Sewage Treatment Plants
Sewage treatment is the process of removing contaminants from the municipal waste which hold house hold sewage and other industrial contaminants.It is the safe method which involves physical,chemical and biological processes to remove the contaminants and serve treated safe drinking water in to the environment.
Biofilm process is an efficient process when comparing to other treatment method, Moving bed bioflim reactor in general requires less space than activated sludge systems because the biomass is more concentrated, and the efficiency of the system is less dependent on the final sludge separation.
MBBR systems don't need a recycling of the sludge, which is the case with activated sludge systems.The MBBR system is often installed as a retrofit of existing activated sludge tanks to increase the capacity of the existing system. The degree of filling of carriers can be adapted to the specific situation and the desired capacity. Thus an existing treatment plant can increase its capacity without increasing the footprint by constructing new tanks.
Advantages comparing with activated sludge systems,
- Advantages comparing with activated sludge systems,
- Responds to load fluctuations without operator intervention
- Lower sludge production
- Less area required
- Resilient to toxic shock
- Process performance independent of secondary clarifier
(due to the fact that there is no sludge return line)
- Screening and Pumping
- Grit Removal
- Primary Settling
- Aeration / Activated Sludge
- Secondary Settling
- Oxygen Uptake
