Tap water is now an essential source of water in our lives, but do you know when your tap water is the dirtiest and most toxic? For everyone's health, these time periods must be kept in mind! First, use water for the first time in the morning Because the quality of some faucets is not up to th...

With the promotion of urbanization rate and industrialization rate, the requirement of improving the quality and efficiency of sewage and the market of comprehensive water environment treatment, the market space of sewage treatment will still be expanded. It is estimated that more than 100 billion y...

Reverse osmosis, also known as reverse osmosis, is a kind of membrane separation operation with pressure difference as driving force to separate solvent from solution. Because it is opposite to the direction of natural infiltration, it is called reverse osmosis. Failure caused by poor quality of in...

Introduction to soft water salt Chinese Name: soft water salt Main ingredients: sodium chloride (NaCl) with purity above 99.1% Also known as: ion exchange resin regeneration agent Working principle of water softener There are many kinds of water treatment methods, and the water treatment tech...

There are many misunderstandings about membrane in many people at present, In particular, these easy misunderstandings are explained here (dry goods, every point is truth) one point one Misunderstanding 1: membrane water treatment equipment is a high difficulty operating system The automatic contr...

During the operation of industrial circulating cooling water system, the circulating water is continuously concentrated due to the evaporation of water and loss of wind blowing. The salt content in the system exceeds the standard, the increase of anion and anion ions and the obvious change of pH val...

Precision filter, also known as security filter, is generally set in front of the pressure vessel to remove fine particles with turbidity more than 1 degree, so as to meet the requirements of the subsequent process for water inflow; Sometimes it is also set at the end of the whole water treatment sy...

Analysis of pollution (1) Calcium carbonate scale: Calcium carbonate scale is a kind of mineral scaling. When the scale inhibitor / dispersant adding system fails, or the acid pH regulating system fails and the pH of the feed water increases, calcium carbonate scale may deposit. It is very necessa...
