The water in the pharmaceutical industry has a direct relationship with manufacturing, product, quality, and safety. It is used in a variety of manufacturing and support functions.
The entire product portfolio is dependent on water for manufacturing.
Every pharma product has its criticality for human life and must be treated with most quality & safe procedures. For example, parenteral product’s method of administration bypasses the usual safety system of the human body. Due to these reasons and many more, water in the pharmaceutical industry must be of pharma grade standards
Water Treatment plants are critical equipment in the pharmaceutical industry to ensure water quality. Raw water undergoes chemical and physical transformations that make it fit for critical pharmaceutical applications. The plant consists of multiple stages that have specific functions in removing various types of impurities and contaminants.
Filters and instruments are integral to water treatment, among many other components and parts. Filters provide an essential method of clearing out impurities of all sizes and levels. Instrumentation offers insight into the process, equipment, and water conditions at all stages of treatment. This, in turn, is used to monitor different aspects of treatment operations for process improvement, quality, safety, and compliance purposes.
Filters in the treatment Plants
Filters in Water Treatment Plants are used to filter out impurities present in the water. Since water contains different types of impurities, a single filter type can be ineffective in removing impurities .
Filters are strategically installed in different stages of the treatment plant. As the water flows through these stages and filters, the filter filters out the relevant impurities and contaminants. The process is repeated throughout the plant until the purified water emerges from the output section.
Some common uses in water treatment plants are described below.
Multimedia Filter
They are used in the pre-filter section of a water treatment plant to filter out large particles. The section is made up of layers of different media, such as sand, gravel, and anthracite. The advantage of using different media is that it can filter out variable-sized particles in a single stage.
These media are arranged in layers. Water enters from the top, where large particles are removed, while small or fine particles are filtered out at the bottom.
Activated Carbon Filter
Activated Carbon filters remove organic components and chlorine from the water. They are deployed in the pre-treatment stage of the treatment plant. They are also capable of removing odor and taste from the water and improving turbidity.
Activated Carbon filters consist of a purpose-made carbon material made from carbon-containing materials such as coal or coconut husk. The carbon is burnt at a high temperature with reduced oxygen concentration. Depending on the application and/or process, various forms, such as granular or powder, can be used to fit the filtration process.
They are used to filter in initial stages before the water is fed to higher filtration technologies such as Reverse Osmosis and EDI, to increase their performance and life.
Microfiltration
Microfiltration is a type of membrane filtration that is deployed after the pre-filtration stage. It is made of polymer materials and has good mechanical and chemical strength. However, it is only effective for particles from 0.1μm to 10μm.
The water to be filtered is forcefully passed through the microfiltration. Particles greater than the pore sizes are blocked, while particles smaller than the pore sizes pass through the filter. They come in different categories, including pipe-shaped and flat-sheet-shaped.
Ultrafiltration
Ultrafiltration is also a membrane-based filter suitable for small particle sizes from 0.01μm to 0.1μm. It can block suspended solids, bacteria, and viruses. The water to be purified is passed through the filter under pressure.
Ultrafiltration in pharmaceutical water treatment is used to filter out large particles and bacteria that can threaten the Reverse Osmosis sect...
