What are the Difference between grey water and black water?
Wastewater is divided into two types: blackwater and greywater. Although, they are both wastewaters, their levels of contamination differ, necessitating distinct treatment. Both types can be recycled using treatment systems, and are frequently used for irrigation and cleaning.
Let us learn the distinctions between blackwater and greywater.
What is Blackwater?
Blackwater is effluent from toilets and bathrooms that contains feces and urine. Water from kitchens and dishwashers is also considered blackwater, due to bacteria and grease pollution. It is also known as sewage or brown water because it can include illness and bacteria, both of which can be hazardous.
How to treat Blackwater?
To treat blackwater, biological or chemical treatment and disinfection are required. There are various approved outdoor treatment systems available.
The aerated system is the most popular wastewater treatment and reuse method, and it consists of the following steps:
1. Wastewater sediments settle;
2. Effluent is aerated to aid bacterial decomposition of organic matter;
3. Chlorine pellets are used for disinfection.
4. Microfiltration/Reverse Osmosis units are also available for home use.
What is Grey Water?
It is wastewater produced by sinks, washing machines, baths, and showers. It has lower contamination levels, making it easier to treat and process. As long as no dangerous substances are present, recycled greywater is routinely employed in irrigation and created wetlands.
Greywater containing food particles can be utilized to feed plants and can also be used for washing and flushing toilets. Greywater is valuable in areas where water is scarce.
How to treat grey water?
Greywater can be utilized in gardens with little or no treatment by using a subsurface irrigation system, to evenly distribute water across the area. For untreated greywater, this procedure is safer; nonetheless, all treatment recommendations are dependent on the state of the greywater.
For people who do not have access to the mains or are unable to gather enough rainfall for indoor use, greywater provides a cost-effective alternative. Reusing treated greywater for toilet flushing can save an average home, 50L of potable water per day.
How to ensure Greywater and Blackwater water quality?
The quality of reused water is determined by the wastewater treatment system, the past usage of the water, and the chemicals used at the source. To simplify the treatment needs, consider the following:
1. Use natural cleaning solutions instead of harsh chemical cleaners;
2. Use low or no sodium laundry detergents, soaps, and shampoos;
3. To guarantee that water may flow through, clean and replace your lint filter;
4. Do not pour household chemicals down the sink;
5. In the kitchen, use a sink strainer to prevent food scraps and other solid materials, from entering the wastewater treatment facilities.
Netsol Water provides cost-effective waste and wastewater treatment solutions, for controlling and managing gaseous emissions, odours, fat, grease, sludge, sewage, greywater and blackwater.
Both grey and black water are kinds of wastewater. Grey water is typically characterized as water from sinks, baths, showers, and washing machines, whereas black water is water from toilets. Grey water, because it contains fewer impurities, can be safely reused or discarded with no or no treatment. However, depending on local rules and regulations, the definition can vary greatly.
