Horpovel® GmbH
Application-specific cleaning concepts
The speciality of Horpovel® GmbH
is ensuring flawless dairy products.
As an expert in the manufacture
of cleaning and disinfecting
products for the dairy industry, they
focus is on cleaning membrane filtration
systems. For the cleaning of membrane
filtration plants, the company relies on cooperation
with membrane manufacturer
Koch Separation Solutions* and various
other plant manufacturers.
Good cleaning is result-oriented, costeffective,
reproducible and achieves a
stable result. For this reason, Horpovel®
GmbH has developed application-specific
cleaning concepts (hereinafter referred to
as Horpovel® AR concepts) for its customers.
These concepts are used both in general
CIP cleaning and in membrane cleaning.
Based on operational conditions, Horpovel
® AR concepts can include not only
an adjustment of temperature, time and
concentration levels, but also the revision
of the chemical component in terms of ingredients
and set-up of the cleaning process.
(Figure 1)
The dual-component verification employed
by Horpovel® and the use of the
Horpovel® additive system (see technical
article on www.horpovel.de/press/), the
appropriate cleaning concept can be found
and applied specifically to the respective
process and the existing conditions. Extensive
experience of Horpovel® has shown
that only an adaptation to the respective
process and the specific conditions brings
the best cleaning result. Thus, generalised
cleaning concepts cannot achieve such a
high level of effectiveness.

Horpovel® AR - concepts make it possible
to work in a resource-saving and reproducible
way. Especially in the field of
membrane cleaning, the core competence
of Horpovel® GmbH, the AR - concepts are
a successful way of working. In the field
of membrane cleaning, this means an intensive
examination of the current cleaning
procedure by our experienced application
engineers with subsequent target definition
for the creation of the new cleaning
concept.
With a variety of technical devices, it is
possible to obtain a meaningful database of
the existing system and, on its basis, to develop
an appropriate concept adaptation.
Since filtration membranes change during
their life cycle, this cleaning concept is continuously
adapted and optimised by Horpovel
® application technology.
Selection and design of the
right sequence of cleaning
steps
For all membrane cleaning, the cleaning
must be based on the processed product
and the local conditions. This information
is used in process analysis to work out
which cleaning steps are sensible and necessary.
In addition to the sole cleaning effect
of a step, the set-up of the membrane
and microbiology also must be considered.
Based on experience gained from the
AquaECON® concept developed with ALPMA/
LTH Dresden, a new approach to rinsing
optimisation in membrane plants was
derived. In conjunction with an advanced
chemical-physical process analysis of the
cleaning by Horpovel®, rinsing phases can
thus be significantly shortened to save resources.
In cooperation with
MEMBRANREINIGUNG
In addition to the optimal sequence of
steps, significant savings potential must be
considered in choosing the exact parameters
of circulation and rinsing. By adjusting
the circulation steps, reductions in chemical
dosing of up to 5% and more are possible.
The intermediate rinsing steps adapted
to the Horpovel® concepts generate reductions
of up to 20% and more over conventional
rinsing steps.
Enzymatic cleaning steps often are very
important for successful cleaning. For enzymatic
cleaning to be effective, optimal
timing is essential. If the plant is not optimally
prepared, it can happen that the
enzymes do not act at the intended target
locations of the plant. Rather, the most effective
time should be determined through
process analysis.
As part of process analysis, step times
are optimised based on chemical-physical
parameters. In addition, energy consumption
is reduced by effective parameterisation
of the steps. In addition to adaptation
of cleaning steps, significant potential
results from observing the right cleaning
chemistry. In addition to residue analysis in
membrane autopsy, processing of technical
conditions and requirements should be
mentioned.
Depending on the membranes in use
and their requirements, it is crucial to consider
the accuracy and speed of dosing. If
the conditions are right, the implementation
of the Horpovel® additive system can
bring decisive cost advantages. (Figure 2)
