What is MBBR STP?

STP refers to a sewage treatment plant designed to process wastewater generated from both residential and industrial sources. This wastewater undergoes treatment through a multi-stage system known as STP, which has evolved significantly over time, with MBBR being one of the latest advancements.

MBBR presents a cost-effective solution for wastewater treatment plants in regions where environmental regulations are less stringent. It employs biological treatment methods, facilitating both nitrification and denitrification within the tanks. Nitrification involves the transformation of ammonium into nitrate, while denitrification occurs as oxygen is metabolized, converting nitrate into nitrogen.

What is MBBR and How does it function?

MBBR (Moving Bed Biofilm Reactor) is a biological method that utilizes microorganisms or nematodes to break down organic waste present in the water. These microorganisms consume the waste and produce simpler substances that can be easily removed in subsequent treatment stages. Biological wastewater treatment is highly effective and can be implemented as a standalone solution or as part of a larger process. The system includes an activated sludge process, an aeration mechanism, and a biofilm process. Sludge accumulates on plastic carriers, and an increased surface area allows for enhanced air, water, and bacterial interaction, thereby accelerating the treatment process.

Components utilized in the MBBR wastewater treatment process include:

Basin: An aeration tank is equipped with thousands of polyethylene media that serve as a substrate for the growth of microorganisms. The dimensions of the tank and the number of plants are determined by the volume of water treated daily. Typically, two tanks are employed to facilitate the complete aeration process. The MBBR media are designed in round or wheel shapes, with a density that is compatible with water, allowing them to neither sink nor float.

Media: The MBBR tanks are filled with thousands of small, circular polyethylene chips, which occupy approximately 60–70% of the tank's volume. These chips provide a substantial surface area for biofilm development.

Aeration Grid: This component facilitates the effective movement of media throughout the tank and introduces air into the water, creating bubbles that promote proper mixing. Air is delivered through a blower, which pushes it through a pipeline to the diffusers.

Sieve: This element prevents the MBBR media from exiting the tank.

MBBR Sewage Treatment Plant

The Moving Bed Biofilm Reactor (MBBR) sewage treatment plant represents a straightforward and dependable approach to wastewater treatment. Its operational simplicity and ease of management make it superior to traditional methods. The MBBR system employs a collection of polyethylene biofilm carriers that move freely within the aerated basin containing wastewater. Each carrier provides an effective surface area for both autotrophic and heterotrophic bacteria, making this system advantageous for supporting a high-density bacterial population. The MBBR system guarantees a high level of reliability and operational ease.

Our MBBR sewage treatment plant is designed to effectively eliminate physical, chemical, and biological contaminants from wastewater generated by kitchens, restrooms, or industrial facilities. We provide a top-tier solution that is cost-effective, user-friendly, and versatile. Whether you opt for MBBR sewage treatment or an underground sewage treatment plant, installation is straightforward and can be accomplished in compact spaces.

Choose Cleantech Water for a premium MBBR sewage treatment plant and benefit from reliable, low-maintenance services.

MBBR harnesses the combined advantages of various biological processes, incorporating both an activated sludge process and biofilm media. While capitalizing on the benefits of these biological methods, MBBR adeptly addresses the challenges associated with wastewater treatment.

This technique employs plastic carriers that are coated with biofilm to facilitate the breakdown of waste. In addition to effectively removing organic materials, MBBR has demonstrated its capability in supporting nitrification and denitrification processes. The MBBR wastewater treatment procedure consists of several stages, allowing for customization to meet specific purification needs.

Process of MBBR Sewage Treatment Plant

The operation of the MBBR Sewage Treatment Plant involves several key components, including the basin, media, aeration grid, and sieve, which facilitate the various phases of wastewater treatment.

The basin, referred to as the reactor, is the primary site for the MBBR process. Its dimensions are determined by the filtration requirements of the plant. The basin is open at the top, allowing air to interact with the water, which characterizes the MBBR process as an aerobic filtration method. Wastewater, or influent, enters the basin for treatment and may subsequently be directed to another basin for further MBBR processing or alternative treatment methods.

Inside the basin, there are media or carriers, which are small plastic chips designed to mimic the density of water, enabling them to disperse throughout the fluid. The aeration grid, located at the bottom of the basin, consists of a fan that promotes the effective movement of the media. This continuous motion ensures that the carriers engage with the waste present in the tank, facilitating its decomposition and enhancing oxygen levels within the vessel.

The sieve is another crucial element in the MBBR Sewage Treatment Plant. Its mesh-like design permits water to pass through while preventing the plastic carriers from escaping the basin.

The specific types of microorganisms introduced into the water are contingent upon the nature of the waste that the plant is tasked with treating.
