Technical Spotlight: Unlocking the Efficiency of the Lanjiang LJJYJ Integrated Automatic Dosing Device

In water treatment processes, the preparation and dosing of flocculants—typically organic macromolecular substances—present significant operational challenges. Because of their high viscosity, these chemicals are prone to clumping during dissolution, which severely complicates the process, increases manual labor, and limits automation.

To address these pain points directly, Nanjing Lanjiang developed the LJJYJ Integrated Flocculant Preparation Series. As a technician evaluating equipment upgrades, here are the most compelling features of this system that make it an exceptional choice for modern water treatment facilities:

1. Seamless Automation & Integration

• All-in-One Process: The device seamlessly integrates the dissolving, maturing, and dosing of chemicals into a single, fully automatic system.

• Unattended Operation: Featuring a sophisticated automatic control system with sensors (like level and material meters), the unit supports true unattended operation. It automatically starts, stops, and alarms based on system demands, guaranteeing continuous and safe chemical preparation.

2. Smart Anti-Clogging & Precision Feeding

• Moisture-Proof Tubing: One of the most attractive operational features is the heating tape installed on the feeding tube. This keeps the dry powder from absorbing moisture, effectively eliminating the risk of clumping and blockages.

• Variable Frequency Control: The dry powder feeding motor speed is regulated by a variable frequency drive. This allows technicians to precisely control the dosing volume and the final concentration of the chemical solution, ensuring accuracy while significantly reducing chemical waste.

3. Optimized Compartmentalized Structure

• Strategic Staging: Constructed from durable Stainless Steel or PVC, the tank is typically divided into three separate compartments: the preparation compartment, the maturation compartment, and the dosing compartment (note: the 500L model features two compartments).

• Anti-Settling Design: Each compartment is equipped with an electric agitator to ensure thorough mixing. Brilliantly, to prevent the matured solution from precipitating, the agitator in the dosing compartment is programmed to perform intermittent mixing even when the system pauses the preparation cycle.

4. Compact Footprint & Versatility

• Space & Durability: Despite its advanced capabilities, the integrated device boasts a small footprint, simple installation, and a long service life. The control box and agitator feature a robust IP54/IP55 safety rating, protecting vital components in harsh environments.

• Broad Application: It is highly adaptable and widely used across various sectors, including municipal water supply treatment, wastewater treatment, and power industry water applications
