Containerized sewage treatment unit

A Containerized Sewage Treatment Unit (CSTU) is an integrated wastewater treatment system encapsulated in standard shipping containers, combining modular design, mobility, and high treatment efficiency. It integrates sewage collection, pretreatment, main treatment, advanced purification, and discharge/reuse modules into a compact container body, eliminating the need for complex on-site civil engineering and enabling rapid deployment near sewage sources.
Core Features

CSTU is distinguished by itscontainer-based integration, plug-and-play operation, and strong mobility. Built on standard 20ft or 40ft shipping containers, it is compatible with global transportation modes (truck, ship, train) and can be quickly transferred between different projects. Its modular internal structure allows flexible combination according to wastewater volume and quality requirements.

Key Advantages

• Rapid Deployment: The prefabricated design enables on-site commissioning within 1-7 days after delivery, significantly shortening the project cycle compared with traditional on-site built systems (which take months).
• Space-Saving: The integrated container structure requires minimal floor space, suitable for scenarios with limited area such as construction camps, remote industrial parks, and urban fringe areas.
• Stable Treatment Performance: Equipped with mature processes (e.g., MBR, AO, SBR), it efficiently removes COD, BOD, ammonia nitrogen, and suspended solids. Effluent can meet local discharge standards or be reused for irrigation, cleaning, and other purposes.
• Low Operational Difficulty: Adopts PLC automatic control system, supporting remote monitoring of water quality, equipment status, and automatic alarm, reducing the demand for on-site professional operators.
• Strong Adaptability: Resistant to fluctuations in inlet water volume and quality, and can operate normally under harsh environmental conditions (temperature range: -20℃ to 45℃).

Typical Application Scenarios

Emergency sewage treatment (post-disaster, sudden pollution), construction sites, mining areas, oil fields, remote villages, tourist resorts, temporary exhibition venues, and small and medium-sized enterprises with mobile wastewater discharge needs.

Application Value

CSTU provides a “fast, flexible, and reliable” wastewater treatment solution, effectively solving the problems of decentralized sewage discharge and emergency treatment. It not only helps users comply with environmental regulations but also reduces initial investment and operation costs, and supports the recycling of water resources, conforming to the concept of green and sustainable development.
