What are the main attributes of influent wastewater?

Wastewater, also known as sewage water, is water that has been contaminated by human activity. It typically consists of water discharged from homes, industrial plants, and agricultural lands and contains both solid and liquid wastes. Contaminants in wastewater vary in levels and concentrations.

Sewage treatment plants are used to treat wastewater. But how do you go about finding the best wastewater treatment plant?

Understanding the characteristics of influent wastewater is the first step in answering this question.

Here is a quick rundown of the various characteristics of wastewater so that you can identify the type of sewage water treatment plants you require and select a water treatment plant that effectively addresses your issues.

Water has three distinct characteristics: Physical, chemical, and biological.

1-Physical characteristics:

Color, odor, temperature, and turbidity are some of the physical characteristics of wastewater. Freshwater is typically brown in color, but as it is exposed to the environment, it gradually turns yellow before eventually turning black. There will also be a lot of turbidity in the wastewater. This is due to the presence of suspended solids in wastewater, which causes it to appear cloudy.In terms of odor, sewage water has a strong odor. Because of the increased biological activity in wastewater, the temperature has risen. Understanding this aspect is critical because a thorough understanding of the physical components can assist you in selecting the best sewage water treatment plant.

Wastewater's physical properties:

· Color - Fresh sewage is normally brown and yellowish in color, but it darkens over time to become black in color.

· Odor – Sewage-contaminated wastewater typically has a strong odor.

· Temperature - As biological activity increases, the temperature of wastewater rises.

· Turbidity - Due to the presence of suspended solids in wastewater, wastewater has a higher turbidity, or cloudiness.

2-Chemical characteristics:

Some of the components that determine the chemical characteristics of wastewater are nitrogen, phosphorus, chlorides, sulphates, pH, heavy metals, and so on. A thorough analysis of the physical and chemical characteristics is performed in order to identify the best sewage treatment plant in India. Using the results, you can select the wastewater treatment plant that best meets your needs.

Wastewater's chemical properties:

Wastewater contains a variety of chemicals in various forms, as listed below

· COD (Chemical Oxygen Demand) - COD is a measure of organic materials in wastewater based on the amount of oxygen required to oxidize the organic materials.

· TOC (Total Organic Carbon) - TOC is a measure of the carbon content of organic materials.

· Organic nitrogen is the amount of nitrogen found in organic compounds.

· Organic phosphorous (in protein) and inorganic phosphorous (phosphates, PO^4- )

· The chlorides (Cl)

· Sulfates (SO₄^-2)

· Heavy metals

3-Biological characteristics:

The biological aspects of wastewater include biochemical oxygen demand (BOD), nitrogenous oxygen demand (NOD), and the presence and concentration of microbial life. Bacteria, protozoa, fungi, viruses, algae, rotifers, and nematodes make up the microbial life in wastewater.

Biological wastewater characteristics:

Microbial life in wastewater - The following microbes can be found in wastewater:

1.Protozoa Bacteria

2.Viruses of Fungi

3.Rotifers of Algae

4.Nematodes
