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

Characteristics of membrane process technology for electroplating wastewater treatmentAs most industrial plating wastewater is complex and may contain toxic elements, it can cause great damage if discharged into the natural environment. Electroplating wastewater usually contains a high concentration Read More

The earth's surface is 71% ocean and 29% land, but there are also rivers, lakes and other waters on land, and glaciers and other solid water, to say the earth's water is still a lot, statistics show that the earth's water resources up to 1.386 billion cubic kilometres, but we also know that most of Read More

Ceramic membrane separation technology is one of the very advanced membrane separation technologies in the international arena in recent years and is widely used in chemical, food, pharmaceutical and environmental protection industries. Ceramic membrane is a new material of inorganic membrane, which Read More

3. Microfiltration and ultrafiltration membrane technologyBasic PrinciplesBoth ultrafiltration and microfiltration are liquid phase separation processes driven by differential hydrostatic pressure, and there is no fundamental difference in principle. Under a certain pressure, when a mixed solution c Read More

1. Forward Osmosis (FO) technologyThe principle of forward osmosis (FO)The solvent is separated from the solution by a semi-permeable membrane that can only pass through the solvent but not the solute molecules. The solvent molecules will spontaneously pass through the membrane from the solvent side Read More

What is a split membrane bioreactor?Separate membrane bioreactors use the membrane module as a separate unit from the bioreactor, the mixture is pressurised by the system into the membrane module, the permeate of the membrane module is the effluent of the system and the concentrate of the membrane m Read More

Water Treatment ApplicationsDrinking water treatmentWith the development of the economy and society, the water environment has become more polluted, the water quality has deteriorated, and there are more and more pollutants in the water, especially organic pollutants. The traditional drinking water Read More

Ultrafiltration is used in water treatment and other industrial purification, concentration and separation processes, either as a pre-treatment for the process or as a deeper treatment for the process. In widely used water treatment processes, it is often used as a means of deep purification. Accord Read More

The principle of ultrafiltration water treatment is a membrane separation and filtration technique using a certain pressure difference as the driving force, UF ultrafiltration membrane modules are mostly made of polymeric materials. Most suitable for the separation and thickening of solutes in solut Read More

Ultrafiltration (UF) technology is a membrane separation technology between microfiltration and nanofiltration, with an average pore size of 3~100 nm, and has the function of purification, separation and concentration of solutions. Its retention mechanism mainly consists of membrane sieving and elec Read More

PTFE (Polytetrafluoroethylene, trade name "Teflon", commonly known as "King of Plastics") was discovered in 1932 by Dr. Roy Plunkett, who came to the United States after graduating from DuPont to work on organic fluorine. In the summer of 1938, he discovered the white powder polymer polytetrafluoroe Read More

Membrane separation technology is a technology that uses the selectivity of the membrane (pore size) and the energy difference between the two sides of the membrane as the driving force to achieve separation due to the different mobility of the components in the solution through the membrane. As the Read More

1.Deep drinking water purificationNF membrane was first used in the drinking water treatment industry, mainly for water softening, NF membrane for divalent and multivalent ion retention rate can reach more than 90%, for monovalent salt retention rate of 10% ~ 90%, the characteristics of NF membrane Read More

NF membranes originated in the 1970s with the development of thin-layer composite RO membranes and in 1978, Cadotte et al. prepared the first thin-layer composite polyamide NF membrane using piperazine (PIP) and 1,3,5-homophthaloyl chloride (TMC). It has been widely used in water and wastewater trea Read More
