General information on Anthracite Coal Media

Aqualat ® is an anthracite coal filter media that is a selected coal, mined and processed for water treatment. Aqualat ® producing technology was developed by LLC “TERS” under the auspices of the leading research centers. Aqualat ® guarantees safe and continuous operation requiring minimal maintenance due to its stable structure. Thanks to higher rates of mechanical strength (wearability and grind ability), lower intensity, and duration of backwashing of the filter material does not destruct during the restoration of its characteristics.

Anthracite Coal Suppliers in Bangladesh

City Water Purifier is a reliable anthracite coal suppliers in Bangladesh. We also supply all kinds of water treatment media to fulfill the high demand for the water filtration system all over the BD.

Fields of application

Aqualat ® filter media have found wide application in all water sectors and is used for potable, industrial, process, wastewater, and swimming-pool water.

Aqualat ® is used as filter media in both open and closed fixed bed filters for:

• removal of suspended solids
• condensate filtration
• protection of coal filters, ion exchangers, and RO membranes;
• filtration of reverse cycles

• filtration of coagulated water
• filtration of turbid well, spring, surface, and artesian water
• filtration of wastewater
• swimming-pool

Application of Aqualat ® in multi-layer filters leads to:

Improvements of filtration yield by

• increase in capture capacity of pollutants by the filter bed using in-depth filtration
• combine with fine grain materials as a lower material layer to cause improved and stable filtrate quality
• increase in protection against breakthrough since the filter run up to breakthrough will last longer than the filter
  run until the maximum design head loss has been reached.

Increase in efficiency by

• higher solids take-up capacity
• mechanical strength of the material and low attrition loss
• extension of filter runs
• saving of backwash water
• high filtration
