Sewage treatment. Sewage treatment involves a more complex set of procedures than are needed for water purification because the volume of organic matter and the variety of microorganisms are much greater.

The first treatment, or primary treatment, of sewage and wastewater involves the removal in settling tanks of particulate matter such as plant waste. The solids that sediment are strained off, and the sludge is collected to be burned or buried in landfills. Alternatively, it can be treated in an anaerobic sludge-digesting tank, as follows.

During the secondary treatment of wastewater and sewage, the microbial population of liquid and sludge waste is reduced. In the anaerobic sludge digester, microorganisms break down the organic matter of proteins, lipids, and cellulose into smaller substances for metabolism by other organisms. Results of these breakdowns include organic acids, alcohols, and simple compounds. Methane gas is produced in the sludge tank, and it can be burned as a fuel to operate the waste treatment facility. The remaining sludge is incinerated or buried in a landfill, and its fluid is recycled and purified.

MBBR

MBBR biofilm technology is based on specially designed plastic biofilm carriers or biocarriers that are suspended and in continuous movement within a tank or reactor of specified volume.

The industrial and municipal wastewater is led to the MBBR treatment reactor where biofilm, growing within the internal structures of the biocarriers, degrade the pollutants. These pollutants that need to be removed in order to treat the wastewater are food or substrate for growth of the biofilm. The biocarrier design is critical due to requirements for good mass transfer of substrate and oxygen to the microorganisms and there is a continuous R&D in the area of the MBBR biofilm technology . Excess biofilm sloughs off the biocarrier in a natural way.

An aeration grid located at the bottom of the reactor supplies oxygen to the biofilm along with the mixing energy required to keep the biocarriers suspended and completely mix within the reactor.

Treated water flows from reactor through a grid or a sieve, which retains the MBBR biocarriers in the reactor. Depending on the wastewater, the reactors are may be equipped with special spray nozzles that prevent excessive foam formation.

APPLICATIONS

  • Municipal Wastewater Treatment (Residential facility, Hotels, Hostels, and Resorts)
  • Remote mining, logging, and construction sites
  • Low Flow / High Strength and High Flow / Low Strength application
  • Biological treatment for industrial wastewater flows like Refineries, Food Processing Plants etc.
  • Manufacturing facilities, power plants, military bases
  • Schools and other educational campuses

MBR

Membrane technology has led to a revolutionary new concept in wastewater treatment. Membranes act as a barrier to bacteria and suspended solids to produce a low turbidity treatment plant effluent with very low bacteria counts.

MBR is the combination of a membrane process like microfiltration or ultra filtration with a suspended growth bioreactor. This very compact arrangement produces a MF/UF quality effluent suitable for reuse applications or as a high quality feed water source for Reverse Osmosis treatment

Advantages

  • Reduced plant footprint as Secondary clarifiers and tertiary filtration are eliminated
  • Footprint can be further reduced because other process units (digesters or UV disinfection and aeration basin volume) can also be eliminated/ minimized
  • Long sludge age, hence low sludge production
  • Produces a MF/UF quality effluent suitable for reuse applications
  • Can be housed in a building
  • Reduced sludge dewatering cost
