Factory Wastewater Treatment System Maintenance Services – A Key to Efficiency and Environmental Compliance

As environmental regulations become increasingly stringent, investing in a wastewater treatment system is mandatory for factories and industrial zones. However, to ensure stable and efficient operation that meets discharge standards, factory wastewater treatment system maintenance services have become an essential requirement.
 

 

So, what does wastewater treatment system maintenance include? Why is regular maintenance necessary? And how do you choose the right service to ensure efficiency and cost-effectiveness? Let’s explore these topics with Việt Water.

1. Why is Regular Maintenance of Wastewater Treatment Systems Necessary?

Industrial wastewater treatment systems are complex setups comprising mechanical equipment, electrical systems, biological processes, and various treatment technologies. During operation, these systems are exposed to wastewater with different chemical, biological, and physical characteristics.

 

Without regular maintenance and cleaning, the system is prone to:

• Pipe and tank blockages

• Decreased treatment performance (e.g., BOD, COD, TSS exceeding standards)

• Malfunctioning of pumps, blowers, and sensors

• Imbalanced microorganisms, leading to substandard effluent

These issues can cause production interruptions and potentially lead to fines or suspension of operations due to violations of environmental regulations.

2.1. Common Maintenance Tasks

A professional maintenance process typically includes:

• Tank cleaning: Equalization tanks, settling tanks, and aeration tanks must be regularly desludged and cleared of debris.

• Mechanical equipment maintenance: Inspection and servicing of pumps, blowers, mixers—lubrication, seal replacement, and filter cleaning.

• Electrical & control system calibration: Checking control panels, sensors, relays, and SCADA systems (if any).

• Biological system inspection: Measuring SV30, DO, pH, and microorganism density.

• Effluent water quality testing: Comparing with national discharge standards and recommending adjustments.
