Healthcare facilities and hospitals utilise water on a daily basis for various reasons. The treatment plants consist of black water, which is highly contaminated wastewater from toxic chemicals, human waste and food residues. The plants also have grey water, which is a lowly contaminated wastewater that comes from bathing and laboratory processes. The last type of water is stormwater, which comes from the roofs of the hospital or other areas within the facility. Effluent treatment plants for hospitals are a dependable system that provides a safe, sustainable and efficient way to manage hospital effluent.

How do the effluent treatment plants in hospitals work?
Effluent treatment plants at hospitals are necessary facilities for the treatment and management of waste that is produced by various hospital activities. The wastewater may have hazardous components that include drugs, chemical compounds, heavy metals, pharmaceuticals, disinfectants and radioactive isotopes. It is mandatory for healthcare facilities to treat effluent properly following the necessary guidelines. Here are four steps that show how effluent treatment plants work.
Collection- The wastewater from the various hospital facilities, like the kitchen, patient rooms, laboratory and operating rooms, is collected with the help of pipelines. The wastewater is usually separated into different streams depending on how much it has been contaminated. It can be in the blackwater or greywater stream. The wastewater passes through bar screens before going into the collection tank. The bar screens help remove objects such as plastics, papers and rags. It also avoids clogging and damage to the mechanical equipment in the downstream process.
Primary Treatment- The wastewater enters a chamber where the water flow slows down, and the water undergoes a physical and chemical process to separate organic matter and suspended particles. This allows the heavy waste products to settle due to gravity.
Secondary Treatment- This treatment happens when the wastewater from the primary treatment stage flows into a large tank. Airblowers continuously supply oxygen to the tank, and that provides an oxygen-rich environment. This environment promotes the growth of bacteria and microorganisms. The bacteria consume the dissolved organic components and turn them into carbon dioxide, new biomass and water. While the microorganisms are processing the organic waste, they come together and start forming heavier and larger particles.
Tertiary treatment- In this stage, solids and bacteria are filtered out by water flowing through the sand and other particles. Membranes are used to block contaminants through backwashing in order to clean the water. The UV irradiation damages and kills microorganisms. Chlorine is used to kill viruses, bacteria and parasites, although dechlorination is required to get rid of harmful by-products. Using a UV (Ultraviolet) is mostly preferred because there is no chemical residue.
Conclusion
Effluent treatment plants are systems designed to meet the hospital and healthcare medical needs. If you are in need of a hospital effluent plant, you can contact NK Dairy Equipment. Ms. Himpreet Kaur and his team design effluent plants that can handle complex medical waste and maintain standards. We provide effluent plants that operate at a wide scale to disinfect wastewater found in hospitals. Our effluent plants meet the operational demand and also uphold sustainable and responsible hospital waste management.
FAQS
- What are effluent treatment plants for hospitals?
A: Effluent treatment plants for hospitals are used to treat wastewater that has contaminants like bacteria, antibiotics, heavy metals and domestic sewage.
- Why are effluent treatment plants important?
A: Effluent treatment plants are used to clean wastewater that contains chemicals and drugs so that they don’t harm the environment and the health of the public.
- Can the treated water from effluent treatment plants be reused?
A: Yes, the water from the treated effluent plants can be reused for toilet flushing and gardening. It helps reduce the freshwater demand.
