Exclusively designed for Mongolian clients engaged in wastewater treatment engineering, this high-efficiency material handling system consists of an enclosed bulk bag discharger and screw conveyor—engineered to deliver a dust-free, high-speed, and multi-point feeding solution that ensures timely supply of large-volume raw materials (e.g., coagulants, flocculants, activated carbon) to on-site wastewater treatment equipment, while addressing environmental and operational pain points.
A core requirement of Mongolian wastewater treatment projects is the timely supply of large quantities of raw materials—a need this system fulfills through its high-speed unloading capability. The enclosed bulk bag discharger is equipped with an automated bag-cutting and material discharge mechanism, paired with a high-torque drive system that enables a fast unloading rate of up to 15bags/hr (adjustable based on raw material density). This eliminates delays caused by slow manual bag handling, ensuring a continuous feed of essential treatment chemicals to on-site equipment (such as flocculation tanks, sedimentation basins) even during peak wastewater processing periods. Unlike open-type dischargers, its fully enclosed steel housing—with a precision-sealed bag interface and dust-tight access doors—prevents dust dispersion entirely, solving the long-standing issue of dust pollution in traditional manual unloading. This not only complies with Mongolia’s environmental protection regulations (aligned with regional air quality standards for industrial facilities) but also safeguards the health of on-site operators, who no longer face exposure to harmful chemical dust.
Another standout feature is the system’s multi-point feeding design, which allows one set of equipment to serve multiple on-site wastewater treatment units—a cost-effective solution for large-scale treatment plants. The screw conveyors are configured with modular, branchable pipelines and electrically controlled diversion valves, enabling flexible distribution of raw materials to 2–4 target equipment points (e.g., two parallel flocculation tanks and one activated carbon dosing unit). The PLC control system automatically adjusts the diversion valves based on real-time material demand signals from each equipment, ensuring precise, on-demand feeding without cross-contamination between different raw material types. This design reduces the need for multiple independent handling systems, cutting initial investment costs by 30–40% and simplifying overall system management.
Operation and reliability are optimized for Mongolia’s unique working conditions. The enclosed bulk bag discharger features a heavy-duty bag lifting frame (compatible with standard 1-ton bulk bags widely used in Mongolia) and an easy-to-operate touchscreen HMI (with Mongolian-English bilingual options), allowing operators to complete bag loading, unloading, and feeding adjustments with minimal training. To withstand Mongolia’s harsh climate—including extreme cold (down to -40℃) and dry, dusty conditions—all system components are built with cold-resistant materials (e.g., low-temperature-resistant steel for the discharger housing, frost-proof seals for conveyor pipelines) and IP66-rated electrical enclosures. The screw conveyors are also fitted with anti-blocking sensors and self-cleaning blades, preventing material buildup caused by low temperatures and ensuring uninterrupted operation even in challenging environments.
In addition to environmental and operational benefits, the system supports Mongolia’s wastewater treatment goals of efficiency and sustainability. The fully enclosed design minimizes raw material waste (reducing material loss to less than 0.5%), while the screw conveyors’ variable-frequency drives adjust power consumption based on feeding demand—lowering energy use by 15–20% compared to fixed-speed systems. This aligns with Mongolia’s efforts to promote energy-efficient and eco-friendly industrial practices in wastewater management.
This enclosed bulk bag unloading and conveying system not only solves the key challenges of Mongolian wastewater treatment projects—timely large-volume feeding, dust pollution control, and cost-effective multi-point supply—but also provides a durable, low-maintenance solution tailored to the region’s climate and operational needs. It is an ideal investment for Mongolian wastewater treatment facilities seeking to enhance process efficiency, comply with environmental standards, and reduce long-term operational costs.
