Conventional Wastewater Treatment Service provides reliable solutions for treating domestic and industrial sewage using proven biological processes. These systems use the activated sludge process to break down pollutants in wastewater, producing treated water that is safe for discharge or reuse.
While conventional plants require more space than modern MBR systems due to separate activated sludge reactors and sedimentation tanks, they remain highly effective. Tertiary filtration can be added when stricter reuse standards are needed.
A Prefabricated Sewage Treatment System is a ready-to-install solution designed for fast deployment and minimal civil work. Built using durable FRP tanks, these systems are ideal for limited-space sites or projects with tight timelines.
Key Features:
Applications:
Prefabricated systems combine convenience, efficiency, and sustainability, making them a modern choice for wastewater management.
The bar screen is the first line of defense in wastewater treatment. It removes large solids such as rags, sticks, plastic bags, and other debris that may damage or block downstream equipment. By intercepting these materials early, bar screens protect pumps, pipes, and biological treatment units, ensuring smoother operation and reducing maintenance requirements.
After initial screening, wastewater flows into the solid separation chamber. Here, the water slows down, allowing heavier solids to settle at the bottom, while lighter substances like oils and grease float to the surface for removal. This process not only clarifies the water but also prevents excessive load on the biological treatment stages, improving overall efficiency.
The backbone of wastewater treatment is comprised of naturally existing microorganisms. These species, which include bacteria, fungus, protozoa, rotifers, and other microorganisms, live on many of the complex substances found in home wastewater.
Highly engineered bioreactors are used in secondary-treatment procedures in municipal wastewater treatment facilities. These bioreactors are made to give the bacteria the best possible environment so they can help with the repair of domestic wastewater. Aerobic and facultative bacteria can quickly oxidize soluble, bioavailable organic and nitrogenous substances with the mechanical addition of dissolved oxygen.
In the aerobic chamber, naturally occurring microorganisms—including bacteria, fungi, and protozoa—break down organic matter in the presence of oxygen. Mechanical aeration systems supply dissolved oxygen to optimize microbial activity. Aerobic treatment efficiently oxidizes organic compounds, nitrogenous substances, and other pollutants, producing treated water with significantly reduced biochemical oxygen demand (BOD) and chemical oxygen demand (COD).er.
The process of sedimentation involves allowing particles suspended in water to separate under the influence of gravity. In the process of treating water, the particles that separate from the suspension form sediment and are referred to as sludge. Consolidation is the continued settlement of a heavy layer of sediment. Thickening is the process of consolidating silt, or sludge, with the use of mechanical means.
Chlorination is a process used to disinfect wastewater, and it is particularly good in getting rid of bacteria, viruses, and protozoa. Although chlorination is frequently utilized because it can eliminate the majority of pathogenic organisms more successfully than other treatment options, it can also get rid of the majority of other impurities found in water. Chlorination during wastewater treatment can be crucial if you want to get rid of the harmful organisms that can cause waterborne illnesses. Chlorination aids in the elimination of smells that may be given off when wastewater is released into the environment.
To maintain a healthy “food to biomass” (F/M) ratio, excess sludge, also known as “surplus activated sludge” or “waste activated sludge,” is eliminated from the treatment procedure. (where biomass refers to the activated sludge). This sewage sludge typically pumps back to the primary tanks and mixes with primary sludge to go through additional sludge treatments, such as anaerobic digestion, thickening, dewatering, composting, and field application since these sludge is rich in microorganisms.
Sequencing As one cycle of treatment is over, the next batch of wastewater is fed into the tank once more, and the process continues. In a batch reactor, several reaction stages take place in sequence: fill, react, settle, idle. SBR process is suitable for small to medium-sized sewage treatment plants.
Key advantages of SBR include:
Moving Bed Bio Reactor process utilizes attached growth biological process for BOD removal. Due to the high-density population of the different types of bacteria growing in the carriers, MBBR process improves reliability, simplifies operation, and requires less space than traditional wastewater treatment systems.
Benefits of MBBR include:
