What is Blackwater?
Blackwater is a waste water that is loaded with biological material such as feces or grease. Many people call Blackwater as "wastewater". Because Blackwater contains hazardous materials, treatment must be used or re -used, otherwise it could be a source of disease. There are a number of ways to deal with Blackwater, since the establishment of domestic toilet composting to the implementation of an inert waste, to rinse black water through the municipal sewage system, where it eventually ends at a wastewater treatment plant to treat and dispose safely. Human waste is generally considered dangerous, especially when people are ill because they can contain a number of bacteria that could potentially be handed over to others. Many people are also considered to be kitchen sinks as a source of black water, because they contain fat, oils and pieces of food that could go to yellow or carry pathogens. In addition, the water of the laundry from the house with noA powerful person or child could be considered black water because it would probably be pathogens.
Historically, people came up with different ways to handle Blackwater because it is a ubiquitous problem. It is important to insulate black water from drinking water sources, including water and surrounding rivers and streams. In rural areas, this is often done by means of a septic tank that allows pathogens in black water to disintegrate before leachwater release; Most septic tanks must be pumped regularly to remove solids.
people also used eccentrics, basically composting their black water into the pit in the ground, and also composting toilets and buckets in the house. In fact, in some periods, human waste was actually a valuable product, and it would be a collection "Night Soil Men" who would ever pay a small fee for the privilege; Urine could be used in růZné industries, from ammunition to laundry, while feces would be used as a fertilizer.
The use of sewage systems for handling Blackwater is also relatively old, with some examples of such systems in Asia and the Middle East extending to 4000 BCE. Historically many such systems simply threw Blackwater somewhere else or in holding tanks and sump, which were imperfectly designed for the content and decontamination of waste. Modern sewer systems are relatively advanced, with complex treatment plants that are able to render inert waste water and sometimes sufficiently safe to use on agricultural crops.
