Ways to treat high pH water effectively and simply: 1. **Chemical Treatment**: Adding chemicals such as citric acid, vinegar, or sulfuric acid can help lower the pH level of water. However, it is important to use these chemicals carefully and follow prop

What are the harmful effects of high pH water?

High pH water can be harmful to health if it exceeds the permissible level. For example, water with a pH level above 8.5 can affect human taste, causing discomfort and dry throat.

In addition, high pH water can also affect some aquatic animals, such as fish and other aquatic organisms. However, if the water pH is within the normal range (from 7 to 8.5), it is not harmful to human health and aquatic life.

How to treat high pH water

Using chemicals

Using chemicals is a fast and effective method to treat high pH water. You simply need to add a certain amount of chemicals that can lower the pH level appropriately. Specifically:

pH- chemical: This is commonly used in treating pool water. This material helps to safely reduce the pH level. The formula for calculating the amount of pH- chemical for pool water is as follows: 1kg for 100m3 of water, pH decreases by 0.1 unit.

HCL 32% chemical: This is a liquid chemical, strong acid, and has a relatively pungent smell. HCL 32% can effectively and cost-efficiently adjust the pH level in water. However, the safety of this method is not high. When applying, proper personal protective equipment and usage techniques are required. The formula for calculating HCL 32% chemical in treating high pH water is to use 1 - 4 liters of chemical for 100m3 of water.

In addition to the above two chemicals, there are other methods to treat high pH water such as using sulfuric acid (H2SO4), nitric acid (HNO3)...

Neutralization method

This method is commonly used in treating wastewater.

• The mechanism is to mix wastewater containing high acid with wastewater containing high alkali to neutralize the environment.
• When applying, additional chemical agents need to be added to the tank to balance and reduce shock.
• Filter acidic water through neutralizing filter materials.

Note: Using the neutralization method can increase the amount of calcium in the water, making it become hard water. Therefore, it is necessary to install a pre-filter and regularly check and clean to reduce the risk of clogging.

Using alkaline ion water filter

Alkaline ion water filter is an extremely effective method to treat high pH water.

This device not only completely removes contaminants in water such as bacteria, impurities, chemicals, toxic substances, and water color. It also uses water electrolysis technology to produce water with various pH levels.

The water that comes out of the alkaline ion water filter can be consumed directly, used for cooking, washing face, cleaning utensils... Depending on the pH of the water, there are different applications.

Precipitation method

This method aims to remove phosphorus and heavy metal ions in water through the precipitation process. The chemicals obtained are OH-, CO2-...

The precipitation method is most commonly applied in industrial wastewater treatment.

Consultation with experts

In general, the methods for treating high pH water that we have introduced above provide quite good results. However, to choose the appropriate solution, it is necessary to consider the following factors:

• Water source characteristics.
• Purpose of using water after treatment.
• Water flow rate.

Therefore, specific advice from environmental experts is extremely important and necessary. Therefore, the best method is to contact experts for direct support.
