BDL Környezetvédelmi Kft.

Waste water treatment

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)
