Filtration <\/span>plants<\/b> are systems<\/b> specifically designed to remove <\/span>contaminants and impurities from water used<\/b> in industrial processes. Such systems are essential to ensure that the primary or process water is <\/span>of<\/b>\u00a0 suitable <\/span>quality for processing<\/b>, safe for operator health and fully in line with environmental regulations.<\/span><\/p>\n

 <\/p>\n

Blue Water Technology<\/b>\u00a0 <\/span>designs and manufactures<\/b> different types of water filtration systems to meet the water treatment needs of the most diverse industrial contexts.<\/span><\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Quartzite filtration for suspended solids<\/div>\n
\n

These <\/span>filtration plants use<\/b>\u00a0 <\/span>layers<\/b> of quartz<\/b> to remove solids suspended in the water. They are suitable for the <\/span>treatment of primary and process water in<\/span>\u00a0 various industrial sectors because they guarantee an effective removal of fine particles, low operating costs and easy maintenance.<\/span><\/p>\n<\/div>\n

Sand filtration for suspended solids<\/div>\n
\n

They are <\/span>filtration plants<\/b>\u00a0 <\/span>that<\/b> use<\/b> layers <\/span>of sand as a<\/b> filter medium to remove suspended solids from the water. This technology is widely used in waste water treatment plants, processes and even drinking water: it ensures effective removal of particles of various sizes, a reliable and proven filtration system and excellent performance with large volumes of water.<\/span><\/p>\n<\/div>\n

Active carbon filtration for adsorption of organic pollutants (COD\/BOD\/pesticides)<\/div>\n
\n

This technology uses <\/span>activated carbon<\/b> to remove from the water, through<\/b> adsorption<\/span>,<\/b> organic pollutants potentially harmful to people and the environment (COD removal, BOD removal, pesticide removal, color removal). It is used for the <\/span>treatment of drinking water and process<\/b>\u00a0 water and for the purification of water contaminated with organic substances. Its advantages include the high adsorption capacity of organic substances and volatile chemical compounds and the improvement of the overall organoleptic qualities of water.<\/span><\/p>\n<\/div>\n

Filtration by cartridge<\/div>\n
\n

These <\/span>water filtration plants use special<\/b> filter cartridges to <\/span>remove<\/b> particles and impurities from the water. They are generally indicated for low flow rates and low concentrations of suspended solids, often as <\/span>pre-filtration in reverse osmosis or ultra-filtration plants<\/b>, <\/span>and in sectors that require<\/b> high performance in the filtration process, such as in pharmaceutical industries, food and electronics. In addition to high efficiency and reliability, the advantages of this technology include easy cartridge replacement and versatility in various filtration grades.<\/span><\/p>\n<\/div>\n

Filtration with self-cleaning filters<\/div>\n
\n

These systems use <\/span>filters capable of self-cleaning<\/b>, usually by a back-washing mechanism. They are ideal for <\/span>low flow rates in the<\/b> presence of high concentrations <\/span>of<\/b> solids and ensure concrete reduction of downtime-activity, reduced need for manual maintenance, reliability and consistency in the quality of water filtration.<\/span><\/p>\n<\/div>\n

Ion-selective filtration<\/div>\n
\n

Especially when using groundwater, it is possible that elements are dissolved in it which make it unsuitable for industrial or civil use due to the presence <\/span>of heavy metals (such as<\/b>\u00a0 <\/span>iron or manganese) or other<\/b> elements <\/span>(such as<\/b> arsenic). In these cases, specific <\/span>water treatment plants<\/b>\u00a0 are used: <\/span>selective<\/b> filtration with<\/b> pyrolusite for the <\/span>removal<\/b> of iron and manganese (deferrization and demanganization); selective filtration with<\/b> ion-exchange resins for<\/b> heavy metal removal; Selective filtration with\u00a0 titanium dioxide or modified zeolites for the removal of arsenic.<\/span><\/p>\n<\/div>\n

