How wastewater treatment companies are saving the environment
Wastewater is disastrous for aquatic biodiversity. Its affects are extremely adverse in the following ways:
• The decaying organic matter uses up loads of dissolved oxygen from a lake making it difficult for fish and other aquatic biota to survive
• Eutrophication, or over-fertilization can happen through excess of Phosphorus and Nitrogen, which can be toxic to aquatic organisms, promote unnecessary growth, reduce available oxygen and lead to a decline in certain species
• Chlorine compounds and inorganic chloramines are fatal for aquatic invertebrates, algae and fish
• Bacteria can pollute beaches and contaminate shellfish
• Metals, like mercury, lead, cadmium, chromium and arsenic are catastrophic for animals
All this raises the importance of wastewater treatment companies, and the utilities are established to make sure:
Fisheries are clean and healthy
Sustainable wildlife habitats can exist on shoreline, beaches and marshes which include fish, other aquatic animals and even migratory birds which rest and feed near water bodies.
Clean water is made available for recreational purposes so that activities such as swimming, fishing, boating etc., can be carried out in a healthy manner.
Healthy water is aplenty. Waterborne diseases are really scary because everyone shares water to spread the virus or bacteria quickly. Wastewater treatment ensures healthy water is provided to everyone.
Wastewater treatment is breaking down all the harmful chemicals added to the water that leaves people’s homes or industry. Mostly, wastewater is 99% water and the solid or dissolved waste is less than one percent and just that amount can cause all the trouble.
The treatment is generally up to three levels to properly clean water – primary, secondary and tertiary. Wastewater management is done differently at different utilities management services in UAE, because it entirely depends on how the water is being reused.
Following is a standard process used for wastewater treatment:
Primary treatment
This is the first step and its purpose is to remove solid particles. The water is simply passed through fine screens which filter out the solids such as paper, plastic etc. Heavier waste like sand sinks to the bottom of the tank from where it is removed.
Following this, wastewater is passed through primary sedimentation tanks, and then solids settle at the bottom and oils or grease floats to the top, from where it is removed.
Secondary treatment
When the major and visible waste is chunked out, the wastewater enters secondary treatment where it is flown into tanks with good bacteria. This breaks down the solid waste and cleans out the nutrients from water.
Following that, wastewater flows into clarifiers so that heavy particles settle down and can be collected.
Tertiary treatment
When primary and secondary treatments do their bit, time comes for tertiary treatment. In this, wastewater is given a final dual media filtration process and chlorine or ultraviolet light (UV) is used to kill of all remaining microorganisms.
What we really want to achieve from wastewater treatment is to remove the maximum amount of suspended solids before the water that remains, called effluent, is flown back into the environment. Removing solid material is extremely pertinent because otherwise it will use up oxygen for its decay and lessen availability for aquatic life.
