From a purely practical standpoint, this beats high-capex mechanical and other solutions that can sometimes eliminate algal bloom, but do nothing about resulting cyanotoxins, or eliminating the actual cause of the HAB. Naturally occurring EBT microbes, on the other hand, consume the toxins, eliminate the bloom, and solve the underlying problem by bringing waterborne nutrients back into balance. This fixes the nutrient overload problem caused by watershed runoff and will stop future blooms from occurring if the EBS-Di continues to be implemented.
Of course, because agriculture and other nutrient land application will continue, and will keep running off into waterways, the waterbody will always have to be treated and brought back into balance. That said, the automation of the EBS-Di allows for economic and environmental adaptation. This means that once the initial HAB issue is remediated, the EnBiorganic team can easily adapt their service technology to accommodate the requirements of the waterbody through its remote control and monitoring capabilities.

Utilizing the EBS-Di technology the city is saving $400,000 a year on sludge handling as the sludge is now Class B sludge, now applicable for land application. As an added bonus the city has also seen a 37% reduction in KW hours after just 60 days of treatment at a 1 MGD SBR WWTP.
According to Monthly Monitoring Report (MMR) data—within 60 days after installation, Silver Spring realized visible evidence of 23% biosolids removal, 63% total solids reduction, nearly 100% odor eradication and a significant reduction in FOG (Fats, Oils and Greases).
Also noted was a change in effluent chambers which are now noticeably cleaner and easier to maintain once treatment commenced. Algae growth which typically required pressure washing and physical scraping to remove, can now be eliminated by a normal water hose. Over time the microbes will continue to progress upstream and positively impact other portions of the system.
At only 90 days into operation, 46% of the total estimated savings anticipated by the EIR have already been reached and this will rise over time.

“The results were shocking. BOD has dropped to 5.5 milligrams, TSS is down to 5.2 and total nitrogen is at 10.9 and we are in compliance. We’re very pleased with what we’ve seen, and it seems to be working very, very well.”
- BOD, TSS and total nitrogen concentrations have consistently met NMED’s Class 1B efficient reuse limits since the system was installed.
- Lagoon now has a nice, fresh odor to it, typical of a biological activated sludge plant.
- Lagoon floc is uniform in size, and now settles out evenly.
- Chlorine contact chamber clarity has improved to 2-3 feet, from previously less than one foot. We have noticed a slight reduction in fats, oils, and grease within the splitter boxes. Not certain it’s because of the system we put in. That may be because of the RVs moving out a little bit, but it has shown up.
- Sludge volumes—checked before we started and afterwards—have shown substantial decrease within the lagoon.
