What is Membrane Bioreactor?

Membrane bioreactors are a technology that is used in wastewater treatment. The MBR combines membrane processes like microfiltration or ultrafiltration with a biological wastewater treatment process, the activated sludge process. These technologies are now widely used for municipal and industrial wastewater treatment. The two basic membrane bioreactors are the submerged membrane bioreactor and side-stream membrane bioreactor. In a submerged membrane bioreactor, the membrane is located inside the biological reactor and submerged in the wastewater, while in a side stream membrane bioreactor, the membrane is located outside the reactor.

Components of Membrane Bioreactor

  1. Membrane Modules

MBR uses ultrafiltration or microfiltration membranes that act as physical barriers to separate suspended solids, microorganisms and pathogens from wastewater.

  1. Biological Reactor

This component provides microorganisms that degrade organic pollutants present in wastewater through aerobic or anaerobic processes.

  1. Aeration System

Aeration is necessary to maintain optimal microbial growth and activity within the biological reactor. It ensures sufficient oxygen supply for aerobic degradation of organic matter.

How do Membrane Bioreactors work?

Membrane bioreactors operate through a combination of physical filtration and biological treatment processes. Wastewater passes through the membrane modules where suspended solids and microorganisms are retained while the treated water filters through the membrane. Concurrently microorganisms in the biological reactor break down organic contaminants, resulting in treated effluent of superior quality.

What is a Sewage Treatment Plant?

Sewage treatment plants are designed to treat and purify wastewater generated by households, industries, and commercial companies. The wastewater includes human and animal waste, food waste, cleaning products, and other contaminants.

The primary objective of a sewage treatment plant is to remove contaminants and pollutants from wastewater so that it can be safely disposed of or recycled for other uses. A sewage treatment plant typically consists of several stages, including primary, secondary, and tertiary treatment.

The primary treatment involves removing heavy solids and organic matter from the wastewater through a physical process such as sedimentation and screening. The secondary treatment is a biological process that includes removing the organic matter using microorganisms. The tertiary treatment, on the other hand, involves removing any remaining contaminants from the water through chemical or physical processes.

Sewage treatment plant manufacturers are essential to maintaining a clean and healthy environment. Untreated wastewater can have a significant impact on human health and the environment. It can lead to the spread of diseases, contaminate soil and water, and damage aquatic life.

Types of Sewage Treatment Plants

There are several types of sewage treatment plants, each with its own set of features and benefits. The most common types of sewage treatment plants include:

Activated Sludge Process (ASP)

The activated sludge process is the most commonly used sewage treatment plant. It involves introducing air into the wastewater to encourage the growth of microorganisms that break down organic matter. The process is effective in removing contaminants such as nitrogen and phosphorus.

The activated sludge process is widely used because it is effective in removing organic components and fertilizers from wastewater, and can be operated with a relatively small footprint. However, it can be energy-intensive due to the need for aeration and can also produce large amounts of excess sludge that require disposal or further treatment. As a result, modifications to the process, such as the use of advanced treatment technologies or the implementation of a sludge reduction program, may be necessary to optimize its performance and reduce its environmental impact.

Activated Sludge Process

Extended Aeration Process (EAP)

The extended aeration process is similar to the activated sludge process, but it involves a longer retention time. This allows the microorganisms to break down the organic matter more effectively, resulting in a higher quality of effluent.

The extended aeration process is known for its ability to produce high-quality effluent, even under variable or low wastewater flow conditions. It also typically requires less energy than other types of activated sludge processes, as the slower rate of microbial growth and longer aeration time results in less oxygen demand. However, the extended aeration process may require a larger footprint due to the larger aeration tank required and can produce more sludge than other processes, which may require additional handling and disposal.

Extended Aeration Process

Sequential Batch Reactor (SBR)

The sequential batch reactor is a batch process that involves alternating between anoxic and aerobic conditions. This process allows for the removal of nitrogen and phosphorus from the wastewater.

SBRs can operate using either aerobic or anaerobic conditions, depending on the specific treatment needs. In the aerobic SBR, air is provided to the tank during the reaction phase to provide oxygen for the microorganisms. In the anaerobic SBR, the treatment occurs in the absence of oxygen, allowing anaerobic microorganisms to break down organic matter.

Sequential Batch Reactor

Membrane Bioreactor (MBR)

The membrane bioreactor combines biological treatment with membrane filtration to produce high-quality effluent. The process is efficient in removing solids and contaminants from the wastewater.

MBRs can use either submerged or external membrane filtration. Submerged MBRs place the membrane directly into the aeration tank, while in external MBRs, the membrane is placed in a separate tank and the mixed liquor is pumped through the membrane.

Membrane Bioreactor

Moving Bed Biofilm Reactor (MBBR)

The moving bed biofilm reactor involves attaching biofilm to plastic carriers that move freely in the wastewater. The process is effective in removing organic matter and nitrogen from the wastewater.

In an MBBR, wastewater flows through a reactor tank containing the suspended biofilm carriers, which provide a surface for the growth of microorganisms. The aeration or mixing of the wastewater ensures that the biofilm carriers are constantly moving and in contact with the wastewater, which promotes the growth of the microorganisms on their surface.

As the wastewater flows through the reactor, the microorganisms on the biofilm carriers consume organic matter, converting it into biomass and other byproducts. The treated wastewater is then discharged, while the biofilm carriers are recycled back to the reactor tank.
