However, through our patented backwash system, we have successfully unified this piping into a single system.<br>This innovation also greatly improves ease of maintenance and on-site workability.<\/p>\n<\/section>\n\n\n\n<section class=\"l-section wp-block-bhw-wp-blocks-wrapper l-wrapper\">\n<h2 class=\"wp-block-heading c-heading _h2\" id=\"Specifications\">Specifications<\/h2>\n\n\n\n<figure class=\"wp-block-flexible-table-block-table is-scroll-on-mobile is-style-stripes\"><table class=\"has-fixed-layout\"><tbody><tr><th colspan=\"2\" style=\"text-align:center\">Model<\/th><th style=\"text-align:center\">Johkaou<br>-5<\/th><th style=\"text-align:center\">Johkaou<br>-7<\/th><th style=\"text-align:center\">Johkaou<br>-10<\/th><\/tr><tr><td colspan=\"2\" style=\"text-align:center\">Number of Users for Design<\/td><td style=\"text-align:center\">5<\/td><td style=\"text-align:center\">7<\/td><td style=\"text-align:center\">10<\/td><\/tr><tr><td colspan=\"2\" style=\"text-align:center\">Average daily wastewater inflow (\u33a5\/day)<\/td><td style=\"text-align:center\">1.0<\/td><td style=\"text-align:center\">1.4<\/td><td style=\"text-align:center\">2.0<\/td><\/tr><tr><td rowspan=\"7\" style=\"text-align:center\">Capacity<br>(\u33a5)<\/td><td style=\"text-align:center\">Solid-liquid separation chamber<\/td><td style=\"text-align:center\">0.751<\/td><td style=\"text-align:center\">1.055<\/td><td style=\"text-align:center\">1.508<\/td><\/tr><tr><td style=\"text-align:center\">Anaerobic filter bed chamber<\/td><td style=\"text-align:center\">0.750<\/td><td style=\"text-align:center\">1.052<\/td><td style=\"text-align:center\">1.511<\/td><\/tr><tr><td style=\"text-align:center\">Carrier flow chamber<\/td><td style=\"text-align:center\">0.378<\/td><td style=\"text-align:center\">0.526<\/td><td style=\"text-align:center\">0.767<\/td><\/tr><tr><td style=\"text-align:center\">Biofiltration chamber<\/td><td style=\"text-align:center\">0.127<\/td><td style=\"text-align:center\">0.178<\/td><td style=\"text-align:center\">0.252<\/td><\/tr><tr><td style=\"text-align:center\">Treated water chamber<\/td><td style=\"text-align:center\">0.084<\/td><td style=\"text-align:center\">0.118<\/td><td style=\"text-align:center\">0.167<\/td><\/tr><tr><td style=\"text-align:center\">Disinfection chamber<\/td><td colspan=\"2\" style=\"text-align:center\">0.015<\/td><td style=\"text-align:center\">0.021<\/td><\/tr><tr><td style=\"text-align:center\">Total capacity<\/td><td style=\"text-align:center\">2.105<\/td><td style=\"text-align:center\">2.944<\/td><td style=\"text-align:center\">4.266<\/td><\/tr><tr><td rowspan=\"5\" style=\"text-align:center\">Dimensions<br>(\u339c)<\/td><td style=\"text-align:center\">Overall length (L)<\/td><td style=\"text-align:center\">1,900<\/td><td style=\"text-align:center\">2,580<\/td><td style=\"text-align:center\">2,830<\/td><\/tr><tr><td style=\"text-align:center\">Overall width (W)<\/td><td colspan=\"2\" style=\"text-align:center\">1,130<\/td><td style=\"text-align:center\">1,480<\/td><\/tr><tr><td style=\"text-align:center\">Overall height (H)<\/td><td colspan=\"3\" style=\"text-align:center\">1,600<\/td><\/tr><tr><td style=\"text-align:center\">Inflow pipe base (A)<\/td><td colspan=\"3\" style=\"text-align:center\">260<\/td><\/tr><tr><td style=\"text-align:center\">Outflow pipe base (B)<\/td><td colspan=\"3\" style=\"text-align:center\">300<\/td><\/tr><tr><td colspan=\"2\" style=\"text-align:center\">Manhole diameter (mm) &amp;
