India is facing a water crisis, with demand estimated to surpass availability by nearly twice by 2030. This is a serious worry, which begs the question, "How can we construct strong water infrastructure in India?"
Handful individuals know that wastewater can be transformed into reusable water with high accuracy. Although, water is a renewable resource, evaporation and rain take a long time to remove impurities. Fortunately, current wastewater treatment systems can offer safe and reusable water, making the procedure much faster.
What are the effective UV solutions for ETP and wastewater reuse?
Water is used in practically every industry, including pharmaceuticals, chemicals, vehicles, textiles, food processing, automotive, textile, electrical and electronics, and hospitality, to name a few.
Chemical, physical, organic, and biological elements contaminate the water and render it unsafe, for direct disposal into the environment. An effluent treatment plant (ETP) is a system that removes the aforementioned effluents from industrial wastewater, and cleans it so that it can be safely released or reused.
ETPs are also frequently employed in ZLD (Zero Liquid Discharge) plants, which reduce the need for fresh water in industry, while simultaneously protecting the natural environment.
Disinfection of Wastewater
After primary, secondary, and sometimes tertiary wastewater treatment, wastewater disinfection occurs. It is usually the last stage in the process of removing biological pollutants from treated water.
Role of disinfection technique
Disinfection reduces the amount of germs and bacteria in the water to acceptable levels, preventing the spread of waterborne diseases.Because, wastewater contains significant amounts of microbiological pollution, it must be cleaned before it is released into the environment.
Although, current membrane-based wastewater treatment techniques such as MBRs lower this burden to some amount, the most popular methods for disinfecting wastewater are ultraviolet radiation (UV) and chlorine. The issue with chlorine is that it does not give adequate protection against chlorine-resistant pathogens, including Cryptosporidium, Guardia, and viruses.
Furthermore, it causes plant and building corrosion, which limits effective plant life and makes it highly expensive in the long run. It also changes the pH of water, rendering it unfit for reuse, like irrigation.
Ultraviolet Disinfection: What are the benefits of UV disinfection?
Acknowledging the potential negative effects of chlorination, governments worldwide are advocating the use of alternate disinfection technologies.
UV (ultraviolet disinfection) has long been recognized as an effective disinfectant. The knowledge base and installed base of UV disinfection plants have grown exponentially, during the previous two decades.
UV disinfection of effluent is non-toxic and non-hazardous, and it can be monitored in real time using properly constructed UV intensity sensors and monitors. Because, suspended debris, oily compounds, and humic acids absorb UV-C radiation in wastewater, these systems are designed for peak flow rate and lowest UVT (UV transmission) of wastewater.
Furthermore, the UV reactor hydraulic design, UV lamp kinds, and other elements all have an impact, on the reactor's performance.
Why use UV Systems for effluent disinfection or Industrial Wastewater Treatment?
UV water disinfection technology has grown in popularity around the world. The main reason for this is its low cost, and UV is favoured as an alternative to traditional chlorination, not only for wastewater disinfection but also for process water disinfection, among other things.
