The filtering media plays one of the most crucial roles in the treatment of liquids. Whether it was regarding bringing up to potable levels or bringing down to borderline non-toxic disposable levels, the ideal performance of the filtering media would always affect the overall efficiency. There comes a time when they need to be replaced due to several reasons. But the question is, how can you know when? Let us find out.

When the filtering media size seemed to have diminished/expanded

Consistent utilization as a medium to catch debris subjects them to gently wear off with time; sand and gravel can be identified as best examples. But there are some other purification media whose size tends to increase as they’re being used for the treatment process. This happens due to the accumulation of all sorts of dirt and bacteria growth. Although both of these situations can be mildly managed, there always would be a point where they no longer can sever as filtering media. If you don’t replace them timely, there’s a good chance of your machinery being damaged as well.

When the dissolved oxygen content of the outflow is dropping

It is a common procedure to check the DO or the dissolved oxygen content of the treated liquid in comparison to that of the inflow. If the DO content is showing a gradual decrease, it means that the treatment is being done well. Lower DO content indicates the lack of dissolved oxygen context because if it worked according to the expectations, it would be otherwise. As long as the rest of the system is working in the required manner, the replacement of the purification media can be identified as a cost-effective solution.

When the characteristics of the intake are changing drastically

Choosing the purification media of a treatment facility heavily depends on the nature of the intake as well. Due to the abnormalities of nature during the past few years in Brisbane, the changes in the environment, in general, can have a significant impact on the aquatic aspects. Thus, expecting your old filtering media of the treatment facility to adhere accordingly is just not the answer to the problem; instead, you should replace them.

When it’s time for a full restoration

Although the typical purification material tends to last for 8-10 years of time, there can be other factors that can require full restoration of the facility. On such an occasion, it is never a bad choice to replace the media for good. This would increase the efficiency of the refurbished treatment machinery to a greater extent. After all, what’s the point of a full restoration if you have to stick to the old material?

Conclusion

The importance of the role of the purification media in liquid treatment will never diminish. As long as you understand it well, there’s no doubt that you’ll make timely decisions. Now that you know what to look out for, the process is going to be even easier.
