At new Era Total our irrigation services are not limited to irrigation installation we also are experienced in water testing and treatment to EPA approved levels. Our teams can provide you with a water quality test onsite and provide the correct level of treatment with a flocculant.

So what is Flocking?

Clearing up muddy or cloudy water: a guide to floccing

Growing plants and tubestock in Australia could require a lot of water, especially in drier and arid areas. Getting the right amount of nutrients to the soil through watering can be challenging if there is silt, clay, sand, or other organic solids in your water.

In some cases, these solid contaminants are suspended throughout your water, which is known as a colloid. In the best-case scenario, the contaminants settle at the bottom or rise to the top. The more solids in this suspended state, the poorer the water quality.

If your water supply or dam is looking cloudy or muddy, it’s a sure sign of a high suspended solid concentration. This can lead to less efficient use of water and higher water costs and wastage. One way to get more from your irrigation is to use flocculant. What is flocculant and how does it help?

Explaining flocculant and the flocculation process

Flocculation is the process of treating suspended organic particles with a specialised solution, known as a clarifying agent, to help drag them to the bottom (or float to the top) and clear the water. Flocculation is a common process in water treatment, water decontamination, beer brewing, and even cheese making.

This binds the organic particles together by attracting them with an opposing electron charge, increasing (or decreasing) its mass. This is known as sedimentation. Sedimentation is one method of flocculation; the alternatives being flocculation brings solids to the surface (known as creaming) or have them clump together for easier filtration.

How to assess your water supply – does it need flocculation?

Though muddy or cloudy water may hint at a high soil particle concentration, it’s important to do a small test first. Using a small sample of water, you will be able to see if the particles naturally settle on their own, or if they respond well to flocculant or “floc.” We apply floc and adjust according to the results of the sample.

This determines what type of flocculant you need and the correct dosage. Testing beforehand can also help figure out how to prevent colloids from forming in the future.

It’s important to test beforehand to ensure the right balance of pH and salinity is maintained for your plants or livestock.

The advantages to flocculation

Flocculation helps improve the quality of your water and helps you use less water for the same result. For those in fish farming, it also increases the amount of nutrients your fish can take in without contamination.
