What are the cause of overload problem in WWTP?
A plant operator can identify if their wastewater system is overloaded in a number of ways, including by using a control system. A good control system will notify the operator when something is wrong with the system. There are other non-measurable signals outside of a control system, such as an exceptionally strong stench or sludge that appears to be excessively old. This could cost you a lot of money, due to which it's critical to have effective controls in place to evaluate and analyze your data consistently.
Causes of overloading
Overloading can be caused by a variety of factors:
- The industrial facility is now connected to the public sewer system.
- Because the village/town is expanding, the population is expanding as well.
- The factory's production, and thus the volume and/or concentration of effluent, has increased.
- The factory released a vast quantity of organic chemicals all of a sudden (for example, waster products)
- Someone dumps wastewater into the sewerage system without warning (possibly illegally)
What are the options for resolving these issues?
- If the inflow is only exceeded at particular time of the day and there are problems, the problem can be solved by incorporating the buffer tank into the system. The buffer tank's purpose is to collect surplus wastewater and discharge it when the flow volume is lower. A previously unused tank or a new tank can be used as a buffer tank.
- If there is an issue with low oxygen levels, a variety of options must be examined.In this circumstance, a buffer tank can aid since it eliminates the places with the most load and hence the greatest need for oxygen. Less efficient machine functioning is also considered if the blowers are older and have not had regular maintenance in the past. Blower maintenance may be able to address this problem.Cleaning the air distribution system with diluted muriatic acid or a mild organic acid solution can enhance oxygen delivery. This guarantees that pollutants from the water or air side of the membranes are eliminated through the pores of the elements.
- It is crucial to keep an eye on how evenly the air is distributed around the space. Some of the rubber membranes of the distribution system's components can be damaged, burst, or entirely rip. They must be replaced in this instance.
- If the system is overloaded with a high concentration of organic matter, the amount of sludge (sludge concentration) in the activation that removes the organic matter might be increased.In this instance, extra caution should be taken to ensure that an increased number of microbes receive the oxygen they require to function properly.
Other ways to solve the problem
1: Conserving water can aid in the reduction of pollution in our waterways. Since users use more water in houses, wastewater treatment facilities must process more water.
Taking the following steps will help to lower the amount of water that needs to be treated and the risk of sewage overflows:
>When not in use, turn off faucets.
>Fix any leaky faucets or pipes.
>Showers should be shorter.
>Install low-flow faucets and showerheads, as well as low-flow and dual-flush toilets.
>Replace obsolete dishwashers and washers with newer, more energy-efficient, and water-saving versions.
>Install rain barrels to collect rainfall and use it to irrigate the plants
2: Many collecting systems overflow due to the accumulation of fats, oils, and grease. Grease, oils, and fatty substances thrown down through kitchen drains in homes and restaurants can clog sewer systems.These build-ups might result in sewage overflows or backups into residences. Allow fats, oils, and grease to cool before disposing of them in the garbage, rather than throwing them down the drain. Grease traps should be installed in restaurants, and used oil and grease should be collected for proper disposal.
3: Even when classified as flushable, many products that are regularly flushed down the toilet or poured into kitchen sinks can cause damage to sewer systems and wastewater treatment equipment:
-Personal Hygiene Products Diapers Baby Wipes
No matter how little, do not flush any of these items down the toilet. Toss them in the garbage.
To avoid malfunctioning of our Waste water treatment plants and Sewage treatment plants, it is essential that we follow proper guidelines and measures to avoid overloading problems.
As manufacturers of various waste water treatment products, we at Netsol Water Solutions, suggest to keep in mind all the measures discussed above and follow them consistently.
