Most Common Problems of Sewage Treatment Plants in India


India is a densely populated country, with the number of people only increasing daily. Hence, people live in large groups and communities, increasing the need for proper sewage treatment plants for a healthy and safe lifestyle. These plants need to be equipped to deal with treatment issues on a large scale due to the sheer volume of people residing in one location. Due to these complex requirements, these plants may face specific problems and do not operate properly. This leads to massive issues as having an effective sewage system is vital for the survival of any living community.

In this article, we will go over the most common problems that sewage treatment plants in India face and how these companies can effectively tackle these problems:

The Problems Faced By Sewage Treatment Plants

1. Downstream Equipment Failure

The very first machinery used in a sewage treatment system is the downstream equipement. Using a screening process, this equipement is used to remove any non-biodegradable solids that are floating in the sewage. The most popular examples of these solids found in wastewater include paper, tin, plastic, rags, wood, and containers.

Sometimes, big pieces of such solids are found in the water that is too big for the downstream equipement to process and screen. This could cause damage to the machinery like pipe blockage, wear & tear, and accumulation of materials that hamper the entire treatment process.

Hence, it is crucial to do a quick manual scan of the water before processing it through the machinery to ensure big pieces can be removed.

2. The Treated Effluent Doesn’t Meet The Phosphorous Target

When it comes to sewage treatment plants, the phosphorous target for the wastewater processed through this system is set with the following objectives:

  • Minimize the use of chemicals
  • Achieve a lower operational cost
  • Get license limits for TP

Hence, these sewage plants need to meet the set target. If they are facing difficulties in achieving this target, it is recommended to monitor the chemical dosage used in the system.

3. Strong Odor Issues

Due to the high levels of hydrogen sulfide and organic acids present in the wastewater of India, the sewage treatment plants often tend to stink a lot. Hydrogen sulfide is a foul-smelling colorless gas, which is extremely corrosive. Hence, to get rid of the odor, it is essential to reduce the presence of hydrogen sulfide gas.

How To Avoid The Common Problems Faced By Sewage Treatment Plants

Each plant is unique, and each of them faces its own individual set of problems. Moreover, the common issues listed above can be caused due to multiple reasons, as well.

Hence, if you’re looking for an effective solution to rid your plant of all problems and ensure it is functioning effectively, it is recommended to partner with a company that provides systems that are well-equipped to deal with these issues and don’t require any manual effort. Companies like Thermax are focused on creating a community wherein sewage treatment plants are promoting the message of recycling and reuse!

What are Bi-Drum Boilers? How Do They Work?

Image
Bi-drum boilers are used for purposes of power generation and as process steam generators. This type of boiler is used up to 100MW for generating power. Bi-drum boilers are non-reheat units which are getting wiped out due to high heat rate of the plant. These boilers are used for generating high steam pressure which is used for power generation owing to their ability to accommodate high load of fluctuation and respond to load changes with more agility compared a single drum boiler. The two drums in the bi-drum boiler are connected using a large number of convective heat transfer tubes known as bank tubes or boiler bank tubes. These tubes are about one thousand in number. The bank tubes and the drum at the bottom that contains water will have a water level that will be up to the normal working level of water in the upper drum. The water availability in the bi-drum boiler makes it very adoptable for large load changes. Flue gases enter the bank tubes which are placed towards t...

How Do Electrostatic Precipitators Work?

Image
Reducing air pollutants is vital for human health and the health of the environment. Poor air quality has harmful effects on human health, particularly the respiratory and cardiovascular systems. Pollutants also damage plants and buildings, and smoke or haze can reduce visibility. Industries are largely responsible for causing pollution. They are also the ones who have access to a number of pollution control devices that absorb, filter, dilute, and disperse pollutants. One such device for pollution control is the electrostatic precipitator. This device works by removing particles and smoke from a gas stream using an electrostatic charge. Dust particles travel past wires that have a high direct current (DC) voltage applied, which ionises the surrounding gas. This corona discharge causes the particles to pick up a small electrostatic charge, without impeding the gas flow. Originally designed for recovery of valuable industrial-process materials, electrostatic precipitators are used a...

Quick overview of the Import & Export of Chemicals in India

Image
The chemical industry in India offers building blocks and essential raw materials for numerous industries such as paints, paper, textiles, pharmaceuticals, agrochemicals, soap, and detergents, etc. Let’s go through a few statistics of the chemical industry: The chemical industry in India is ranked 4th in Asia and 6th in the world. The global chemical industry is expected to be worth $4.7 trillion. The chemical companies in India contributes 3.4% to the global chemical industry. As of 2018, the chemical industry (including pharmaceuticals and fertilizers) stood at $163 billion. The Chemical sector in India is expected to grow at 9% per annum to reach $304 Bn by FY 2025. The expansion is anticipated to be pushed by rising demand in end-use segments for Specialty Chemicals and also for petrochemical intermediates. In 2015-16, the Chemical and Chemical Products sector accounted for 2.39percent of the GVA, compared to 2.23percent in 2014-15.18 Note: With India possessing a l...
