As the worldwide consumption of water goes up, the amount of wastewater produced also rises and global pollution increases. Only the most economically advanced countries have sufficient wastewater treatment systems in place, meaning that the majority of water used worldwide is released back into the environment untreated. This not only has adverse effects on the environment and human health but also exacerbates the global water scarcity problem.
If a company can connect to the sewage system for the disposal of industrial waste water, its own waste water treatment is quickly regarded as an unnecessary and unprofitable investment. However, if one takes on the necessary expertise to calculate the cost, in many cases the opposite turns out to be true.
Have you ever wondered why water drops have that circular form instead of, for example, a squared one? The answer is simple, circular shape allows molecules to hold the liquid together by occupying minimum surface area, resulting into spherical drops, as we already know.
We are all aware that water is our planet’s most valuable resource. Without enough of it, the human race would cease to exist. Which is why recent research predicting that there won’t be enough water to meet global demands by 2040 is deeply concerning. However, although current freshwater levels are depleting while the global population continues to grow, the looming crisis is not one that cannot be averted.
Many companies have their own plant for the treatment of their sanitary or industrial waste water. This cannot simply be discharged, but must undergo a number of purification steps so that it can be discharged in accordance with the applicable discharge standards, such as chemical oxygen demand, nitrogen, phosphorus, metals, …
