The recent abnormal heat wave and drought this summer has dramatically highlighted the importance of treating water as a valuable resource.<\/strong> In this context, plants for the purification of first rain water emerge as a key element to avoid waste, and promote responsible management of water resources.<\/strong><\/p>\n

First rain water plants: what they are and how they work<\/h2>\n

First rain water treatment plants are rainwater collection system<\/strong><\/a> . These, once purified, are sent back to a collection basin from which they can then find a new use.<\/strong><\/p>\n

The “first rain”<\/strong>, in fact, that is the first 5 millimeters fallen in the first 15 minutes of precipitation<\/strong> (in some regions, the “first rain” is instead identified with the first 4 mm<\/strong>), is potentially the most polluted. In fact, it collects particles<\/strong>, dirt and micro-pollutants suspended in the air, or on the places of precipitation, usually aprons and parking lots<\/strong>. The first rain water, therefore, must be specially treated to reuse it without risk in the domestic and industrial environment<\/strong>, as well as for re-immissioning in the environment.<\/p>\n

First rainfall plants<\/strong>, in short, contribute to an efficient and responsible management of water resources<\/strong> because in the first place they separate the first rain waters from the so-called second rain waters (less polluted). Then, they allow you to collect and treat them, sending them back to a suitable purification system.<\/p>\n

During precipitation, especially the most abundant, rainwater is collected in a drain with weir<\/strong>. Here, the waters of second rain, which touch the threshold of 4 or 5 millimeters, are immediately sent to the final delivery<\/strong> (except in some regions, which provide a special treatment for these). The first rainwater<\/strong>, however, is channeled into a subsequent treatment plant.<\/strong><\/p>\n

There are two types of plants<\/strong> for first rain water:<\/p>\n
