STPCH1MBBR application field and working principle

STPCH1MBBR (Sequencing Batch Reactor) is a special type reactor which performs various reactions, including anaerobic, aerobic, nitrogen removal, and phosphorus removal. It is used in a wide range of applications, such as wastewater treatment, reclaimed water treatment, and industrial waste treatment. In addition, it has been applied in many energy recovery processes such as biogas generation, water treatment, and zero depletion projects.

STPCH1MBBR is a simplification of a biological waste water treatment system and its performance is based on a sequence of operational steps. The reactor basically consists of a suspended biomass in a basin, over which wastewater is distributed and agitated, allowing oxygen transfer and the uptake of nutrients from the liquid. The primary objective of the reactor is to reduce contaminants from the wastewater, such as suspended solids, BOD and COD, ammonia, and phosphorus through removal by the biomass or by way of chemical reaction.

The process begins with the wastewater being poured into the basin, where it is mixed and exposed to oxygen. This allows for the growth and development of the bacteria in the reactor. The activation biomass in the reactor can then reduce the contaminants, such as BOD, through the process of biological oxidation. The aeration and mixing of the wastewater also allow for the uptake of nutrients, such as nitrogen and phosphorus, by the biomass. Once biomass uptake of the contaminants such as BOD and COD has been completed, the wastewater is dried out and the process is repeated in batches. This looping through of wastewater provides a continuous waste treatment process.

The STPCH1MBBR process is also adaptable to other forms of contaminant removal such as chemical and physical removal processes. Chemical removal of contaminants can be accomplished through the addition of chemicals such as chlorine or ozone to the reactor. These chemicals react with the contaminants in the effluent, resulting in the neutralization or destruction of the pollutants. Physical removal processes, such as sedimentation and filtration, can be incorporated into the reactor to further remove contaminants that the bacteria are unable to metabolize or that require a physical removal process.

In conclusion, STPCH1MBBR is a highly efficient and cost effective wastewater treatment system that can be used for a wide variety of applications. Its ability to incorporate biological, chemical, and physical removal processes allows it to effectively reduce contaminants in wastewater, while its low operational costs make it a very attractive choice for wastewater treatment plants.
