Services - BDL Környezetvédelmi Kft. 

The detection of residual contamination accumulated in groundwater, the exploration of the extent of contamination, the mitigation and elimination of residual environmental damages from the past are all part of the tasks of environmental remediation activities.

Not only the professional design and construction of the water delivery systems can protect our irreplaceable resources, the drinking water sources and ground waters, but we also have to take care of the protection and purification of these water resources.

We have exceptional references in the field of environmental remediation, we have contributed to the sustainability of our water resources with the design and implementation of several unique water management systems.

BDL is offering a comprehensive set of services for soil and groundwater contamination elimination, encompassing engineering, consultancy and construction works. Our aim is to return a “clean” environment to our clients after the contamination assessment, demarcation and reclamation.

One of the main missions of our company is to protect the quantity and quality of our waters, and the conservation, and improvement of the aquatic environmental conditions. Our water purification projects (iron, manganese, heavy metals, arsenic, etc) are conducted in accordance with the standards of the domestic and international legislations. We pay special attention to the expansion, the conversion and reconstruction of existing facilities, we carry out our activities in a sustainable and cost-effective manner.

 

Among our previous successful projects, in addition to water purification assignments, we also designed and managed the construction of river surface water intake facilities, water treatment structures, and the mechanical engineering of the above.

 

Applied units of water purification technologies:

  • Coagulation
  • Flocculation
  • Clarification
  • Sand filtration
  • Membrane cleaning
  • Ultrafiltration

Nowadays frequent environmental problem is caused by the changing, increasing nature of heavy rainfalls, parallel occurring with continuous urbanization. In urban environments the rate of the covered surfaces has grown drastically in the previous decades. Unlike natural, green surfaces, impervious surface prevents rain infiltration to the soil, resulting in increased volume of runoff water. The lack of proper stormwater management can lead to several problems, both quantitative and qualitative ways. Flooding, overloading the existing rainwater collection, and sewer systems might occur. Besides the high sediment load, urban runoff waters can carry lots of other pollutants, for example: oils, heavy metals, fertilizers, PAHs, endangering recipient water bodies.

We believe that rain water is one of our most important natural treasures. The collection, cleaning, storage and re-use of rain water contribute to one of our most important targets: the preservation of the quality and quantity of our precious waters.

In this spirit, we prepare civil; mechanical; electrical and control engineering plans for stormwater management projects and their engineering facilities, stormwater drainage and management plans for industrial parks, highways and other major investments.

We provide a full range of services from stormwater management concept plans for municipalities and river basins, to the management of the implementation of the project. It is important for us to recycle rainwater, and to reuse it for irrigation and for fire water systems if possible.

Our innovative, patented solutions in the field of stormwater management are exceptional. In addition to the products, the installation methods are also environment-friendly, economical and efficient.

We are proud to have designed several pre-treatment facilities during which we were able to develop our own range of devices and equipment that have been installed and successfully operational.

Our company possesses a wide range of experiences and professional references in the field of municipal and industrial wastewater treatment. Besides designing the wastewater treatment technology that meets the requirements, we consider the cost-effectiveness and the selection of optimal solutions as a key factor.

 

For the technologies designed by BDL, we provide full technological guarantee, we provide the manuals and plans for the trial run, and if requested, we can supervise, evaluate, the trial run period as well.

 

At the beginning of the planning and design process, we always conduct a specific technical, short-term and long-term economic and profitability analysis, in order to select the best suited solution in accordance with the customer’s needs.

 

We support the economic aspects and decision of the project with Life-cycle cost analysis, in order to provide our clients with unique and specific solutions.

 

Municipal wastewater treatment

Besides “green fields” investments, we undertake the design tasks of refurbishment, reconstruction, intensification and extension of existing technologies as well.

 

Municipal wastewater treatment technologies:

  • Mechanical cleaning (mechanical grid, sand trap, grease trap, pre-decanting, equalization)
  • Biological treatment (activated sludge technology, SBR, fixed -film systems, membrane technology)
  • Tertiary treatment
  • Wastewater sludge treatment: sludge thickening, dewatering, conditioning
  • Sludge digestion, composting, biogas usage
  • Disinfection

 

For a higher efficiency:

  • The BIOCOS (Combined Biological System) technology is the improved version of the aerobic activated sludge process, combining the benefits of traditional flow systems and the SBR basin (compared to conventional sludge separation processes it is significantly better, with a minimal mechanical demand, reduced energy consumption and maintenance requirements).

 

Industrial wastewater treatment (paper industry, food industry, textile industry, chemical industry, oil industry) technologies:

  • Mechanical cleaning (mechanical grid, sand trap, grease trap, pre-decanting, equalization )
  • Physical- chemical purifying (Flotation - DAF, coagulation, flocculation)
  • Biological treatment (aerobic and anaerobic)
  • Membrane technologies ( micro, ultra, nano filtration, reverse osmosis)
  • Wastewater sludge treatment ( sludge dewatering, conditioning)

 

Full range of engineering, construction and investment preparatory tasks:

  • Technical Condition and Environmental Assessment (eco-audit)
  • Concept design, master planning
  • Conceptual authorization
  • Management of licensing processes
  • Preparation of tender documents and construction plans
  • Coordination implementation (production, transport , technical supervision)
  • Test operation documentation and supervision (management, remote control and supervision)
