Solid neutralization balls for water treatment—An innovative environmental strategy for regulating the pH value of acidic wastewater from air preheaters.
Air preheaters, as essential components in industrial systems, often generate acidic wastewater, which not only poses potential harm to the environment but also violates environmental emission standards. The pH value of industrial wastewater discharge, especially for acidic wastewater, must be adjusted to near neutral to meet stringent environmental requirements. Although traditional liquid neutralizing agents are commonly used, they are inconvenient to operate, prone to human error, and may cause secondary pollution. The emergence of solid neutralization balls for water treatment provides an elegant and efficient solution to this challenge.
Technical Overview
Solid neutralization balls for water treatment are made from various inorganic alkaline materials through a special process.
They continuously release alkaline substances, which react with the acidic components in wastewater, thus neutralizing the
acidic wastewater. These spherical solid neutralizing agents are characterized by easy placement, controllable dissolution
rate, and stable neutralization effect. They not only have high neutralization efficiency but also have low corrosiveness to
equipment, ensuring the stable operation of the wastewater system over the long term.
Operating Principle
The operating principle of solid neutralization balls for water treatment is straightforward. In the acidic wastewater
treatment system generated by air preheaters, these solid neutralization balls are placed in appropriate locations.
When wastewater passes through, the alkaline substances within the balls gradually release and react with the acidic
components in the wastewater to neutralize them. The neutral salts produced by the reaction are further diluted and
discharged with the wastewater, stabilizing the pH value of the wastewater within the regulatory range.
Advantages and Characteristics
1. Ease of Operation: The method of using solid neutralization balls is straightforward. Simply place them into the wastewater without the need for complex equipment or procedures.
2. Reduction of Secondary Pollution: The slow dissolution of alkaline substances in the solid neutralization balls helps to avoid the issue of secondary pollution caused by excessive addition of liquid neutralizing agents.
3. Cost-Effectiveness: The long-term pH adjustment capability reduces the need for manual monitoring and adjustment, thereby saving on operational costs.
4. Environmentally Friendly: This technology offers an environmentally friendly approach to wastewater treatment. Its use and neutralization by-products do not impose additional burdens on the environment.
Application Example
In a wastewater treatment project targeting the air preheater of an industrial plant, the introduction of a certain amount of solid neutralization balls resulted in a significant adjustment of the wastewater's pH value within a short period. The pH, which was initially around pH 4 due to acidity, stabilized to near neutral, meeting the emission standards required by regulations. Additionally, the slow-release properties of the solid neutralization balls ensured pH stability, avoiding pH fluctuations that may occur due to emergency addition of neutralizing agents.
With increasingly stringent environmental requirements, the efficiency of industrial wastewater treatment and its environmental impact have become crucial indicators for evaluating a company's social responsibility. The development of solid neutralization ball technology provides a practical and environmentally friendly solution, ensuring that acidic wastewater generated by key equipment such as air preheaters is effectively neutralized to meet regulatory emission standards. This paves the way for industrial enterprises to create a green manufacturing environment, opening up new avenues for sustainable practices.
