Did you know that 17 to 20% of industrial water pollution comes from the textile dyeing and finishing industries? They are considered one of the largest wastewater producers as a large amount of water is required for different processes.
With the rise in the economy, meat consumption in India has grown. Nearly 70% of people in India prefer nonvegetarian food. In 2020, the population of India had consumed over six million tonnes of meat. According to the Ministry of Food Processing Industries, India accounts for 2.18 per cent of global meat production. It ranks sixth after China, The United States of America, Brazil, Russia and Germany.
The brewery industry is the most traditional industry that manufactures alcoholic beverages. Beer production requires a large quantity of water, especially in the brewing and filling processes. Even though the production process varies in the different breweries, these industries discharge significant effluents. The brewery industry is considered an important economic segment of the country. However, the byproducts generated, including mashing and yeast surplus, are responsible for causing pollution when mixed with the effluents such as sugar, soluble starch, ethanol and volatile fatty acids.
The dairy industry is the largest polluter of water generating an estimate of 2.5 to 3 liters of wastewater for every liter of milk processed. The efficiency of wastewater treatment management for dairy industries is based on the daily volumetric loading and flow rates. However, it becomes complicated as each milk product requires separate technological cues, resulting in regular effluent composition change.
A wastewater treatment plant is a facility in which a combination of various processes such as physical, chemical and biological are used to treat industrial wastewater and remove pollutants. It’s primary importance is to offer a solution to ensure safety precautions and discharge regulations are followed.
With the alarming rate at which groundwater is disappearing, water is becoming a critical component. Clean water has become more critical than ever in today’s world. We know water covers 70% of our planet, and we always think it is plentiful. However, freshwater, i.e. the water we drink, bathe in and irrigate our farm fields with, is incredibly rare. Only 3% of the world’s water is freshwater, two-thirds of which are frozen glaciers or unavailable for our use. Around 1.1 billion people worldwide lack access to water, and a total of 2.7 billion find water scarce for at least one month of the year.
In a fast urbanizing country like India, where freshwater is scarce, waste water treatment is critical.To address surface water quality challenges in quickly increasing and emerging cities, state and non-state entities have gradually shifted their attention to new innovative wastewater management systems. Wastewater Treatment usually includes three basic stages, which are known as primary, secondary and tertiary. Each stage purifies water to a higher level. In certain cases, just one or two phases are required. The level of treatment required is determined by the intended use of the water and the environment into which it will be discharged.
Sewage treatment through anaerobic processes works effectively in removing biodegradable organic compounds and has advantages of reduction in the amount of the sludge being produced.
The biogas produced during the process also acts a source of energy , making the overall process energy efficient.
The microorganisms in aerobic systems perform their function in the presence of oxygen, whereas in anaerobic systems, the decomposition process is carried out by microbes in the absence of it. Read on to find out more about aerobic and anaerobic treatment technologies, origins, differences, advantages and disadvantages and much more.
Dal Lake, one of the largest water bodies in Kashmir and a world-famous tourist attraction, contributes significantly to its economy through tourism, agriculture and fisheries. In addition, it has been a major source of food and water for the people residing in the area. However, pollution in Dal lake has become a concern in recent times as the water characteristics have drastically changed. Moreover, the unpleasant condition has affected the aesthetic value and has reduced the number of tourists visiting the lake.
