Sewage Treatment plant for hospitals

December 13, 2022by newebay020

In the present era, wastewater/sewage treatment is required in many industries. When it comes to hospitals, they use a lot of water daily and generate a lot of wastewater.

 

Since, hospital sewage and wastewater contain a variety of potentially dangerous elements, it poses numerous threats to people’s health and the environment by contaminating surface and ground water. Consequently, hospital sewage treatment is absolutely necessary.

 

Sewage treatment plant and its requirement in hospitals

 

According to standard definitions, wastewater is made up of physical, chemical, and biological waste. Hospital sewage is wastewater that is produced in substantially greater amounts from all of the hospital’s departments, including emergency and first aid, operating rooms, drug treatment, intensive care units, radiography, chemistry and biology labs, canteen and laundry operations, etc.

 

Before it is directly released into the environment, hospital sewage treatment facilities’ main goal is to treat influent, or untreated wastewater, produced by the healthcare and hospital industries. Hospital wastewater may be harmful to the environment and to people’s health. Therefore, it is essential that all hospitals manage their wastewater properly.

 

Characteristics of hospital sewage

 

Hospital wastewater includes the following:

 

  • Bacterial and viral pathogens that are dangerous to humans.
  • Pharmaceuticals and their by-products.
  • Radioactive elements.
  • Risky substances and metals.
  • Drug traces.

 

Process used in a hospital sewage treatment facility

 

A sequence of processes is taken while creating a compact or packaged sewage treatment plant for hospitals. The following is a list of traditional procedures used to clean the influent of pollutants.

 

  1. Initial Phase or Pre-treatment

 

In the majority of sewage treatment plants (STP), the preliminary treatment procedure is crucial as a first step. Through bar screens, it removes huge material from the influent, including sticks, rags, and other large objects as well as heavy inorganic solids. The removal of these materials guards against damage to the plant’s machinery.

 

Additionally, grit is the term for the inorganic sediment that is eliminated using a grit chamber.

 

  1. Primary stage

 

The primary treatment stage is the next stage in the sewage treatment process. During this stage, particles and greases are physically separated from wastewater. In order to allow solid particles to settle and lighter particles to float to the top, water is now pumped into primary filters or clarifiers for a short period of time.

 

About 60–70% of the settled material, also known as primary sludge or primary effluent, is made up of solids. The effluent has now moved on to the next stage of treatment.

 

  1. Secondary Treatment Stage

 

This biological treatment stage eliminates dissolved inorganic elements from the wastewater, which are present in soluble and colloidal form. The colloidal and dissolved organic matter is converted in this case by microorganisms.

 

Now, the primary tank’s partially treated wastewater flows into the aeration tank, where air is supplied by an air blower to give bacteria oxygen. When wastewater enters the secondary clarifier, solids settle to the bottom and form secondary sludge.

 

Part of this sludge is recycled for use in the activated sludge process, while the remaining portion is combined with primary sludge and sent to the sludge digestion tank, for disposal. The inorganic solids are removed at this stage by around 90%.

 

  1. Tertiary treatment

 

The final stage of the majority of STPs is known as the tertiary or advanced treatment stage. The organic materials and suspended particles that were not removed during secondary treatment, are removed during this stage.

 

In this stage a technique, known as, Disinfection is used to get rid of the pathogenic bacteria that were left over after biological treatment. Several disinfection agents can be utilized based on wastewater quality.

Chlorine, UV radiation, ozone, and other chemical or physical disinfectants are used to achieve this. Wastewater that has been disinfected can now be disposed of or used again.

 

Conclusion

 

The dangerous elements in the sewage pose a risk to both human health and the environment, if the water is not cleaned properly. Therefore, sewage treatment facilities in hospitals are always required, to minimize negative environmental effects.
