sewage treatment plants

Water is the same everywhere. However, the kind of waste generated varies with the industry that produces it. Each wastewater type has characteristics that make it and its treatment unique. Here are some wastewater types that STPs and industrial effluent treatment plants handle day in and day out to contribute to environment conservation and safety.

Types of Wastewater

From municipal sewage to industrial wastewater, let’s look at the different types of wastewater.

  • Municipal Sewage

As the name implies, municipal sewage is generated from commercial buildings, households, etc. The sewage generated from showers, toilets, sinks from houses, hospitals, restaurants, etc., is termed municipal sewage. Although almost only water, domestic sewage does contain a minuscule amount of dissolved and suspended solids with microbes that can prove harmful to humans and hence requires efficient treatment.

  • Storm Sewage

Again, as the name suggests, storm sewage is the water that gushes into the city sewers after precipitation. This type of sewage contains dirt, twigs, and debris. Additionally, it includes a massive amount of organic material that the water picks up while flowing in.

  • Industrial Sewage

This is the broadest sewage type of all and comprises effluent generated from various types of industries and factories. Treating industrial sewage demands specialized industrial effluent treatment plants capable of treating chemical effluents. Let’s look at a few of the industrial sewage types.

  • Textile

Processes like dyeing, bleaching, waterproofing, flameproofing, etc., generate high volumes of chemical waste. The wastewater generated often contains a high BOD and elements like chromium, grease, oil, sulfides, etc. Additionally, the use of various dyes like mordant dyes, acid dyes, pigment dyes, etc., also contributes to a tremendous amount of wastewater that contains oil, grease, heavy metals, and phenols.

  • Pharmaceutical

Pharmaceutical sewage is often considered more complex due to its heavy chemical content. The waste contains a range of hormones, volatile organic compounds, antibiotics, etc., the accidental discharge of which can prove harmful to the human body. Besides, the drug byproducts in pharmaceutical waste have a high degree of chemical oxygen demand and biological oxygen demand.

  • Petroleum Refining and Petrochemical Manufacturing

The waste generated by these industries have a heavy concentration of metals like cadmium, arsenic, lead, mercury, chromium, etc. The wastewater generated through the various manufacturing processes has a high BOD and contaminants like phenols, ammonia, sulfides, etc.

  • Paper Manufacturing

The waste that these manufacturing units generate contains high BOD and concentrations of suspended solids. Additionally, with bleaching as part of the manufacturing process, the effluent will include elements like dioxins, furans, chloroform, etc., and usually a high COD.
