It’s not a secret, that with the rising of population, water consumption and increased production capacities the quantity of wastewater also increases constantly. The efforts to purify water are escalating, and new technologies are being developed as a solution. The leading technology out of all the modern and ecofriendly treatment technologies available today is biological purification.. However, only a few people know what steps to take to achieve maximum cleaning productivity. Read the article for details!

The efficiency of wastewater treatment can be increased!

The microorganisms that digest organic substances in wastewater has the most significant role in biological purification. Yet their reproduction and the effectiveness of purification isn’t constant. The temperature of the wastewater has a major impact on their performance.

According to the experts, it is worth to do for covering the surface of the purifying basins to prevent cleaning problems caused by inadequate temperatures.

The need for a cover layer is justified not only to reach the ideal temperature of thesewage but also to keep it on the same achieved and maintained. With a cover layer the microorganisms will be more productive and it will also bring significant cost savings.

There is only one question left: what to cover the the wastewater basin with? ?

Balls can help microorganisms to work!

Cover balls are perfect for covering the sewage basins, as they help to maintain the ideal temperature of the purifying pools by forming a continuous insulating layer on the surface.

Their use in winter time can significantly reduce the risk of freeze and also can provide an ideal temperature for microorganisms, as the thermal insulation effect of the balls slows down the cooling process. In summer, thanks to the insulation layer, the temperature of the sewage can hardly rise above 25°C.

For some treatment technologies theheating of wastewater during colder periods is unavoidable. In these cases, the use of outdoor cover balls can save up to 75% heating costs, as the floating layer of balls provides insulation ending up with less energy loss.

Let the facts and figures speak!

In recent years we have had several projects where our partners have aimed to reduce the heating costs of wastewater basins.

One of them is a company from the food industry in Hungary. They bought our water-filled Bird Ball™ in two instalments, so they were convinced about the effectiveness of the solution. The main goal was to cover four pools in total, two of which were covered with balls in the first round, while the other two were left uncovered. After months of testing, the effectiveness of the ball cover was proven, so there was no question of covering the other two pools.

In another project in Belgium, Bird Ball™ has also worked for the heated -pools of cleaning plant, as the period of heating needed has shortened considerably.

The project cost of cover balls - in projects where the goal is heating cost save up - the ROI is ideally within a year. This is very advantageous as the balls are offered with a 10-year guarantee - but it is important to note that their lifetime is much more than that! . So a quick return on investment and long-lasting cost saving is guaranteed with cover balls.

What is a cover ball?

The cover ball is a hollow high quality plastic ball that can be used to create a continuous cover layer on the surface of liquids. Depending on the amount of balls placed on a given surface, they can cover up 91% of the surface in a regular shape, self-arranging next to each other. This cover layer separates and isolates the open surface of the liquid from its surroundings, i.e. it significantly reduces the effect of the liquid on the environment and vice versa. In English, several names are used for these balls, often referred to as ‘shade ball’, ‘cover ball’, ‘armor ball’, ‘barrier ball’, or ‘bird ball’. We, as a proud European Manufacturer, call them cover ball and Bird Ball™.



How does it work? What can it be used for?

The cover balls have countless benefits, so it can be used in many diverse areas. Those advantages usually help our partners to achieve their goals for cost-saving, more efficient water management, safer work environment, environment and nature protection. Thus, the Bird Ball™ is an excellent solution for reducing evaporation, preserving water quality, preventing algae formation, keeping birds away, camouflaging the water surface, thermal insulation, reducing heating costs, reducing the release of toxic gases and vapors, reducing unpleasant odors, covering hazardous materials and many more, where cost savings or other beneficial effects can be achieved as a result of use.
