After the processes, before the discharge, the BOD5 of treated water will be reduced at least by 20% and all the suspended solids by 50%;<\/li>\n<li><strong>Secondary treatment<\/strong>: the wastewater treatment through a process that leads to the biological treatment with secondary sedimentation, or through another process in which the requirements of the third-party of this act of the table n. 1 of the attachment n. 5 are respected;<\/li>\n<\/ul>\n<p>Once understood what a treatment plant is and by how many phases is made up, we need to identify the <strong><em><u>number of users<\/u><\/em><\/strong> that will use it.<\/p>\n<p>In the civil treatment field we talk about <strong>Population Equivalent<\/strong> <strong>(P.E.).<\/strong><\/p>\n<p>This is a word used for a specific usage level in terms of uniformity and comparability with the civil users. It is a conventional concept based on an average intake of a typical user equal to 60 g\/BOD5 per inhabitant (D.Lgs. 152\/2006 art. 74), but extremely useful because it allows to easily compare various usage levels that can also be disparate, by expressing every single user with its load of \u201cPopulation Equivalent\u201d.<\/p>\n<p>Finally, we need to <strong><em><u>identify the receptor body<\/u><\/em><\/strong> in which deliver the treated waste water. The D.Lgs. 152\/06 (art. 103 -104-105-106-107) classifies the final discharges as follows:<\/p>\n<ul>\n<li>Discharges on the ground<\/li>\n<li>Underground discharges<\/li>\n<li>Discharges in surface water<\/li>\n<li>Discharges in sewerages<\/li>\n<\/ul>\n<p>As a result, depending on the discharge final disposal, various <strong>system solutions<\/strong> can be provided. These solutions, as treatment performance, reach the limit concentrations shown in Table 3 (discharge in surface water and in public sewerage) and in Table 4 (discharge in the ground) of the Unique Environmental Paper D. lgs. 152\/06 (Part III \u2013 Attachment 5).<\/p>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-37488\" src=\"https:\/\/tubi.net\/wp-content\/uploads\/2021\/09\/Civil-wastewater-treatment-plants-sizing-X.png\" alt=\"\" width=\"1055\" height=\"333\" srcset=\"https:\/\/tubi.net\/wp-content\/uploads\/2021\/09\/Civil-wastewater-treatment-plants-sizing-X-200x63.png 200w, https:\/\/tubi.net\/wp-content\/uploads\/2021\/09\/Civil-wastewater-treatment-plants-sizing-X-300x95.png 300w, https:\/\/tubi.net\/wp-content\/uploads\/2021\/09\/Civil-wastewater-treatment-plants-sizing-X-400x126.png 400w, https:\/\/tubi.net\/wp-content\/uploads\/2021\/09\/Civil-wastewater-treatment-plants-sizing-X-600x189.png 600w, https:\/\/tubi.net\/wp-content\/uploads\/2021\/09\/Civil-wastewater-treatment-plants-sizing-X-768x242.png 768w, https:\/\/tubi.net\/wp-content\/uploads\/2021\/09\/Civil-wastewater-treatment-plants-sizing-X-800x253.png 800w, https:\/\/tubi.net\/wp-content\/uploads\/2021\/09\/Civil-wastewater-treatment-plants-sizing-X-1024x323.png 1024w, https:\/\/tubi.net\/wp-content\/uploads\/2021\/09\/Civil-wastewater-treatment-plants-sizing-X.png 1055w\" sizes=\"(max-width: 1055px) 100vw, 1055px\" \/><\/p>\n<p>The images down below show a summary of the most commonly used standard plants depending on the type of final discharge.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-37485\" src=\"https:\/\/tubi.net\/wp-content\/uploads\/2021\/09\/Civil-wastewater-treatment-plants-sizing-XX.png\" alt=\"\" width=\"1053\" height=\"649\" srcset=\"https:\/\/tubi.net\/wp-content\/uploads\/2021\/09\/Civil-wastewater-treatment-plants-sizing-XX-200x123.png 200w, https:\/\/tubi.net\/wp-content\/uploads\/2021\/09\/Civil-wastewater-treatment-plants-sizing-XX-300x185.png 300w, https:\/\/tubi.net\/wp-content\/uploads\/2021\/09\/Civil-wastewater-treatment-plants-sizing-XX-400x247.png 400w, https:\/\/tubi.net\/wp-content\/uploads\/2021\/09\/Civil-wastewater-treatment-plants-sizing-XX-600x370.png 600w, https:\/\/tubi.net\/wp-content\/uploads\/2021\/09\/Civil-wastewater-treatment-plants-sizing-XX-768x473.png 768w, https:\/\/tubi.net\/wp-content\/uploads\/2021\/09\/Civil-wastewater-treatment-plants-sizing-XX-800x493.png 800w, https:\/\/tubi.net\/wp-content\/uploads\/2021\/09\/Civil-wastewater-treatment-plants-sizing-XX-1024x631.png 1024w, https:\/\/tubi.net\/wp-content\/uploads\/2021\/09\/Civil-wastewater-treatment-plants-sizing-XX.png 1053w\" sizes=\"(max-width: 1053px) 100vw, 1053px\" \/><\/p>\n<p>P.N.: the plant sequences shown in the image are purely indicative.
