Stroumboulis products

Imported from the Dutch manufacturer brand Filcom bv, which is active in the production and treatment of graded Silica since 1930. The fully automated production process is in line with the ISO 9001:2008 standard, whereas the capacity of the two factories in Papandrecht and Wessem is over 150.000 tn per year.

Imported from the Egyptian manufacturer brand RAWASY. Featuring high levels of chemical purity (SiO₂ 98,0% – 99,8%) and available dry and graded in standardised granular sizes.

Glass Filter Media, derive from recycling of glass products, therefore it is an environmentally friendly and recyclable product. Bottles, glazing and other glass products are crushed in special recycling facilities and then the product is washed, dried and finally classified in grain sizes, suitable for use in common sand filters.

Calcium Carbonate is an inorganic compound with the chemical formula CaCO₃ and is a type of salt. It consists of three (3) chemical elements: calcium, carbon and oxygen. It is a common ingredient of rocks in (almost) all parts of the world, as well as a main ingredient of exoskeleton sea (mostly) organisms, such as snails, sponges and corals. It is also a key component in pearls and egg shells

Garnet is a silicate mineral deriving mainly from metamorphic rocks, however it can also be found in magmatic rocks. It can be found close to water streams as well as metamorphic and igneous rocks. It has a deep red colour and its name comes from the latin word “grantum” (pomegranate). Garnet sand (Almandine) is naturally occurring in many parts of the world, extracted, cleaned and used as a filtration medium.

Activated Carbon is an extremely porous material with very large internal surface, ranging between 600-1500m²/gr. These features allow it to retain a number of elements from liquid or solid masses.

Dolomite is an anhydrous carbon mineral consisting of calcium and magnesium – CaMg (CO₃)₂. It offers 21,7 kg of calcium and 13 kg of magnesium per 100 kg. Dolomite can be dissolved in slightly acidic water.

Anthracite Filter Media (Hydro Anthracit) is a totally natural mineral material used for water refining. It is placed on:

Manganese is a chemical element with the atomic number twelve (12) and chemical symbol Mg. It is an alkaline earth mineral, the eighth in abundancy in the Earth’s crust (2% by mass) and the ninth overall in the universe. Its name comes from the area of Magnesia in Thessaly. Manganese Dioxide is formed through chemical treatment, but can also be found in nature.
