This scarcity of water, a source of deficiencies and illnesses in the populations concerned, is largely due to insufficient or no pollution control actions. This concerns several million inhabitants of the Earth. In fact, companies and communities have an obligation to treat the effluents resulting from their activities. The treatment of these effluents can comprise several stages classified according to their positions in the complete treatment (primary, secondary, and sometimes tertiary). Industrialists, depending on their operating shutdown, can discharge their effluents directly into the network or have an obligation to perform pretreatment or complete treatment of their effluent. During a complete treatment, the discharge can be carried out in a natural environment such as a river. The treatment can be carried out by different processes such as physicochemical processes (rather primary), biological treatment (rather secondary), oxidative treatment with ozone, for example, or adsorption on carbon (rather tertiary). All of these treatments make it possible to eliminate the various forms of pollution, mainly carbonaceous forms (hydrocarbons, alcohol, carboxylic acid, for example) and nitrogenous forms, which may be present in solid, colloidal or dissolved forms.
What about domestic water treatment?
There are two methods of sanitation for domestic water Individual and collective sanitation. So number of SEWAGE TREATMENT PLANT STP COMPANIES IN RIYADH DAMMAM JEDDAH SAUDI ARABIA can do this work As part of collective sanitation, domestic water-related to activity and human consumption is collected by networks that are connected to a treatment station. Water – valves corresponding to sanitary water from toilets and grey water, or grey water, coming from washrooms, bathrooms, and kitchen. In the context of urban effluents, the inhabitant equivalent is used to quantify the pollution that is treated in a wastewater treatment plant.). For more detailed information, there are water information systems that explain water treatment, as well as sewage sludge treatment to consumers. These water information centers regularly publish downloadable online reports.
