Partners in Co-creation

As environmental regulations continue to tighten and operational efficiency and sustainability become higher priorities, wastewater treatment systems are no longer simply discharge management tools — they are a critical factor affecting cost, capacity, and operational stability. High-strength wastewater with elevated sludge concentrations in particular puts system design capability and long-term operational stability to the test.

LCY provides a comprehensive MBR wastewater treatment solution that combines equipment technology, customized design, and operator training to help clients address high-strength wastewater treatment challenges. Through biological system optimization, automated maintenance mechanisms, and flexible equipment design, LCY improves treatment efficiency while reducing labor demands and operating costs — enabling a more stable and sustainable operational model.

Challenges Under High Sludge Concentrations: Balancing Operating Costs and Treatment Performance

High-strength wastewater treatment has long been a central challenge for the environmental services industry, and elevated mixed liquor suspended solids (MLSS) concentrations in particular tend to undermine system stability. When sludge concentration becomes too high, it can impair aeration efficiency and biological treatment capacity, while increasing the frequency of equipment fouling, maintenance interventions, and associated labor costs.

In this case, the client had been operating an ultrafiltration (UF) system for wastewater treatment, but sludge concentrations in the system reached 20,000 ppm — far exceeding the typical operating load of approximately 12,000 ppm for conventional membrane filtration equipment. Sustained high sludge concentrations led to frequent equipment disassembly and cleaning, increased labor burdens, and steadily rising operating costs.

In addition, policy changes in response to African swine fever (ASF) expanded the volume of wastewater requiring treatment. With costs and treatment demands rising in parallel, achieving both treatment effectiveness and operational efficiency became an urgent priority for the client.

Biological System Optimization Combined with Custom Equipment to Improve Overall Treatment Efficiency

Faced with system instability caused by high sludge concentrations, LCY did not default to simply scaling up equipment. Instead, the team first addressed the biological treatment process itself — systematically adjusting test parameters and operating conditions to establish a more efficient biological treatment regime.

The technical team improved biomass activity and adjusted the food-to-microorganism (F/M) ratio, resulting in improved performance across the existing biological system. Sludge concentration was reduced from over 20,000 ppm to below 8,000 ppm while maintaining effective pollutant removal capacity.

In addition, LCY's equipment can be configured to suit site-specific conditions, including adjustments to dimensions, operating mode, and system layout. Combined with multiple rounds of operator training and on-site technical support, the client progressively built a more complete operating workflow and stronger in-house management capability.

LCY MBR System: An Integrated Solution Combining Customization, Automation, and Operational Support

The LCY MBR system offers a high degree of customization, enabling equipment design to be tailored to the specific characteristics of different industries and site conditions — including equipment dimensions, system configuration, and operating protocols — to deliver solutions that more accurately match real-world requirements.

This project deployed a leased containerized MBR system with maintenance service, which reduced installation constraints and minimized the time required for equipment upgrades. The system also incorporates an automated maintenance cycle running once per week, substantially reducing the labor requirements and maintenance costs associated with frequent manual disassembly and cleaning.

Beyond equipment supply, LCY provides comprehensive operator training and technical services to help clients master optimal system operation, ensuring that equipment performance remains stable over the long term and that service life is effectively extended.

Reduced Operating Costs with Improved Operational Stability

After implementing LCY's solution, the client successfully resolved the system instability caused by high sludge concentrations. The leased containerized MBR system with maintenance service and automated maintenance design reduced equipment disassembly frequency and reduced both personnel workload and overall maintenance costs.

Compared to a traditional equipment-only supply model, LCY's approach — combining customized system planning, operator training, and ongoing technical support — helps clients build complete operational capability, allowing the equipment to deliver stable, sustained performance over time.
