Sewage treatment plants (STP) acts as a boon in keeping the environment safe. And undoubtedly, the importance of STPs cannot be ignored in today's scenario. While it is easy to maintain a sewage treatment plant, one may still face many problems in its working. This usually happens when one or the other part of a plant is not working well.
This article is written to provide you with information regarding some common problems that one may face in sewage treatment plants. But before we move forward, it is important to understand the meaning of sewage treatment plants in brief.
What is a Sewage Treatment Plant?
A sewage treatment plant is a wastewater treatment plant that aims to remove the contaminants from the sewage and further reproduce such kind of water that is reusable and fit to be discharged in the environment. The water so released does not harm the environment. Sewage wastewater is generally obtained from households, factories, industries, etc.
The treatment plant works mainly in four broad stages:
Stage 1: Preliminary screening is where all the solids and non-bio-degradable wastes are separated from the sewage. This is done to ensure that the filters in the other stages do not get clogged and damaged.
Stage 2: Primary treatment plants treat the Wastewater before it becomes polluted. In this plant, mainly the sludge and all the solid particles get settled at the bottom of the tank. The water so filtered is sent to the following processing unit, i.e., the Secondary plant.
Stage 3: Secondary treatment plants take the primary treated water and further treat it to remove bacteria and other pollutants. In this process, the water is treated to destroy all the bacteria, viruses, etc.
Stage 4: Tertiary treatment plants are the final stage where water comes from a well or natural aquifer instead of a pipe or river. In this process, the water is further treated with disinfectants to make it better in taste and odor.
Now we have looked at the basic concept of sewage treatment plants, let us understand the common problems one may face in a sewage treatment plant.
Common problems faced in a sewage treatment plant
A sewage treatment plant is easy to operate and maintain the machine. However, it still requires some basic attention from the users using it. Some of the most common problems faced by a STP plant have been described here as follows.
- 1. Excessive heating of blowers and lack of air in the system: The lower amounts of oxygen will lead to the deterioration of the drainage system and create a form on the system's surface. There are many similar problems like this that one may face while using a sewage treatment plant. The presence of less oxygen in the system would be a serious implication if it were for a long time. Short-term fluctuations may not necessarily cause a problem.
- 2. Leakage of sludge in a settling tank: Generally, the leakage of sludge happens when oxygen or nutrients are deficient in the system. This leads to paving the way for bacteria and other microorganisms to grow and form chains to replicate themselves. This also happens when the nitrogen and other solid materials reside in the sedimentary tank for a long time.
- 3. An excessive amount of chemicals: Inadequate required chemicals such as phosphorus, nitrogen, ammonia, etc., may cause the sewage treatment plant to not work properly. There are various ways to reduce the COD (Chemical oxygen demand), like removing nitrogen, the process of denitrification can be adopted.
These were some of the common problems faced in the sewage treatment plant. If you are an environmentally conscious person and want to save the environment, it becomes very necessary to discharge the waste after properly treating it.
