Next FOG STOP brings improvement in effluent water quality in Brazil

6 November 2018

At a municipal wastewater treatment plant in Brazil, Next Filtration’s Next FOG STOP has improved overall effluent water quality by reducing residual effluent biochemical oxygen demand (BOD) by more than 50%.

Combined with an increase in dissolved oxygen (DO) levels of 45.5%, use of Next FOG STOP could allow the facility to operate under increased flow, and/or organic loading of up to 25% or more.

The 40-day trial of FOG Stop, which alters the core metabolism of indigenous bacteria, also improved the rate of ammoniacal nitrogen removal from 31.9% removal to 57.7%.

In the test by Sabesp, the water and waste management company owned by São Paulo state, volatile suspended solids were reduced from 20% to just 13.3%.

Furthermore, sludge production dropped from 11,089 mg/L to 7,546 mg/L, for an overall reduction of 31.95%. Again, FOG STOP showed that the operating cost of handling and disposing of sludge at a wastewater treatment plant can be greatly reduced.

In England, Next Filtration recently secured a contract with Severn Trent to deploy its Next FOG STOP technology to cut down the build-up of fats, oils and grease (FOG) in sewers.

This agreement followed an extensive 18-month trial period, during which time Next FOG STOP significantly helped cut maintenance costs and flooding caused by blockages in sewers.
