Choosing the Right Equipment is Your First Step to Success

With the rapid development of the glass deep processing industry, a large amount of industrial wastewater with high-density suspended solids and high turbidity is generated during production processes such as glass cutting, edging, coating, and cleaning. This type of wastewater has a complex composition and is extremely difficult to treat.

Challenges in Traditional Glass Wastewater Treatment

Currently, the mainstream basic process for glass wastewater treatment in the industry is defluoridation + coagulation sedimentation + advanced filtration + reuse. However, traditional water treatment equipment has exposed many insurmountable defects in practical applications, becoming a bottleneck restricting the green and low-carbon development of the industry.

Issues with Traditional Equipment

• Poor Adaptability: Traditional equipment struggles to manage high-density and concentrated suspended solids in glass wastewater, with inclined tube sedimentation tanks often collapsing, which reduces sedimentation efficiency and causes drastic fluctuations in effluent quality.

• High Operating Costs: Traditional water treatment processes require a large amount of water purification chemicals, leading to high energy consumption. In addition, the low water recovery rate causes serious waste of water resources.

• Space and Maintenance Issues: Traditional equipment requires large-scale infrastructure, incurs high civil engineering costs, and relies on manual cleaning, which increases the workload of maintenance personnel and operation costs.

Problems with Zero Discharge Requirements

Traditional equipment also struggles to meet the core needs of the glass deep processing industry for high efficiency, environmental protection, and cost reduction, especially with regard to zero discharge requirements.

Dinghui Environmental Protection's Solutions

As a top supplier in the field of glass deep processing wastewater reuse equipment, Hangzhou Dinghui Environmental Protection Technology Co., Ltd. has developed a series of high-performance water treatment equipment that subverts traditional models. Their innovations are designed to address long-standing industry pain points such as low efficiency, high cost, and difficulty in meeting environmental standards.

Core Technological Breakthroughs

Dinghui Environmental Protection has achieved a leap from "adaptability improvement" to "subversive breakthrough" in core treatment technologies.

SS Double Selection Integrated Machine

• Flagship Product: Dinghui's third-generation glass wastewater treatment equipment, which combines flotation and sedimentation in a two-way separation process. This process allows for precise removal of suspended solids with different characteristics in a single equipment.

• Pressure Flotation Principle: Easily floatable suspended solids are fully integrated with microbubbles to form microbubble clusters that float upward, while high-particle-size, high-density suspended solids are treated through sedimentation.

SS Double-Layer Mixed Flow Sedimentation Integrated Equipment

• Design Innovation: This equipment uses thickened wear-resistant inclined plates to avoid the collapse of traditional inclined tubes. It integrates the advantages of inclined tube and vertical flow sedimentation tanks, improving sedimentation efficiency and equipment stability.

• Self-Cleaning Function: Features an intelligent mud hopper system for automatic cleaning, and can optionally include a self-cleaning quartz sand filtration layer.

Advanced Treatment: Submerged Ultrafiltration + Process Equipment

• Dual Treatment Mode: Solid-liquid separation + ion adsorption. This equipment can efficiently adsorb ionic pollutants, such as organic solvents and heavy metal ions, overcoming the limitations of traditional ultrafiltration methods.

• Low Energy Consumption: The system operates at an energy-efficient rate, consuming only 0.03-0.06 kWh/m³.

Wastewater Recycling and Water Conservation Solutions

Pure Water Cleaning Online Recovery Equipment

• Compact and Efficient: Designed to help businesses save over 65% of pure water consumption by recovering overflow wastewater from the cleaning process. The system purifies wastewater to a high standard, replacing newly produced pure water for reuse.

• Savings and Environmental Impact: This solution reduces wastewater discharge, achieving a closed-loop recycling system that saves water and supports environmental protection.

System Integration Design

Dinghui Environmental Protection’s system integration optimizes the entire treatment process:

• No Large-Scale Tanks: The system doesn’t require large wastewater adjustment tanks, instead using an intelligent flow control system to adapt to varying wastewater discharge characteristics.

• Continuous Treatment: The system can continuously adjust operational parameters based on influent water quality and quantity to ensure stable effluent quality.

• Zero Discharge Goal: The system achieves relative zero discharge of glass wastewater, perfectly complying with national "double carbon" strategies and environmental policies.