Softening of water<\/div>\n
\n

The <\/span>hardness of acquasi means<\/b>\u00a0 a value that expresses the total content of calcium and magnesium ions and any heavy metals, due to the presence of soluble salts. The hardness of water can be reduced by filtration <\/span>on a softening plant, or with the<\/b> aid of a <\/span>water treatment<\/b> plant<\/b>.<\/span> The water<\/b> containing <\/span>an ion<\/b> exchange<\/b> resin<\/b> consists <\/span>of<\/b> a polymer bearing sodium ions (Na+). These sodium ions are exchanged with the calcium and magnesium ions naturally present in water. The hardness is then retained by the resin which is subsequently regenerated by treatment with\u00a0 concentrated salt water (NaCl) (brine). The water softener then removes the\u00a0 calcium and magnesium ions which make the water hard and replaces them with sodium. Depending on the type of water required, the softening can be total, that is, the water is completely softened with a residual hardness equal to zero, or partial, or maintaining a certain degree of residual hardness (this is often the case in domestic softeners).<\/span><\/p>\n<\/div>\n

Selective removal<\/div>\n
\n

Selective <\/span>removal is<\/b> a <\/span>process that aims to remove specific contaminants<\/b> or impurities from water, using<\/b> techniques and materials that act in a targeted manner on certain substances without significantly altering the composition of the water itself. Depending on the <\/span>contaminant to be<\/b> removed, <\/span>the process will take the name of<\/b> deferrization (iron<\/b>), dearsenification (arsenic) or demanganization (manganese). <\/span><\/p>\n<\/div>\n

Iron Removal Plants<\/div>\n
\n

Deference <\/span>plants<\/b> are designed<\/b> to remove <\/span>iron dissolved in water<\/b>, which can cause stains and metallic flavors. They use methods such as oxidation and\u00a0 filtration to convert soluble iron into an insoluble form that can be easily filtered.<\/span><\/p>\n<\/div>\n

Arsenic Removal Plants<\/div>\n
\n

Arsenification <\/span>plants<\/b> are used<\/b> to remove <\/span>arsenic from drinking water<\/b>, a contaminant known for its toxic effects. These plants often employ techniques such as <\/span>adsorption on<\/b> specific materials (e.g., iron oxides) or ion exchange processes.<\/span><\/p>\n<\/div>\n

Manganese Removal Plants<\/div>\n
\n

Deorganizationplants are <\/span>designed<\/b> to<\/b> remove <\/span>manganese from water<\/b>, which can cause aesthetic and taste problems. Similar to deferrization plants, they use oxidation and filtration\u00a0 to convert manganese into an insoluble form.<\/span><\/p>\n<\/div>\n

Heavy metal removal plants (chelating resins)<\/div>\n
\n

Plants using chelating resins are effective<\/b> in removing <\/span>heavy metals<\/b> such<\/span> as<\/b> lead, mercury and cadmium, zinc, nickel, copper. Chelating resins selectively bind heavy metals, allowing them to be removed from water\u00a0 through ion exchange processes.<\/span><\/p>\n<\/div>\n

Ion exchange resin plants<\/div>\n
\n

Ion <\/span>exchange resin plants use<\/b>\u00a0 synthetic <\/span>resins<\/b> to remove unwanted ions from the water and replace them with less problematic ions. This method is effective to reduce <\/span>water hardness (removal<\/b> of calcium and magnesium) and to remove other specific contaminants such as nitrates and heavy metals.<\/span><\/p>\n<\/div>\n

Stripping towers<\/div>\n
\n

Stripping <\/span>towers<\/b> are used<\/b> to remove <\/span>gases dissolved in water<\/b>, such as carbon dioxide, ammonia and volatile organic compounds. The process takes place by passing water through a column filled with filling material, where it comes into contact with a flow of air or gas which facilitates the removal of dissolved gases.<\/span><\/p>\n<\/div>\n
