What is the effect of industrial waste on human life?
Industrial pollution continues to cause significant damage to the earth and all of its inhabitants due to chemical wastes, pesticides, radioactive materials etc. It affects wildlife and ecosystems and disrupts natural habitats. Animals are becoming extinct, and habitats are being destroyed.
What are the effects of industrial effluents?
Industrial wastewaters entering a water body represent a heavy source of environmental pollution in Nigerian rivers. It affects both the water quality as well as the microbial and aquatic flora.
What are the harmful effects of industrial effluents on environment?
This is because untreated or inadequately treated wastewater effluents may lead to eutrophication of the receiving water bodies and also create environmental conditions that favor proliferation of water-borne pathogens or toxin-producing cyanobacteria.
How does effluent affect living?
If too much fertiliser is applied or applied at the wrong time, leaching into waterways can occur. Water quality in rivers is degraded by effluent. There is also an increased growth of bacteria that take up the dissolved oxygen in the water, preventing fish and other living things from absorbing it.
Why are industrial wastes harmful?
Industrial waste may be solid, semi-solid or liquid in form. It may be hazardous waste (some types of which are toxic) or non-hazardous waste. Industrial waste may pollute the nearby soil or adjacent water bodies, and can contaminate groundwater, lakes, streams, rivers or coastal waters.
What are the effects of industrial effluents on stream?
The untreated industrial effluent continuously contaminates the surface water in the streams and the lakes/tanks. This causes sedimentation of contaminants and the investigations show very high concentration of PHEs in both stream and lake sediments.
Why is effluent important?
The major aim of wastewater treatment is to remove as much of the suspended solids as possible before the remaining water, called effluent, is discharged back to the environment. As solid material decays, it uses up oxygen, which is needed by the plants and animals living in the water.
How bad is industrial waste?
Industrial waste can also be toxic or hazardous waste. If not managed properly, this type of industrial waste can cause harm to humans, animals and the environment by contaminating waterways, such as rivers and lakes.
What are the effects of industrial effluents on natural water bodies?
The effluents of the industries gave a great deal of influence on the pollution of the water bodies, these effluents can alter the physical, chemical and biological nature of the receiving water body.
What is the effect of industrial waste water on the environment?
Waste water from manufacturing or chemical processes in industries contributes to water pollution. Industrial waste water usually contains specific and readily identifiable chemical compounds. Water pollution is concentrated within a few subsectors, mainly in the form of toxic wastes and organic pollutants.
What are the environmental impacts of industry?
Amongst other things industrial process can cause climate change, pollution to air, water and soil, and health issues. Industry is a major cause of air pollution, since the operation of factories results in the emission of pollutants.
What are the impacts of industries on environment?
At the same time, industrial processes can have negative environmental impacts, causing climate change, loss of natural resources, air and water pollution and extinction of species. These threaten the global environment as well as economic and social welfare.
How is effluent treated?
sedimentation allows tiny particles to settle out from still water, which produces sewage sludge and effluent (the liquid which remains on top) the sewage sludge is digested anaerobically by specific bacteria. the effluent is treated with aerobic bacteria to reduce the volume of solid waste.
What are the 3 stages of wastewater treatment?
There are three main stages of the wastewater treatment process, aptly known as primary, secondary and tertiary water treatment.
