WHY USE BIOAUGMENTATION? Although man has used various biological processes for centuries in making beer , cheese , and wines , it has only been during the last century that most of the microbial processes have been understood . The value of seeding with specific organisms to maintain consistent , uniform high quality , rather than relying on organisms there by happenstance , has now been accepted by the food , beverage , pharmaceutical and chemical industries . The use of bioaugmentation in pollution control has grown over the past twenty-five years . In many biological wastewater treatment systems , ubiquitous bacteria can sufficiently degrade the wasteproducts . However , systems are fre- quently subjected to unusual compositions , heavy organic loadings , incon- sistent loading or those beyond design capabilities . Problems develop , and bacterial supplementation can provide effective solutions . Many facilities have found bioaugmentation invaluable to : Improve BOD removals Increase settleability Cower sludge volumes Control hydrogen sulfide emissions Eliminate grease mats Give consistent , predictable performance Prevent blockages within lines Restore percolation in fields and seepage pits Accelerate startups and recoveries from upsets Breakdown organic accumulations Provide onsite detoxification of troublesome organic compositions Reduce chemical needs Lower defoamer costs Extend life expectancy of treatment facilities Abate offensive odors Eliminate costs and headaches associated with noncompliance Reduce energy requirements USING ADVANCED BIO CULTURES FORMULATIONS The culture formulations are supplied in dry form . They become fully activated when presoaked for four to twelve hours in lukewarm (80'F to 100°F) water with eight hours being ideal . Two gallons of either Lap water or wastewater are used for each pound of cultures formulation . If the wastestream is cool , the slurry should be cooled to the approxi- mate temperature of the wastestream during the presoak to avoid thermal shock . The slurry should be stirred occasionally during presoaking . After presoaking the cultures slurry should be added as far upstream as practical . Introduction within the interceptor system has proven effective in pretreating the wastestream ahead of the treatment plant itself . Additions should in any event be ahead of primary clarification . For lagoon applications the slurry should be applied over the surface of the entire lagoon . 10Where liftstations are being treated , applications should be made through manholes upstream from the station itself .
