If flowing through deep layers of soil containing sand and granite will dissolve some minerals. If it penetrates through the limestone layers, it will have a high hardness. Microorganisms are rarely found in water because groundwater is located deep in the ground. Their growth is restricted in anaerobic environments.<\/p>\n<p>Feed water contains many types of dissolved minerals such as iron, magnesium, manganese, calcium, etc. These metals will accumulate over time, causing great harm to human health and damage and corrosion of storage systems. Therefore, a prerequisite of a feedwater treatment system is to remove or reduce these components. Water will be treated physicochemically, solids will be removed as sludge.<\/p>\n<p>The pH of groundwater is usually between 4 \u2013 4.5, slightly acidic. The initial groundwater pumped up is usually very clear. But after exposure to air, it will turn yellow-brown because of oxidation of iron in water:<\/p>\n<h4><span class=\"ez-toc-section\" id=\"4_Fe2_aq_O2_g_4_H_aq_%E2%86%92_4_Fe3_aq_2_H2O_l\"><\/span>4 Fe<sup>2+<\/sup> (aq) + O<sub>2<\/sub> (g) + 4 H<sup>+<\/sup> (aq) \u2192 4 Fe<sup>3+<\/sup> (aq) + 2 H<sub>2<\/sub>O (l)<span class=\"ez-toc-section-end\"><\/span><\/h4>\n<h4><span class=\"ez-toc-section\" id=\"Fe3_aq_3_H2O_l_%E2%86%92_FeOH3_s_3_H_aq\"><\/span>Fe<sup>3+<\/sup> (aq) + 3 H<sub>2<\/sub>O (l) \u2192 Fe(OH)<sub>3<\/sub> (s) + 3 H<sup>+<\/sup> (aq)<span class=\"ez-toc-section-end\"><\/span><\/h4>\n<figure id=\"attachment_3071\" aria-describedby=\"caption-attachment-3071\" style=\"width: 1800px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-3071 size-full\" src=\"https:\/\/arkvietnam.com\/wp-content\/uploads\/2022\/03\/groundwater.jpg\" alt=\"\" width=\"1800\" height=\"854\" srcset=\"https:\/\/arkvietnam.com\/wp-content\/uploads\/2022\/03\/groundwater.jpg 1800w, https:\/\/arkvietnam.com\/wp-content\/uploads\/2022\/03\/groundwater-510x242.jpg 510w, https:\/\/arkvietnam.com\/wp-content\/uploads\/2022\/03\/groundwater-300x142.jpg 300w, https:\/\/arkvietnam.com\/wp-content\/uploads\/2022\/03\/groundwater-1024x486.jpg 1024w, https:\/\/arkvietnam.com\/wp-content\/uploads\/2022\/03\/groundwater-768x364.jpg 768w, https:\/\/arkvietnam.com\/wp-content\/uploads\/2022\/03\/groundwater-1536x729.jpg 1536w, https:\/\/arkvietnam.com\/wp-content\/uploads\/2022\/03\/groundwater-18x9.jpg 18w, https:\/\/arkvietnam.com\/wp-content\/uploads\/2022\/03\/groundwater-600x285.jpg 600w\" sizes=\"auto, (max-width: 1800px) 100vw, 1800px\" \/><figcaption id=\"caption-attachment-3071\" class=\"wp-caption-text\"><em>Groundwater and surface water<\/em><\/figcaption><\/figure>\n<h2><span class=\"ez-toc-section\" id=\"Xu_ly_nuoc_cap_voi_nguon_dau_vao_la_nuoc_song\"><\/span><span style=\"font-size: 23.04px;\">Treatment of feed water with the input source being river water<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Determining the characteristics of the input water source is the first thing to do.
