WASTE WATER TREATMENT PLANT IN BANGLADESH
Man-made wastewater is the byproduct of human activities. It can contain a variety of contaminants such as industrial chemicals, pharmaceuticals, and radioactive substances. Wastewater treatment plants (WWTP) are designed to neutralize these contaminants in order to prevent them from entering the water cycle. They help remove unwanted and harmful substances from our water supply and maintain a healthy aquatic environment.
What are the types of wastewater plants systems?
Wastewater treatment plants are designed to treat sewage, process and purify the water. The type of wastewater treatment plant depends on the nature of wastewater.
The three main types of wastewater treatment plants:
Primary wastewater plant: Primary wastewater plants are those which convert the wastewater from different sources into a usable form. These plants use the process of biological and chemical treatment to separate the waste materials. The treated water is then reused for other purposes such as irrigation or municipal water supplies.
Secondary wastewater plant: A secondary wastewater plant is used to treat wastewater by removing the dissolved and suspended solids, and then reusing them. Secondary wastewater plants have several advantages over primary treatment systems. They are more efficient in handling the sewage, and the treated effluent can be reused in agriculture or industrial processes.
Tertiary wastewater plant: Tertiary wastewater plant is the wastewater treatment plant that treats the wastewater from the industries, agricultural fields, and municipal drainage systems. A tertiary wastewater plant is also known as a tertiary treatment plant or a tertiary treatment plant. The primary aim of the tertiary wastewater plant is to treat and degrade all harmful pollutants such as chemical compounds, microbiological species, and micro-organisms. This will reduce the levels of these contaminants in the treated water so that they are safe for discharge into waterways or air. The tertiary treatment plant also has the ability to remove odorant materials, colorants, and other nutrients from wastewater using activated sludge processes before final disposal. The tertiary treatment plant should also be capable of removing excess nutrients and sludge from the wastewater before it is discharged into waterways or air. This will help to improve water quality in these areas and reduce the amount of pollution that ends up in rivers, lakes, and oceans.
