What are the different types of black water treatment?
black water treatment methods use physical, biological and chemical methods to treat solid and liquid organic and inorganic waste, commonly known as waste water produced by people through body excretion and domestic activities, as well as agricultural, industrial and commercial activities. The aim is to remove solids, decompose organic compounds, eliminate microorganisms that cause the disease, remove harmful chemicals and prevent or eliminate offensive and harmful odors and soil color. Different types of black water treatment include septic tanks, drainage pools, soil outflow fields, chemicals, biodigests, toilet composting and black water recycling systems. This part contains bacteria, viruses and protozoans that cause people's disease. Black water can also contain harmful inorganic chemical elements such as nitrogen and phosphorus, which are commonly found in fertilizers, as well as potentially toxic heavy metals such as cadmium and mercury.
Septics and soil outflow fields were and remain the most common type of black water treatment system on site in the United States for homes and small groups of houses that are not associated with centralized, usually municipal, wastewater or sewage plant. They usually use physical and biological means to treat black water. The first is percolation and filtration - through gravel, sand and activated coal. It uses anaerobic and aerobic digestion by naturally occurring bacteria for water treatment.
The treatment of black water may also include the addition of chemicals such as chlorine, to disinfecekut black water. In addition, chemicals can be added that cause reactions that lead to the elimination of harmful organic and inorganic substances. At the opposite end of the quality scale, pool, swimming pools or CESS sumps have long been used as often cheaper alternatives because they are sealed tanks designedThe day so that they hold the waste water until it is exhausted and transported elsewhere for treatment.
alternatives that seek to imitate the way of nature treatment of black water are also used because they are considered less ecologically harmful. These include biodigests, wetlands made by man and reed beds, composting toilets and recycling systems of black water. Biodigestry usually strives to treat black water more efficient and efficiently using anaerobic and aerobic digestion. Plants that absorb nitrogen, phosphorus and even metals can be planted in a wetland or reeds.
Black water recycling systems form another category of SYS treatment of black guide. In general, they also usually use different types of physical, biological and chemical methods to treat black water. The difference between this and other types of treatment is that the treated water is then recycled back to the black water loop than to be released.
