White or black suspended particles appear in pure water Solution: This is because the pipeline is contaminated, resulting in the growth of bacteria. This situation should be dissolved caustic soda into the precision filter, operate the regulating valve to close the waste water, pure water open to a Read More

Does the reverse osmosis equipment have good effect in removing fluoride?If people use super fluoride water, it will cause harm to the human body. In order to avoid people suffering from fluoride in their lives, reverse osmosis equipment can be used to remove fluoride. Most of the fluoride ions in g Read More

How should the reverse osmosis equipment be operated for the first time?The air in the pipeline will be driven away by low pressure and low flow, only when the air in the pipeline does not exist can the equipment operate normally. First of all, the pressure should be kept between 0.2~0.4MPa. When us Read More

Why do the seals in reverse osmosis equipment swell?Water 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 resistance sys Read More

How do I know which cleaning method to use to clean my membrane system?In order to get the best cleaning results, it is important to choose the right cleaning agent and cleaning procedure, as incorrect cleaning can actually deteriorate the system performance.Why is the pH of the RO produced water lo 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

1、How often should the reverse osmosis system be cleaned?In general, when the standardized flux decreases by 10-15%, or the system desalination rate decreases by 10-15%, or the operating pressure and differential pressure between segments increases by 10-15%, the RO system should be cleaned.Cleaning Read More

The microstructure and filtration mechanism of reverse osmosis (RO) membranes, the most efficient filter membranes for contaminant retention, has been a hot topic of research. So, is an RO membrane a porous or non-porous membrane? The knowledge and answer to this question will have a direct impact on the understanding of the filtration mechanism of RO membranes. The answer to this question is changing with the advancement of technology and the deeper analysis of the microstructure of RO membranes. 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

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

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.
