BK-Hydrometa loves good challenges:

EFFE® water treatment technology has been developed to meet the special requirements of our customers and end-users.

The solution is scalable and very flexible for various types of waters and tailored especially for:

  • Perched water tables
  • Water containing dissolved metals
  • Hazardous runoff water
  • Chemical-contaminated ground water
  • Landfill leachate
  • Water containing nutrients or acid gases
  • Water in sedimentary basin

As a result of the treatment process, the amount of impurities will be reduced to the desirable levels and the effluent can be reused in industrial processes or released into water bodies according to the local environmental requirements.

To give us a good challenge – contact us!

EFFE® system is there to solve the following environmental challenges:

  • Low contaminated perched water tables and runoff waters, which need to be refined or are required for reuse in process.
  • Rainwater, leachate and snowmelt are gathered in storage ponds and water should be refined.
  • Residents of the local area have complained of odour caused by the water.
  • Stored waters that include impurities need to be treated for environmental or amenity reasons.
  • Need to be reduced the amount of hazardous substances in water and to be prevented their propagation to a larger area or into groundwater.
  • Contaminated urban runoff waters collected from large, roofed and paved areas or from rainwater harvesting systems.

Benefits of EFFE® treatment system:

  • It is based on biological remediation and can treat cost-effectively even 1200 m3/d
  • It allows highly efficient dissolution of oxygen into water and constant oxygen saturation level.
  • Undesirable volatile substances present in the water can be released and collected from the process for off-site treatment.
  • The environmental impact and the amount of used chemicals are significantly reduced compared to conventional treatment methods.
  • It has a low power consumption and a low environmental impact.
  • It tends to stabilize the pH value of the water to neutral.

Bacteria and other organisms that live inherently in water can split hazardous chemicals or modify harmful substances into another form.

EFFE® creates suitable circumstances for aerobic micro-organisms. The increased oxygen level improves their ability to live and grow, which is seen in their increased activity in biodegrading the organic matter by aerobic digestion.

The online measurements and the SCADA-system are essential parts of the runoff water treatment method. The fully automatic self-adjusting system allows to maintain the same efficiency even when water quality and quantity are changing.

EFFE® process is simple and has four variants:

EFFE® water treatment plants are preassembled at the Hydrometa’s production site in Raisio, and are delivered as a complete solution to the customers.

The functioning of EFFE® plant is ensured all year round by smart automation, HVAC system and thermal insulation. The process can be locally or remotely controlled.

EFFE® GX for gaseous substances in water

During the EFFE® treatment process the dissolved gases in water such as radon, carbon dioxide, methane, arsenic, hydrogen sulphide, will be released as a gas phase and removed from the process. At the same time oxygen is mixed into the water.

This ensures the good growth conditions for the microbes in the clarifying step and the particles will settle down as a sediment.

EFFE® GX reduces gaseous substances and hazardous chemicals in runoff water.

EFFE® RA-V for nutrients in water

The water treatment method EFFE® RA-V is developed for runoff waters in mold and fertilizer industries, in landfills or in quarries where the explosive residues are present.

The optimal process result can be achieved by adding an appropriate and effective adjuvant or flocculant into the water.

SPEF® for water in sediment ponds

SPEF equipment is a floating platform, which has been developed to dissolve oxygen into the water that bacteria can utilize in their breakdown processes.

SPEF has given excellent results during the in-situ trials and in long-term development succeeding to dissolve up to 15 mg / l of oxygen into the water.

Stagnant waters typically have a low oxygen level.

When combined with the high organic load and suspended solids, the lack of oxygen causes the turbidity, algae growth and foul odour in ponds with stagnant water.
