Why Choose LINZHEN?

Fast Deployment

All treatment equipment—including tanks, blowers, pumps, piping, electrical control panels, and automation systems—is pre-installed inside standard 20-foot or 40-foot shipping containers before leaving the factory. On-site work is limited to foundation preparation, utility connections, and system commissioning. As a result, installation time is reduced from several months to just a few weeks.

Flexible Modular Expansion

As future wastewater treatment demand grows, additional containerized treatment modules can be seamlessly integrated with the existing system. The modular design allows treatment capacity to be scaled up without major civil reconstruction—simply add more containers.

Lower Construction Costs

Minimal civil engineering requirements significantly reduce labor costs, construction complexity, and overall project risk. This makes the LINZHEN CWTP one of the most cost-effective wastewater treatment solutions available for both municipal and industrial applications.

Global Shipping Compatibility

Standard container dimensions mean the system can be transported worldwide using conventional shipping methods—by sea, rail, or road—reducing logistics costs while simplifying international delivery.

Factory-Tested Reliability

Every mechanical component, piping connection, electrical circuit, instrumentation device, and PLC automation control system is fully installed, integrated, and tested under simulated operating conditions before shipment. This ensures consistent manufacturing quality, minimizes on-site installation errors, and guarantees reliable long-term operation.

Full Automation

The system operates under intelligent PLC control with a touch-screen HMI interface. No manual intervention is required during normal operation—secure, stable, and truly autonomous.

Grade 1A Effluent Quality

Advanced biological treatment processes combined with precision disinfection deliver consistently stable effluent that meets Grade 1A discharge standards, removing COD, BOD, ammonia nitrogen (NH₃-N), suspended solids (SS), oil, grease, and phosphorus.

Treatment Technologies

Depending on wastewater characteristics and discharge requirements, the LINZHEN CWTP can incorporate one or more of the following proven treatment technologies:

• MBBR (Moving Bed Biofilm Reactor) — High-efficiency biofilm treatment using suspended plastic carrier media

• MBR (Membrane Bioreactor) — Combines biological treatment with membrane filtration for superior effluent quality

• AO / A²O (Anaerobic-Anoxic-Oxic) — Biological nutrient removal for nitrogen and phosphorus reduction

• SBR (Sequencing Batch Reactor) — Batch-process biological treatment in a single tank

• DAF (Dissolved Air Flotation) — Removes suspended solids, oils, and greases

• Lamella Clarifier — High-rate sedimentation using inclined plate technology

• Sand Filtration — Polishing filtration for residual suspended solids removal

• Activated Carbon Filtration — Adsorption of dissolved organics, color, and odor

• Reverse Osmosis (RO) — Advanced desalination for water reuse applications

• UV Sterilization — Chemical-free pathogen inactivation

• Chlorine Disinfection — Residual disinfection for distribution system protection

Working Principle

A typical LINZHEN containerized wastewater treatment system follows six essential treatment stages:

1. Preliminary Treatment Incoming wastewater passes through mechanical screening to remove large debris, fibers, plastics, and suspended solids that could damage downstream equipment.

2. Equalization Wastewater is collected in an equalization tank where flow rate and pollutant concentration are stabilized, ensuring consistent operating conditions for the biological process.

3. Biological Treatment Organic pollutants, ammonia nitrogen, and biodegradable contaminants are removed by microorganisms through aerobic and/or anaerobic biological processes. Technologies such as MBBR, MBR, AO, or SBR are selected based on project-specific requirements.

4. Solid-Liquid Separation Suspended solids are separated from treated water using sedimentation, membrane filtration, or dissolved air flotation, depending on wastewater characteristics and effluent targets.

5. Disinfection Ultraviolet sterilization or chemical (chlorine) disinfection eliminates harmful microorganisms before the treated water is discharged or reused.

6. Sludge Treatment Excess sludge generated during biological treatment is concentrated and dewatered using sludge dewatering equipment (such as a multi-plate screw press), reducing disposal costs and improving environmental compliance.

Basic Configuration

The standard LINZHEN CWTP is composed of seven integrated treatment units within a single containerized structure:

Construction Quality & Internal Components

The LINZHEN CWTP is built to withstand harsh operating environments. The container shell undergoes sandblasting followed by a triple-layer anti-corrosion coating system: zinc-rich primer, intermediate epoxy coating, and a durable topcoat. Internal components include:

• Combined anaerobic packing for high-surface-area biofilm growth

• Aerobic elastic packing in the contact oxidation tank

• Microporous aerators for efficient oxygen transfer

• Low-noise rotary aeration blowers

• Stainless steel self-priming sewage pumps

• Corrosion-resistant nitrification/denitrification backflow pumps

• PVC corrosion-resistant piping throughout

• MBR membrane modules with high-tensile fibers (designed for long service life)

• Disinfectant metering pump with anti-corrosion chemical storage tank

• Touch-screen intelligent control panel with online monitoring

• Maintenance manhole covers and security door for the equipment room

• Artificial climbing ladder for safe access
