Abstract—Properties of ﬁ ltering-sorption materials based on basalt ﬁ bers and bentonite clays intended for
the removal of oil products from water were studied. Optimal parameters of a feed providing the maximal
puriﬁ cation efﬁ ciency with the minimal power consumption were determined.
Oil products are ones of the most widespread con-
taminants of natural ponds; they are brought there with
sewage of factories, upon petroleum production and
transportation, and with storm run-offs.
Despite the perfection of petroleum production, pro-
cessing, storage, and transportation technique and the
presence of manifold schemes of water puriﬁ cation from
oil products, as a whole the level of pollution by these
products remains rather high .
The removal of sewage water from oil products is
necessary for making landlocked water-turnaround cycles
in the industries, but most heavy demands are imposed to
water dumped in natural ponds. For example, for ponds
dedicated to commercial ﬁ shing the maximal concentra-
tion limit should not exceed 0.05 mg l
. Therefore the
puriﬁ cation of petroleum-containing sewage is one of the
most important and technically complicated problems.
The process of the removal of oil products includes,
as a rule, stages of mechanical and physicochemical pu-
riﬁ cations, which in combination allow the removal of
contaminations up to a demanded level .
Of the existing methods of puriﬁ cation of petroleum-
containing water, ﬁ ltration in combination with sorption
are most interesting, the more so as the both of processes
can occur on the same material. At present various feeds
are offered, including ﬁ brous, which make it possible not
only to provide necessary separation efﬁ ciency, but also
to lower economic expenses .
New sorption materials based on mineral basalt ﬁ bers
and bentonite clays were developed for the puriﬁ cation
of petroleum-containing sewage.
To determine oil products in water, we used IR spec-
trometry, which was admitted as an arbitration method
according to GOST Р 51797-2001 . The measurements
were carried out on an IKS-40 device, which allows
determining concentrations of emulsiﬁ ed and dissolved
oil products in the range from 0.05 up to 50 mg l
joint presence of volatile and nonvolatile oil products.
For the preparation of model solutions we used the
fraction of AI-92 gasoline with boiling point above 110°С
and mineral engine oil as oil products polluting water.
To study the process of puriﬁ cation of petroleum-
containing water by ﬁ ltering-sorption technique, we have
mounted a pilot unit. Its main parts were a mixing feed
container, a ﬁ lter column, and a container for collecting
the ﬁ ltrate equipped with a rotameter for measuring water
consumption and a mercury differential manometer for
head loss ﬁ xation.
As a ﬁ lter feed we used a basalt ﬁ ber obtained from
a melt of rocks (basalt) at one of Barnaul factories. This
material is a promising sorbent for water puriﬁ cation
having an essential advantage-mineral non-polymeric
origin, which simpliﬁ es used feed utilization.
Depending on a preparation technique, a ﬁ ber can be
