The Best Way to Use Corrosion and Scale Inhibitor 2020

People who use reverse osmosis water treatment equipment know that water treatment chemicals are called scale inhibitors. It has a good dispersion effect. Scale inhibitors can break down poorly soluble inorganic salts in water and interfere with or prevent impurities' precipitation and scaling on the membrane surface. So, do you know how to use scale inhibitors?

How to use scale inhibitors, we need to grasp three points—the dosing point, dosage, and dispensing method of scale inhibitors.

 

1. Dosing point: To achieve maximum efficiency, a scale inhibitor is best added before static mixing or filtration. The actual reading of the dosing pump should be calibrated before dosing. Adding should be done continuously and proportional to the inlet water flow. This will maintain the recommended dosing amount.

 

2. Dosing amount. The dosing standard solution required per unit volume of dosing is the dosing concentration of the dosing standard solution.

 

3. Preparation instructions of pharmaceuticals: scale inhibitor can be added directly, or the drug can be added after dilution in any proportion (diluted with RO water or ionized water). The standard solution's dilution should not be less than 10% (w/w). The diluted solution should be well stirred to ensure even mixing.

 

How to improve the stability of corrosion inhibitor and scale inhibitor?

 

Corrosion inhibitors and scale inhibitors are chemical reagents. All chemical reagents have chemical properties. Chemical properties refer to the chemical elements in that reagent. How active are these chemical elements? With which factors do they react easily? What kind of products will be produced after the reaction?

 

To prevent the reagent's chemical reaction, it is necessary to make the reagent more stable and give full play to its effect. Corrosion inhibitors and scale inhibitors are widely used in industry and need to stabilize their chemical properties. There are three ways to improve stability.

 

1, the scale inhibitor dispersion medium's viscosity has a certain impact on the stability of corrosion and scale inhibitors.

Generally speaking, the greater the dispersion medium's viscosity, the higher the stability of the water treatment corrosion inhibitor. This is because the dispersion medium's viscosity is large; the Brownian motion of liquid beads is strongly impeded. Slowed down the collision between the liquid beads to maintain the stability of the system.

 

2. A load of liquid beads greatly influences the stability of water treatment anti-corrosion inhibitors.

Stable water treatment anti-corrosion and scale inhibitor, liquid beads are generally charged. As the emulsion droplet liquid with the same charge, mutual repulsion, not easy to gather, stability increased.

The more corrosion and scale inhibitor ions adsorbed by the liquid beads, the greater the charge, the stronger the ability to prevent the liquid beads from coalescing.

 

3, in some cases, the addition of solid powder in the washing plant equipment can also stabilize corrosion and scale inhibitors.

Solid powder in water, oil, or the interface depends on the oil or water's wettability to the solid powder. Water treatment corrosion and scale inhibitor need certain stability to achieve corrosion and scale inhibition. Therefore, when using corrosion and scale inhibitors, stability must be enhanced.

 

vcycletech recommends that customers should also understand the details of corrosion, and scale inhibitors should be noted in the process of use.
