HEDP Chemical Application in Reverse Osmosis and Membrane Protection

 Reverse osmosis (RO) and ultrafiltration (UF) systems are prone to membrane fouling and scaling, which reduce water production efficiency and shorten membrane service life. HEDP chemical is an ideal scale inhibitor and membrane protective agent for such systems, with unique advantages in membrane compatibility and scale control.

Different from oxidizing scale inhibitors, HEDP is a non-oxidizing additive that will not damage the membrane structure or affect membrane performance. It can effectively inhibit the formation of inorganic scales on the membrane surface, especially calcium carbonate and calcium sulfate scales, which are the main causes of membrane fouling. HEDP has good solubility and can be evenly distributed in the water system, forming a protective layer on the membrane surface to prevent scale adhesion.
In addition, HEDP has strong chlorine tolerance and chemical stability, and can be used together with membrane cleaning agents without producing harmful by-products. It is suitable for various membrane systems such as seawater desalination, brackish water treatment and pure water preparation, effectively reducing the frequency of membrane cleaning and extending the service life of membrane elements.
Shandong Kairui Chemistry Co., Ltd provides high-purity HEDP specially designed for membrane systems, with strict quality control and complete certification (COA, MSDS). We also provide professional application guidance to help customers optimize dosing schemes and maximize the efficiency of membrane systems.

what does hedp mean

  HEDP , or 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid , is an important organophosphonic acid compound. The following is its brief introduction: Properties : HEDP is usually a colorless to light yellow transparent liquid, which can be miscible with water in any proportion, and raains stable under high pH value, not easy to be hydrolyzed, and not easy to be destroyed by acid and alkali.   Mechanism of action : It can form stable chelate with metal ions, and prevent metal ions from forming insoluble salt precipitation through chelation, so as to play the role of scale inhibition; at the same time, HEDP can form a layer of protective film on the metal surface to inhibit the corrosion of the metal to achieve corrosion inhibition effect. Application : HEDP is widely used in industrial field, it is an excellent water treatment agent, commonly used in boiler water treatment, circulating cooling water systa, etc. It can effectively prevent scale generation and me...

How to use Sticky Sludge Stripper

 A Sludge Stripper is a chemical specifically designed to remove slime, biofilm and algae from industrial circulating water systems. Below are some key points and recommendations when using a Sludge Stripper: 1. Dosing rate: - As a slime stripper: the recommended dosage is usually 100-200 milligrams per liter (mg/L) based on the amount of water retained in the system. - As an algaecide: the recommended dosage is 50-100 mg/L. 2. 2. Special case treatment: - If there are more algae in the system, in order to get faster killing and stripping effect, the dosage of KR-409 can be increased appropriately. 3. Fouling removal: - After the use of KR-409, if the circulating water appears to be fouled due to the stripping effect, these floating materials should be removed in time to prevent them from being redeposited in the system. 4. Avoid mixing: - Mud strippers should not be mixed with anionic surfactants such as polyacrylic acid (PAA) or hydroxypropylmethylacrylate (HPMA). - Similarly, sl...
