How To Choose A Side Stream Filter

August 24, 2020, by Tower Water

You may have heard of inline filtration and one of its alternatives, side stream filtration. Choosing which filtration option is best for each individual business or building, such as a side stream filter, depends on the unique circumstances at play, but despite being less common than inline filtration, side stream filtration has its own set of positives.

Remember that water filtration is critical not only for the environment but also for the efficacy and longevity of any systems you own that process water. Contaminants in the water contribute to the overall decay of a system through corrosion, weakening of valves and instruments, and even the growth of microbial colonies that can cause harm to both people and pipes. Making responsible decisions about water treatment can benefit your business and everyone who spends time there; an experienced water treatment professional can guide you on whether side stream filtration is the right option for you and provide you with actionable steps.

What Is A Side Stream Filter?

Side stream filtration is a process by which the water in a system is cleaned—but not all at once. Unlike inline filtration, which runs constant filtration on all water, side stream filtration cleans the water in portions (but continuously). This can be effective depending on what the system is trying to achieve; for example, the force of the water flow and the most common contaminants will influence how a side stream filtration option functions, as higher pressure will require more sturdy components.

In addition, whether the side stream system includes traditional or automatic screen filters, microfilters, or high-efficiency media filtration all depends on the unique situation of the building. This is why it is important to have your system evaluated by a professional.

Open Loop Systems

In an open-loop system, process fluid enters the cooling station and flows over the warm areas. At this point, the water that is being used to cool the heated sections is exposed to open air, which means that it can become polluted with any contaminants present in the environment or atmosphere.

In an open-loop side stream filtration system, the filter often has a lot of work to do, because contaminants enter the water during the cooling cycle. Side stream filters will be cleaning portions of water continuously and will need to effectively capture these contaminants in order to ensure the system functions well.

Closed Loop Systems

Closed-loop systems, in contrast, are not exposed to environmental contaminants, because the water that passes over the heated elements to cool them is contained within a closed “circuit” that prevents outside contact. This does not, however, mean that contaminants cannot enter the water.

Closed-loop systems are still vulnerable to contaminants and solids as a result of corrosion, leaking, new construction, or the introduction of new additions to a system. Over time, these contaminants can cause further erosion as well as wear and tear on metals, seals, valves, and any monitoring instruments present in the system. Pollutants can also contribute to microbiological growth and reduce the effectiveness of water treatment chemicals.

Closed-loop systems can benefit from a variety of filtration systems depending on the unique circumstances, whether using side stream filtration or not. However, because the number of contaminants tends to be less in closed-loop systems that are properly maintained to avoid corrosion and other wear and tear, side stream filtration that cleans portions of water continuously can perform the task efficiently and without the need for complex filtration options.

Call the Commercial Filtration Experts For You Side Stream Filter

A water treatment pro can provide you with an overview of your water system, including areas that need improvement so that you can make informed decisions about the filtration option that is best for you—including potential side stream filtration to improve efficiency.
