Kruger Inc.
I. Kruger, Inc. (d.b.a. Kruger Inc.) a provider of water and wastewater treatment process solutions, is a subsidiary of Veolia Water, one of the largest full service water and wastewater companies in the world. Kruger AS was started in Copenhagen, Denmark over 100 years ago. In 1989 Kruger AS established a subsidiary company, I. Kruger Inc, in the United States. In 1991 Kruger acquired the high purity oxygen wastewater business of Air Products and Chemicals Corporation to add to its growing portfolio of process solutions. In 1999 Kruger became part of OTV now Veolia Water and continues to build on it previous successes. By offering unique value added treatment equipment and processes, I. Kruger Inc, now located in Cary, North Carolina has grown to become a recognized leader in the water and wastewater treatment industry.

Neosep membrane bioreactor uses FibrePlate membrane technology to provide desirable footprint, energy and flux. Robust, reinforced, self-healing 0.04-micron polyvinylidene difluoride ultrafiltration membrane “fibers” are formed into a flexible sheet. This hybrid membrane technology offers an advanced hydraulic design. more
  • Neosep membrane bioreactor uses FibrePlate membrane technology to provide desirable footprint, energy and flux.

This hybrid membrane technology offers an advanced hydraulic design. more
  • Actiflo Carb enhances the removal of natural organic matter, taste and odor compounds, endocrine disruptors and pesticides with the combined benefits of ballasted clarification and the adsorption capacities of powdered activated carbon (PAC). It can be applied to both drinking water and wastewater applications. more
  • Anita Mox is a moving bed biofilm reactor for treating wastewater with high ammonia concentrations (200 to 2,000 mg/L). With patented controls, it removes nitrogen from side streams—such as those from anaerobic digesters—with 60% less air than conventional nitrification and no supplemental carbon. This significantly reduces the energy need and cost of operation in the main plant.  more
  • Biostyr Duo is a first-of-its-kind integration of biological aerated filter (BAF) and moving bed biofilm reactor (MBBR) technologies. Wastewater first flows through a dynamic MBBR media layer that provides a large surface area for biofilm growth and treatment. Flow then passes through the Biostyrene media layer, which provides additional fixed-film treatment and filtration as the water flows up... more
  • Bio Thelys is an enhancement to anaerobic digestion. It is a two-stage, batch thermal hydrolysis process, utilizing high-pressure boiling of biosolids followed by a rapid decompression. This process’ capabilities include increasing existing digester capacity by two to three times, increasing biogas production, producing Class A biosolids and increasing dewaterability up to 40%. more
  • BNR processes with real-time dynamic controls reduce aeration energy by 30% compared to time-based controls. Ceramic membranes provide a 10% to 20% electrical savings compared to other drinking water membranes. Discfilters offer a 40% to 50% energy savings over alternative tertiary filtration suppliers. The biosolids dryer and energy-recovery system can recover 100% of the dryer heating needs. more
