Fish farming, or aquaculture, refers to raising fish in controlled environments, such as tanks or ponds. This method of fish production has become increasingly popular in recent years due to the increasing global demand for fish and fish products.
Fish farming has many advantages over traditional fishing, such as: reducing overfishing, minimizing the impact on wild fish populations, and providing a more reliable source of fish. However, it also comes with several challenges, including the spread of diseases, unhealthy growth due to feeding practices, and water quality issues.
UV radiation effectively disinfects water, especially in the 200-280 nm wavelength range. However, it is still essential to ensure the system’s reliability and accuracy, which is where validation comes into play. The confirmation refers to verifying the system’s performance, providing it operates as planned and delivers reliable treatment.
Regulatory authorities frequently demand validation; some nations have laws regarding this. The goal is to protect public health by ensuring water treatment systems work to the necessary standards. Routine confirmation may also be required to maintain the system’s functionality and avoid potential flaws or issues.
Validation is a valuable tool for both the user and the producer. The manufacturer can monitor the system’s performance, identify areas for improvement, and make any necessary corrections to ensure that the system operates according to its intended design and performance requirements.
At the same time, validation provides the user with an unbiased evaluation of the system’s performance, allowing for better-informed decision-making and maintenance planning.
Most UV purification research has primarily focused on evaluating the efficacy of antimicrobial properties, neglecting the uniformity of UV radiation distribution in the process flow.
However, several factors, such as the lamp’s lifespan, the purity of the quartz sleeve, the position and type of UV sensor, the flow rate, and the UV transmittance, all influence how UV radiation has an antimicrobial impact.
Designers and customers can only predict the efficiency of a specific UV purification system in each process water system with an approach that standardizes the link between UV antimicrobial activity, individual UV systems, and all highly dynamic UV intensity factors. Several UV purification models have appeared, each attempting to link the UV intensity data of a particular approach to its antimicrobial effectiveness.
Regulatory conventions have strict validation protocols, including parallel UV bioassays and standardized microbial reductions under controlled conditions. This process generates algorithms to create a UV dose construct for each system, which allows designers and customers to determine the expected antimicrobial activity for their specific applications and conditions.
The validation of each UV system results from a comprehensive and standardized process involving multiple labs and computational modeling executed under challenging biohazard conditions by skilled personnel.
It is critical to understand the distinction between certified and inferior UV systems, simply “lights in a pipe” or “lights in a channel,” unless shown otherwise. In the pharmaceutical and life science sectors, it is critical to demand Factory Acceptance testing and Master Validations from system component vendors, as all vital systems must go through Installation Qualification, Operational Qualification, and Process Qualification (IQ/OQ and PQ) validation. It ensures that all system capabilities have been thoroughly checked and recorded, even those not investigated or validated during the IQ/OQ/PQ process validation. UV validation with verified proven pathogen inactivation must be a criterion for UV purification systems to be allowed on the market.
Because it is impractical and costly for the designer or customer to bear this role, the market must demand unbiased, third-party UV validation utilizing generally agreed-on standard validation procedures.
UV technology stands as a valuable and proficient approach to water treatment, particularly in UV water disinfection aquaculture systems. Nonetheless, assuring the dependability and precision of the system remains of the utmost importance, underscoring the significance of validation. Regulatory bodies consistently require validation, a pivotal instrument serving users and manufacturers by delivering impartial assessments of system efficacy.
