How is Ozone used for Pharmaceutical Residual?
Ozone is the best solution for water treatment. But did you know that it is also the best option for wastewater treatment? Specially when it comes to pharmaceutical residual, which can be harmful. It is also extremely efficient to sanitize labs and utensils, in the pharmacy industry.
So how can ozone be effective in pharmaceutical residual wastewater treatment process and to keep everything disinfected? Keep reading and you’ll find your answer!
Pharmaceutical residues in wastewater present major environmental problems, as substances such as antibiotics (eg. amoxicillin and ciprofloxacin), beta-blockers and drugs such as morphine and codeine, which, due to their complex chemical structures, difficult and often impossible in wastewater treatment systems.
These substances will have adverse effects on fish, plants and entire ecosystems, and accumulate over time due to their non-biodegradable characteristics.
Dissolved ozone is used as a sanitizing agent throughout the pharmaceutical industry.
Among the alternatives available for water sanitation, ozone being a potent oxidizing agent that effectively breaks down chemical bonds in complex molecules, it is recognized as one of the best options for disinfecting biopharmaceutical water systems and is an efficient method to remove pharmaceuticals in wastewater.
Ozone has been used in different applications and extensively studied for more than 150 years, especially in water treatment, including the wastewater treatment process.
How does it work?
Ozone is used as an alternative to heat sanitizing with hot water and steam or chemical disinfection using chlorine, chlorides, peroxides and other chemicals. It is one of the strongest commercially available oxidizers, with a disinfectant strength 3,000 times greater than chlorine due to its high eV potential. Ozone is ideal to treat pharmaceutical residual.
Ozone kills bacteria, viruses, yeasts, fungi and other microbes as a function of time, susceptibility of target organisms (action), ozone concentration and water temperature, efficiently and safely.
Ozone is safe and economical because it can be generated reliably on site as needed, avoiding the handling and costs associated with transportation and storage of oxidants. It is generated at room temperature and is soluble in water at room temperature, increasing the ease of operation.
Ozonized water leaves no chemical residues, unlike other chemical sanitizing procedures, and ambient water returns to oxygen naturally. Therefore, it does not need to be washed like the sanitized water chemically.
Ozone is a viable and accepted technological option for water sanitation and one of the most effective technologies against biofilm mitigation.
In pharmaceutical & medical industry it is very essential to keep all of the process area, tanks, equipment, furniture in highly disinfected conditions, this is one of the most critical for all process & quality purposes and can very easily be achieved using ozone surface sanitation.
Washing and rinsing with highly dissolved ozone can quickly disinfect with no residual by-product to be further treated. Ozone gives extreme disinfection without the use of hot water or steam. Operation time is greatly reduced with confidence of process.
- Preparation of pharmaceuticals, where it is used to sever carbon-carbon bonds;
- Disinfect water instead of chlorine;
- Disinfect and bleach clothes in factories (uniforms, cloths, …);
- CIP (Clean In Place);
- Deodorize air and objects;
- Kill bacteria on contact surfaces;
- Kill microorganisms in air and water sources;
- Act as an antichlor bleach based on chlorine;
- Ozone has been proven to molecularly break down dozens of widely used pharmaceticals such as Paracetamol, Codein, Propofol and Diclophenac;
- Destroys active micropollutants commonly founded in wastewater effluents such as Antihypertensives (Hydrochlorothiazide or Metoprolol), Diuretics (Furosemide) and Sedatives (Oxazepam and Carbamazepine);
- Water-intensive industries can make effective use of dissolved ozone as a substitute for chemical sanitizers, such as peracetic acid, hypochlorite, or heat;
- Chemically attacks contaminants in the water (iron, arsenic, hydrogen sulfide, nitrites and aggregate organic compounds as “colour”);
- Eradicate waterborne parasites, such as Giardia lamblia and Cryptosporidium, in surface water treatment plants;
- Disinfect the cooling towers and control legionella with reduced consumption of chemicals, water leakage and increased performance;
- Provide a flocculation aid (agglomeration of molecules, which aid in filtration, where iron and arsenic are removed);
- Manufacture of chemical compounds by chemical synthesis;
- And much more.
Safe and reliable sterilization agent;
Eliminates pharmaceutical residues from the production process wastewater;
Saves money by eliminating the on-going chemical costs;
No chemical transportation/storage – produced onsite;
Quicker sanitation: typical cycles are reduced up to 75%;
No harmful residuals that need to be removed after ozonization – ozone decomposes to oxygen;
Ozone has a powerful antimicrobial action.
