Installing an industrial wastewater treatment tank system is essential for environmental protection or water reuse. Join Môi Trường Đại Nam in exploring this topic to select suitable tank models that fit your company’s budget!**
1. Overview of Industrial Wastewater Treatment Tanks
Industrial wastewater treatment tank systems are crucial for removing pollutants in factories. The primary goal is to purify wastewater, ensuring that it is free from organic substances, bacteria, microorganisms, and chemical compounds before being discharged. Currently, each tank is manufactured from special materials suited to different treatment systems. Typically, these systems include sedimentation tanks, anaerobic tanks, bioreactor tanks, filtration systems, and other advanced equipment.
2. Reasons to Build Industrial Wastewater Treatment Tanks
Installing wastewater treatment tanks plays a vital role in environmental protection. Here are the main reasons why installing these tanks is necessary:
- Contributing to Environmental Protection: Wastewater causes severe pollution to water, soil, and air. Therefore, removing pollutants such as bacteria and harmful substances is imperative.
- Legal Compliance: Environmental laws strictly regulate the discharge of untreated wastewater by companies, businesses, or households. Additionally, the penalties for violations are quite high, so installing a wastewater treatment system will help you avoid legal consequences and ensure compliance with the law.
- Modern Design: Today's tanks are designed to accommodate various industrial wastewater treatment technologies. Advanced design optimizes the treatment process and enhances long-term efficiency for businesses.
- High Standards: Due to the continuous workload, wastewater treatment tanks must meet high standards, avoiding leaks or malfunctions during use. This ensures both efficiency and environmental safety.
3. Common and Effective Industrial Wastewater Treatment Tanks
Industrial wastewater comes from factories and businesses, containing many harmful substances that are difficult to treat. Below are the most commonly constructed wastewater treatment tanks:
3.1 Collection Tanks
Collection tanks remove large impurities such as trash and other solid materials. By using trash screens, collection tanks prevent impurities from flowing into subsequent treatment steps.
3.2 Equalization Tanks
Equalization tanks play a crucial role in maintaining stable concentrations and flow rates of wastewater. To ensure effective sedimentation, these tanks use air blowers and mixers to prevent sedimentation and create optimal conditions for subsequent treatment processes.
3.3 Sedimentation Tanks
Sedimentation tanks hold wastewater for a set period, allowing heavy impurities to settle at the bottom. With a depth of 3 meters or more, they collect sludge and ensure sufficient retention time to achieve good sedimentation efficiency.
3.4 Sludge Storage Tanks
After treatment, sludge is stored in sludge storage tanks. These systems are equipped with sludge presses to quickly dry and reduce the volume of sludge, effectively managing sludge waste and saving space.
3.5 Disinfection Tanks
Before wastewater is discharged into the final receiving source, it passes through disinfection tanks to kill bacteria and pathogens. Chlorine or other disinfectants are commonly used, ensuring that discharged wastewater is safe for the environment and human health.
4. Important Considerations when Constructing Industrial Wastewater Treatment Tanks
When constructing industrial wastewater treatment tanks, there are several important considerations that contractors, engineers, and business owners need to address to ensure the project's safety.
4.1 Odor Issues
This is a common issue during the construction of wastewater treatment systems. Odors typically occur during the initial installation phase and may arise in the equalization tank, secondary sedimentation tank, or due to accumulated sludge, especially if the sludge has been left for a long time without cleaning. Therefore, businesses should regularly dredge the sludge. Regular cleaning will help maintain the system’s effectiveness and minimize odors.
4.2 Clogged Pumps
The main cause is the wastewater treatment system operating beyond its capacity, causing pump blades to become clogged with solids or waste. To resolve this, businesses should have a high-capacity pump on hand as a backup and conduct regular inspections. This will ensure the pump operates efficiently, increasing its lifespan and allowing for long-term use.
4.3 Biomass Issues
Dark-colored biomass results from insufficient oxygen during the aeration process. In this case, immediately stop or reduce the amount of wastewater being pumped in and install additional aeration systems to continuously supply oxygen. If biomass forms a dense mixture, it could be due to oxygen deficiency, irregular organic loading, or fluctuating pH levels. To fix this, increase the oxygen supply, adjust the organic loading, and stabilize the pH level in the treatment tank.
