What is Ph Level and Its Significance in Water Filtration?

August 17, 2017

Chemical textbooks describe pH levels as an acidity or alkalinity measuring tool. The pH range starts at 0 and climbs as high as 14. At this highest level, the measured substance is said to be strongly alkaline. By the same convention, acids exist below pH 7. Halfway up this numerical scale, lays chemical neutrality. This chemistry lesson is interesting, but what does it have to do with water filtration technology?

Water Filtration: The Importance of pH Levels

As a general rule, drinking water is maintained at pH 7. The human body enjoys this chemically neutral feature. Likewise, the pipes and seals in a water system last longer if the medium flowing in those channels isn't corrosive. In order to maintain that chemical ideal, we install water filtration assemblies. They basically keep the water equipment-safe and suitable for all plants and swimmers.

Hitting the pH7 Sweet Spot

First of all, what happens if the water isn't balanced? Unhealthy fish swim in their aquarium, garden features bloom with algae, and people leave their swimming pools with burning eyes. A water conditioning system restores the pH balance. Then, because of this water-neutral feature, the pool no longer causes nasty red eyes or dry skin. Similarly, fish and plant life are protected from the corrosive influences of an unbalanced water supply. Curiously, though, we haven't taken a look at what's causing these issues. Could it be the chlorine?

The Water Conditioning Balancing Act

Keep your pool equipment happy by balancing the pH level. That's not as easy a task as it sounds, not when the water needs constant conditioning. Chlorine additives keep the pool clean. The sanitation process removes bacteria, acts as a powerful algaecide, and generally scours the water clean of contaminants. Unfortunately, the pH level rises along its logarithmic scale when these conditioners are added. A high pH clogs filters and inhibits the above cleansing features. A low pH value, on the other hand, corrodes pool grout. It also damages the pipe seals. A balanced pool or pond, a water supply that sits between 7.0 and 7.4, is one that doesn't harm its biological inhabitants.

Chlorinated water loads the liquid with a PPM (Parts Per Million) supply of chlorine until the pH orbits around the pH 7.0 mark. Other chemical compounds, including sodium bisulphate, lower and raise the level so that it can be maintained at a near chemically neutral point on the 0 to 14 logarithmic scale. Held here, the pool equipment, tile grouting, and your own health are safely balanced. That's a principle also works in aquariums and ponds.
