This high-efficiency glass particle separator is designed for glass edging and CNC machining centers, and is ideal for treating and recycling cooling water from one edger or one CNC machine in glass processing plants. It converts glass edging wastewater into reusable process water, achieving suspended solids (SS) as low as 50 mg/L to support closed-loop cooling water systems and reduce fresh water consumption.
The system is widely used in glass edging lines, CNC machining centers, and other glass cold processing equipment where high-quality recycled water and low operating cost are critical.
Small and medium-sized glass manufacturers and processors in Europe and Russia
The system uses PLC and a touch screen interface for fully automatic operation, clearly displaying real-time running status and fault causes to simplify daily operation and maintenance.
Automatic backwash is triggered during shutdown to prevent internal clogging and maintain long-term stable performance of the wastewater treatment equipment.
Based on the water level in the clear water tank, the raw water pump flow rate is controlled by variable frequency; this allows automatic adjustment of chemical dosing, ensuring accurate and stable dosing under varying loads.
A low-level alarm is activated when the chemical tank is short of water, and the system can be configured to send SMS notifications via the mobile network to remind operators to refill chemicals in time.
Operating cost can be as low as 0.08 yuan per ton of treated water, making it suitable for glass factories aiming to lower long-term water treatment expenses.
Key internal components are made of PP or 304 stainless steel to minimize corrosion in corners and internal surfaces, greatly extending equipment lifespan; the external surfaces can be coated with anti-corrosion paint for additional protection.
For customers equipped with a pure water machine (RO system), concentrated water can be reused for chemical dosing, significantly reducing the discharge and waste of concentrated water.
Working with chemical manufacturers, the system uses a specially developed low-salt precipitant to replace traditional polyaluminum chloride, ensuring effective treatment while reducing corrosion of pipelines and equipment.
Ultrasonic level control replaces traditional float level switches, offering higher stability and a lower failure rate in industrial environments with glass particles and sludge.
This design helps maintain accurate water levels and reliable automatic control in glass edging wastewater treatment systems.
The fully automatic control system includes an automatic backwashing function during shutdown to prevent internal clogging of pipes and filters.
This reduces manual cleaning frequency and helps maintain long-term stable operation of the wastewater treatment equipment.
Internal swirl flow design allows the system to remove engine oil, snow oil, and other lubricants originating from machines and bearings in the glass processing line.
Improved removal of oil contaminants enhances water quality and protects downstream equipment.
Clean water quality is strictly controlled using high-precision pH detectors and salt detectors, ensuring that discharged or recycled water meets pH standards and has low salinity.
When the pH value exceeds the set standard, the system triggers an alarm, helping operators take corrective action and reducing corrosion during circulation.
Coordinated control of the raw water pump and dosing pump ensures that chemicals are dosed appropriately, using low-salt coagulants developed for glass edging wastewater.
This scientific dosing strategy maintains treatment efficiency and minimizes corrosion to tanks, pipes, and cold processing equipment.
The equipment occupies a small area thanks to a vertical-flow, high-speed precipitation design that offers large water output and continuous discharge.
This makes it suitable for glass factories with limited floor space but high demands for recycled cooling water.
The dosing box is custom-built with PP material, featuring a large dosing opening and a clean, modern appearance to replace traditional dosing tanks.
Full-automatic dosing reduces manual handling of chemicals and improves dosing accuracy.
The system strictly controls the ratio between water intake and chemical dosing to reduce overall treatment cost while maintaining effluent quality.
By lowering chemical consumption and reusing concentrated water from pure water machines, total cost of ownership is reduced for glass plants.
The equipment includes a bottom washing function to prevent powder and sludge deposition at the bottom of the tank.
This reduces the frequency and difficulty of tank cleaning and helps maintain stable treatment performance.
The pressure filter can be equipped with an automatic plate shifting mechanism and vibration function, combined with a lifting frame for the filter press.
This design significantly reduces manual labor for sludge handling and improves dewatering efficiency.
