In the present paper, the information on the influence of various factors on the carbon block cartridges
production technology and their potential impact on the properties of the finished product is presented. The
possibilities of increasing the sorption-filtering efficiency of carbon block cartridges are presented. The
technical and exploitation characteristics are influenced by the size of the mixture components granules, the
physicochemical properties of active carbon and binder polymers, their ratio in the mixture, and the addition
of bactericidal additives into the composition. The study of this topic is relevant, as evidenced by the analysis
of the increasing number of publications on this matter over the past ten years. However, the production
technology of carbon block cartridges is the know-how of manufacturing companies. This information is
confirmed by the analysis of the technical characteristics of sixty carbon block cartridges from nine world
manufacturers, whose products are WQA certified according to the NSF/ANSI 42 standard. The
recommendations given by a number of authors on the size of activated carbon granules in the range from
40 to 120 mesh and polyethylene particles from 80 to 160 mesh with a flow rate of 1.4-3 g/10 min, can be
taken as "reference points" in the development of extrusion mixtures with different components ratio. The
following factors play an important role in obtaining effective cartridges: the quality of pre-extrusion mixing
of the composition, its resistance to delamination during the “transition” from the mixer to the extruder
loading zone, extrusion temperature regimes by zones, product cooling temperature, backpressure on the
billet leaving the extruder. The information given in this article will be useful when producing new carbon
block cartridges, improving the parameters of existing technologies, as well as in the research development
of cartridges with new properties.
