Empowering High-Tech Glass Manufacturing: Compact and Efficient Water Treatment System Achieves Near-Zero Discharge and 95% Reuse Rate of High-Silicon Wastewater

With the rapid development of high-tech industries such as electronic information, new energy, and aerospace, the demand and requirements for upstream materials—such as ultra-thin electronic glass, photovoltaic glass, high-strength cover glass, etc.—are increasing day by day. During the precision processing of these cutting-edge glass products, such as grinding, cutting, and polishing, a large amount of Industrial Wastewater containing extremely fine siliceous powder (glass powder) is generated. This type of wastewater is difficult to settle and has complex water quality. Traditional treatment methods not only occupy a large area but also struggle to meet the stringent requirements for efficient reuse, thus becoming a key bottleneck restricting green manufacturing and cost control.

In response to this industry pain point, Kintep New Power has launched an integrated skid-mounted water treatment system centered around the Lamellar Clarifier and High-Efficiency Automatic Filter Press. This solution is specifically designed to treat industrial wastewater with high difficulty and high Suspended Solids, enabling glass manufacturing enterprises to achieve efficient purification and resource reuse of wastewater with lower energy consumption and footprint. 

High-tech Glass Production and Water Treatment Challenges

On the production lines of products such as TFT-LCD glass substrates, semiconductor glass interposers, and flexible display cover plates, the requirements for processing precision and cleanliness have reached the extreme. This means that: 

1. Wastewater Characteristics : The glass powder particles contained in the wastewater are finer and harder, making traditional sedimentation methods inefficient and difficult to stably control the turbidity of the effluent. 
2. Space Pressure: High-tech manufacturing workshops usually have high cleanliness and compact space layouts, making it difficult for large water treatment facilities to integrate into the production line.
3. Resource Costs: The production process requires a large amount of high-purity cleaning water, resulting in significant water resource consumption. Meanwhile, sludge disposal also constitutes a significant operating cost.

Core Solution: Intensive Design with Synergy of Two Key Technologies

Our system, through a highly integrated skid-mounted design, condenses the entire water treatment workshop into a compact unit. 

• High-Efficiency Solid-Liquid Separation Unit: Lamellar Clarifier

Its internal dense inclined tube packing group sharply shortens the settling distance, achieving the efficient application of the "shallow pond theory". This system can quickly separate micron-sized glass powder from wastewater, ensuring clear and stable effluent, and providing reliable guarantee for subsequent reuse. Compared with traditional processes, its floor area can be reduced by more than 70%. 

• Sludge Reduction Unit: High-Efficiency Automatic Filter Press

The separated silicon-containing sludge is transported to our chamber filter press. Through high-pressure squeezing, the moisture content of the sludge can be significantly reduced, forming a hard and dry sludge cake. The volume of the sludge can be reduced by up to 90%, greatly reducing the cost and environmental impact of external transportation and disposal. 

Core value created for customers

• Significantly improve the reuse rate of reclaimed water : After being treated by this system, the effluent has clear water quality and can be directly reused in the grinding, cooling, cleaning and other processes of the production line, helping enterprises achieve a wastewater reuse rate of over 95%, significantly reducing the cost of fresh water intake. 
• Ultimate Space and Energy Savings: The skid-mounted design occupies minimal space and is suitable for rapid deployment in high-tech factories with limited space. The overall system has been optimized, with energy consumption reduced by 30%-50% compared to traditional systems.
• Promote Green and Sustainable Development : This system helps enterprises easily comply with strict environmental regulations, transforming wastewater from a "discharge burden" into a "recyclable resource", perfectly aligning with the high-tech industry's pursuit of ESG (Environmental, Social, and Governance). 

Application Examples

This solution has been successfully applied to multiple high-end glass manufacturing fields, including but not limited to: 

• Treatment of grinding and polishing wastewater from electronic display glass . 
• Cutting and edging wastewater generated during the production process of photovoltaic glass . 
• Silicon-containing wastewater generated from the processing of special industrial glass.
