What is the reason why well water turns yellow?

Well water is no longer common in cities nowadays, but it is still used in some rural areas. But some well water will be yellow. There are many reasons why well water turns yellow. For example, silt in the water can turn well water yellow. Summer rainstorms and flash floods can also turn well water yellow, or there are a lot of suspended matter in the well water. Then the depth of the well also matters.

Because there are relatively more iron and manganese metal ions in the strata, the content of iron and manganese ions in the water is also relatively high. Usually, these iron and manganese ions exist in the form of divalent ions. After being extracted, they combine with oxygen in the air to become trivalent or tetravalent ions and turn yellow. Most of the yellowing of well water is caused by excessive iron and manganese ions. So how to deal with the yellowing of well water? What should we do if the well water turns yellow?

First, let's analyze the characteristics of excessive iron and manganese

Characteristics of excessive iron ions in well water:

1. The water pumped from the well is crystal clear, but after a few hours or a day it turns light yellow, and the depth of the color depends on the iron ion content;

2. After a few days of storage, yellow solids appeared at the bottom of the water and the container walls were stained yellow;

3. After boiling such water, the water will also turn slightly yellow, and the depth of the color depends on the iron ion content;

4. There may be an oil film floating on the water surface;

5. When you first pump the well water up, it may smell irony.

Characteristics of excessive manganese ions in well water:

The dyeing ability of manganese ions is relatively weak. If the iron ions in the water exceed the standard, the dyeing effect of manganese ions will usually not be seen. If only the manganese ions exceed the standard, the container may be dyed black and there will be delamination. If washing clothes, the color of the clothes will become darker.

We already know the reason why the well water turns yellow, and the next step is to deal with it. We can add an appropriate amount of edible grade alum, stir it thoroughly, leave it for thirty minutes or an hour, and then filter the formed flocs. However, this method is inconvenient to use and is not a long-term solution. To this end, Guangzhou Chenxing Environmental Protection Technology Co., Ltd. (abbreviated as: Chenxing Environmental Protection) is a water treatment manufacturer specializing in solving the problem of yellow well water, yellow well water filters, etc., and provided us with solutions. At the same time, Chenxing Environmental Protection

We also specialize in the research and development and production of water treatment equipment such as reclaimed water reuse equipment, groundwater treatment equipment, and softened water treatment equipment.

Yellowing well water treatment process:

1. Pump well water into the aeration device;

2. The aeration device uses oxygen from the air to mix with well water containing iron and manganese ions;

3. The aerated well water passes through the iron and manganese removal filter;

4. The well water that has passed through the iron and manganese removal filter then passes through the quartz sand filter, activated carbon filter, precision filter, etc.;
