A detailed analysis of the effluent is carried out, based on which <strong>treatment systems are designed<\/strong>, equipment is selected, and appropriate water treatment methods are defined.<\/p>\n\n\n\n<p>Company specialists install, service, and repair <strong>mechanical wastewater treatment units<\/strong> and provide professional \u043a\u043e\u043d\u0441\u0443\u043b\u044c\u0442\u0430\u0446\u0456\u0457 on equipment selection. A quality guarantee is provided for the full range of services.<\/p>\n\n\n\n<p><strong>Mechanical Wastewater Treatment Methods<\/strong><\/p>\n\n\n\n<p>During mechanical wastewater treatment, <strong>solid and suspended particles<\/strong> are removed from the medium. This is a <strong>preliminary stage<\/strong> of wastewater preparation prior to discharge or reuse, during which the effluent is prepared for subsequent <strong>biological or physicochemical treatment<\/strong>.<\/p>\n\n\n\n<p>The main mechanical methods for wastewater treatment at industrial enterprises and sewerage systems include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Screening<\/strong>. The primary stage of water treatment, during which wastewater passes through screens that retain fibers and insoluble impurities.<\/li>\n\n\n\n<li><strong>Sedimentation<\/strong> \u2014 removal of suspended solids from wastewater. The method is based on gravitational forces, causing contaminants to settle at the bottom of sedimentation tanks.<\/li>\n\n\n\n<li><strong>Filtration<\/strong> \u2014 separation of suspended solids by passing wastewater through fine-mesh screens or porous media such as anthracite, quartz sand, gravel, or similar materials.<\/li>\n\n\n\n<li><strong>Centrifugation in hydrocyclones<\/strong> \u2014 separation of solid particles within a rotating flow of the medium.<\/li>\n<\/ul>\n\n\n\n<p>After mechanical water treatment, <strong>sludge dewatering<\/strong> is performed. This process also consists of several stages:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Preparatory stage<\/strong>. Preliminary dewatering of wastewater sludge is carried out using filter presses through conditioning by organic flocculation \u2014 aggregation of sludge using flocculants. This increases the sludge\u2019s ability to release water.<\/li>\n\n\n\n<li><strong>Main stage<\/strong>. The partially dewatered sludge layer obtained after the previous stage is covered with quicklime and converted into granules. During the reaction, the temperature of the solidified particle layer rises to <strong>+80 \u00b0C<\/strong>, promoting both dewatering and disinfection of the sludge.<\/li>\n\n\n\n<li><strong>Final stage<\/strong> \u2014 complete dewatering of wastewater sludge by mechanical \u0432\u043e\u0437\u0434\u0435\u0439\u0441\u0442\u0432\u0438\u0435 on the solidified particle layer using centrifugal force, vacuum, or pressure.<\/li>\n<\/ul>\n\n\n\n<p><strong>Facilities for Mechanical Wastewater Treatment<\/strong><\/p>\n\n\n\n<p>The main structural elements of facilities for mechanical wastewater treatment include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>screens;<\/li>\n\n\n\n<li>grit chambers;<\/li>\n\n\n\n<li>sedimentation tanks.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image is-resized\"><img decoding=\"async\" src=\"https:\/\/ziko.com.ua\/wp-content\/uploads\/2023\/08\/738b892b-6b8d-4a96-b67b-f174bd3f0110.jpg\" alt=\"\"\/><\/figure>\n\n\n\n<p>Using <strong>screens for wastewater treatment<\/strong>, large floating contaminants are removed from the flow. Screens may be <strong>movable or stationary<\/strong> and are installed at an angle of <strong>65\u201375\u00b0 to the horizontal<\/strong>. During operation, wastewater screens require <strong>regular cleaning<\/strong> to remove accumulated debris.<\/p>\n\n\n\n<p><strong>Grit chambers<\/strong> are designed to remove <strong>mineral contaminants<\/strong> from wastewater. The flow velocity through grit chambers must be adjusted so that <strong>only heavy mineral particles settle<\/strong>, while organic matter and finer particles are carried away by the water flow. Depending on the direction of wastewater movement, grit chambers are classified into three types:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>horizontal;<\/li>\n\n\n\n<li>vertical;<\/li>\n\n\n\n<li><strong>slot-type<\/strong> \u2014 wastewater flows along the bottom of a special channel, where sand and impurities are separated.<\/li>\n<\/ul>\n\n\n\n<p><strong>Sedimentation tanks (grease traps)<\/strong> are reservoirs used for mechanical wastewater treatment in which contaminants are separated from a medium moving <strong>vertically or horizontally<\/strong>. Impurities may <strong>settle at the bottom<\/strong> of the tank or <strong>float to the water surface<\/strong>, depending on their physical properties.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"900\" height=\"500\" src=\"https:\/\/ziko.com.ua\/wp-content\/uploads\/2023\/12\/Mekhanichne-ochyshchennia-stokiv2.png\" alt=\"\" class=\"wp-image-7441\" srcset=\"https:\/\/ziko.com.ua\/wp-content\/uploads\/2023\/12\/Mekhanichne-ochyshchennia-stokiv2.png 900w, https:\/\/ziko.com.ua\/wp-content\/uploads\/2023\/12\/Mekhanichne-ochyshchennia-stokiv2-600x333.png 600w, https:\/\/ziko.com.ua\/wp-content\/uploads\/2023\/12\/Mekhanichne-ochyshchennia-stokiv2-300x167.png 300w, https:\/\/ziko.com.ua\/wp-content\/uploads\/2023\/12\/Mekhanichne-ochyshchennia-stokiv2-768x427.png 768w, https:\/\/ziko.com.ua\/wp-content\/uploads\/2023\/12\/Mekhanichne-ochyshchennia-stokiv2-280x156.png 280w\" sizes=\"auto, (max-width: 900px) 100vw, 900px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Advantages of Mechanical Wastewater Treatment<\/strong><\/h2>\n\n\n\n<p>Various mechanical wastewater treatment methods make it possible to remove the following from the effluent:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>large foreign objects;<\/li>\n\n\n\n<li>fats and oils floating on the wastewater surface;<\/li>\n\n\n\n<li>sand and other mineral particles.<\/li>\n<\/ul>\n\n\n\n<p>A properly selected mechanical wastewater treatment method ensures <strong>effective preparation of the effluent<\/strong> for subsequent <strong>physical, chemical, or biological treatment<\/strong>.<\/p>\n\n\n\n<p>The company offers <strong>cost-effective ready-made solutions<\/strong> for mechanical treatment of wastewater from industrial enterprises and sewerage systems.
