The end of last year saw the
opening of the new wastewater
treatment plant of the Balboa Iron
& Steel Works II located in Jerez
de los Caballeros, Badajoz.
The plant is currently operating at only a
quarter of its production capacity. However,
as new production lines are launched in the
factory, the volume of wastewater volume
shall also increase.
The new plant has been designed to treat
all of the wastewater generated by the
Balboa Iron & Steel Works I and II. The
water engineering has been developed with
the aim of directing the wastewater from
all factory processes to the new facility,
thus simplifying the whole water treatment
process.
The plant has a capacity of 4,800m3/day.
The purified water is treated to be reused
in the factory. Therefore, the wastewater
generated and the treated water form a
closed loop system.
The treatment process implemented is
comprised of the following stages:
- Screening of solids.
- Pumping and sifting of wastewater.
- Removal of sand and grease.
- Aeration.
- Chemical coagulation and flocculation treatment of wastewater
- Physical decanting treatment.
- Slow sand filtering of clarified water.
- Storage and pumping the treated water
to the factory.
- Thickening of sludge.
- Homogenization and conditioning of
sludge.
- Dewatering of sludge.

In addition to the water treatment described
above, the project included the following
elements:
- Control of the water supply collector from
a reservoir to the factory using hydraulic
actuated valves.
- Safety well for storage of the runoff from
the factory and subsequent treatment in
the plant, before being channelled into
the waterway.
MP’s Services Area shall be providing the
Balboa Iron & Steel Works with maintenance
services and technical assistance for the
WTP.
The wastewater generated and the
treated water form a closed loop system
The entire execution phase of the project
was completed in around eleven months.
The developer, contractor and project
manager all agreed that this was a very
short timeframe, considering the enormity
of the work carried out. The desire to ensure
the satisfaction of the client by resolving
the problems involved in the treatment of
wastewater in Balboa efficiently and quickly
motivates us to continue working with this
important corporate group in any future
projects that it undertakes. It also motivates
us to continue working in a sector in which
MP already has successful projects under
its belt, such as the renovations carried
out in the Sevillana Iron & Steel Works and
in many other industries in the metallurgy
sector
