Handling large quantities of abattoir wastewater the
Grundfos way
Grundfos way
THE GRUNDFOS SOLUTION
All wastewater is collected in a pump pit and pumped onwards into a mechanical screen, where all solid
waste is separated out. These solids are then transported to a special waste-disposal site. The first pit
contains two 100 mm S-type sewage pumps with channel impellers, providing performance of 20 l/s x 25
mWc. The 200 mm discharge line extends to 500 m.
The pumps are mounted on complete guide-rail systems, thus ensuring fast and easy servicing. Frequency
control allows a continual adjustment to pit levels, and the pumps are alternated on a weekly basis.
Once the solids have been removed, the wastewater is transferred to a second, similar pit. From here, it is
pumped onwards to the public wastewater treatment plant.
THE OUTCOME
The chief engineer responsible for the day-to-day operation of the abattoir is very pleased with the new
Grundfos solution: “Since October 2000, all pumps and controls have provided an admirable performance
in this unique and demanding environment”. Once again, Grundfos solutions prove that they will match
anything, even highly specialized heavy-duty applications.

THE GRUNDFOS SOLUTION
This protection was not, however, adequate. Following repeated breakdown episodes, the engineer
responsible for day-to-day operation decided to replace the inefficient pump with a Grundfos CRN Air-
Cooled Top pump, featuring the air-cooled shaft seal that is unique to Grundfos. This pump is capable of
handling water of up to 180°C without needing any external cooling water.
In special situations, particularly in connection with start-up, the pump may operate against lower counter
pressures which could cause cavitation. To prevent this, the Grundfos CRN pump is fitted with a special
prechamber and impeller, ensuring that the NPSH value remains low – irrespective of the flow.
THE OUTCOME
The advantages outlined above – a pump which successfully combines high temperatures and high
pressures – resulted in a pump solution which has now provided the client with a whole year of trouble-free
operation.

SAME SETUP – DIFFERENT SOLUTION
A major sugar manufacturer had similar needs, with identical condensate
returns. In this case, losses due to friction were 16 mWc. Until recently, the
system used comprised six pumps made by another manufacturer. These
pumps needed external cooling water to protect the shaft seal against high
temperatures.
When the plant was due for renovation, the chief engineer decided to replace
the pumps with six Grundfos NKG 125-250 pumps. These pumps are fitted with
Burgmann Cartex double seals which use glycol as coolant.
Temperature differentials are used to circulate the glycol, ensuring that even
though the pump operates at 160°C, the glycol will never reach a temperature
higher than 70°C. Thus, the Grundfos solution eliminated the need for external
cooling water.

THE SITUATION
A leading textile dye works based in Scandinavia supplies
fabrics for the automobile industry. The quality standards
within this area are extremely demanding: the colours
need to be 100% consistent from batch to batch. Of
course, this calls for exact dosing of the dyes used. The old
solution, supplied by another manufacturer, featured
pumps that where time consuming and troublesome to
calibrate.
In fact, the problems rose to a level where the company
had to allocate 1.5 full-time employees to handle
calibration at all times. The task of ensuring precise dosing
at the plant is complicated further by the fact that the
pumps have to handle varying inlet pressures.

THE GRUNDFOS SOLUTION
As the overall problems with calibration became intolerable, the customer wanted to replace its old system
with a simpler, less time-consuming, and more accurate pump solution. The obvious choice was a Grundfos
Digital Dosing system with its straightforward “what you set is what you get” technology. This innovative
technology eliminated all need for continuous calibration: Grundfos Digital Dosing pumps provide
customers with fast and easy calibration and accurate capacity setting, facilitating smooth and even dosing
action. In addition to this, the user interface is so simple that the need for specially allocated staff
disappeared overnight: the desired volumes of dye are simply set by means of the easy-to-use digital
control panel, and the pumps do all the thinking.
THE OUTCOME
The Grundfos Digital Dosing solution has provided trouble-free operation for more than 18 months – with
minimal calibration of the system. Not only has this eliminated aggravation and delays, it has also freed up
human resources for other tasks within the company.

plant service systems | INDUSTRIAL WASTEWATER
THE SITUATION
This large-scale poultry abattoir
generates 1.5 million liters of
wastewater every day. Being full of
large chunks of debris, this industrial
wastewater needs to be filtered
before further treatment. All of this
means that the company needs a
solution which is capable of handling
huge volumes while also providing
highly specific wastewater treatment.
At the abattoir, wastewater is
generated from all production areas.
Consequently, pumps are called
upon to handle all kinds of waste and
refuse – including rubber gloves! The
local public wastewater plant will not
accept unfiltered wastewater, which
means that the abattoir has to carry
out an initial treatment to remove all
large solids from the water before
sending it on.

For brewing beer, only the best pumps are good

THE SITUATION
This 143-year-old brewery is the
leading domestic brand. It has
reached this dominant position on the
basis of its reputation for consistency
and due to
its dynamic product development
strategy.
It is essential for both production and
for the end product that the water
supply system runs reliably and that
the quality of the supplied water is
consistent. A failure could bring
production to a standstill and harm
the quality of the beer. There is also
strong competition among the
breweries to continuously decrease
energy consumption.

THE GRUNDFOS SOLUTION
Three Grundfos high-grade AISI 316 stainless steel CRN 64 pumps controlled by a central PLC system
supply all brewery water. One CRN 8 serves as jockey pump to maintain a constant pressure in the system.
The versatile CR pumps are used not only for the brewing water but also for the cooling water, heating,
cleaning etc.
THE OUTCOME
The original CR range has three decades’ reputation for reliability and the maintenance procedures are quick
and simple. Grundfos supplied highly efficient hydraulics and drives as well as the professional dimensioning
tool Win-CAPS to optimise the pump selection. Now the system runs very reliably and at optimum efficiency
– reducing the Cost of Ownership over the life cycle.
And maintaining that vital beer taste!
