Centralized wastewater treatment is a method widely implemented by many businesses, residential areas, and factories. Depending on various factors, people may opt for either centralized or decentralized treatment systems. To help you determine the most suitable option, let’s explore the topic with Môi trường Đại Nam.
1. Overview of Centralized and Decentralized Wastewater Treatment
Centralized wastewater treatment is a comprehensive system that includes various equipment to treat polluted wastewater. Once treated, the wastewater released into the environment is safe and can be reused depending on the company's needs.
In contrast, decentralized wastewater treatment is a standalone model designed for systems with smaller capacities. This method reduces construction and installation costs for businesses. Typically, these systems are used by households or small-scale production facilities with a capacity ranging from 200m³ to 1000m³ per day.
2. The Debate: Centralized or Decentralized Wastewater Treatment?
To determine whether a business should install a centralized or decentralized system, several factors need to be considered:
2.1 Decentralized Wastewater Treatment
Currently, authorities and managers often prefer decentralized systems due to their ability to handle domestic wastewater effectively, providing high environmental protection. Additionally, they help reduce costs for small-scale industrial plants. Decentralized systems are commonly found in many urban areas across various districts in Vietnam. This method is suitable for facilities that are not too large, operating at moderate capacity. The system typically includes septic tanks, SBR tanks, or AO tanks. The collected wastewater is pumped to the treatment facility, with traditional septic tanks being a commonly used method.
2.2 Centralized Wastewater Treatment
On the other hand, centralized wastewater treatment utilizes modern and safer equipment. This method is applied in industrial plants that generate pollutants harmful to human health or the environment. Centralized treatment effectively addresses these issues, providing higher environmental safety but at a higher cost. The process typically includes anaerobic stages, SBR, and oxidation ditches. Although the installation cost for centralized systems is not excessively high, the need for continuous maintenance can drive up the overall expenses. Therefore, investors must carefully consider their options to choose the most suitable system for their business operations.
3. Which to Choose: Centralized or Decentralized?
Each wastewater treatment method has its own advantages and disadvantages in ensuring clean wastewater discharge. Decentralized systems are ideal for smaller operations, while centralized systems are better suited for industrial companies. However, both offer comparable levels of efficiency and safety. The choice should be based on factors like specific requirements, costs, and other considerations relevant to the business.
