Parkson Corporation is pleased to announce the EquaReact® Biologically Enhanced Equalization Reactor (B.E.E.R.) System

EquaReact® is our unique equalized nutrient removal system that combines hydraulic flow equalization and multi-stage (anaerobic, anoxic, or aerobic) activated sludge treatment as a system offering to provide biological or enhanced nutrient removal in industrial and municipal markets. Our equalized nutrient removal system reduces land requirements, energy consumption, and capital costs while increasing the overall treatment system performance and efficiency.

Process Applications for EquaReact® 
  • Activated Sludge
  • Two Stage MLE
  • 4 Stage Bardenpho
  • 5 Stage Bardenpho
  • Membrane Bio Reactor (MBR)
  • Sequencing Batch Reactor (SBR)
  • Moving Bed Bio Reactor (MBBR)
  • Integrated Fixed Film Activated Sludge (IFAS)
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 storm water 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 equalized biological nutrient removal  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  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

NETZSCH expands grinding technology with new N.MacT Twin Shaft Grinder

NETZSCH Pumps North America, LLC, experts in solutions designed specifically for difficult pumping applications, announces the new N.MacT Twin Shaft Grinder, designed to protect pumps and processes. The N.MacT is designed to fragment a variety of materials, and is ideal for wastewater treatment, biogas and biomass plants, food, animal processing, and other waste and industrial applications. Available in both channel and inline (flanged) housing construction, the N.MacT can be installed into effluent channels or upstream from a pump.

Complementing existing NETZSCH product lines, the N.MacT expands grinding technology offerings, providing an upstream application to core NETZSCH pump technology. Featuring cartridge cutting knives for quick and simple replacement and servicing, the N.MacT offers quenched lubricated mechanical seals for dry running capability. The mechanical seal cartridge design – a leak free combination of mechanical seal and bearing cartridges – enables quick and simple replacement and servicing. For higher flow applications, grinders can operate in parallel, enabling partial servicing while in operation. The N.MacT can be mounted upstream before the pump (inline model) or on top of the auger (channel model). Grinders can also be stacked for successive particle size reduction. An optional control panel is equipped with an auto-reverse feature to retract jammed media.

The N.MacT Twin Shaft Grinder features modular assemblies and interchangeable components that facilitate universal parts servicing. Dual recessed and self-collapsing lifting tabs make pull-out for servicing simple. The flanged versions include cleanout and inspection ports. Dual tempered hex shafts are designed for pre-indexed assembly and even transfer of load. An exclusive shock absorption system guarantees quiet and trouble-free prolonged operation.

Models feature from 1 to 6 cutter cartridges per shaft. Cartridges come pre-assembled, with a worry-free pre-stacked spacers and blades and are available in different materials depending on the application. The cycloidal gearbox is maintenance-free for up to 2 years. The grinder comes standard with different cutting gear sizes for different shaft speeds, resulting in better grabbing and grinding.

Available accessories include a control panel to ensure operator and equipment safety, a cutter cartridge cleaner that keeps the area free to cut and allows fluid passage, and a transmission shaft extension that elevates the electric motor to above the fluid limit.
