treatment technology based on the conditions defined in the project. After being directed to this system and performing various purification steps, wastewaters are purified into clear, odorless and free of suspended substances. The evaluation of the output of the packages shows compliance with the standards of the Environmental Protection Organization (international and national). Therefore, can be used for emptying into absorbent wells and for purposes such as green space irrigation.




Advantages of novel biological wastewater treatment packages

The following points can be mentioned regarding the level of technology of novel biological wastewater treatment packages

  •  The quality of the effluent from this companys products (including COD, BOD5, TSS, color, odor, nitrate, phosphate, turbidity) are completely in accordance with the standards of the Environmental Protection Organization.
  •  The hydraulic regime of the flow has been designed and implemented according to the experimental results and the first order of biological reactions in aerobic bioreactors of the type of piston flow (Plug Flow).
  • According to the technology used in these products, the sledge retention time (SRT) in aerobic bioreactors is higher than 20 days and there is no need for aerobic and anaerobic digesters to digest excess sludge.
  • The space required for the implementation of novel biological wastewater treatment packages is at least 50% less than the conventional process. Reducing the size and volume of tanks has a significant effect on reducing energy consumption, so that energy consumption has been optimized by at least 30%.
  •  These packages are odorless and noiseless and have been used in urban areas in the vicinity of residential houses in order to provide water needed for green spaces and irrigation of unproductive trees.
  • All electromechanical equipment is designed and implemented in the corridors between the packages, and there is no need to construct side and industrial buildings for the electrical room and the room it is not blowers.
  •  The sandblasting and painting protocols of this company according to international standards have made the products of this company resistant to the corrosive environmental conditions of wastewater, including oxygen, microorganisms, impure water and sunlight, and have increased the useful life of the products up to 20 years.
  • Structural analysis of the tanks of the novel biological wastewater treatment packages with the most up-to-date related software is aimed at increasing the structural strength and reducing the weight of metal structures and making the products economical.
  •  Modeling of the novel biological wastewater treatment packages with specialized software in order to optimize the process includes reducing hydraulic retention time and increasing hydraulic shockability and increasing organic load and increasing the efficiency of removing pollutants in manufactured products.
  •  These packages are designed and produced for all industrial wastewater separately and according to the industry used and the type of wastewater.
