In order to improve the quality of treatment, increasing the treatment capacity and to be a total solution for environment protection we are coming up with a new concept.
According to type of sewage flow, required treatment process type and environmental conditions, has developed Prefabricated Treatment Packages utilizing Moving Bed Biological Reactor (MBBR) Process and Sequencing Batch Reactor (SBR) Process for sewage biological treatment which incorporate the best technologies in portable treatment systems.
When number of microorganisms grow on surfaces of moving parts, they are called Bio-film. In Moving Bed Biofilm Reactor technology, the Bio-film grow, in the protected way, on engineered plastic packing with high internal surface area, which are freely suspended, thorough mixed through the liquid phase and in continuous movement within the reactor of specified volume, degrade the contaminant. These contaminant that need to be removed in order to treat the wastewater are food for growth of the Bio-film. Therefore, the Bio-carrier design is critical due to requirements for sufficient transfer of food and oxygen to the microorganisms. The Bio-carriers are usually made of polypropylene (PP) and have specific gravity somehow alike wastewater.
Engineered design of aeration systems of the reactor supplies oxygen to the Bio-film along with the mixing energy required to keep the Bio-carriers suspended and completely mixed within the reactor.
Aerated water flows from reactor through a grid or a sieve, which retains the Bio carriers in the reactor. In order to remove the sloughed off biomass from the aerated wastewater, sedimentation is employed after the aeration tank.
Sequential batch reactor (SBR) is nothing but the batch operation in sequence. SBR is a fill-and-draw activated sludge system for wastewater treatment. In this system, wastewater is added to a single “batch” reactor, treated to remove undesirable components, and then discharged.
The unit processes of the SBR and conventional activated sludge systems are the same. The SBR is no more than an activated sludge system which operates in time rather than in space. The difference between the two technologies is that the SBR performs biological treatment, and secondary clarification in a single tank using a timed control sequence. In a conventional activated sludge system, these unit processes would be accomplished by using separate tanks.
