The MBR membrane bioreactor is a new type of treatment process. Compared with the traditional process, it has the characteristics of a small footprint, good effluent quality, and low operating cost. It is one of the hotspots in wastewater treatment and has wide applications.What is the MBR Membrane Read More

Firstly: Do you want to know the principle and characteristics of reverse osmosis membrane? Reverse osmosis membrane can intercept material greater than 0.0001 micron, is one of the most fine membrane separation products, it can effectively intercept all dissolved salts and molecular weight of organ Read More

What is the relationship between influent TDS and conductivity?When a feed water conductivity value is obtained, it must be converted to a TDS value so that it can be entered in the software design. For most water sources, the conductivity/TDS ratio is between 1.2 and 1.7. For ROSA design, a ratio o 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

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

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

The project was put into operation in December 2017 and has been running for more than 3 years so far. Doing the daily maintenance work during the use of MBR membrane can ensure its normal and stable operation, prolong the service life of membrane modules and reduce the operating cost of membrane bi Read More

In system operation, membrane contamination is a very difficult problem, which causes a significant decrease in the removal rate and water permeability of the reverse osmosis unit and membrane flux, as well as increasing the operating pressure of each section and contributing to higher operating and operational costs, which seriously affects the service life of the membrane and the development and utilization of reverse osmosis technology. Read More

When the raw water is not flowing into the reverse osmosis membrane system, all remaining abnormal substances in the pre-treatment equipment that may accompany the flow of water should first be thoroughly removed before commissioning the equipment. Read More

Reverse osmosis equipment is easy to operate and its high efficiency saves money in various areas such as manpower. However, some problems inevitably occur in the daily operation of reverse osmosis equipment, so in order to extend the service life of reverse osmosis equipment, the operator should not only have certain maintenance skills, but also the daily data of reverse osmosis equipment is particularly important to record. Read More

With the widespread use of water purification equipment in the water treatment industry, reverse osmosis membranes are gradually gaining traction. The cost of reverse osmosis membranes is one of the main concerns of consumers. If done properly in the design, pre-treatment, daily maintenance and self-cleaning design of the reverse osmosis system, the service life of the reverse osmosis membrane can be extended and system operating costs greatly reduced. Good maintenance will help extend the life of the reverse osmosis membrane. Read More

In the process of using the equipment, in addition to the normal decay of performance, the decay of equipment performance due to pollution is more serious. The main types of contamination are chemical scale, organic and colloidal contamination, microbial contamination and so on. Different contaminants show different symptoms. The symptoms of membrane contamination also vary from one membrane company to another. Read More

With the development of the global economic level and the geometric growth of the population, modern industrial wastewater discharges, urban waste, rural pesticide spraying and so on have caused serious water pollution, so reverse osmosis technology is becoming more and more important and the application of reverse osmosis membranes is becoming more and more widespread. So do you know how many types of reverse osmosis membranes there are? Read More

Reverse osmosis plant is used with sufficient pressure to make the solvent in the solution (generally water) pass through the reverse osmosis membrane (or semi-permeable membrane) and separate out, because this process is opposite to the direction of natural osmosis, hence the name reverse osmosis. Reverse osmosis equipment engineering can adapt to all types of raw water with salt content, especially in water treatment projects with high salt content, and can obtain good technical and economic benefits. Reverse osmosis method of desalination rate increased, high recovery rate, stable operation, small footprint, easy operation, reverse osmosis equipment in addition to salt, but also most of the bacteria, colloids and large molecular weight of organic matter removal.
