Requirement

H+E, a leading international designer and supplier of industrial process and wastewater treatment systems, has received an order for a new biological wastewater treatment plant from the Bulgarian viscose pulp producer Svilocell.

In order to meet the future EU-imposed discharge limits into the River Danube, the previously purely mechanical wastewater treatment plant will undergo a major expansion by adding biological treatment prior to discharge.

Svilocell ultimately decided to work with H+E due to the company’s many years of expertise, as evidenced by nearly 80 plants designed and built for the pulp and paper industry, and also the very positive experiences expressed by those long-term customers. In addition, the fact that H+E’s design allows the new process steps to integrate compactly into the existing plant layout, thereby utilising the available space, was a positive factor.

Process

Before the mechanically cleaned wastewater is transferred to the new two-stage biological purification, it will first be cooled in an indirect cooling system to the temperature compatible with the biological process. The balanced combination of the BIOFIT®.H floating bed and the BIOFIT®.C aeration results in a cost-optimised solution.

In particular, the AEROFIT.V ventilation system contributes to the intrinsic value and energy efficiency of the new wastewater treatment system since it allows trouble-free operation over a period of decades with a consistently high oxygen yield.

Biochips with an especially high specific growth area are used as biofilm carriers.

Outcome

The chosen process line will equip Svilocell with a highly robust and efficient wastewater treatment facility from 2018 onwards, in order to fully meet the requirements for environmental protection.

    H+E UK
    The BIOFIT®.Oxyd2 process is used for the treatment of wastewater where the pollutants are difficult or impossible to remove using conventional biological processes alone. It uses a chemical oxidation process to break down non-biodegradable pollutants, making them available for subsequent biological treatment by microorganisms. The process enables...
