Fundamentals of reverse osmosis (nanofiltration)

The phenomenon that pure water flows from the low-concentration brine side through the membrane to the higher-concentration brine side is called osmosis.

The principle and scope of application of nanofiltration membrane in water treatment

The pore size of the nanofiltration membrane is nanoscale, which can allow water to pass completely, while intercepting or partially intercepting substances with a larger molecular weight than water.

Nanofiltration Membrane + Reverse Osmosis Membrane Treatment of Nickel Plating Wastewater

The method of plating nickel on metal or some non-metal surfaces by electrolytic or chemical methods is called nickel plating. Nickel plating includes electroless nickel plating and electroless nickel plating. Electroless nickel plating uses metal nickel as the anode, the cathode as the plated part, and the direct current as the current. A uniform and dense nickel coating is deposited on it. Bright nickel is obtained from baths with brighteners, while dark nickels are obtained from electrolytes without brighteners.

Advantages of nanofiltration membranes

Nanofiltration is a relatively new membrane process that is commonly used with waters with low total dissolved solids (such as surface water and fresh groundwater) to soften (remove multivalent cations) and remove disinfection by-product precursors, Such as natural organic matter and synthetic organic matter.

Causes and Operation Analysis of Nanofiltration Membrane Pollution

Microorganisms include bacteria, algae, fungi and viruses. Adverse consequences: First, the mass reproduction and metabolism of microorganisms will produce a large amount of colloidal substances, which will cause the membrane to be blocked and cause a sharp decrease in the membrane flux; second, it will cause an increase in the total number of bacteria in the produced water. It is extremely unfavorable for the long-term operation of the entire device, so great attention should be paid to the microbial contamination of the nanofiltration membrane.

How does nanofiltration membrane technology decolorize xylose?

Xylose is a component of xylan derived from plant and animal heparin, chondroitin and glycoproteins. In some glycoproteins, it is the linking unit between the sugar chain and serine (or threonine). So far, no free xylose has been found in nature. Xylose can provide intercellular communication for glycoconjugates of receptors on cell membranes. Secondly, xylose has antibacterial and antifungal effects, especially against Gram-negative bacteria and Streptococcus albicans, and can help the growth of intestinal probiotics.
