What and how does threaten water?
Sewage treatment plant (Place where they clean water)
During trips to sewage treatment plants we learned purification methods and how we can maintain the purity of water.
Sewage treatment - is the combination of equipment for the purification of industrial and municipal wastewater prior to discharge them into rivers, lakes, sea, ground.
That I purification. These processes are designed to remove solids from the waste-water treatment and thick floating suspended mineral and organic.
The primary aim of biological treatment of sewage effluent is to remove the biological pollution.
Chemical methods apply to the disposal of wastewater are ceasing
biological substances do not decompose.
Protection of water - an interview with a sewage treatment employee plant in Bogatynia (my father)
What most threatens the water?
-- Water resources are limited. We do not have an excess of water and cannot use it without restrictions. Poland belongs to those European countries, where water is the least. It is therefore necessary to ensure its rational use.
What reduces water resources?
-- First of all, the climate has an impact on the quantity of water in its natural circulation and the pollution that causes it is not always water can be re-used. Huge quantities of water consuming industries, agriculture, and we consumers of tap water.
Biologial reactor and biological deposits
Is it possible to remove impurities from the water?
-- Of course, we can, but there are needed complex installations for this, which are very expensive. One type of equipment used for the treatment of water surface before the lead, to tap, a second type of device purifies waste water before discharge of pollutants into the river. The more pollutants that water is more expensive.
What pollutants in the effluent are the most difficult to eradicate?
-- Unfortunately, many of them can not be removed. Mostly, they are called. heavy metals (lead, zinc, manganese) and petroleum products (crude oil, motor oils, gasoline). Among difficult to remove pollutants are detergents. They contain a lot of phosphorus, which causes overgrowing rivers and lakes. Overall, the pollution of rivers brought to take oxygen from water, which is essential to life animals and plants. If the lack of oxygen in the river, it will not be in it also plants and fish. It is said that as they live crayfish in the water it is very clean.
Secondary settling vessel
And what most pollutes our Miedzianka?
-- Our most damaging river drainage sewage from buildings, which have no sewage systems. In addition, some residents of various objects thrown there, and if you pour out the worst harmful preparations: solvents, paints, oils.
Hall of sludge dewatering
How come the water that goes into our taps?
-- Approximately 80% of water drawn from lake Witka. It flows by pipes to our Department of Water Conditioning in Zatonie and there is treated. And is pressed to tanks in the Chopin street in Bogatynia. The rest of woater comes from water shots located in Jasna Gora, Opolno Zdroj and Markocice. In Bogatynia such inclusion is in the vicinity of the border crossing.
The control computer
And what happens to litter emerging in our homes?
-- Litter drain system goes to sewage treatment plants along Turowska and thence to the river Miedzianka. Sewage treatment in Little Rock meets the highest European standards.
How to clean the waste water?
-- The main object of a treatment plant is a biological reactor, in which the competent purification process. Removed are in it, inter alia, Related harmful nitrogen and phosphorus. Micro-organisms, for which the pollution of food are called sediment.
What can I do to protect water against pollution?
-- Consider be aware that our lives causes interference in the environment and therefore we have to operate in such a way that this interference was the smallest. Treat the environment like so lent it from your grandchildren. We must do everything so that future generations can enjoy a clean environment.
