Morail Engineering offers STP from 5 cum/day to 10 MLD. The entire treated sewage waste can be recycled after treatment and can be reused for gardening, cooling towers, floor washing, and other non-critical applications. We also offer prefabricated sewage treatment plants of 10 KLD to 50 KLD.

Extended Aeration System

Extended Aeration is a type of activated sludge process with primary settling. It is the most commonly used treatment system in small developments and resorts. In an extended aeration (EA) system, sewage is brought into a biological basin, and degraded by naturally occurring bacteria. After an “extended” period of time, typically 24 hours of detention time, the mixed liquor (ML) is sent to a clarifier where it is allowed to settle. The retention time will be very long to generate less sludge. Secondary effluent (SE) is drawn off the clarifier and the settled biomass is returned to the head of the plant. To maintain a constant mixed liquor concentration, a certain amount of the settled biomass is wasted (WAS) out of the plant, typically to an aerated sludge holding tank.

Membrane Bioreactor

MBR is the combination of a membrane process like microfiltration or ultrafiltration with a suspended growth bioreactor. This very compact arrangement produces an MF/UF quality effluent suitable for reuse applications or as a high-quality feed water source for Reverse Osmosis treatment. The MBR process can be employed in activated sludge processes, using the membranes as liquid-solid separation instead of the usual settling. It has a high separation
property due to transmembrane pressure, which blocks sludge & large molecules in the membrane, letting clear water permeate through.

  • MERITS OF TECHNOLOGY
  • Higher effective Bio reaction
  • Good resistance of impact of Shock Good resistance of impact Shock loads
  • High-quality outlet water
  • Reduced Footprint with aesthetic appearance

Moving Bed Bio‐film Reactor

Moving Bed Bio‐Reactor (MBBR) technology is based on the biofilm principle with an active biofilm growing on small specially designed plastic carriers that are kept suspended in the reactor. It is one of the ads and advanced biological treatment processes which have a great potential for the simultaneous and efficient removal of nutrients along with organic matter. It is a process coupling suspended activated sludge and attached growth process in a single system. The technology utilizes the advantages of both activated sludge and other biofilm systems (e.g. bio‐filters, bio‐rotors, etc.) without being controlled by their disadvantages. The carriers are designed in such a way that it provides a large protected surface area for the biofilm and optimal conditions for the bacteria culture while suspended in the water.

  • MERITS OF TECHNOLOGY
  • Clog-free operation
  • High bio surface area
  • Make the bio system extremely compact
  • No sludge return system is needed

Sequential Batch Reactor

The sequencing batch reactor (SBR) process is a sequential suspended growth (activated sludge) process in which all major steps occur in the same tank in sequential order. The complete five phases take place in a single reactor thus reducing the footprint. SBRs can be designed and operated to enhance the removal of nitrogen, phosphorus, and ammonia, in addition to removing TSS and BOD. The five stages of SBR

  • MERITS OF TECHNOLOGY
  • Lower installed cost than “Conventional” methods
  • Less land space required for SBR treatment plants with low nutrient-level effluent
  • Reduced Footprint with aesthetic appearance
