The renovation of the wastewater treatment system
Date public: 13-06-2024||View: 1935
Upgrading wastewater treatment systems is a crucial step to enhance performance and meet increasingly stringent environmental standards. This process not only addresses the shortcomings of old systems but also incorporates advanced technologies that save energy and operational costs. In this article, Đại Nam Environmental Solutions explores cases where upgrades are necessary and how to achieve optimal results.
1. Why Upgrade Wastewater Treatment Systems?
After operating for a long period, wastewater treatment systems can deteriorate or fail to meet treatment standards. At this point, businesses need to either upgrade their systems or increase the capacity of their treatment facilities. This issue becomes increasingly important due to the consequences it causes and the lack of a comprehensive solution.
Moreover, outdated technology or systems, built a long time ago, may no longer align with current trends. This can lead to high operational costs and frequent maintenance. Implementing upgrade solutions using modern technology offers the best results with optimal costs.
**Reasons for Upgrading Wastewater Treatment Systems**
2. Cases Requiring Upgrading of Wastewater Treatment Systems
-
The microorganisms in the biological tank have died and need to be re-cultivated.
-
The treated wastewater does not meet the receiving water quality standards.
-
The old system and equipment are damaged, affecting treatment efficiency.
-
The actual capacity exceeds the designed capacity.
-
High operational costs.
3. Causes of Ineffective Wastewater Treatment Systems
-
Microorganisms die due to increased wastewater flow, leading to higher pollutant concentrations.
-
A severe shortage of microorganisms in the aeration tank, resulting in low sludge concentration.
-
Sludge is black, has a foul odor, and is difficult to settle.
-
Nitrogen treatment does not occur due to a lack of anoxic environment (anoxic tank).
-
High levels of suspended solids in the effluent from the biological sedimentation tank, with small, underdeveloped floc particles causing colored wastewater.
-
Maintenance and upkeep of equipment are not performed regularly, leading to rust and malfunctioning equipment, which negatively impacts treatment efficiency.
Indicators for When to Upgrade a Wastewater Treatment System
3.1 Upgrading Wastewater Treatment Systems with MBBR Technology
Upgrading to MBBR (Moving Bed Biofilm Reactor) technology enhances the effectiveness of wastewater treatment system upgrades. This ensures that treated water meets QCVN standards and can be reused for purposes such as irrigation, toilet flushing, cooling factory roofs, or street cleaning. MBBR systems operate stably despite fluctuations in wastewater composition and reduce energy and maintenance costs. The system simplifies operation by eliminating the need for sludge recycling, F/M ratio control, BOD ratio, and suspended solids monitoring in influent water after system operation.
3.2 Upgrading Wastewater Treatment Systems with MBR Technology
MBR (Membrane Bioreactor) technology uses PES membranes reinforced with ABS frames, providing durability and stability under chemical and physical impacts. The membrane pore size is uniformly 0.2 µm, offering high water permeability and minimizing membrane clogging. The MBR module consists of multiple membrane sheets designed for specific capacities and types of wastewater. MBR membranes filter out suspended solids and solids in municipal wastewater, ensuring that the treated water meets discharge standards and can be reused.
