Pulp & Paper
Production of the pulp and paper that is required to manufacture so many of the products that we take for granted in our daily lives has traditionally been particularly energy- and water-intensive. In our modern world, where environmental considerations are increasingly important, there is an increasing requirement to optimise production. This is driven by both regulatory requirements (in turn driven by environmental concerns) and also the need to optimise operating costs.
H+E has a huge amount of experience in designing and building systems for pulp and paper industry projects. Today more than 400,000 cubic metres of wastewater are treated in H+E-built plants every year!
Whatever you need, whether it be production of process water, or treatment of wastewater, our proven experience can provide you with a reliable and energy-optimized plant designed to meet your requirements over many years.
