The use of wastewater for a variety of purposes – such as cleaning up water used in industrial processes, or water used for domestic purposes – has always been a controversial issue. This is especially true in countries where landfills have been developed and people have started to take for granted the water that runs off their bodies.
As far back as the Roman Empire, it was known that kitchen waste was turned into drinking water. Today, many people still drink from dirty drinking water sources, which is why wastewater is so important. As mentioned above, it is quite common to find that kitchens all over Latin America are being used as compost sites. Such indirect recycling is especially common in the large river systems of Latin American. But even in these systems, less direct reuse is possible – the technologies to recirculate wastewaters as potable water or other processing waters is a technically achievable option for many industrial and agricultural purposes (including for washing water or other sanitary purposes) and can be quite affordable.
There are two methods of liquid wastes – the ones that are solid and those that are semi-solid – and the use of a waste water treatment plant is the most effective way to remove these two types of waste from the water system. One method is known as direct flow wastewater treatment (or wastewater treatment plants), and the other is known as indirect or secondary treatment.
When you take a sewage plant out of operation, for example, you have a number of options. You could use an alternate source of water, or you could use an alternative type of treatment for the solid wastes that are left behind. If your water supply is contaminated by chemicals, you could use a chemical-free sewage treatment facility to remove these chemicals from the water. However, the fact that the water is not clean enough to drink and use means that it would need to be treated before you could drink it.
In contrast, when you treat your solid wastes, the only problem that you are left with is the fact that you have to store all of the solid wastes in one place in order to manage them properly. Most of the time, this happens to be in the form of a landfill site. So, most of the times, waste water treatment plants are built near the landfills, and there they can take care of the liquid wastes that are left behind by the industries. These waste water treatment facilities have the capacity to treat the solids without the need for storage tanks, and containers.
The water that is pumped into these waste water treatment plants comes from an underground aquifer, and is usually brought up into the underground water table. This then passes through a special treatment plant, called a wastewater treatment plant, which removes all of the solids and salts that are found in the water. After this, the water passes through a filtration system, called a distiller, which breaks the water molecules down into the desired water content and then passes the processed water into a tank.
