Waste water treatment solution

Wastewater Grinder – Efficient Solids Reduction for Reliable Pumping
Liantai Wastewater Grinder is designed to cut and shred bulky, fibrous and solid debris in wastewater into smaller particles, helping prevent pump clogging, pipe blockages and sewer backups.
By reducing solids directly in the wastewater flow, the grinder can protect downstream pumps and equipment, reduce maintenance requirements, and improve the reliability of wastewater systems.
5 Types for Different Wastewater Applications
Liantai offers 5 types of wastewater grinders to meet different flow rates and operating conditions:
Type Recommended Flow Rate Typical Applications
Non-drum Grinder < 340 m³/h Pumping stations, wastewater treatment systems
Single-drum Grinder 400–1,000 m³/h Medium-flow wastewater applications
Double-drum Grinder > 1,100 m³/h High-flow pumping stations and large wastewater systems
Pipe-type Grinder < 300 m³/h Pipelines, buildings, small pumping stations
Sludge Cutter Grinder < 300 m³/h High-solids and poor-flowability applications, such as oil and chemical pipelines
