China Glass Grinding and Polishing Processing Water Suppliers | Factory Solutions for Wastewater Management

Glass processing wastewater is primarily contaminated by coolant and saw blade cooling water. The main pollutants found in these types of wastewater include resin acids, unsaturated fatty acids, lignin, and their degradation products. In particular, resin acids, such as rosin acid and hippocampal acid, are significant contributors to the pollution. As a leading factory in China, we focus on providing efficient solutions for treating glass processing wastewater, ensuring that our suppliers can meet environmental regulations and maintain sustainability. Our expertise in managing these pollutant components makes us a reliable partner for businesses seeking to optimize their wastewater treatment processes.

Features

Wastewater classification

1. Saw blade cutting wastewater (sawing machine wastewater)

The main pollutants of glass processing wastewater are "coolant" and saw blade cooling water. Generally, the main components of coolant are resin acid and its saponification products, unsaturated fatty acids and their saponification products, lignin and its degradation products, etc. Resin acid is mainly rosin acid and hippocampal acid, etc.

2. Grinding wastewater and trimming machine wastewater

After the raw materials are processed, the surface of the board usually needs to be further processed, and there will be a lot of dust pollutants during the processing. In order to reduce pollution, water is usually used as an auxiliary dust removal agent.

Pretreatment Process Wastewater Characteristics

The water consumption of the glass deep processing industry is mainly in the pretreatment process, including edge grinding, drilling cooling water and washing water. The wastewater generated in the pretreatment process contains a large amount of glass silica powder and a small amount of silica powder, corundum grit, cutting kerosene, cleaning agent and citric acid. Therefore, the wastewater volume is large, the concentration of glass powder is high, and it is difficult to biodegrade. In addition, there are some additives and oils in the water, and the wastewater is generally acidic.

Frequently Asked Questions

What are the primary pollutants in saw blade cutting wastewater?

The main pollutants are coolants and saw blade cooling water. The coolant contains components such as resin acid (specifically rosin acid and hippocampal acid), unsaturated fatty acids, lignin, and their respective saponification or degradation products.

Why is water used during the grinding and trimming processes?

During grinding and trimming, the board surface undergoes processing which generates a large amount of dust pollutants. Water is used as an auxiliary dust removal agent to minimize this dust pollution.

Which processes consume the most water in glass deep processing?

Water consumption is primarily concentrated in the pretreatment stage, which includes edge grinding, drilling cooling water, and washing water processes.

What substances are found in glass pretreatment wastewater?

This wastewater contains a large amount of glass silica powder along with smaller amounts of silica powder, corundum grit, cutting kerosene, cleaning agents, citric acid, additives, and oils.

Why is glass processing wastewater difficult to biodegrade?

Biodegradation is difficult because the wastewater contains a high concentration of inorganic glass silica powder, has additives and oils present, and is generally acidic in nature.
