Sewage Treatment Plant

sewage treatment plant in Bahrain

Sewage is generated by residential, institutional, commercial and industrial establishments. It includes household waste liquid from toilets, baths, showers, kitchens, and sinks draining into sewers. In many areas, sewage also includes liquid waste from industry and commerce. The separation and draining of household waste into grey water and black water is becoming more common in the developed world, with treated grey water being permitted to be used for watering plants or recycled for flushing toilets.

Sewage Treatment Plants (STPs) are supposed to make the municipal sewage compatible for disposal into the environment (surface and underground water bodies or land), to minimize the environmental and health impacts of the sewage, and to make the sewage fit for recycling and reuse (agricultural and aqua-cultural uses and municipal and industrial uses).

Wastewater treatment is closely related to the standards and/or expectations set for the effluent quality. Wastewater treatment processes are designed to achieve improvements in the quality of the wastewater.


sewage treatment plant in Bahrain MBBR (Moving Bed Biofilm Reactor) technology is a compact biological treatment that requires suspended solids separation downstream, with or without chemicals addition.

MBBR biofilm technology is efficient, compact and easy to operate. It can be an excellent solution as a stand-alone process, a Moving Bed biofilm reactor, or it can be used to specifically enhance or upgrade treatment potential of activated sludge processes.

This technology provides cost-effective treatment with minimal maintenance since MBBR processes self-maintain an optimum level of productive biofilm. Additionally, the biofilm attached to the mobile biocarriers within the system automatically responds to load fluctuations.

Benefits of MBBR system:

  • Self regulating biomass
  • Flexible Design that allows for
  • Increased capacity.
  • No operational adjustments, only
  • Equipment maintenance.
  • Stable under large load variations.
  • Smaller foot prints.
  • Low investment Cost.
  • Single pass treatment.
  • Multiple applications
  • Extremely compact and simple biological treatment system.


sewage treatment plants in BahrainMBRMembrane Bio-reactor (MBR) is a process that combines a membrane ultra/micro filtration process and activated sludge process. designed for numerous municipal and industrial applications. Membrane bioreactor systems may be used in such applications as water reuse, new housing developments, parks and resorts, retrofits, and turnkey projects. The need to recycle wastewater and stricter environmental regulations make a membrane bioreactor (MBR) system a viable solution for current and future wastewater treatment. We make MBRs for large municipal wastewater applications that can be fit into concrete tanks, package plants for smaller flows, new developments and hotels as well as a system developed for the petroleum industry to meet most refinery standards.

Benefits of MBR System:

  • Compared to conventional treatment, MBR technology has the benefit of giving an effluent with lower concentration of lipophilic metabolites.
  • The advantage of MBR in comparison with other investigated processes is high unit-volume removal rate.
  • High sludge ages
  • Aerated MBR offers two major advantages in the elimination of phosphorus: complete removal of all particles and aeration, which prevents the phosphate release that occurs under anoxic conditions.


sewage treatment plant in BahrainSAF is one of sewage treatment technology under our main department Dema&C.

Dema&C Submerged Aerated Filter has few moving parts, requires very little maintenance, and is easy to operate. Effluent water is achieved after clarification. SAFs require no regular operator attendance, and are generally used for installations up to 3,000 P.E.

Dema&C SAFs will give many years of service. They can be located above or below ground.

Benefits of a SAF:

  • Lower process air requirements than traditional activated sludge processes.
  • Small footprint.
  • Low head loss solution.
  • Simple to install, minimal connections required on site.
  • Provides stable operation where conventional treatment may be subject to operational stresses.
  • Designed to be mobile, can be moved between sites.
  • Blowers and control panel are mounted on a portable, pre-wired skid.
  • Can be rented or leased to work within capital expenditure budgets.
  • Low operating cost and maintenance requirements.
  • Uses recycled plastic.


sewage water treatment

Sequential batch reactors are industrial processing tanks for the treatment of wastewater. SBR reactors treat wastewater such as sewage or output from anaerobic digesters or mechanical biological treatment facilities in batches. Oxygen is bubbled through the wastewater to reduce biochemical oxygen demand (BOD) and chemical oxygen demand (COD) which makes the effluent suitable for discharge to surface waters or for use on land.
