Pure water equipment can be used in the chemical, pharmaceutical and food industries. There will be a full set of pretreatment devices in the whole system, mainly for the preliminary treatment of raw water to meet the feed water requirements of the reverse osmosis mainframe. The reason why the rever

Raw water contains a certain concentration of suspended and dissolved substances. Suspended matter is mainly inorganic salts, colloids and biological particles such as micro-organisms and algae. Dissolved substances are mainly soluble and insoluble salts (e.g. carbonates, sulphates and silicates

When reverse osmosis membrane elements are used, the RO feed water should be dechlorinated in order to prevent the membrane from being oxidized. RO membranes have a degree of resistance to chlorine until a significant drop in desalination occurs, which is approximately 200-1000 hours of exposure to

Every reverse osmosis system is subject to contamination and requires cleaning. Since contamination usually occurs with more than one type of contaminant, the typical cleaning process usually includes two major steps, low pH cleaning and high pH cleaning, as required.Different contaminants should be

echnical points of using the new RO reverse osmosis membrane.1. Rinse the quartz sand and coconut shell activated carbon cleanly, and rinse the newly installed quartz sand and coconut shell activated carbon for a longer period of time.2. detect whether there is residual chlorine, if there is residua

Preparation for the installation of reverse osmosis membrane elements①Cleaning the pressure vessel: Before installing the reverse osmosis membrane element, the internal environment of the pressure vessel needs to be cleaned to prevent dirt or debris from being deposited on the outer surface of the m

What is reverse osmosis membrane heavy contaminationAs a means of deep filtration, reverse osmosis membrane elements will inevitably have colloids, microorganisms, impurity particles and insoluble salts precipitating on their surface, so reverse osmosis units used in a variety of fields will eventua

As the water supply network ages, drinking water is prone to deterioration in ageing and rusted pipes. The emergence of home RO reverse osmosis membrane makes this problem solved, so how to choose a high-quality home RO reverse osmosis membrane? 1. AppearanceWhen choosing a home RO membrane you shou

What is a reverse osmosis membraneReverse osmosis membranes are the core component to achieve reverse osmosis and are artificial semi-permeable membranes with certain characteristics made to simulate biological semi-permeable membranes.It is generally made of polymeric materials. For example, cellul

Reverse Osmosis Membrane Technology and PrinciplesIntroduction.Membrane separation technology refers to the technology of selective separation of a mixture of molecules of different particle sizes at the molecular level when passing through a semi-permeable membrane, also known as a separation membr
