B220R is a desiccation-tolerant blend of selected microbes specifically designed for biodegrading fats, oils and greases (FOG). B220R neutralises odours in sewers and pump stations.
It softens and cleans grease build-up in pump station wet-wells, mechanical equipment, rising mains and gravity sewer lines. It also:
* Reduces odour
B220R microbes out-compete sulphide-causing bacteria that thrive under anaerobic conditions, thereby eliminating undesirable sewage odour – especially in slow cycling stations where fermentation of sewage may occur.
* Prevents sulphide gasses and corrosion
Countering anaerobic degradation leads to the elimination of sulphide gas production – a by-product of anaerobic fermentation/degradation – which in turn forms corrosive sulphuric acid that attacks masonry, metal fittings and electrical switchgear.
* Reduces scum
Gels and solids floating on the surface and lining the sewer walls are permeated by the introduced B220R microbes, which systematically degrade these pollutants from the under side.
* Prevents fat rafts
When FOG coagulates it forms ‘rafts’ that interfere with volume-sensing switch gear. B220R helps by preventing the rafts from forming.
* Decongests clogged floats
This constant cause of pump station malfunction is easily remedied by B220R as it efficiently breaks down the dried fatty deposits encrusting chains and floats.
* Purges rising mains
The small percentage of B220R microbes that ‘bleed’ past the pump will attack the fat lining the walls of the rising main during the rest cycle. As a result, the throat of the sewer gradually opens and returns to its design diameter reducing back pressure on the pump with consequent savings in the amount of current drawn.
* Benefits up-line
By countering the anaerobic conditions in long rising mains (LRM), B220R delivers a better quality effluent to the up-line wet-well with a consequent reduction/prevention in odour.
* Improves effluent quality
After dosing routinely for two months, B220R will deliver a better quality effluent with reduced FOG to the WwTW, purging sewers and pump stations as its influence progresses.
* Reduces effluent load
The final destination (the WwTW) will ultimately benefit from the routine dosing, reducing the organic load and allowing improved sludge settlement.
* Extended residence time
As B220R ‘lives’ in the top 300mm of the wet-well, the majority of the microbes remain within the pump station chamber (wet-well) ensuring long-term activity.
