In the realm of wastewater treatment, the focus on nutrient removal has led to the development of diverse technologies like those below. Smart screening systems are being employed to optimize the screen field in real time, while versatile sludge dryers are capable of processing a wide range of sludge types with minimal environmental impact. Additionally, innovative dewatering containers are enhancing the process of producing drier cakes more efficiently.

Nederman MikroPul Thin Film Dryer
The Thin Film Dryer from Nederman MikroPul is a versatile sludge dryer that can process all types of sludge, including digested, undigested, and industrial sludge, as low as 10% DS. It achieves a variable sludge dryness range of 30 to 95% DS, and the dryer has been successfully utilized for various applications such as Class A, landfilling, composting, alkaline stabilization, incineration, gasification, pyrolysis, and solid fuel production. With a simple design, the dryer has a single-drive motor, requires no separate feed system, and generates less than 200 cfm of exhaust vapor, which can be easily treated. Its high-efficiency design consumes 1,150 to 1,300 Btu/lb of evaporated water and can recover up to 85% of this heat for other purposes, including digester and building heating.

Duperon FlexRake IQ 
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. During peak flow conditions, it adjusts the bar screen opening itself to provide additional hydraulic capacity and safety factor, matching the best capture rate to the flow volume in real time. 800-383-8479; www.duperon.com

Park Process SludgeKing II
The SludgeKing II roll-off dewatering container from Park Process incorporates an engineered design that eliminates trapped water in the bottom of the filter cake. The second center wall filter increases filter area by 33% producing drier cakes in less time. The plastic floor panels that cover the floor space between wall filters and center wall filters serve three purposes. They hold down the bottom of the filter elements, help eliminate standing water and aid in filter cake dumping. The inlet manifold is split into three inlets, each with a ball valve, allowing incoming flow to be distributed evenly into the three compartments formed by the two center-wall filters. 855-511-7275; www.parkprocess.com

Smith & Loveless Model R OXIGEST 
The Smith & Loveless Model R OXIGEST field-erected treatment plant achieves BOD/TSS, nutrient removal, and water reuse for flows up to 3 mgd in a single tank. Its concentric design with integral biological treatment zones eliminates expensive sludge pumps and yard piping while minimizing installation expenses, land usage and construction time. Smart automation and remote intelligence really simplify maintenance and allow for a stable operation. It integrates high performance components that offer advanced process control and automation throughout the plant’s operation, and can be managed with the QUICKMART touchscreen PLC. Multiple internal zones can be employed to provide specific activated sludge processes for stringent treatment requirements, including biological nutrient removal and water reuse. Integral treatment process steps may include flow equalization, screening and fine grit removal, anoxic zones for nitrification-denitrification, tertiary filtration, disinfection, biosolids storage, or other specialized treatment. Systems can be designed for water reuse and direct or indirect discharge. 800-898-9122; www.smithandloveless.com
