Wastewater and effluent from drug, medicine, cosmetic, biotech, and medical device manufacture are generated all over the world at production locations and product research and development centres. When compared to disposal of this hazardous waste, Netsol industrial wastewater treatment technologies offer purification of all pharmaceutical, medical, and cosmetic wastewaters, resulting in significant cost savings.
Process water is utilised in various medication and drug formulations, cosmetic product manufacturing, and equipment cleaning and disinfection, resulting in significant water consumption and, as a result, substantial effluent volumes to be treated.
With our modular industrial wastewater treatment solutions, we can achieve environmental compliance with any discharge regulations.
Is wastewater treatment in pharmaceutical industry a challenge?
Pharmaceutical, medical, and cosmetic wastewaters are generated during the production of a wide range of pharmaceuticals, supplements, and medicines, as well as the cleaning and processing processes that accompany them.
Thus the wastewater flow and load can become extremely complex and varied. As a result, pharmaceutical wastewater is difficult to treat using traditional methods. Because of the nature of the pollutants found in pharmaceutical and medical wastewater, factories are often required to adhere to stringent restrictions. Due to a lack of understanding about possible process technologies in many facilities, wastewater is removed and disposed offsite.
APIs and other medical residues, even at minuscule quantities in treated wastewater, are wreaking havoc on aquatic ecosystems and human health. Because traditional wastewater treatment techniques aren't designed to breakdown persistent chemicals, the toxins end up in the environment.
Technologies for wastewater in pharmaceutical industry
For pharma and cosmetic applications, specialised solutions with process guarantees and minimal operation costs are designed. Physical, chemical, biological, and oxidative process phases are all included in custom solutions. Even for persistent, inert, and difficult-to-degrade chemicals, these combined procedures enable for full pollutant removal and destruction.
Pharmaceutical wastewater treatment systems are modular and expandable, and often include a combination of process technologies:
Dissolved air flotation (DAF)
Fats, oils, and grease (FOG), suspended solids (TSS), biological oxygen demand (BOD), food/animal production/processing wastes, industrial wastes, hydrocarbon oils/emulsions, and a variety of other contaminants are all removed using dissolved air flotation systems.
Electrical advanced oxidation
Advanced oxidation processes (AOP) are a type of chemical treatment that oxidises organic molecules in wastewater that are difficult to handle biologically and converts them to simple final products.
pH modification during wastewater treatment necessitates residency or contact time for the pH to vary as needed. pH, being a chemical component of wastewater, has a direct impact on the treatment ability of wastewater, regardless of whether it is treated physically, chemically, or biologically. It is vital to treatment because it is such an important component of the wastewater's constitution.
Chemical treatment [flocculation, coagulation]
Coagulation-flocculation is a chemical water treatment procedure used before sedimentation and filtration (e.g. quick sand filtration) to improve a treatment process' ability to remove particles.
The techniques by which microorganisms break down and eliminate nutritious components from wastewater are referred to as biological treatment. While dissolved oxygen is required for the decomposition of carbon compounds and the production of ammonia (nitrification), it is not required for the degradation of nitrate (denitrification). Biological cleaning, which occurs naturally in streams and rivers, is ultimately the technical solution.
Reverse Osmosis and Ultrafiltration
During the ultrafiltration (UF) process, water is forced through a semipermeable membrane. Water and low-molecular-weight solutes pass through to the permeate side of the membrane, while suspended particles and high-molecular-weight solutes remain on the retentate side.
Water softening and Ion exchange
Ion exchange is a water treatment technology that involves exchanging one or more undesired ionic contaminants with a non-objectionable or less objectionable ionic material.
The adsorption of pollutants onto the surface of a filter is the basis of activated carbon filtration, which is a widely utilised technology. This approach is effective for removing some organics (unwanted taste and odours, micropollutants), chlorine, fluoride, and radon from drinking water or wastewater.
Chemical and biological pollutants can be found in pharmaceutical, medical, and cosmetics wastewater. In general, this wastewater contains dissolved solids, pharmaceuticals from manufacturing processes, micropollutants, and solvents and chemicals, among other things. These wastewaters might be complex in composition, containing chemicals that are difficult to breakdown using traditional processing methods.
