Guarding Against Evaporation and Algae Growth in Water Storage
In the realm of water management, the significance of a robust water storage system cannot be overstated. However, a vital aspect often overlooked is the role of an appropriate cover. Approximately 85% of NPI water tanks are thoughtfully complemented with covers that come in various forms, such as ENPI airfloat covers, tensioned anti-algae covers, and galvanized steel roofs. The wisdom of this practice becomes evident when we consider the consequences of leaving water uncovered.
The reasons for employing covers are compelling. Without a protective shield in place, water faces the perils of significant evaporation, which can deplete precious resources. Moreover, unchecked algae growth can compromise water quality and lead to complications in irrigation systems.
Among the array of covers available, one of the most sought-after options from NPI is the tensioned anti-algae cover. Crafted from 210-gram woven polypropylene and featuring a reinforced edge with stainless steel eyelets, this cover is designed for effectiveness. It is secured externally to the water tank or a supporting structure using specialized hooks and nylon cords. The primary purpose of this cover is to inhibit algae growth, serving as a guardian that also shields water from contamination by small debris and minimizes evaporation. Its unique woven design allows water to permeate through, ensuring a delicate balance.
The tensioned anti-algae covers are best suited for tanks with diameters of up to approximately 9 meters. For larger tanks, a reinforcement ring at the upper edge, in conjunction with a center pole, is recommended for optimal performance.
As autumn approaches, it’s essential to consider the role of the anti-algae cover. This season heralds a reduction in sunlight and a drop in temperature, leading to decreased algae growth. However, it also brings heightened wind activity, which can deposit leaves and debris on the cover, potentially compromising its permeability during rainfall. The accumulated weight could exert undue pressure on both the cover and the tank walls, particularly in the face of snowfall. As a result, there’s an increased risk of damage to the cover and the water tank.
With the onset of autumn, it’s prudent to remove and inspect the anti-algae cover. This involves checking the fabric for tears and ensuring that the cords and hooks are in good condition. During the winter months, the cover should be stored, safeguarded against damage and the elements, and readied for reinstallation in spring. This routine maintenance helps preserve the integrity of the cover and, by extension, the quality and quantity of stored water, securing a valuable resource for the future.
