In the bustling heart of India’s healthcare system, hospitals stand as pillars of hope and healing, tirelessly serving communities day and night. Yet, behind the scenes of life-saving surgeries and patient care lies a less visible but critical challenge, that is managing the wastewater generated by these facilities.
Hospitals produce vast amounts of wastewater daily, laden with pathogens, pharmaceuticals, and chemicals that, if left untreated, can pose severe risks to public health and the environment. At SKF Elixer, we understand these challenges and have dedicated ourselves to crafting advanced sewage treatment plants (STPs) and sewage management solutions tailored for Indian hospitals, ensuring safety, compliance, and sustainability.
This blog explores why hospital wastewater management is a pressing need, how specialized STPs address the unique demands of medical facilities, and the innovative technologies that make SKF Elixer a trusted partner for healthcare institutions across India.
Whether you’re a hospital administrator, a facility manager, or an environmental enthusiast, this guide will shed light on the critical role of STPs in safeguarding communities and ecosystems.
The Unique Challenge of Hospital Wastewater
Hospitals in India, from small clinics in rural towns to sprawling urban medical complexes, generate an estimated 50–400 litres of wastewater per bed daily. This wastewater is far from ordinary. Unlike domestic sewage, hospital wastewater is a complex mix of contaminants, including microbial pathogens, pharmaceutical residues, disinfectants, and heavy metals.
For instance, laboratories produce wastewater with chemical residues, while patient care areas contribute biological waste. If released untreated into rivers, lakes, or municipal sewers, this effluent can contaminate water bodies, spread waterborne diseases like cholera or typhoid, and even contribute to the rise of antibiotic-resistant bacteria.
Consider a 100-bed hospital in a city like Bengaluru or Mangaluru. On average, it generates 20,000–40,000 litres of wastewater daily. Without proper treatment, this could pollute local water sources, endangering communities and ecosystems. The presence of pharmaceutical contaminants, such as unmetabolized antibiotics, poses a particularly insidious threat, fostering drug-resistant microbes that can spread through water systems. This makes hospital waste management not just an operational necessity but a public health imperative.
Why Hospitals Need Specialized STP Systems
The complexity of hospital wastewater demands more than a standard sewage treatment plant. Conventional municipal systems are designed for household waste and often lack the capacity to handle the hazardous pollutants found in medical effluent.
This is where specialized hospital STP solutions come into play. These systems tackle the unique composition of hospital wastewater head-on and ensure the treated water meets stringent environmental standards. They discharge or reuse the water only after it passes all required quality checks. In addition, they help hospitals reduce pollution, stay compliant, and manage water sustainably.
At SKF Elixer, our STPs are designed with the specific needs of Indian hospitals in mind. We recognize that healthcare facilities vary widely in size and scope, from compact 20-bed clinics in Tier-2 cities to 500-bed super-specialty hospitals in metropolitan areas. Our solutions are scalable, efficient, and compliant with the rigorous norms set by the Central Pollution Control Board (CPCB) and State Pollution Control Boards (SPCBs).
For example, CPCB guidelines mandate that treated water must have a Biochemical Oxygen Demand (BOD) below 30 mg/L and Chemical Oxygen Demand (COD) below 250 mg/L, ensuring minimal environmental impact.
Beyond compliance, STPs offer practical benefits. Treated water can be reused for non-potable purposes like irrigation, flushing toilets, or cooling systems, reducing a hospital’s freshwater consumption by up to 30–50%. For a 200-bed hospital, this could translate to savings of ₹1–2 lakh annually on water bills, making STPs a cost-effective investment in sustainability.
Turning Hazardous Waste into Safe Water
A well-designed sewage management plant follows a multi-stage process to transform hazardous hospital wastewater into safe, compliant effluent. At SKF Elixer, our STPs are built to handle the unique wastewater challenges in medical facilities with precision and reliability. Here’s how the process works:
1. Preliminary Treatment
The journey begins with removing large debris, such as bandages, syringes, or paper waste, which could clog or damage equipment. Bar screens and grit chambers filter out solids, while equalization tanks stabilize the flow and pollutant load to prevent system overload. This step is crucial for protecting downstream processes and ensuring consistent treatment.
2. Primary Treatment
In this stage, wastewater enters sedimentation tanks where heavier solids settle as primary sludge, and lighter materials like oils and greases are skimmed off. This reduces suspended solids by 50–60%, preparing the water for biological treatment. For a 50 KLD (kilolitres per day) plant, this stage might handle 25–30 kilograms of sludge daily, which is then processed separately.
3. Secondary Treatment
The heart of the STP lies in its biological treatment process, where microorganisms degrade organic matter and pathogens in aeration tanks. SKF Elixer’s Anaerobic-Aerobic Baffled Reactor (AABR) technology also known as Attached Growth Bioreactor, is specifically designed for hospital wastewater, offering exceptional efficiency in treating complex pollutants. AABR utilizes fixed biofilm carriers that foster robust microbial growth, enabling the system to break down organic matter, pathogens, and pharmaceutical residues effectively. This technology achieves up to 90% reduction in organic pollutants, significantly lowering BOD and COD levels, while consuming 20–30% less energy than conventional systems, making it ideal for Indian hospitals seeking cost-effective and sustainable solutions.
4. Tertiary Treatment
The final polish ensures the water is safe for discharge or reuse. Advanced disinfection methods, such as UV light, ozone, or chlorination, eliminate remaining pathogens and pharmaceutical residues to produce high-quality water suitable for gardening or flushing. This stage ensures compliance with CPCB norms, with fecal coliform levels below 100 MPN/100 mL.5.
Sludge Treatment Process
The sludge generated during primary and secondary treatment contains concentrated pollutants and requires careful handling. SKF Elixer’s STPs incorporate sludge dewatering systems, such as filter presses or centrifuges, to reduce sludge volume to 100–200 kilograms per day for a medium-sized hospital.
Hospitals can safely dispose of treated sludge or, if it’s non-hazardous, repurpose it as fertilizer. This approach not only supports resource recovery but also aligns with India’s push for sustainable sewage management.

The Bigger Picture: Health, Environment, and Sustainability
Investing in a hospital Sewage management is about more than meeting regulations, it’s about protecting communities and building a sustainable future. Untreated wastewater can devastate ecosystems, contaminate drinking water, and increase the incidence of waterborne diseases.
Hospitals have a responsibility to lead by example. By treating wastewater effectively, healthcare facilities can prevent environmental damage and demonstrate their commitment to public health.
Moreover, STPs align with India’s push for sustainability. The National Green Tribunal (NGT) and CPCB encourage water reuse, with guidelines mandating dual plumbing for non-potable applications. Hospitals adopting SKF Elixer’s STPs can reduce their environmental footprint, lower water bills, and enhance their reputation as eco-conscious institutions. For instance, a hospital reusing 20,000 litres of treated water daily can save ₹75,000–₹1 lakh annually. While earning accolades for environmental stewardship.
