Sludge that has been activated

An activated sludge treatment method uses oxygen to treat wastewater. The process involves agitating the sewage inside the tank to ensure that the solids are mixed and a rich oxygen mixture is produced. The water is then allowed to settle, ensuring that it is in the right environment for microbes to flourish. The sludge is later treated by filtration to remove dissolved solids and to oxidize organic matter.

Aeration in the conventional manner is the most widely used design for activated wastewater treatment systems. It is more expensive than extended aeration systems however, it can produce acceptable effluent levels. This process is situated in the middle of BOD curve. It is therefore called a middle-of-the-road method. Natural flocculation is another type of process that is more efficient and effective in eliminating BOD and minimizing the amount of sedimentation.

Activated Sludge treatment is a labor-intensive process that requires skilled workers who are knowledgeable about the risks to health associated with handling the effluent. The effluent that is produced during the process shouldn’t be handled directly since this could be a health risk for animals and humans. Before it is released to the environment, the effluent must be treated with appropriate disinfection. Activated sludge systems are ideally located in areas that have a low population density and far from areas that are densely populated.

Membrane bioreactors

Membrane bioreactors are a viable option to treat wastewater. They combine traditional biological processes with advanced membrane filtering. They are utilized in municipal and industrial wastewater treatment systems. Membrane bioreactors are expensive due to their complicated design and technical components. Expert knowledge is required for their installation. This technology is a fantastic alternative to an outdated wastewater treatment plant.

The sMBR technology involves filtration modules located outside the aerobic tank. The aeration system removes organic compounds and provides oxygen to the bacteria. After filtration is completed, biomass is pumped through a bank of membranes and then a second pump. A cleaning tank could be integrated into the system alongside the pump. You can also clean the membranes at-home.

Submerged membrane bioreactors can be installed in the majority of instances. In these systems, the membranes are flat sheets with a pore size between 0.2 to 1 micron. The membrane is able to trap bacteria while keeping solids out. Activated sludge can also be removed by pumping, which increases shear stress on the flocs. Apart from accelerating the growth of bacterial, pumping activated sludge can also increase the foulant material.


Screens are used for various purposes in wastewater treatment systems. They are placed in the plant’s treatment area and contain substances that could block the system and cause damage. Some types of screens are more suitable for specific purposes than others. The STEPGUARD(r) for instance is a stairscreen, which separates large solidsand conveys screenings and is able to clean itself. Another popular type of screen is the DRUMGUARD(r), which is durable and is used in water and sewage applications. Cup screens are commonly used in wastewater treatment facilities. They are made of stainless steel and are utilized for water intakes.

There are a myriad of options of screens for wastewater treatment systems. The type and design of a screen will be contingent on the dimensions and the composition of wastewater treatment systems. A wastewater treatment facility should have screens that can trap large amounts of trash but leave the majority of organics essential to life in the process. Otherwise, trash will clog pumps and float in final clarifiers. Screens can be used to remove the waste-related materials in wastewater and reduce the amount of inorganic substances that are removed from the process.

The selection of a screening method is contingent on the purpose and design of the wastewater treatment process. The screening system’s size will be determined by the amount of solids to be eliminated, the approach velocity of water, the mesh size and the quantity of solids that need to be removed. Screens can also differ in the velocity that is recommended, which could be as low as 30 percent , and up to 50 percent.
