Next FOG STOP brings improvement in effluent water quality in Brazil

08-11-2018

In Brazil, Next FOG STOP has improved overall effluent water quality. 

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 per cent, use of Next FOG STOP could allow the facility to operate under increased flow, and/or organic loading of up to 25 per cent 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 per cent removal to 57.7 per cent.

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

Furthermore, sludge production dropped from 11,089 mg/L to 7,546 mg/L, for an overall reduction of 31.95 per cent. 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.
