What is Grey water and How does it differentiate from Sewage water?
What is Grey water?
Greywater is wastewater from plumbing systems other than toilets, such as hand basins, washing machines, showers, and baths. Greywater can be safely reused in the garden if handled properly. Recycled grey water is commonly used in irrigation and built-in wetlands – as long as no harmful chemicals are present. Grey water containing food particles can be used to irrigate plants; it can also be used to wash clothes and clean bathrooms. Grey water is valuable in areas where water is scarce.
What is Sewage water?
Sewage, commonly known as blackwater, is wastewater from toilets and bathrooms that contains faeces and urine. Because of pathogens and grease contamination, kitchen and dishwasher water is also considered black water. It is also known as sewage or brown water, and it can spread diseases and bacteria that are harmful.
Difference between grey water & sewage water:
Greywater is the cleanest water from sinks, washing machines, bathtubs, and showers.Greywater has a low contamination level, making it easier to treat and process.As long as no harmful chemicals are present, recycled greywater is commonly used in irrigation and constructed wetlands.It can even be used directly in home gardens if there are no harmful chemicals in it, such as soap and detergent, that can harm the plants and soil.Greywater that has been recycled can be used for irrigation and in the construction of wetlands. Food particles in greywater from the sink can nourish plants. It can also be used to clean and flush toilets.In times of drought, recycled greywater is extremely beneficial. Greywater from washing dishes or clothes can even be used to heat water for bathing, thereby reducing energy consumption.
Blackwater is the best water from toilets and bathrooms because it contains faeces and urine.Waterproof kitchens and dishwashers are also classified as Black Water due to pathogen contamination. It is also known as "she waits for groundwater" and can carry diseases and bacteria, both of which are potentially harmful.It can also refer to floodwater, which is typically caused by overflowing bodies of water as a result of heavy rain, typhoons, hurricanes, or tsunamis, and which mixes with sewage water, which can be contaminated with bacteria.
To destroy bacteria when recycling and treating blackwater for use as fertilizer, it must be properly processed and decomposed. Composting generates heat, which can kill bacteria in blackwater. Composting and vermicomposting toilets are now available. Some industrial and commercial organizations are already utilizing them to aid in the reduction of blackwater.
Although some argue that recycling blackwater and greywater in homes for use in washing machines encourages people to use more water rather than conserve it, using recycled wastewater is still beneficial, particularly in areas where water is scarce. People should be properly educated and informed on how to use water in a way that contributes to its conservation.
· Blackwater refers to wastewater from toilets, whereas greywater refers to wastewater from sinks, dishwashers, bathtubs, and washing machines.
· Blackwater contains disease-carrying bacteria, whereas greywater contains fewer contaminants.
· Recycled blackwater can only be used as plant fertilizer, whereas recycled greywater can be used for irrigation, flushing toilets, and cleaning cars and floors.
· Blackwater poses a greater risk than greywater.
