Environment Water & Wastewater Waste

Environmental or environmental protection technology are the technical and technological methods to protect the environment and to restore already damaged ecosystems. These methods are developed in the field of Environmental Engineering.

Subject of environmental technology are:

wastewater treatment
Disposal (eg. As waste disposal, incineration, recycling, the creation of landfills)
Water-, soil protection
Air pollution (eg. As odor reduction, gas cleaning)
Renewable energy (eg. As solar, geothermal)
Metrological recording and monitoring of pollutants and environmental damage.
Measurement for the design and verification of pipe networks and pumping stations

Drinking water is water for human needs. Drinking water is the most important food, it can not be replaced.
(DIN 2000 input and guideline)
Drinking water is fresh water with such a high degree of purity that it is suitable for human consumption, in particular for drinking and preparing food. Drinking water may contain disease-causing microorganisms and should contain a minimum concentration of minerals.

Wastewater is by domestic, commercial, agricultural or other use in its properties modified water and its resultant effluent during dry weather water (waste water) and the collected precipitates out of the range of built-up or paved areas flowing water (rainwater). The exiting facilities for treatment, storage and depositing of waste and collected fluids are also considered dirty water.
(§ 54 para. 1 Water Act BRD)

Types of incinerators
Incinerators are available for various purposes in different sizes and designs. Small plants are located in hospitals, to eliminate bacterially contaminated waste locally. By far the greatest proportion is treated in industrial plants, the energy released is used usually in the form of district heating or to generate electricity. Combustion method is usually the combustion furnace to rusting, in part, the fluidised bed by prior treatment of the waste.

Incineration on the grate
In the grate no treatment of the residual waste is required. is charged into the hopper of the plant by conveyor belts or cranes. About the charging device, consisting of a lock and the object table, the garbage is dosed conveyed into the oven chamber. He arrives on the grid, the further promotes the discontinued waste during combustion phases.
In the first zone, a drying of the waste takes place, the excess of 100 ° C followed by evaporation of the water content at temperatures. In the next zone in the temperature range of 250-900 ° C is carried out degassing of the waste. Upon reaching the flash point of the combustion degasification uses that runs incomplete at temperatures of 800-1150 ° C. On the last grate zone the terminal combustion is done.
