What is primary treatment of wastewater?
Wastewater treatment is a crucial process that aims to remove contaminants and pollutants from wastewater to make it safe for discharge into the environment or reuse. Primary treatment of wastewater is the first stage of wastewater treatment and involves physical removal of suspended solids and floatable materials from the wastewater. It is a vital step in the treatment process as it reduces the organic content of the wastewater and prepares it for secondary treatment. The primary treatment process can be accomplished by various methods, including screening, sedimentation, and floatation.
Screening is the process of removing large debris and suspended solids from the wastewater. This is typically done using a bar screen, which is a series of metal bars spaced closely together to prevent larger solids from entering the wastewater treatment plant. The removed solids are then disposed of as waste.
Sedimentation, also known as clarification, is the process of allowing the suspended solids to settle at the bottom of a settling tank. The solids that settle at the bottom of the tank are referred to as sludge and must be removed regularly to maintain the efficiency of the treatment process. The clear liquid that rises to the top of the tank after sedimentation is called the clarifier supernatant and is then sent to the secondary treatment stage.
Floatation is a process that uses chemicals, such as alum, to cause the floatable solids to clump together and float to the surface of the wastewater. The floatable solids are then removed, and the clear liquid is sent to the secondary treatment stage.
Primary treatment of wastewater is a critical step in the overall treatment process as it reduces the organic content of the wastewater and removes floatable materials and suspended solids. This helps to improve the efficiency of the secondary treatment stage and also reduces the potential for blockages and other problems in the discharge pipes.
Primay treatment of wastewater is essential for achieving effective and efficient wastewater treatment. The primary treatment process involves screening, sedimentation, and floatation, which are used to remove suspended solids, floatable materials, and contaminants from the wastewater. These steps help to reduce the organic content of the wastewater and prepare it for secondary treatment. Additionally, primary treatment helps to prevent blockages and other problems in the discharge pipes, ensuring the safe and sustainable discharge of treated wastewater into the environment.
It is important to note that primary treatment alone is not enough to make wastewater safe for discharge into the environment or reuse.
What is secondary treatment of wastewater?
Secondary treatment of wastewater is a stage in the wastewater treatment process that follows primary treatment. Secondary treatment is necessary to remove the remaining pollutants and contaminants, including dissolved and colloidal solids. The most common methods of secondary treatment are biological treatment processes, such as activated sludge and biofilters.
Activated sludge is a process that uses microorganisms to break down the remaining organic matter in the wastewater. The microorganisms are maintained in a tank, where they consume the organic matter and produce biomass, which is then removed and treated as sludge. The clear effluent from the activated sludge process is then sent to the tertiary treatment stage.
Biofilters use microorganisms growing on a substrate, such as gravel or sand, to break down the organic matter in the wastewater. The wastewater is trickled over the substrate, where the microorganisms consume the organic matter and produce biomass, which is then removed and treated as sludge. The clear effluent from the biofilter process is then sent to the tertiary treatment stage.
Tertiary treatment is the final stage of wastewater treatment and is designed to remove any remaining pollutants and contaminants. Tertiary treatment processes may include filtration, disinfection, and nutrient removal.
Filtration involves passing the effluent through a physical filter, such as a sand filter, to remove any remaining solids. Disinfection involves adding a chemical, such as chlorine, to kill any remaining pathogens in the wastewater. Nutrient removal is a process that removes excess nutrients, such as nitrogen and phosphorus, from the wastewater to prevent eutrophication, which is the excessive growth of algae and other aquatic plants in a body of water due to an increase in nutrient levels.
Primary treatment of wastewater is a critical step in the overall treatment process. It involves the physical removal of suspended solids and floatable materials from the wastewater, which helps to reduce the organic content of the wastewater and prepare it for secondary treatment. Secondary treatment is necessary to remove the remaining pollutants and contaminants, including dissolved and colloidal solids, and may involve biological treatment processes, such as activated sludge and biofilters. Tertiary treatment is the final stage of wastewater treatment and is designed to remove any remaining pollutants and contaminants, including filtration, disinfection, and nutrient removal. Effective and efficient wastewater treatment is crucial for ensuring the safe and sustainable discharge of treated wastewater into the environment.

What are MBBR sewage treatment plants?
MBBR (Moving Bed Biofilm Reactor) sewage treatment plant is a wastewater treatment technology that utilizes a combination of physical and biological processes to treat and purify wastewater. The process is based on a suspended growth biological treatment system that uses biofilm carriers to provide a large surface area for the growth of microorganisms.
In an MBBR sewage treatment plant, the wastewater is pumped into a reactor tank that contains a large number of biofilm carriers. These carriers are specially designed plastic media that provide a large surface area for the growth of microorganisms. As the wastewater flows over the biofilm carriers, the microorganisms present on the carriers feed on the organic matter in the wastewater, breaking it down into simpler compounds.
In the MBBR process, the biofilm carriers are kept in constant motion using aerators or agitators, which also help to oxygenate the wastewater. The constant movement of the carriers helps to maintain a high level of mixing and keeps the biofilm from becoming overloaded or clogged.
The treated wastewater then flows from the reactor tank to a secondary clarifier, where any remaining solids are separated and removed. The clear, treated wastewater is then disinfected, typically using chlorine or ultraviolet light, before being discharged into the environment.

How is chemical treatment of wastewater done?
Wastewater treatment typically involves a series of physical, chemical and biological processes to remove contaminants and impurities. Chemical treatment typically involves adding chemical reagents to the wastewater to change the pH or to remove specific contaminants.
- Neutralization: Neutralization is the process of adjusting the pH of the wastewater to a neutral level (usually 7.0) by adding chemicals such as sodium hydroxide (NaOH) or sulfuric acid (H2SO4). This helps to prevent corrosion in pipes and treatment equipment and to improve the effectiveness of other treatment processes.
- Coagulation and flocculation: Coagulation and flocculation are chemical processes used to remove suspended solids and colloidal particles from wastewater. Coagulants, such as aluminum sulfate (Al2(SO4)3) or ferric chloride (FeCl3), are added to the wastewater to destabilize the suspended particles and cause them to clump together (flocculate). The larger clumps of particles can then be more easily removed through sedimentation or filtration.
- Precipitation: Precipitation is a chemical process used to remove dissolved heavy metals, such as lead and copper, from wastewater. Precipitant chemicals, such as lime (CaO) or sodium hydroxide (NaOH), are added to the wastewater to cause the heavy metals to form solid precipitates that can be removed by sedimentation or filtration.
- Adsorption: Adsorption is a process that uses activated carbon to remove dissolved organic contaminants from wastewater. The activated carbon has a large surface area that attracts and binds organic molecules, removing them from the wastewater.
- Oxidation: Oxidation is the process of removing dissolved organics, sulfur compounds, and some inorganic compounds from wastewater using chemical or biological oxidants. Chemical oxidation involves adding chemicals, such as hydrogen peroxide or ozone, to the wastewater to oxidize and remove the target contaminants. Biological oxidation involves adding bacteria or other microorganisms to the wastewater that can oxidize the contaminants through biological processes.
