Moving Bed Biofilm Reactor(MBBR) Biological Filler Bio Carrier For Domestic And Industrial Sewage Treatment-25×12

ARTICLE

Moving bed biofilm reactor (MBBR) is a type of wastewater treatment process that was first invented by Professor Hallvard Ødegaard at the Norwegian University of Science and Technology in the late 1980s. The process takes place in an aeration tank with activated sludge and uses floating, recycled plastic carriers that a biofilm can grow on. The compact size and cheap wastewater treatment costs offer many advantages for the system. The main objective of using MBBR is water reuse and nutrient removal or recovery. In theory, wastewater will be no longer considered waste, it can be considered a resource.

OVERVIEW

Moving bed biofilm technology was developed as a solution to early issues encountered with biofilm reactors, such as hydraulic instability and uneven biofilm distribution. The MBBR system comprises an aeration tank, similar to an activated sludge tank, equipped with special plastic carriers that provide a surface for biofilm growth. Various types of plastic carriers are utilized, each offering distinct advantages and disadvantages in terms of surface area and shape.

The surface area of the carriers plays a crucial role in biofilm formation. The presence of free-floating carriers allows biofilms to develop on their surfaces, necessitating a large internal surface area for optimal contact with water, air, bacteria, and nutrients. The carriers are mixed within the tank by the aeration system, facilitating effective contact between the influent wastewater substrate and the biomass on the carriers.

Currently, high-density polyethylene (HDPE) is the most preferred material for MBBR carriers due to its plasticity, density, and durability.

To enhance biomass concentration in bioreactors, hybrid MBBR systems have been implemented, where both suspended and attached biomass coexist, contributing to the biological processes.

This approach has significantly improved the efficiency and performance of biofilm-based wastewater treatment systems, addressing earlier challenges and providing a more reliable and effective solution for sewage treatment.

FEATURES

• Large specific surface area, more attached microorganisms

• No need bracket, easy to fluidize, save energy

• Fast and easily to hang membrane, high biological activity

• Strong impact resistance, long lifetime

• Excellent nitrogen and phosphorus removal effect

• Small footprint, simple and flexible operation management

• Good hydrophilicity, good treatment effect

• Relying on biofilm treatment reduces the remaining sludge

CURRENT USAGE

Today, MBBR technology is used for municipal sewage treatment, industrial wastewater treatment, and decentralized wastewater treatment. This technology has been used in many different industries, some of them being:

• Automotive industry
• Chemical industry
• Food and beverage
• Metal plating and finishing

The MBBR system is considered a biofilm or biological process, not a chemical or mechanical process. Other conventional biofilm processes for wastewater treatment are called trickling filters, rotating biological contactors (RBC), and biological aerated filters (BAF).

APPLICATION

ADVANTAGES

Biofilm processes in general require less space than activated sludge systems because the biomass is more concentrated, and the efficiency of the system is less dependent on the final sludge separation.MBBR systems do not need recycling of the sludge, which is the case with activated sludge systems.

The MBBR system is often installed as a retrofit of existing activated sludge tanks to increase the capacity of the existing system. The degree of filling of carriers can be adapted to the specific situation and the desired capacity. Thus an existing treatment plant can increase its capacity without increasing the footprint by constructing new tanks.

 
Some other advantages are:

• Increased performance and volumetric treatment capacity

• Higher effective sludge retention time (SRT) which is favorable for nitrification

• Responds to load fluctuations without operator intervention

• Lower sludge production

• Less area required

• Resilient to toxic shock

• Process performance independent of secondary clarifier (due to the fact that there is no sludge return line).
