FOG Removal

Rapidly break down oils, fats and grease using Next FOG Stop

Enva have partnered with Next Filtration UK to bring the NFS technology to the market.  Rather than introducing foreign enzymes and bacteria as has been the traditional methodology in this area, Next FOG Stop is designed to stimulate the existing bacteria to rapidly breakdown fats, oils and grease present in the sewer and also to control hydrogen sulphide generation.

The formula is less costly and more sustainable when compared to expensive bacteria/enzyme treatments that generally provide short term local effects, but not long term benefits – particularly downstream of the addition points. If there aren’t sufficient indigenous bacteria present, then there is a problem with the existing environmental conditions, adding bacteria and enzymes as a consequence   is unlikely to have much effect.

Addition of the NFS product  to sewer networks will breakdown existing FOG deposits and prevent the build-up of FOG in the sewage pumping station down stream of the addition point, indeed the benefits of the addition can work through to the sewage treatment works.

As a result of the biocatalytic effect of the NFS product on existing bacteria, addition to WWTWs provides operational benefits.  Results can vary from one treatment facility to another due to differences in plant design and operating conditions, however 10 to 30% reduction in MLSS Sludge production has been achieved on a consistent basis at wastewater treatment plants.

The formula’s’ molecular technology – a liquid formula containing an optimised array of fermentation-based yeast proteins, micro-nutrients and highly specialised surfactant chemistry needs to be dosed at only a few parts per million to stimulate the indigenous bacteria population and accelerate natural bio-degradation. This approach

Benefits in Sewer Treatment

  • Reduction in noxious gases
  • Reduction is sewer blockages due to oils, fats and grease
  • Reduction in pumping station corrosion and sewer collapses

Benefits in WWTWs

  • Increased BOD and Nutrient uptake
  • Reduction in Sludge Generation
  • Reduction in blower energy consumption
  • Improved settlement
