BIOdek helps new wastewater plant in Nicaragua’s capital city, Managua, cut costs and reduce energy consumption
A BIOdek plastic media trickling filter system is helping a wastewater treatment plant resolve a wastewater management challenge that has been more than 80 years in the making.
The Managua wastewater plant is located on the shores Lake Managua, one of Central America’s largest fresh water reservoirs, near the country’s capital city. The plant is tasked with decontaminating the lake which, for more than 80 years, has been polluted by the unregulated flow of household sewage and industrial effluent.
The plant’s management went back on its original plan to install an Activate Sludge system after being impressed by a 2H specification that clearly demonstrated the advantages of a BIOdek Trickling Filter solution in helping the plant save money, reduce energy usage and carbon emissions and, importantly, in helping restore the lake’s damaged ecosystem. The proven reliability, ease of management and control for which BIOdek is renowned helped confirm the plant’s decision.
The 2H BIOdek plastic Trickling Filter system delivered the following benefits:
- Low operational energy demand: The BIOdek solution will consume 21 kwh per kg of BOD removed less than half the power consumed by an Activated Sludge system.
- Cost Savings: the energy-efficient BIOdek trickling filter system will generate annual savings of around €550,000
- Optimum Effluent Quality: the BIOdek solution is already delivering final effluent quality of 14mg/
- Low Carbon Footprint: the production methods used by 2H combined with ease of transportation and on-site installation of lightweight, modular plastic media generates low levels of carbon dioxide. The savings continue throughout the operational lifetime of the system as plastic trickling filters produce far lower levels of carbon dioxide than a comparable Activated Sludge plant.
