Last Updated on July 24, 2022 by Kevin Chen

MBR, also known as Membrane Bio-Reactor, is a new type of water treatment technology that combines a membrane separation unit with a biological treatment unit. The MBR Package plant is mainly composed of two parts: bioreactor and MBR membrane module. In addition, there are also components such as the tank, aeration system, pump, pipeline and spear parts like valves.

Working Principle

MBR Package Plant uses MBR membrane separation technology to retain the activated sludge and macromolecular organic matter in the biochemical reaction tank, no need for a secondary sedimentation tank. Therefore, the activated sludge concentration is greatly improved, the hydraulic retention time (HRT) and sludge retention time (SRT) can be controlled separately, and the refractory substances are continuously reacted and degraded in the reactor.

MBR Package Plant parameters

The core component of the SPERTA MBR package plant is the membrane bioreactor, which is mainly aimed at small and medium-sized sewage treatment projects with a daily sewage discharge of less than 2,000m3/d.

MBR package plant can flexibly configure the process flow according to the raw water quality, so that the equipment has a wide range of applicability, and can treat domestic sewage, hospital sewage treatment, industrial wastewater, etc. to meet the discharge standards.

MBR package plant mainly includes the following five units
(1) Regulating tank (2) Biological Tank (3) MBR Tank(4) Clearwater tank (5) Equipment room:

Regulating tank
The regulating tank is mainly to adjust the quantity and quality of sewage. The general volume recommendation is 35%-40% of the daily processing capacity. It is recommended that customers build the regulating tank(steel-concrete structure) by themselves, and can also be included in the complete set of equipment.

Biological Tank (Anaerobic Tank)

As a pre-treatment unit, the anoxic tank mainly plays the following roles: 

  1. It provides a place for denitrification, and the nitrate-nitrogen produced by the nitrification process is fully converted into nitrogen gas.
  2.  It is the decomposition of macromolecular organic matter into small molecules under the action of hydrolase. Improving sewage biodegradability.

Aerobic Tank(MBR Tank)
In the aerobic tank (DO, 2-4mg/L), Ammonia Nitrogen (NH3-N) in the water undergoes a nitrification reaction to generate nitrate, and at the same time, the organic matter in the water is oxidized and decomposed to supply phosphorus-absorbing microorganisms with energy, and the microorganisms absorb phosphorus from the water. Phosphorus enters cell tissues, is enriched in microorganisms, and is discharged from the system in the form of phosphorus-rich sludge after precipitation and separation.

Equipment room
The equipment room is the place where the electromechanical equipment is placed. The equipment room is equipped with blower, suction pump, PLC control cabinet, and UV disinfection equipment.

Advantages Of The MBR Package Plant

Advantage 1: The MBR package plant can be fully automated. Compared with the traditional process, the management difficulty and management risks are significantly reduced, and the stable operation of the equipment is ensured.

Advantage 2: The quality of the effluent is excellent and can be directly reused.

Advantage 3: Small footprint and save civil construction investment. The MBR treatment process can save 20%-30% of the floor space.

Advantage 4: The discharge of excess sludge is greatly reduced. The sludge is trapped in the tank by the MBR membrane, and there is sufficient time for the reaction. The organic matter that constitutes the sludge can be fully degraded into carbon dioxide and water, so the excess sludge output is extremely low.

Advantage 5: The UV disinfection process – safe and efficient. The turbidity of the effluent from the MBR process is almost zero, and UV disinfection can be used to ensure that the bacteriological indicators of the sewage meet the discharge requirements, and at the same time save the cost of purchasing disinfectants.

Advantage 6: The equipment is made of high-quality materials, with long service life and a continuous running time of up to 70,000 hours. SPERTA provides lifetime maintenance services.

What is Hydraulic Retention Time HRT

What is Hydraulic Retention Time (HRT) and How is it Calculated?

Hydraulic Retention Time (HRT) is a term used in water treatment processes, referring to the average time that wastewater remains in a reactor, essentially the average reaction time between the wastewater and the microorganisms in the biological reactor.

What is a good MLSS value

What is a Good MLSS Value?

MLSS measures the solid concentration in wastewater treatment tanks. For regular systems, the ideal range is 2,000 to 5,000 mg/L. In advanced processes like MBR, it’s higher, around 8,000 to 12,000 mg/L. Staying in these ranges ensures effective treatment and clean output.

How to transport the MBR Membrane

How to Transport the MBR Membrane?

When we purchase the MBR membrane, it is usually transported by large trucks. We must understand some matters in advance in the transportation process, especially long-distance transit, to avoid damage to the MBR membrane element caused by the wrong operation.
