Sewage is wastewater from homes, industries, and businesses. Discharging untreated sewage into rivers or seas is harmful because it contaminates water with disease-causing germs, chemicals, and pollutants. This pollution can make water unsafe for drinking and recreational activities, causing health issues like infections. It also leads to excessive plant growth, reducing oxygen in water, and harming aquatic life. Moreover, it disrupts ecosystems, threatening the environment and biodiversity. Proper treatment of sewage is crucial to prevent these harmful effects on water bodies and living organisms.
Oils and fats should not be poured down drains because they cause clogs in pipes, leading to drainage problems and costly repairs. When released into sewage systems, they accumulate, causing blockages and environmental pollution. Moreover, they hinder wastewater treatment, affecting water quality anRead more
Oils and fats should not be poured down drains because they cause clogs in pipes, leading to drainage problems and costly repairs. When released into sewage systems, they accumulate, causing blockages and environmental pollution. Moreover, they hinder wastewater treatment, affecting water quality and potentially harming the environment. To avoid these issues, it’s best to let oils solidify and dispose of them in the trash or recycle them at designated centers, preventing plumbing issues and protecting the environment from pollution.
Wastewater treatment involves several steps: Screening removes large objects. Sedimentation settles solids, followed by biological treatment where microorganisms break down waste. Chemicals create flocs that settle, clarifying the water. Filtration removes fine particles, enhancing water quality. DiRead more
Wastewater treatment involves several steps: Screening removes large objects. Sedimentation settles solids, followed by biological treatment where microorganisms break down waste. Chemicals create flocs that settle, clarifying the water. Filtration removes fine particles, enhancing water quality. Disinfection kills harmful bacteria. This process results in clean, clarified water safe for reuse or release back into the environment. These steps ensure wastewater is thoroughly treated, meeting quality standards and safeguarding water resources.
Sludge is the solid residue separated from wastewater during treatment. It undergoes thickening to reduce volume, followed by anaerobic digestion where microorganisms break down organic matter. Then, dewatering removes more water, reducing its volume. Treated sludge can be disposed of in landfills,Read more
Sludge is the solid residue separated from wastewater during treatment. It undergoes thickening to reduce volume, followed by anaerobic digestion where microorganisms break down organic matter. Then, dewatering removes more water, reducing its volume. Treated sludge can be disposed of in landfills, incinerated, or reused as fertilizer in agriculture. The process aims to stabilize sludge, reduce its volume, and make it safer for disposal or beneficial for reuse, following environmental guidelines for responsible waste management.
Untreated human excreta contains harmful pathogens like bacteria and viruses. If left untreated, these pathogens spread waterborne diseases like cholera and typhoid, causing illness among communities. Improper disposal contaminates water sources and soil, posing health risks to humans and ecosystemsRead more
Untreated human excreta contains harmful pathogens like bacteria and viruses. If left untreated, these pathogens spread waterborne diseases like cholera and typhoid, causing illness among communities. Improper disposal contaminates water sources and soil, posing health risks to humans and ecosystems. Insects and pests can carry these pathogens, further spreading diseases. Proper treatment and sanitation of human waste through sewage systems and toilets are vital to prevent the transmission of diseases, safeguard public health, and maintain a clean environment.
