1. Problems existing in the application of reverse osmosis equipment Compared with other desalination devices, such as evaporator, electrodialysis and double bed, reverse osmosis desalination has unique characteristics and advantages, and the localization of reverse osmosis has been paid more and m...

Technical points of using new RO reverse osmosis membrane: 1. First, wash the quartz sand and coconut shell activated carbon, and wash the newly installed quartz sand and coconut shell activated carbon for a long time. 2. Check whether there is residual chlorine. If the residual chlorine exceeds t...

Reasonable selection of water treatment equipment is the knowledge that every designer needs to master. As the core equipment of transportation and lifting, pumps are everywhere in water treatment projects. Therefore, how to select the pump is also very important! Usually, when selecting the type of...

We all know that the filtration accuracy of RO membrane is 0.1nm (i.e. 0.0001) μ m) It can filter out bacteria, heavy metals and plasma in water. Then the problem comes. Benzene molecules can be killed at about 0.5nm and Ca + ions can be killed at about 0.3nm. We can fully understand it. But w...

If the vertical multistage centrifugal pump is installed carelessly, it will lead to the failure of installation, which will affect the working performance of the pump in the future. Next, we will analyze the common installation errors and relevant solutions of vertical multistage centrifugal pump. ...

When the pressure transmitter is installed on site, there are many phenomena that the relevant pressure and differential pressure transmitters reflect incorrect process parameters: there are problems of blockage of impulse pipe, non-standard installation of throttling device, condensate tank and imp...

Pump is a necessary and common equipment in water treatment engineering. This knowledge and experience is very important. This article is a collection of 148 technical questions and answers about pump compiled by an engineer who has worked for 19 years. Dry goods are practical! 1. What is a pump? ...

1. Desalination rate and salt permeability of reverse osmosis membrane Salt transmittance = produced water concentration / influent concentration × 100% Desalination rate = (1 – salt content of produced water / salt content of influent) × 100% Salt penetration rate = 100% &ndash...
