Biochemical Oxygen Demand is a term all of us come across in most of the articles on water pollution. In this blog, I will walk you through Biochemical Oxygen Demand, its significance and measurement. Before delving into Biochemical Oxygen Demand we should first understand the concept of Dissolved Oxygen (DO), its significance and measurement.
The ozone layer is an area of the earth’s stratosphere that contains high levels of ozone (O3) and protects the planet from the sun’s harmful ultraviolet rays. It can absorb roughly 97-99 percent of the sun’s damaging UV radiation, which otherwise can kill life on the Earth.
The environmental Laws of India help to ensure the protection of the environment and other natural resources and to prevent pollution. In this blog, we will discuss the major Environmental Laws of India and their provisions. Let’s begin with the background of the formation of Environmental Laws and the Ministry of Environment and Forests (MoEF).
Sustainable Waste Management has become the need of the hour with the ever-increasing amount of garbage that humans generate. According to the United Nations, around 11.2 billion tonnes of solid garbage are collected worldwide, with humans accounting for nearly all of it. As a result, we must devise plans for long-term sustainable waste management.
Aeroponics is one of the major techniques in indoor farming which is becoming popular these days due to greater yields and the ability to control the growing environment. Greenhouse and vertical farming are the two main types of indoor farming.
Landfills are a regular occurrence all over the world, owing to the rising volume of trash generated by our homes, schools, offices, hospitals, and markets. The rising number of landfills around the world is largely due to increased urbanization and population growth rates.
Land pollution has disastrous effects, particularly on the survival of animals and humans, as well as in the quality of soil and water. Human activities have increasingly ruined and degraded land since the dawn of industrialization, producing diseases in humans and animals and limiting the capacity to support ecosystems and varied life forms.
Tertiary wastewater treatment, also known as advanced wastewater treatment, is the third step of wastewater treatment. After secondary treatment, tertiary treatment of effluent entails several extra procedures to minimise organics, turbidity, nitrogen, phosphorus, metals, and pathogens. Tertiary treatment of wastewater makes it ready for reuse. Some examples of reuse include:
Globally, 44% of sewage is not safely treated, according to UN-Water 2021. Releasing untreated sewage into water bodies pose a great threat to humans as well as the environment. But, how do we understand the quality of sewage and the number of pollutants in it? This blog let me walk you through the basics of sewage, its sources, types, and quality indicators.
Primary treatment for wastewater involves temporarily storing sewage in a calm basin where heavy materials sink and oil, grease, and lighter solids float to the top. Wastewater reaching a treatment plant through pipes first undergoes primary treatment irrespective of its source.
