Three core processes;
1)
Biological Filtration
2)
Reverse Osmosis Membrane Filtration
3)
pH adjustment
Employs indigenous micro-organisms & natural metabolic processes to purify water Conditions conducive to the growth of specific bacterial populations are maintained
within bio-filters.
Biological filtration processes occur at a rate 10,000 times greater than in nature
Contaminants removed biologically are either nutrients or energy sources for the
bacterial populations
Some contaminants are consumed or remain within the biomass
i.e., Fe2+ , , NH4+
Others are transformed into compounds ideally suited to removal by the RO
membranes
i.e, Mn2+ to Mn3+ As3+ to As5+
Downstream heterotrophic plate count in treated water is < 2/ml
Canadian guideline is < 500/ml

Filtration material within the bio-reactors looks like coffee grounds Branded Filtralite, this media provides “5 Star Hotel Rooms” for bio-film forming bacteria By providing the right conditions, iron bacteria will remove iron, nitrifying bacteria will oxidize ammonium etc.

Highlighted compounds represent bacterial nutrients or energy sources treated in the Bio-filters
Non-Corrosive inorganically stable water
RO treatment yields water with a <pH 6 which is highly corrosive Corrosive water can leach out copper and lead from distribution pipes Re-adjustment of the pH is accomplished in a proprietary SIBROM mineral contactor
employing calcium & magnesium carbonate salts
DOC removal below detection limits
DOC reacts with chlorine and forms disinfection by-products many of which are
carcinogenic
i.e.trihalomethanes Removal of dissolved organics improves the effectiveness of chlorination
Typically Cl usage with SIBROM treated water is reduced by 90%
Reduced dissolved gases removed
Methane Hydrogen Sulphide
Environmentally sustainable process
Employs indigenous mico-organisms No pretreatment chemicals required RO concentrate is environmentally benign
Lower chemical costs
Lower Cl dosages Low antiscalent required
Reduced Backwashing
95% reduction in water used
Reduced reservoir cleaning
Coin test
Extended membrane life
Reduced membrane replacement Eliminates cleaning costs
Reduced labour costs
Backwashing Minimal operator interventions Continuous process Remote monitoring and intervention control systems
