To ensure your wastewater treatment plant functions efficiently, you must provide periodic maintenance and inspect your system from time to time. Any lapse or failure to do so may lead to irreparable damages in the pipeline and even permanent loss of certain parts.
Maintaining a sewage treatment plant is not tough. You have to be regular with inspection. Upon witnessing a fault or damage in the system, you must act on the issue immediately to save the plant from irreparable damage. There are an array of factors responsible for the smooth functioning of a sewage treatment plant. Let us guide you to the easy and effective methods to maintain your wastewater treatment plant.
Maintenance Guide for Optimal Wastewater Treatment Plant Performance
- While doing daily rounds, ensure that the system’s pressure is within limits and not exceeding the subscribed range.
- Inspect the airlift return to ensure the wastewater treatment plant is working correctly. You can check the flow via the clear plastic pipe laid on the installation. You will witness a clear sludge flowing through the tubes to the aeration chamber. It shows that your system is working correctly.
- To ensure the enhanced efficiency of your plant, a bio-pac is installed every week on the system. The bio-pac has aerobic bacteria, activated when placed in hot water.
- Over time, the sludge accumulation in the aeration tank results in sewage increase. This sludge accumulation or suspended dirt particle is measured in mg/litre. You are then required to take a sample of the sludge in a conical flask given by the manufacturer and fill the flask up to the 1000ml mark. The sludge sample collected is then allowed to sit in the flask, and then the reading of sludge content is checked.
- Along with checking the sludge content, you must inspect the level of biological oxygen demand (BOD). You must ensure that the BOD is not above 50 mg/litre. The BOD sample is assessed by incubating it at 20 degrees and properly oxygenating it. The quantity of oxygen absorbed by the sample over five days is observed. This process is to inspect whether the aerobic bacteria successfully free required oxygen for a full breakdown of sewage water.
- It is not just the sludge and oxygen saturation you must inspect, ensure that your system’s internal coating is free from cracking and blistering. If you witness any damage in the pipes, get the tanks emptied immediately and call for maintenance to get the necessary repairs done timely. Ensure all the required precautions are taken while cleaning the tank as the tank may contain toxic gases. You can use a draeger tube to check the gases. A draeger tube is a tube where samples of various gases are collected before entering the tank.
- If your sewage treatment plant is installed with a UV disinfection system, don’t forget to change the UV lamp as recommended by your manufacturer.
- A wastewater treatment plant has high and low level-limit switches to cut-in and cut-out discharge to the overboard pipe. Ensure these switches are in good working condition at all times.
- When the sewage treatment plant is running, ensure your stand-by sewage water discharge pump is kept on auto.
- If you incur a blockage in any sewage or pipeline, you can always use a connection meant for back flushing. This method is used to unclog your sewage pipelines. However, before you operate the back flushing technique, have a word with your manufacturer to avoid making mistakes. It will be best if you summon help to unclog the sewage pipe for you if you are a novice at this.
Ideally, sewage pipe cleaners are instructed to use tested chemicals provided by an expert so that no clogging of lines occurs. However, ensure that there is no overuse of said chemicals as it may lead to killing aerobic bacteria. If the aerobic bacteria is harmed, it may result in a decrease in oxygen concentration in water which in turn will hamper the purifying process.
Resolving Common Issues in Wastewater Treatment Plants
Signs of Inefficient Operation
Several indicators point to a sewage treatment plant running inefficiently. One of the most noticeable signs is the presence of foul odours, which typically indicate problems with the aeration system or insufficient bacteria activity. A reduced flow of water through the system may point to blockages or malfunctions in pumps or valves, while increased sludge levels could suggest issues with settling or filtration. Visual cues, such as cracks or leaks in pipes or tanks, should be promptly addressed to prevent further system deterioration and ensure optimal functioning.
Dealing with Pipe Blockages
Blocked pipes are a common issue in wastewater treatment facilities. To clear a blockage, start by shutting down the relevant sections of the system. Back-flushing is an effective method for dislodging debris. First, reverse the flow of water to push the clog out. If that doesn’t work, a high-pressure water jet may be necessary to break up more stubborn obstructions. It’s important to avoid using harsh chemicals that could damage the pipes or disrupt the microbial ecosystem. Always handle equipment carefully and ensure that pressure levels are safe to prevent pipe rupture.
Maintaining Aerobic Bacteria Levels
Aerobic bacteria play a crucial role in breaking down organic waste in a wastewater treatment plant. If the population of these beneficial microorganisms drops, treatment efficiency can decline. Regularly monitor oxygen levels, as aerobic bacteria thrive in well-oxygenated environments. Keep track of chemical use, as excessive or improper chemical dosing can harm bacterial growth. It’s important to strike a balance between disinfection and preserving microbial health, as effective biological treatment relies on a healthy bacterial population.
Preventative Maintenance Tips for Longevity
Implementing preventative maintenance measures is key to ensuring the longevity of your wastewater treatment plant. Regular upkeep helps to avoid system downtime and costly repairs.
Inspections to Avoid Expensive Repairs
Routine inspections are essential for identifying issues before they become expensive repairs. Pay particular attention to internal coatings, checking for cracks or blistering that could lead to structural damage. Regularly inspect UV lamps, as these devices need to be replaced after a certain period to maintain their disinfecting efficiency. By staying on top of these inspections, you can catch minor problems early and prevent major breakdowns.
Safety Precautions During Maintenance
Safety should always be a priority during plant maintenance. Use Draeger tubes to assess for the presence of toxic gases in the air. This helps to identify hazardous situations before they become dangerous. Ensure staff wear appropriate personal protective equipment (PPE), including gloves, goggles, and respiratory protection, to prevent exposure to hazardous chemicals or gases during maintenance activities. By following proper safety protocols, you can protect your team and maintain a safe working environment.
What to Look for in a Wastewater Treatment Plant Solution Provider
Choosing the right wastewater treatment partner involves several important factors. Experience is key — an experienced installer will be able to assess your plant’s unique requirements and implement effective solutions. Look for a provider that offers customisation options, as one-size-fits-all solutions often don’t provide the long-term efficiency you need.
Additionally, ensure that your partner offers post-installation services such as regular maintenance, troubleshooting, and upgrades. Another critical consideration is energy efficiency. Opting for energy-efficient systems can significantly reduce operating costs, making the treatment process more sustainable in the long run. With the right partner, your wastewater treatment plant will run smoothly, helping you meet regulatory standards and environmental goals.
