Although conventional treatment plants require more space when compared to other technologies, the operation of this type of plant is much easier.
Expert knowledge is unnecessary to operate conventional plants. We use locally manufactured / local equipment when constructing conventional plants. Wikipedia
The Sequencing Batch Reactor (SBR) is an activated sludge process working in a batch mode with aeration and sludge settlement both occurring in the same tank. This leads to a reduction in civil costs and less space is required as several steps are occurring in the same tank. Wikipedia
Moving Bed Biofilm Reactor (MBBR) process requires less space than conventional waste water treatment Systems. MBBR technology uses polyethylene biofilm media which is kept in suspension in an aeration tank. The effluent from the MBBR stage should be further clarified using a clarifier.
When compared with conventional systems, MBBR requires less space, that leads to a considerable reduction of civil costs. Wikipedia
Membrane Bio Reactors is the latest technology in the waste water treatment field. The Membrane bio reactor technology consists of a membrane unit submerged in a suspended growth bio reactor. The membrane acts as an efficient filter, which reject the solid materials generated in the biological process and allowing the treated water to pass through.
High quality output is generated from MBR plants. Wikipedia
SHP is focused on reducing on sludge weight & volume
Reduces cost of disposal
Mitigates potential health risks
The RBC process consists of a special biological reactor that contains a series of large discs, mounted on a slowly rotating shaft. The disc assembly is immersed in waste water and 40 % of the surface area is submerged.
RBCs have low power requirements compared to other treatment methods, this leads to lower operating costs. Wikipedia
