Question

Write about waste water treatment in 150 words.​

Answer 1

Explanation:

Wastewater treatment is a process used to remove contaminants from wastewater and convert it into an effluent that can be returned to the water cycle. Once returned to the water cycle, the effluent creates an acceptable impact on the environment or is reused for various purposes (called water reclamation).[1] The treatment process takes place in a wastewater treatment plant. There are several kinds of wastewater which are treated at the appropriate type of wastewater treatment plant. For domestic wastewater (also called municipal wastewater or sewage), the treatment plant is called a sewage treatment plant. For industrial wastewater, treatment either takes place in a separate industrial wastewater treatment plant, or in a sewage treatment plant (usually after some form of pre-treatment). Further types of wastewater treatment plants include agricultural wastewater treatment plants and leachate treatment plants.

Processes commonly used include phase separation (such as sedimentation), biological and chemical processes (such as oxidation) or polishing. The main by-product from wastewater treatment plants is a type of sludge which is usually treated in the same or another wastewater treatment plant.[2]: Ch.14  Biogas can be another by-product if anaerobic treatment processes are used. Some wastewater may be highly treated and reused as reclaimed water. The main purpose of wastewater treatment is for the treated wastewater to be able to be disposed or reused safely. However, before it is treated, the options for disposal or reuse must be considered so the correct treatment process is used on the wastewater.

The term "wastewater treatment" is in the literature often used to mean "sewage treatment".[3] Strictly speaking, wastewater treatment is broader than sewage treatment.

Answer 2

Treatment of waste water is the best way of reducing water pollution and keeping the water animals safe from toxic waste.

Explanation:

• Water treatment is one of the best ways of reducing water pollution mainly around industrial areas.
• Water treatment is mainly done using chemicals or industrial plants that remove waste in steps.

• The solid waste is removed at first. Then the water without a solid component is sent to purifiers where other waste material is removed from the water.
• Then the water can be let out safely into the nearby water bodies.
