FILTER MEDIA

Filtering through a filter bed is a widely used technique for removing particles containing water, its main applications are in drinking water treatment and water purification filtering media are materials that They allow the passage of the raw water through them and retain the particulate matter. They are selected based on desired physical characteristics, such as specific size, gravity and particle sizes.
KEIKEN Supplies High quality filter media, ideal for use in wastewater treatment and water purification.

Anthracite

Anthracite is a high-hardness mineral coal characterised by its highly carbon content, which can reach up to 95%. The shape of the anthracite grain facilitates the retention of suspended solids.
It is an excellent filtration medium for water clarification, as well as for single bed filters and mixed bed filters.
The product that KEIKEN provides comes from Germany and Russia. It is a high quality product, ideal for its application in wastewater treatment and brine purification.

Activated Carbon

The activated carbon is an adsorbent with high carbon content and a high internal porosity, and therefore a large free surface for adsorption. Thanks to its characteristics, the activated carbon effectively allows the elimination of unwanted substances, mainly organic matter and chlorine, in both gases and liquids.
The active carbon has a wide range of applications at the industrial level. These include water purification, wastewater treatment, and air and gas purification among others.
In KEIKEN we maintain exclusivity agreements with Indian manufacturers, which allow us to have an unbeatable quality of the product and with a very competitive price.

Garnet

Garnet is a chemically inert high density medium. Its chemical properties, hardness and durability make the garnet an ideal filtration medium.
Between the applications of the Garnet stands out his employment in the purification of waters, treatment of residual waters and treatment of industrial efluentes. It is one of the most suitable filtering media for filtering corrosive effluents.
Garnet is usually used as a support layer in mixed-bed filters, although it is also suitable for single-bed filters.

Sand

Sand is one of the most used materials as filtering medium for water filtration, both for water purification and wastewater treatment. The suspended particles containing the water are retained during their passage through the sand filter bed.
The sand supplied by KEIKEN is subjected to a process of washing, drying, and a classification, thus obtaining a precise particle distribution sand, suitable for use as a filtering medium.
With this process you can achieve different compositions and particle sizes completely controlled to meet the needs of each customer.

Gravel

Gravel is used as a support for filtering media, being an economic material and that does not give any characteristic to water.
The gravel supplied by KEIKEN have physical properties that make it a high quality product, suitable for water filtration applications for both purification of waters and wastewater treatment.
KEIKEN provides custom gravel ratings to meet each customer's requirements.

Manganese Dioxide(Aquamandix)

Aqua-Mandix is mainly composed of manganese dioxide and is characterized by high catalytic activity. The manganese dioxide concentration may vary by 55-85%.
Aqua-Mandix is used as a filtration medium for water clarification and wastewater treatment, it is an ideal material for the removal of iron and manganese from water.
