The purpose of sewage treatment plants remains uniform across diverse sectors, although the challenges may vary and be specific to each site. Several factors need to be evaluated and examined to ensure that Akruthi Enviro Solution aligns with your requirements, timeframe, and budget. These factors encompass wastewater type, fluctuating flow rates, consumption patterns, and the land at your disposal in pharmaceutical facilities.
We understand wastewater and make an effort to grasp the unique needs and context of your specific business before proposing, strategizing, and implementing a customized on-site wastewater solution.
What is sewage treatment plant?
A sewage treatment plant is a specialized facility created to manage and process sewage, with the primary goal of purifying it by removing contaminants and impurities. The treatment procedure usually incorporates a combination of physical, biological, and chemical techniques to efficiently cleanse the wastewater.The primary objective of a sewage treatment plant is to generate an effluent, or treated water, that meets safety standards for release into natural water bodies or, in certain instances, for recycling in non-potable uses such as irrigation or industrial activities. The operation of sewage treatment plants is essential for upholding public health and environmental integrity, ensuring the proper treatment of wastewater before it is discharged back into the natural environment.
Why pharmaceutical industry wastewater treatment plants are important
Pharmaceuticals perform an important role in the treatment and prevention of disease in both human and animal populations. Due to their potent design for high activity, interaction with receptors in humans and animals, or toxicity against various infectious organisms, pharmaceuticals may inadvertently pose consequences for wildlife and microorganisms in the surrounding environment. Traditional methods utilizing an activated sludge process are still commonly employed in wastewater treatment, mainly because they yield effluents that adhere to mandated quality standards (appropriate for disposal or recycling) with manageable operational and maintenance expenditures.
Pharmaceutical compounds are typically produced through batch processes, leading to the occurrence of a diverse array of substances in wastewater produced during different operations involving extensive water usage for tasks like rinsing solid cake, extraction, or equipment washing. In general, this wastewater contains:
1. A high organic matter content, a significant portion of which is readily biodegradable (alcohol, acetone, etc).
2. Organic substances that break down slowly and persistent compounds (aromatic compounds, chlorinated hydrocarbons, etc).
3. Compounds that hinder and display harmful effects (antibiotics).
4. Soaps and detergents containing surfactants.
5. However, it has been demonstrated that this type of treatment has a restricted capacity to eliminate pharmaceuticals from wastewater.
Two Different Sources
The occurrence of pharmaceutical compounds in potable water stems from two sources:
1. pharmaceutical production operations and,
2. common use of pharmaceutical compounds,
This results in their presence in urban and farm wastewaters. The wastewater generated during various stages of pharmaceutical and drug manufacturing contains a diverse array of compounds.
Different Treatment Techniques
Industry requires the reuse of water after the elimination of contaminants, whether they are pharmaceuticals or other substances. Given the scarcity of water resources, it is crucial to grasp and formulate approaches for the treatment of pharmaceutical wastewater within the context of water management.
Different treatment techniques are:
Activated sludge biological process : The activated sludge process stands out as one of the most adaptable and extensively employed biological treatment methods.Even though the treatment process remains effective in diverse climates, but its capacity may decrease in colder conditions. Activated sludge methods are commonly employed subsequent to primary treatment and, in certain instances, succeeded by a concluding refinement phase within an intricate treatment regimen.
Anaerobic Digestion Process : The benefits of using anaerobic digestion are numerous, it can manage high organic loads, result in reduced sludge production, and entail lower operating costs. Alternative treatment options include mechanical steam compression vacuum evaporators and advanced oxidation processes.
Moving Bed Biofilm Reactor Process: Moving Bed Biofilm Reactor processes automatically sustain an optimal level of efficient biofilm, making the treatment cost-effective and low-maintenance. In contrast to activated sludge systems, MBBR systems eliminate the need for sludge recycling. The incorporation of MBBR as a retrofit enhances the capacity of the existing plant.
The analysis of wastewater from different segments of the active pharmaceutical ingredients (API), bulk drugs, and related pharmaceutical industries, which utilize substantial water volumes, is conducted. The proposed strategies aim to efficiently recover valuable compounds, and the examination of highly diluted but hazardous wastewaters is addressed. There is no single technology capable of completely removing pharmaceuticals from wastewater. Utilizing traditional treatment methods alongside membrane reactors and advanced post-treatment techniques to develop a hybrid wastewater treatment technology seems to be the most favourable choice.
