Product Overview

The LINZHEN Industrial Wastewater Treatment System is a complete, factory-engineered wastewater treatment solution independently developed by the LINZHEN environmental manufacturing facility in Shandong Province, China. Designed to handle the demanding conditions of modern manufacturing operations, this integrated system delivers a stable treatment capacity of up to 10,000 liters per hour and combines multiple proven treatment processes — Dissolved Air Flotation (DAF), Moving Bed Biofilm Reactor (MBBR), Membrane Bioreactor (MBR), Sequencing Batch Reactor (SBR), and AO (Anoxic-Oxic) biological treatment — into a single, transportable plant.

Unlike conventional standalone wastewater treatment equipment, the LINZHEN system supports both PLC fully automatic operation and manual control, effectively reducing daily labor and management costs for manufacturing facilities. With a service life extending over decades, the system is suitable for both industrial wastewater treatment and domestic sewage treatment, consistently producing effluent that meets discharge standards or can be reused as reclaimed water. It helps manufacturers comply with local environmental discharge regulations while reducing overall wastewater treatment costs.

How Does an Industrial Wastewater Treatment System Work?

A complete Industrial Wastewater Treatment System is carefully engineered by our experienced engineers to remove contaminants from wastewater, enabling the treated water to meet discharge standards or be reused in industrial processes. The specific treatment process is customized according to the characteristics of the wastewater and the required effluent quality.

The process typically begins with the pre-treatment stage, where coarse screening equipment removes large debris, suspended solids, and other materials that could damage downstream equipment. The wastewater then flows into an equalization tank, where fluctuations in flow rate and pollutant concentration are balanced to ensure stable system performance.

Depending on the specific application, technologies such as Dissolved Air Flotation (DAF) or sedimentation are incorporated to remove oil, grease, suspended solids, and other floatable or settleable contaminants. The wastewater then enters the biological treatment stage, where advanced technologies including MBBR, MBR, SBR, or AO biological treatment utilize beneficial microorganisms to decompose organic matter, reduce COD and BOD, and efficiently remove ammonia nitrogen.

After biological treatment, the water undergoes a solid-liquid separation process, followed by disinfection to eliminate harmful microorganisms. When higher water quality is required for water reuse, we customize the system by integrating advanced filtration or Reverse Osmosis (RO) technology. Finally, excess sludge is collected and dewatered, reducing sludge volume and lowering overall operating costs.

Key Advantages of Our Industrial Wastewater Treatment System

1. Customized for Different Industrial Wastewater

Every industry produces wastewater with different characteristics. Our engineers customize the treatment process based on your wastewater composition, treatment capacity, and discharge requirements to achieve the best treatment performance.

2. Multiple Proven Treatment Technologies

The system integrates advanced technologies such as DAF, MBBR, MBR, SBR, and AO biological treatment, allowing efficient removal of COD, BOD, suspended solids, oil, grease, ammonia nitrogen, and other industrial pollutants.

3. Stable Effluent Quality

A well-designed treatment process ensures consistent operation and reliable effluent quality, helping manufacturers comply with local environmental discharge standards or water reuse requirements.

4. Intelligent PLC Automation

The PLC control system supports both fully automatic and manual operation, enabling real-time monitoring, automatic alarms, and simplified system management while reducing labor costs.

5. Lower Operating Costs

Energy-efficient equipment, optimized process design, and intelligent control reduce electricity consumption, chemical usage, maintenance requirements, and long-term operating expenses.

6. Modular and Expandable Design

The system can be designed as a modular solution, making it easy to expand treatment capacity as production increases without replacing the entire wastewater treatment plant.

7. Durable Construction for Harsh Industrial Environments

Manufactured with high-quality carbon steel or stainless steel, the equipment offers excellent corrosion resistance, structural strength, and a long service life under demanding industrial operating conditions.

8. Turnkey Engineering and Technical Support

LINZHEN provides complete turnkey services, including process design, equipment manufacturing, factory testing, installation guidance, commissioning, operator training, and long-term technical support to ensure reliable system performance throughout its lifecycle.

Equipment Construction & Internal Components

The container shell is sandblasted to create a uniform rough surface, then finished with a triple-layer anti-corrosion coating — zinc-rich primer, intermediate epoxy, and top coat — ensuring strong adhesion, excellent rust resistance, and prevention of peeling. The system is rated for a water pressure grade of MAP10.

The integrated plant comes with a separate operation room for monitoring and management, featuring one-touch start/stop operation that ensures easy operation, enhanced safety, and reliable performance in a compact, mobile design. The standard basic configuration consists of seven units: Primary Sedimentation Tank, Anoxic Tank, Contact Oxidation Tank, Secondary Sedimentation Tank, Disinfection Tank/Unit, Sludge Tank, and Blower Room.

Inside the system, you'll find a complete set of pre-installed components: anaerobic pool with combined anaerobic packing, aerobic pool with elastic bio-media, MBR pool with MBR tensile membrane, microporous aerator, stainless steel self-priming pump, corrosion-resistant backflow pump, low-noise rotary aeration fan, online monitoring with touch-screen intelligent control, anti-corrosion chemical barrel, artificial climbing ladder, maintain manhole covers, and security door for the equipment room.
