MUCK・SLURRY TREATMENT

What Is Muck・Slurry Treatment?

Excavated soil generated in the Earth Pressure Balance (EPB) shield method becomes slurry-like in nature and must be treated as construction sludge. In recent years, due to a shortage of disposal sites and increasing environmental considerations, the importance of recycling and properly treating muck has grown significantly. TAC provides optimal solidifying agents and treatment materials tailored to soil conditions and construction requirements, enabling efficient and environmentally responsible Muck・Slurry Treatment.

Muck Solidification Materials

Selecting the appropriate solidifying agent is essential for treating slurry-like excavated soil, depending on soil conditions and intended use. TAC offers a wide range of materials—including polymer-based and inorganic types—to support resource recovery and improve transportation efficiency.

Materials for Turbid Water Treatment

Turbid water generated during tunneling and excavation work does not meet environmental standards in its untreated state and therefore cannot be discharged into rivers or sewer systems.
TAC provides the high-performance dewatering enhancer TG Scall, which achieves both improved treatment efficiency and reduced environmental impact. Optimal formulations can be designed according to site-specific water quality conditions and treatment processes.

TG Scall

TG Scall is a chlorine-free water treatment agent. With a single-component formula requiring only a small dosage, it delivers excellent dewatering performance. It offers outstanding economic efficiency, workability, and coagulation performance, representing a next-generation dewatering enhancer that balances environmental considerations achieved through dechlorination with improved on-site efficiency.
