Additional Information About Wastewater Management

By Darren Kielich


Wastewater Purification - Techniques and Facts

When we say management or treatment of wastewater, it pertains to the procedure done to remove, separate and destroy the hazardous or damaging contaminants in wastewater. With this procedure, it is ensured that about 99% of the contaminants and hazardous elements found from used water or raw water supply are destroyed or removed. By using this technique, we are certain that the processed water that enters your house is safe and potable.

To remove the contaminants from used or raw water, there are lots of techniques employed including aeration, sedimentation, use of intake filters, ingestion of chemicals to treat water and filtration. Among the wastewater treatment procedures, ingestion filtering is the most uncomplicated and stress-free option you can follow in purifying used water, but you cannot generate clean drinking water from it. Filtering of wastewater intake is carried out by placing numerous sizes of water sieves to filter out the hazardous elements and impurities prior to harvesting and gathering of effluent or sewage water in wastewater disposal and treatment plants.

When the purification of wastewater involves the use of chemicals, it is known as chemical wastewater treatment. In this procedure, diverse disinfectants or chemical sanitizers are used such as iodine, ozone and chlorine.

Another wastewater or sewage water remediation used today is the sedimentation. It is one type of water purification which entails the storage of water in a container for a period of time to let the sediments and residues settle below the holding equipment before forwarded to another treatment process. This procedure further removes and sieves minute water residuals before they disinfection stage.

The water produced from the sedimentation stage is then forwarded to another phase which is the filtration stage, which involves the entails the use of different bed filtration layers to filter out the tiniest deposits in water. The filters used in this phase have the ability to sieve the remaining and suspended materials in the wastewater. This process makes use of varied thickness and sizes of filter membranes and nets to provide advance filtering and cleaning of water.

Another technique undertaken to ensure the production of odorless water is the aeration method. This is one of the last stages in wastewater purification procedures to ensure the generation of odorless water. In this process, the resultant and pungent smelling water is freely exposed to the air to remove its chemical odor and to make it odorless again. Moreover, oxygenation is one another wastewater procedure to remaining substances and materials in treated water.

Apart from the methods mentioned above, reverse osmosis is another advanced wastewater management technique which has the ability to convert the salty ocean water into potable water fit for drinking.

Oxygen is not the only element needed to survive here on this planet because we also need the universal solvent, water. It is a obligatory element needed to live and to sustain life on this plant. Because its importance, it is a necessity for everybody to drink clean water daily. Because of the constant rise of human population at present, it is sad to note that our supply of clean water in not increasing. Because of this situation, wastewater management options are timely efforts to guarantee continuous resource of clean water.
