Abstract—Some water treatment way of industrial water on the local plants are presented herein. An application
of the suggested ways allows the treated water to reuse and to optimize operating costs.
Agitation is extensively used in a chemical and a
related branches of industry for preparation of emulsions,
suspensions, homogeneous systems, and also for
enhancing the chemical, heat, and diffusive processes.
Let us consider the agitation as a way for enhancing
the chemical, heat, and diffusive processes in the homo-
and heterogeneous systems. These processes are applied
to absorption, evaporation, extraction, and other chemi-
cal technologies because a good mixing of components
provides optimum conditions for feeding the substances
to a reaction area, an interphase boundary or a heat ex-
change surface. The enhancing of exchange processes is
performed primarily due to :
− increase of phase contact area;
− increase in the speed of relative movement of
− use of nonsteady regimes of an interphase exchange
that provide reaching high instantaneous values of mass
transfer coefﬁ cients;
− executing the mass exchange in hydrodynamically
unstationary conditions of the interphase surface.
Ways and selection of devices for agitation are de-
termined by a target of agitation and an aggregate state
of mixed materials. The agitation in the liquid media is
extensively used in chemical industry .
Direct ﬂ ow mixing of components for concentration
equalizing on a cross sectional area normal to a velocity
vector is one of the agitation ways in the ﬂ uid media.
For estimation of an operation efﬁ ciency of such devices
analogously to mechanic agitators the following charac-
teristic features can be marked:
− energy loss;
− intensity or degree of the agitation;
− agitation efﬁ ciency.
The energy loss of a mechanical agitators is expressed
by the driver power consumption that reveals the amount
of spent energy for an overcoming the friction force of
the agitator blades against a liquid.
In a case of the direct ﬂ ow agitation a pressure drop on
the agitation section of the device including the feed area,
the agitator, and an area of stabilizing movement can be
assumed as parameter deﬁ ning the energy loss.
At the agitation of the liquid components in a pipe of
the constant cross section the pressure dropped owing to
hydrostatic constituent and therefore the energy loss is
characterized only by the pressure drop.
THE INTENSITY OF THE AGITATION
Usually the intensity of the agitation is deﬁ ned by
time of reaching the given technological result or at
the mechanical mixing by the speed of the agitator at a
given duration of the process. The agitation intensity is
the higher the smaller is the time spent for reaching of
the given agitation result. The enhancing of the agitation
results in the decrease of the designing devices and in an
output rise. It is required from the economic point of view
that the target agitation is reached in the shortest time.
A quantitative estimation of the agitation intensities
of the direct flow agitators should be related to the
