Water is, aside oxygen, a vital element for life on earth. Access to clean drinking water is mandatory for life to go on as it is today. As the world's population is increasing more and more and the water sources remain at the same level, timely wastewater treatment is of the essence so that the natural water reserves refill at a constant pace. With the wastewater training IN, you stand to benefit from a deeper understanding of the process.
In the next process, known as secondary treatment, biological matter that has either dissolved into or is being suspended in the water is removed. This is usually done using water-borne micro-organisms that are kept in a controlled habitat. Sometimes, a separation process is again required to remove these micro-organisms before the third and final process.
Treated wastewater should be environmentally safe for reuse as fertilizer, garden and lawn watering, industrial applications, aquifer recharge and dust suppression. There is the advanced technology today that makes it possible to treat sewage to be safe to reuse as drinking water.
After this step, the water is usually discharged into a stream or river, but can be used for other purposes, such as irrigation for a golf course or agricultural land. In some cases, water that is clean enough may be reintroduced for groundwater recharge.
Contaminated water comes from household waste from toilets, showers, bathtubs, sinks and kitchens. It also comes from industry and commerce. Greywater does not contain human waste and is treated to be used for landscape irrigation and wetlands that are artificially created to restore wildlife habitats for migratory and native birds and land reclamation.
Another wastewater treatment method is filtration and this process implies that the water that has passed through the sedimentation stage now has to pass through a series of filtration beds. These filters withhold any leftover suspended mater in the water. The filtration beds are usually made out of artificial nets or membranes with specific thickness requirements as to provide a certain level of cleanness to the water.
As all the chemical treatments may add a specific odor to the water one of the final methods of sewer treatment should be aeration. This is the air exposure of the water so that it returns to the odorless stage. Aeration, aside from oxygenation, means also the removal of any leftover volatile organic substances or compounds.
Pre-treatment that removes large pieces and debris such as branches. Screening also removes large pieces that are smaller than the debris removed in pre-treatment including plastic packets, cans, rags and sticks. This is usually done with a raking bar but can be done manually.
As better ways of treating wastewater are found, conservation of other resources such as land and energy also occur, as less of both are needed. It is hoped that through time and advancing technology, more effective and efficient means of treatment and recycling can be found to help conserve this resource. We only have one earth, and while you do your part in conservation on your end, we will keep advancing to make sure that we continue to do ours.
