Dissolved oxygen and free carbon dioxide in water are the main factors causing corrosion in feedwater systems. Boiler feedwater deaeration and carbon dioxide is the key to ensure the safe and economic operation of boilers. This paper introduces the principle and application of degassing membranes th Read More

The principle of ceramic membranesThe ceramic membrane separation process is a "staggered flow filtration" form of fluid separation process: the raw material liquid flows at high speed in the membrane tube, the clarified permeate containing small molecules is driven by pressure to pass outwards thro Read More

Porous membranesPorous ceramic membranes are available in three main configurations: flat, tubular and multi-channel, of which flat membranes are mainly used in small-scale industrial production and laboratory research. Tubular membranes are combined to form a form similar to a tube heat exchanger, Read More

The rapid development of the economy and society has gradually improved people's quality of life, but the lack of awareness of energy saving and environmental protection in daily life has led to a continuous increase in the amount of sewage in life. Coupled with the rapid development of the modern i Read More

Kubota, JapanKubota is one of the largest water treatment equipment manufacturers in Japan, founded in 1890 and headquartered in Osaka. The company's main water treatment equipment includes pumps, valves, grids, dewatering machines, various water supply and drainage pipes and membrane bioreactors (M Read More

MBR membranes are mainly used to treat wastewater and are currently used in a wide range of applications such as municipal wastewater treatment projects and large industrial wastewater treatment. The current MBR membrane market is very competitive, and the hot selling MBR membrane brands are Mennen, Read More

4. The selection points of the installation location of water softening equipmentWater softening equipment has good water quality and stable system operation, and is used by many enterprises. While installing water softening equipment, the following points should be noted.(1) Water softening equipme Read More

1. Reverse osmosis equipment in the seal ring expansion phenomenonWater treatment equipment in reverse osmosis equipment in order to achieve the membrane shell between the zones of sealing isolation, the membrane shell requires three types of sealing rubber ring. In order to reduce the installation Read More

Ceramic membranes, also known as inorganic ceramic membranes, are asymmetric membranes formed by a special process using inorganic ceramic materials. Ceramic membranes are divided into two types: tubular ceramic membranes and flat ceramic membranes. The tubular ceramic membrane is densely packed wit Read More

Ultrafiltration membranes are polymeric semi-permeable membranes used in the ultrafiltration process to separate polymeric colloids or suspended particles of a certain size from the solution. Driven by pressure, the membrane pore size is 1 to 100nm and is an asymmetric membrane type. The pore densit Read More

MBR has been widely and maturely used in wastewater treatment, because MBR replaces secondary sedimentation tank, can guarantee the effluent SS and high sludge concentration, save a lot of sewage division in the operation of some troubles, but, membrane pollution problems have also been plagued by t Read More

Climate change, population growth and urbanisation have raised concerns about water scarcity in many EU countries (particularly in the Mediterranean and Atlantic coastal regions), but a new regulation will ease these growing pressures and mark a move towards a circular economy.The European Parliamen Read More

Special softening functionsMembrane softening of water is achieved by using the selective permeability of nanofiltration membranes for different valence ions. In addition to hardness, membrane softening can also remove turbidity, colour and organic matter, and its water quality is significantly bett Read More

Population growth and water environment pollution have exacerbated the water crisis, seriously affecting the health and sustainable development of the economy and society, becoming one of the most important issues facing the 21st century. With the improvement of people's living standards, the qualit Read More

Membrane contamination usually refers to the process whereby substances in the mixture collect on the membrane surface (outside) and within the membrane pores (inside), causing the membrane pores to become blocked and contributing to a reduction in porosity, resulting in a reduction in membrane flux Read More
