Water plays an important role in the production of pulp and paper, which is a sector that requires large volumes of water. In addition, the wastewater generated in the production process is rich in
inorganic substances, which makes it difficult to discharge.
Today it is becoming increasingly important to treat wastewater and return treated water to the process, especially in the pulp and paper industry where large quantities of clean water are required for
the production process. There is also a high environmental impact to consider.
Water is used in almost every step of the manufacturing process at a pulp and paper mill. So of course these facilities have large volumes of wastewater to treat and sludge to dispose of. To save
costs, many mills would like to recover excess pulp fibres from their wastewater for reuse in the production line.
For those facilities that do not recover fibres, we have highly effective integrated thickening and dewatering systems with the fibrous material, reducing the volume of sludge and the associated disposal costs.
Most common applications
Disinfection
Industrial wastewater is a major source of potentially dangerous pollution. In order to protect the natural environment such as rivers, lakes, beaches and coastal areas, increasingly strict regulations
have been put in place to limit the release of pathogenic microorganisms from industrial discharges. This has led to many large-scale manufacturing facilities implementing UV and
Ozone as part of their wastewater treatment process.
The main reason why these two technologies have become the preferred solution over other alternatives is because they do not generate any chemical byproducts. This is exceptionally important
as discharge water is often already loaded with toxic chemicals. UV disinfection and Ozonation are also among the most effective solutions against almost all known pathogenic bacteria and viruses,
as well as chemically complex compounds.
Through advanced solutions such as Advanced Oxidation Processes (AOP), process water is reused, leading to cost savings and environmental optimization.
Primary Filtration
Filtration systems capable of effectively recovering over 95% of the wood fibers discarded in the papermaking process.
It is a combined rotary belt filtration and dewatering system designed for the efficient removal of solids and the production of compact, easy-to-manage sludge for wastewater applications.
The technology uses a patented process in which solids are separated from a wastewater stream and collected on a specialized filter mesh, while the subsequent filtrate is removed from the
mesh and concentrated by a simultaneous dewatering mechanism.

Filtration
The microscreen drum filter treatment, which can be used in the pulp and paper industry, cooling water, inlet process water and reuse systems as a pretreatment before UV. This
filter is designed for the reduction of TSS, BOD and COD.
Our disc filters can be used in the same applications as the microscreen drum filters.
Their main advantage compared to drum filters is their higher filtration capacity and filtration is also possible from 5 μm. This filter is also designed for the reduction of TSS, BOD and COD. The
innovative filtration technology guarantees high filtration efficiency with increased particle removal and low energy and water consumption for backwashing. This results in savings in operating
costs of the filter as well as in the further processing of the sludge. Which leads to a faster return on investment costs.
Mobile Plants (for rent)
Mobile water treatment provides additional capacity and rapid treatment for both long-term installations and short-term emergency relief.
A robust, cost-effective and flexible solution, through modular water treatment rentals on a medium to long-term basis. These solutions are tailored to the specific needs of the customer and
are commissioned, installed, operated and maintained to meet long-term requirements.
This is an ideal off-balance sheet solution for customers who:
✓ Have a limited budget for capital expenditure (capex)
✓ Have a limited perspective on the life of their production facility
✓ Are looking to reduce operating costs
✓ Need additional volumes of treated water
✓ Looking for a new project or replacement of an existing plant
✓ Want to be able to move the water treatment facility from one site to another
✓ Reduction in raw water costs
