Filtration is a critical part of many commercial and industrial processes. The reality in many industries is that pumping water from locations such as a refinery, food, and beverage, textile application requires water prefiltration because of the high levels of suspended solids in these applications. Along with water technology, there are typically several filtrations in these applications to ensure that the treated water meets reuse standards. Additionally, water treatment filtration ensures mitigated operating costs on downstream polishing of water treatment systems.
What are the harmful effects of water contaminants?
A majority of contaminants are found in regular drinking water. When it comes to pollutants, it is extensive and describes anything found in tap water that isn’t considered water molecules. Some examples of contaminants are bacteria, salmonella, and iron. It can be traced to tap water. For example, sulphur in water can sometimes have a laxative effect on some people who consume it. Chlorine in water has been linked to the premature aging of the skin and asthma, and many others. But in tiny doses, these contaminants are harmless.
However, there is no reason to take a chance. By installing a water purification system that utilises current water technology, an establishment is taking a critical step in enhancing tap water safety and quality.
The following are a few examples of advanced treatment processes that require prior filtration for optimum operation.
Finer filtration includes membrane filters such as reverse osmosis filters as well as nanofiltration. The majority of filtration systems operate on a gradient. It begins with a rougher and coarser filtration and moves along in steps to the finest level required. This process of coarse filtration is engineered to keep the filters going for as long as possible. It keeps the filtration going until it needs cleaning or replacement. If there is a presence of clay or sand in the water solution, it is filtered through a tunnel filter, or it might clog up quite swiftly. However, suppose the water solution is filtered through a system that catches all the sun first and then catches the silt and clay. In that case, the fine filters will be able to operate the smaller particles optimally.
Disinfection processes involve the treatment of tiny pathogens via oxidation. But interference due to solid particulate matter mitigates the treatment efficiency of these systems.
For example, UV disinfection utilises ultraviolet radiation to eradicate bacteria. The light’s wavelength travels from the light source via the fluid to the targeted pathogens. But if suspended particles are within the solution, they will physically block the light waves from triggering pollutants needed to be appropriately disinfected.
Like disinfection, advanced oxidation helps to dissolve compounds. It utilises hydroxyl radicals which are produced via a combination of ozone and hydrogen peroxide. Contaminants that are unfiltered mitigate the effectiveness of UV light, as has been described previously. However, other pollutants such as hydroxyl scavengers will also reduce the process’s efficiency if they are present in high concentrations. Because of this, proper prefiltration, along with several other treatments, can keep these radicals out entirely.
It is critical to have clean water and utilise a filtration system to ensure that the tiniest pathogens and sediments are eradicated from water solutions. Filtration systems make sure the tap water is treated regularly so there will be zero chemicals and bacteria. It is critical to understand the process of filtration and the necessity of prefiltration to ensure optimum results.
