1 What are the pretreatment equipment you know? A: Pretreatment equipment includes: mechanical filter, high-efficiency fiber filter, activated carbon filter, precision filter, ultrafiltration, microfiltration, sodium ion softener, iron and manganese removal filter, dosing device, raw water tank, ae...

The pore size of RO reverse osmosis membrane is as small as nanometer (1 nanometer=10 * - 9 meters). Under certain pressure, water molecules can pass through the RO membrane, while inorganic salts, heavy metal ions, organics, colloids, bacteria, viruses and other impurities in the source water canno...

The reverse osmosis scale inhibitor is generally added to the security filter of the reverse osmosis system, that is, before the precision filter. It is added to the dosing device and added to the pipeline of the reverse osmosis equipment through the metering pump. The reverse osmosis scale inhibito...

The internal and external surface anti-corrosion and coating of chemical water treatment system equipment, pipes, valves and accessories can meet the requirements of corresponding media and surrounding environmental conditions. The reverse osmosis device is controlled by PLC, including the normal o...

Pure water refers to purified water, which is generally sourced from urban tap water. Through multi-layer filtration, it can remove harmful substances such as microorganisms, but also remove minerals such as fluorine, potassium, calcium, magnesium and other minerals needed by human body. 1、 Ozone s...

Failure Analysis of Reverse Osmosis Water Purifier Unable to Start The placement requirements of the reverse osmosis water purifier are relatively high, so the environmental requirements are relatively high. First of all, select hundreds of common desktop reverse osmosis water purifiers, which can ...

The reverse osmosis system includes three parts: raw water pretreatment, reverse osmosis device and post-treatment. RO system has its specific requirements for raw water pretreatment. Due to the wide variety of raw water and its very complex composition, according to the requirements of the raw wate...

What is the difference between pure water, purified water and ultrapure water? 1. The difficulty of manufacturing is different. At present, the pure water used in the market is basically prepared by reverse osmosis, distillation and other methods. Purified water is pharmaceutical water prepared by...

Comparison of nanofiltration membrane, reverse osmosis membrane and ultrafiltration membrane Nanofiltration membrane: capable of intercepting substances of nanometer scale (0.001 μ m). The operating range of nanofiltration membrane is between ultrafiltration and reverse osmosis. Its molecular we...

In view of the many misunderstandings that many people have about the membrane at present, these misunderstandings are particularly explained here (technical dry goods, every point is the truth) 1.1 misunderstanding 1: membrane water treatment equipment is a highly difficult operating system The a...

Let's first understand what is softened water In daily life, we often see that the inner wall of the kettle will generate scale after long use. What is the reason? It turns out that the water we take contains many inorganic salts, such as calcium and magnesium salts. These salts cannot be found...

Algae removal process route 1. Air flotation The air flotation method for algae removal is to supply dissolved air water by the dissolved air system, adhere the algae in the water through the bubbles in the water, make them float on the pool surface, and scrape them with a slag scraper. Air flotat...
