Why EquaReact® for Municipal Wastewater?
The EquaReact® System allows municipal owners to uniformly equalize and treat wastewater flows over a 24-hour period. The system provides treatment and the required flow equalization volume to achieve 24-hour diurnal flow equalization and optionally provide stormwater inflow equalization at municipal wastewater treatment plants without aeration and the resulting wastewater carbon source consumption. This system also provides municipalities the ability to handle spike influent loads from their Industrial dischargers.
Why EquaReact® for Industrial Wastewater?
The EquaReact® System allows industrial owners to uniformly equalize and treat wastewater flows over a 24-hour period, seven days a week. This system provides treatment and the required flow equalization volume to achieve 7 day/24-hour flow equalization, as industrial wastewater treatment plants have daily diurnal inflow patterns and pollutant loading rates. This includes higher flows and pollutant loading during daytime processing shifts, lower flows and loads during nighttime clean-up shifts, and very low or no flow and loading during weekends and holiday shut-down days.
Applications – New Systems, Expansions, Upgrades and Retrofits
- Municipal wastewater flow
- Industrial wastewater flow
- Combined Municipal & Industrial wastewater flow
Typical Problems with Equalization:
- Reduction of BOD and impact on Biological Nutrient Removal
- Increased construction costs
- Long term O & M costs
- Potential odor problems
- Issues with scum and solids deposition
THE SOLUTION –The EquaReact® System provides real VALUE!
- Allows for influent flows to be equalized while maintaining Influent BOD as a carbon source
- Utilizes equalization volume as reactor volume to save on capital cost (no need for separate tanks or additional pumping)
- Eliminates odors associated with raw influent equalization
- Can be designed to provide both anaerobic/anoxic conditions for biological Phosphorus and Nitrogen removal
- Minimizes surge flows and maintains steady flow to clarifiers; improving performance
- Minimizes shock loadings allowing for steady chemical dosages
- Eliminates spike loads from industrial dischargers
In short your facility will realize:
- Reduced capital and operational costs
- Reduced land requirements
- Reduced energy consumption
- Increased total treatment system performance and energy efficiency
Operational Value of the EquaReact® System:
The operation and the efficiency of biological nutrient removal (BNR) systems is affected by viable daily wastewater inflow rates and volumes and pollutant loading rates that occur in municipal and industrial wastewater treatment plants. EquaReact® provides a real cost effective and efficient solution to these issues.
Municipal wastewater treatment plants have typical daily diurnal inflow patterns with higher flows and pollutant loadings during morning and evening hours and much higher surge inflow during stormwater events. Industrial wastewater treatment plants have typical daily diurnal inflow patterns and pollutant loading rates with higher flows and pollutant loading during daytime processing shifts, lower flows and loads during nighttime clean-up shifts, and very low or no flow and loading during weekends and holiday shut-down days. These variable wastewater influent flow rates and volumes and pollutant loading rates make BNR system design and operation more difficult, usually requiring automatic control and pacing of pumping equipment, aeration equipment and chemical feed equipment according to wastewater flow rate and other process control parameters. Wide swings in diurnal flow rates and pollutant loadings and weekday high flow vs. weekend low flow volumes and loadings impact the design of BNR process reactors, clarifiers, pumps and other equipment. EquaReact® will allow operators to manage and control their influent flows in a more productive and efficient manner, increasing the performance of their downstream treatment system.
In order to reduce the negative impact of variable wastewater inflow rates and pollutant loading rates, equalization basins are used to store, blend, and equalize variable wastewater influent flows and loads upstream of the BNR treatment process units. Storing raw wastewater in an equalization basin can produce odors unless the basin is operated with aeration to transfer oxygen into the wastewater. Aeration of the equalization basin results in the reduction of carbon source in the raw wastewater, which is needed in the downstream BNR process for nitrate-nitrogen removal by biological denitrification and for enhanced biological phosphorus removal. EquaReact® is a patented system that allows operators to manage and control influent flows through equalization, provide treatment, and eliminate odors while maximizing raw wastewater carbon source all in one basin.
