Moving Bed Bio Reactor (MBBR)

Moving bed bio-reactor (MBBR) system is a biological treatment system consisting of aerobic bio-reactor (aeration tank) followed by secondary clarifier along with return sludge system. Aerobic bio-reactor in moving bed bio-reactor system employs both attached growth type and suspended growth type micro-organisms for removal of organic matter by microbial activity and hence floating type media provided in the contents of aerobic bio-reactor to enable attached growth type micro-organisms to grow on it’s surface.

Aerobic Bio-Reactor ( Moving Bed Bio Reactor - MBBR based Aerobic Biological Treatment System).

Screened, equalized and de-oiled sewage first enters the Aerobic Bio-Reactor which is be the first unit of the biological treatment system. The biological treatment system will comprises of hybrid type MBBR based Aerobic Bioreactor with floating type of media utilizing attached growth type of micro-organisms grown on floating media and suspended. The Aeration tank will be followed by hopper bottom secondary clarifier for removal of organic matter aerobically. The equalized sewage will be taken to the aeration tank which will be the first unit of aerobic biological treatment system. In the aeration tank, organic matter present in the equalized sewage will be destroyed with the help of the microorganisms in presence of oxygen.

Membrane Bio Reactor (MBR)

MBR process is a biological treatment system comprising of aerobic system consisting of bio-reactor i.e. aeration tank followed by MBR tank equipped with submerged MBR membrane cassette for removal of organic matter aerobically.
MBR Membrane acts as a physical barrier to suspended solids, bacteria and majority viruses. Hence produces consistent quality of treated water.

MBR Advantages

• Immersed Hollow fibre Ultra filtration system
• Compact, requires 1/2 to1/3 space for a conventional process
• Modular, Maintenance Free
• Low energy consumption
• Standard modules to treat domestic sewage, primary or secondary waste waters, cooling tower blow down etc.
• Single packaged unit with minimal civil construction
• Retrofitting an existing sewage treatment plant can enhance treatment capacity nearly 3-5 folds

Increasing urbanization and human activities exploits and affect the quality and quantity of the water resources. This has resulted in pollution of fresh water bodies due to increased generation of domestic waste, sewage, industrial waste etc. This paper reviews the Root Zone Treatment System (RZTS) which are planted filter- beds consisting of soil.


This Technology uses a natural way to effectively treat domestic and industrial effluents. RZTS are well known in temperate climates and are easy to operate having less installation, low maintenance and operational costs and incorporates the self-regulating dynamics of an artificial soil eco-system. This technology has been successfully running in several countries like Europe and America. Use of constructed wetlands can now be recognized as an accepted low cost eco-technology, especially beneficial as compared to costly conventional treatment systems. There is a need to exploit this technology in a developing country like India to its maximum to gain its benefits and for sustainable development.

The root zone treatment is a natural maintenance free system where the sewage wastewater is purified by the roots of wetland plants. ... The term root zone encompasses the life interactions of various species of bacteria, the root of the wetland plants, soil, air, sun and of course, water.

Sequential Bio Reactor (SBR)

SBR technology is a method of wastewater treatment in which all phases of the treatment process occur sequentially within the same tank. Hence, the main benefits of the SBR system are less civil structures, inter-connecting pipe work, and process equipment and the consequent savings in capital and operating costs.

Conventional activated sludge systems require separate tanks for the unit processes of biological reactions (aeration of mixed liquor) and solids-liquid separation (clarification) and also require process mixed liquor solids (return activated sludge) to be returned from the final clarification stage to the aeration tanks.

 

All SBR’s operate on a time-based process cycle to achieve the process conditions necessary for carbonaceous oxidation, nitrification, de-nitrification and biological phosphorus removal. In addition, solids-liquid separation, treated effluent removal, and solids wasting are also incorporated to complete the process cycle.

In addition, solids-liquid separation, treated effluent removal, and solids wasting are also incorporated to complete the process cycle.

The various phases in a typical SBR process cycle usually comprise the following:-

• Fill - Wastewater enters the SBR tank and mixes with activated sludge mixed liquor solids within the tank.
• Mixed Fill - Influent wastewater and activated sludge are mixed together to produce anaerobic / anoxic conditions in biological nutrient removal (BNR) systems.
• React - Aeration of the tank contents. Biological reactions occur until the desired degree of treatment has been achieved.
• Settle - Aeration is stopped and the activated sludge solids settle to form a blanket on the base of the reactor vessel, leaving an over-layer of treated effluent.
• Decant - Clarified treated effluent ( supernatant) is removed (decanted) from the tank without disturbing the sludge blanket.
• Idle - Unexpired time between cycles. Wasting of excess activated sludge occurs.

Completion of these phases constitutes a cycle, which is then repeated.

SBR technology has the advantage of being much more flexible than conventional activated sludge processes in terms of matching reaction times to the concentration and degree of treatment required for a particular waste water.
The SBR process allows for the following adjustments to be made in addition to those (such as sludge age and operating mixed liquor solids concentration) that can be made in an equivalent Conventional process

• total cycle duration
• duration of each phase within the process cycle
• pattern of inflow dissolved oxygen profile during aeration
• operating top water level
• operating bottom water level

 

Hence changes in wastewater characteristics over time may be readily accommodated in the SBR process

The growing problems of massive water consumption and pollution, destruction of aquifers, extensive pavement that prevents recharge needs a completely new approach to urban and watershed planning. Natural Reed Bed System (NRBS) technology is to break the problem down into onsite, manageable and economic solutions.
NRBS is a sustainable natural technology for treating sewage and waste streams, rehabilitating affected water bodies and rebalancing watersheds. NRBS is reducing dependence on energy and maintenance, freeing up valuable water resources for on-site usage and most of all restoring nature’s ability to preserve and protect itself.NRBSs are designed as part of the urban green landscape and serve several functions at once: They treat sewage, recharge the aquifer, harvest water, prevent floods, act as green lungs, reduce energy needs for transport of water and eliminate needs for failure-prone piping.

Advantages of NRBS

• Long lasting, self sustaining system.
• Very low maintenance costs with minimal energy involvement using Natural plantations. No by-products such as sludge.
• High endurance under extreme water flows and contaminant loads.
