DUPERON FLEXRAKE IQ PLATFORM
The Duperon FlexRake IQ platform provides real-time smart screening for maximum resilience at the headworks. It tackles high peaking factors due to extreme weather and difficult debris like flushable wipes, first flushes and settled solids. This is accomplished by system improvements and a sequence of operations that automatically responds in real time to optimize the screen field. The reimagined design focuses on smart enhancements to the raking device to manage heavy solids loading events with four times increased debris removal capacity, improved grit and rock handling and greater solids capture. 800-383-8479; www.duperon.com
MARMON INDUSTRIAL WATER GRAVER POWDEX
The Graver Powdex precoat filter demineralizer system from Marmon Industrial Water removes both suspended solids and ionic contaminants in a single compact unit. These proven high-performance systems are customized to any power plant design and quickly achieve target chemistry for fast online operation. For industrial applications, it is used to maintain proper quality of water by removing impurities from return condensate for both water reuse and energy recovery. Treatment safeguards high-value plant assets by reducing damage and downtime, stabilizing steam cycle chemistry, and minimizes corrosion product transport, resulting in optimized operations. In addition, since condensate is returned to an ultrapure level, this reduces the need for fresh make up process water and respective generation costs. 908-516-1400; https://graver.com
VALMET FLOW CONTROL FLOWROX FINFLEX CHECK VALVES
Flowrox FinFlex Check Valves from Valmet Flow Control help prevent sewage overflow, malodors and backflow of waterways. The cover and sleeve are designed to easily slip in to the existing pipe and are affixed to a pipe with heavy-duty stainless steel expandable clamps. They can be installed in either a vertical or horizontal application. They have a very low headloss and cracking pressures. This type of check valve uses a rubber flap that is molded internally to its thick rubber housing, which allows the valve to be completely closed until a small water column discharges via gravity through the valve, and allows the runoff to occur until backpressure exceeds the inlet pressure. The rubber flap is manufactured to reduce headloss across the valve when compared to other designs such as a swing or ball check valve. When used for odor control, the valve will seal completely on itself compared to the duckbill styles that rely on increased backpressures to seal the duckbill lips closed. The check valve ranges in size from 3 to 72 inches, with backpressures up to 50 feet. 410-636-2250; www.valmet.com

EVOQUA WATER TECHNOLOGIES OSTARA PEARL
The Ostara Pearl system from Evoqua Water Technologies is a fluidized bed reactor that harvests nutrients from wastewater and transforms them into an eco-friendly fertilizer. This nutrient recovery solution converts wastewater treatment plants into true resource recovery facilities. The system is a fully customizable and modular treatment solution designed to recover phosphorus from pre-and post-digestion liquors, as well as industrial streams, through the controlled precipitation of crystalline struvite. Within the system reactor, the growth of struvite (magnesium ammonium phosphate) is facilitated by the addition of magnesium in a controlled pH setting. This allows nutrients to crystallize into highly pure fertilizer granules, which are harvested, dried and then distributed and sold as Crystal Green Fertilizer. Treated effluent is then discharged from the top of the reactor and returned to the plant with significantly reduced nutrient content. 800-466-7873; www.evoqua.com
