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 plants 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.

Whats-is-Commonly-Used-Sewage-Treatment-Plants-and-its-technology-in-India.jpg

A sewage Treatment Plant (STP) is a process of purification of Sewage water and reusing it for Gardening, Agricultural, and other general Purpose.

Treated Sewage water is purified and maintained as per the Pollution control board norms. STP is mandatory in most industries, housing colonies, apartments, etc. STP is equipped with high Precision components with advanced technology.

Many are confused between STP & ETP. While Effluent Treatment Plant (ETP) is a mechanism or process used to treat the wastewater prior to release into the environment or its reuse. A sewage Treatment Plant (STP) is the process of removing contaminants from wastewater and household / industrial sewage, both runoffs (effluents)

In Detail: Difference Between STP & ETP

Following are a few STP processes & Systems commonly used in India.

Activated Sludge Process
Moving Bio Bed Reactor (MBBR)
Membrane Bio Reactor (MBR)
Electro Coagulation System
Sequential Bio Reactor (SBR)
Rotating Bio Reactor (RBC)

Among the above system, the most commonly used system presently in the market are below:

SBR-Sequencing Batch Reactor– is an activated sludge process used for waste-water treatment. To reduce the organic matter, oxygen is bubbled through the mixture of wastewater and activated sludge.

MBR-Membrane Bio Reactor – is the combination of the membrane process and a biological waste-water treatment process. It is one of the most widely used processes.

MBBR-Moving Bed Biofilm Reactor – is a biofilm process that requires less space than activated sludge systems. This process was invented in the late 1980s.

MBR and SBR sewage water treatment systems are activated sludge processes. But when we talk about differences – the method used in both the processes to separate the liquid from the treated wastewater is different. The technology used by SBR is phase separation which is the gravity setting method. In contrast, MBR uses the membrane – and the use of a physical barrier for separation gives more importance to this process as it increases the advantages.

The other difference is the ability of the sewage treatment plants to operate at high biomass concentrations for mixed liquor suspended solids (MLSS). The MBR treatment plant is considered to overpower others here as it operates at an MLSS of around 12,000 mg/l. On the other hand, the SBR treatment plan works at 3,000 mg/l. The advantage that MBR provides because of this is it takes smaller process basins as compared to others – overall resulting in a smaller plant footprint (around 50-70%) as compared to the SBR process.

Less turbidity is a sign of clean water. MBR has less than 0.2 NTU effluent turbidity – Another benefit that MBR provides. It reduces the burden on the ultimate disinfection system. At the time of operation, the membrane opening is less than 0.xn--1m-99b – and without dis-infection, it has the capacity to achieve 6-log dismissal of bacteria and 3-log of the virus. SBR system cannot get values this low. Here, the usual membrane opening is 10μm which is quite large.

MBR requires less involvement of the operators as the process is quite easy. Many of the plants require operators to keep an eye on the task of settling characteristics of the sludge – keeping in mind all the factors involved here. along with the analysis, adjustments have to be made to keep it settled. Lack of this process can affect the effluent quality.

Another difference is the amount of waste sludge produced by the plants. Again, because of the ability to operate at a much higher sludge retention time, the MBR system tops the chart with lesser waste sludge than SBR.

When we talk about the MBBR process – it requires less space than the activated sludge systems because of the concentrated biomass. Moreover, the efficiency of the system is less dependent on the final sludge separation. Unlike activated sludge systems, MBBR does not require recycling of the sludge. Other advantages include – high effective sludge retention time and lower sludge production.

We see some differences in the treatment plants. However, if there are no restrictions on the footprints and a project doesn’t require any reuse – SBR is a good system. It is cost-effective and takes care of the process required. On the other hand, for reduced footprint and higher quality effluent, MBR is considered the better choice. While MBBR STP is also a consideration for many municipal and industrial waste-water treatment processes.

What is sewage treatment plant?

Sewage Treatment Plant (STP Plant) is a combination of machines, biologicals and chemicals. Which is used to treat human waste and wastewater waste generated from residential, institutional, commercial and industrial establishments. A sewage treatment plant operates by circulating air to encourage the growth of bacteria to break down sewage. The goal is to deliver much cleaner, more environmentally friendly effluent. It involves a similar process to a typical septic tank but has some key differences.

What Are The Stages of Sewage Treatment?

The general construction of a sewage treatment manufacturer doesn’t differ too drastically from that of a septic tank. Just as with a septic tank, sewage flows from the property being serviced into the first chamber of the sewage treatment factory. Then, the water sits until grease, oil painting and proletariat have floated to the top and solids have settled on the bottom of the tank.
Once the process of separation has taken place, the liquid peregrination into a alternate chamber which is where sewage treatment shops differ from septic tanks. This chamber is fitted with an air pump that circulates air around the chamber to encourage the growth of aerobic bacteria. This bacteria helps to break down the pollutants in the water, effectively drawing it.

The final stage of a sewage treatment plant is one last agreement tank. This final tank allows the veritably last solids that may remain to Gomorrah to the bottom of the tank before the effluent is discharged into a soakaway or watercourse.
Once the treatment process has been completed and the wastewater has been treated as completely as possible, it can be discharged into the terrain. This is another crucial area where sewage treatment shops differ from sewage treatment shops. Whereas you must discharge effluent from a septic tank into a soakaway for farther treatment in the ground, subject to an Environment Agency Consent to Discharge, you can discharge your effluent into original water sources straight from your treatment factory. This is because of the extensively bettered effluent quality that the treatment process produces.

Why Are Sewage Treatment plants needed?

The first study for anyone planning a new development should be getting connected to mains seamsters. They’re generally the most cost-effective and dependable system of dealing with your wastewater. still, getting a mains semester connection is n’t always possible. In some scripts, the distance from the nearest seamster or the layout of the land can make it insolvable to have your property serviced by a mains seamster. That’s where sewage treatment plants and other druthers come by. The operation of a sewage treatment factory means that you can have one installed nearly anywhere, as long as you have an electrical connection.

Do Sewage Treatment Plant Still Need evacuating?

The purpose of a sewage treatment plants is to treat the wastewater as completely as virtually possible – and, indeed though similar shops can frequently deal with further waste than a septic tank, they will still need evacuating from time to time. Over time, sludge can also make up in the system, so it’s important that a treatment factory is regularly maintained at least formerly a time or as you’re advised by the installer.

Advantages of a Sewage Treatment plant

Reliable and doubtful to encounter problems with only regular conservation
Can be installed indeed on grueling or compact spots
Cost-effective over time, with only installation, power and conservation to pay for.

Disadvantages of a Sewage Treatment Plants

The factory needs a constant force of electricity to run
Will bear professional conservation annually, and in the doubtful event of problems
Design and installation of the system needs to be accepted professionally
As you can see, the biggest disadvantage of having a sewage treatment plant is that you’re counting heavily on conservation from a professional company. This means that you ’ll have to stay for any problems, still doubtful they are, to be resolved, and also makes choosing the supplier of the service absolutely pivotal.
