China Membrane
Bioreactor market is predicted to proliferate during the forecast period
2024-2028. The market for Membrane Bioreactors in China is primarily being
driven by the growing need for water treatment solutions across the country.
This can be attributed to the declining freshwater resources and the increased
demand from residential sector for chemical-free, pure drinking water. The
market for membrane bioreactors in China is expanding as a result of rising
environmental concerns regarding efficient sanitation and wastewater disposal. Nowadays, MBRs are being used for wastewater
treatment in an increasing number of residential, commercial, and industrial
buildings. These systems are portable, lightweight, and economical, in terms of
both cost and energy use, and capable of aerating liquid to create tangential
liquid flow over membranes. Additionally, the market is expanding because more
companies, such as companies in the chemical, pharmaceutical, power, food and
beverage, and textile sectors, are using ecologically friendly water and
wastewater management techniques. The membrane bioreactor market in China is
likely to expand between 2024 and 2028 as a result of other factors, such as
rapid industrialization and the implementation of government regulations that
encourage the use of MBRs in place of the country's present wastewater
treatment facilities. Additionally, China intends to actively promote the reuse of
wastewater for household, industrial, ecological, and agricultural use.
Currently, China is aiming to increase the water reuse rates by more than
25% by 2025.
Membrane bioreactors (MBRs) are used for the
treatment of industrial and municipal wastewater. A suspended growth bioreactor
(UF) is connected with a perm-selective or semi-permeable membrane technology,
such as microfiltration (MF) or ultrafiltration (UF). The two most popular
membrane types for MBR systems are vacuum or gravity-driven and pressure-driven
systems. They keep the floating particles in place while separating the
sediments from the sludge concentration. They have enhanced effluent quality,
reduced carbon impact, and controlled biomass retention, and are effective
against diseases including cryptosporidium and giardia when compared to
conventional approaches.
The state-of-the-art MBR technology can control a
wide range of water pollutants, including nitrogen, bacteria, suspended
particles, pathogens, and other contaminants found in municipal and industrial
waste. The moving bed biofilm reactor and traditionally activated sludge
processes (ASP) are inadequate compared to MBR, for the treatment of
wastewater. Reverse osmosis, microfiltration (MF), ultrafiltration (UF), and
nanofiltration (NF) all employ MBR Membranes. Several polymeric materials,
including polyvinylidene fluoride (PVDF), polyethylene (PE), polyethersulfone (PES),
and others (RO), are used in the MBR technology. Compared to conventional
systems, MBRs produce less sludge because they have smaller reactor diameters
and greater sludge concentrations. In MBR, longer solid retention times (SRT)
also provide improved biological treatment.
In China, for the past 20 years, membrane
bioreactors (MBR) have attracted a lot of interest for the treatment and reuse
of wastewater. In recent years, China's average annual growth rate has been
close to 100%, compared to the global MBR market's average annual growth rate
of 10.9%. More than 300 MBR plants have been put into use, successfully, for a
variety of wastewater treatment processes, including municipal wastewater,
bathing wastewater, restaurant wastewater, landfill leachate, hospital
wastewater, petrochemical wastewater, and high-concentration industrial
wastewater. These plants range in capacity from 10 to 100,000 m3/d, with over
12 MBR plants having capacities more than 10,000 m3/d. Origin Water Technology
Co., Ltd. built Beijing's largest MBR plant, the Beijing Kunyu River WWPT,
which can treat and reuse 100,000 m3/d of municipal wastewater. With a 30,000
m3/d capacity, Motimo Membrane Inc. constructed the largest MBR facility for
the treatment of industrial wastewater in Tianjin. Petrochemical wastewater
treatment is the main industrial use for MBRs, and there are currently more
than 10 MBR facilities with a combined capacity of more than 5000 m3/d. The
built-in MBRs in South-East China are mostly utilized for the high-strength
industrial wastewater treatment, whereas MBRs in North China are mainly used
for the treatment and reuse of municipal wastewater.
