Reverse osmosis membrane element is a word that often appears in life, in the eyes of many people is one of the main components of purification equipment, but really understand the membrane element and can have a few, many important terms in the membrane element are not very well understood, then the next is to introduce the basics of how to calculate the membrane flux of the membrane element.
Membrane flux means the rate at which a membrane element can pass through raw water, and is the amount of reverse osmosis membrane fluid on the membrane area within a certain period of time. It is also the amount of water that is filtered through a reverse osmosis membrane in a given period of time.
Reverse osmosis membrane flux is generally measured in hours and is the number of litres of fluid per square metre per hour.
The formula for calculating the membrane flux of a reverse osmosis membrane: J= V/(T×A)
J - membrane flux (L/m2-h); V - sampling volume (L); T - sampling time (h); A - effective membrane area (m2);
Membrane flux is a standard that can effectively calculate the number of reverse osmosis membrane elements used in a piece of equipment, which can be calculated by dividing the hourly water production and the flux of the membrane elements, and it should be noted that in the case of different temperatures and different raw water quality, the calculation will have more or less deviations, so we need to do a good test when calculating by professionals.
