As the name suggests, wastewater treatment is the process of recycling the water by removing waste. In some parts of the world, it is called water reclamation where you reclaim, so to speak, the property of clean water.
Did you know that wastewater undergoes different processes in order to become useful again? Aside from that, there are two types of treatment facilities: chemical and biological plants.
While you only see these big wastewater treatment clarifier tanks in some commercials showing the separation of solid wastes from the water, it is just one part of the treatment operations that happens inside the entire facility.
Recycling wastewater starts from collection. Proper disposal of wastewater begins with the installation of appropriate wastewater collection systems, whether it comes from households and business establishments to industries, factories, and manufacturing plants.
Transporting wastewater must be leak proof in order not to destroy surrounding environment.
Once wastewater enters the facility, one of the first processes is to neutralize the foul smell. Next, large, solid wastes are separated before it goes to the main treatment facility. This is to prevent any unnecessary accident, which may cause mechanical problems in the future.
They then transport solid wastes to a nearby landfill for proper disposal.
Primary and Secondary Treatment
The main treatment starts with the process of separating macrobiotic waste from the water. Solid wastes, or sludge, are separated and collected after the process of sedimentation tank. The water will then be poured into a second container to undergo aerobic biological treatment.
This will further separate the remaining sludge from the water.
The third and final treatment is with a special apparatus and equipment that can remove up to 99 percent of wastewater impurities, making it the water closer to drinking quality. Finally, the treated water undergoes transfer to another tank where a mixture of chlorine (Cl) and sodium hypochlorite (NaClO) awaits.
Water treatment usually takes at least 20-25 minutes before released to the local waterways distribution.
