Because every site and application is different, our systems are custom designed to meet the footprint, water quality, energy demands, and aesthetic requirements for each of our clients. From the urban city center to industrial manufacturing plants, our suite of natural and engineered treatment solutions deliver the most sustainable and impactful water management solution for any site.

 

 

Waste water mining system

Wastewater Mining Systems

NextEra Distributed Water designs wastewater mining systems that extract wastewater from existing sewer systems for decentralized reclamation and reuse. These systems work in concert with municipal conveyance infrastructure and often provide benefits to the existing sewer network by relieving capacity constraints and minimizing the occurrence of down-stream combined sewer overflows. Mining systems are typically below grade and can integrate seamlessly into any project landscape or hardscape.

 

 

Screening

Screening

Primary screening is the first step in the wastewater reclamation process. NextEra Distributed Water uses advanced screening systems, like rotating belt filters and micro strainers, to ensure efficient and automated solids removal, compaction, washing, and disposal. Our primary screening approach is customized to the needs of each treatment application, and our enclosed odor-free designs have been proven in densely populated, urban environments.

 

 

Equalization Systems

Equalization Systems

Primary Equalization (EQ)Equalization (EQ) is often an important component of successful reuse systems , buffering variability in influent flow and concentration. NextEra Distributed Water draws upon extensive experience sizing EQ systems to fit virtually any commercial, industrial, or municipal wastewater source.

NextEra Distributed Water utilizes a variety of biological treatment technologies depending on wastewater characteristics and project specific goals. Often reactors are combined in the process design with complementary biological or ecological reactors to increase overall system efficiency and resiliency. A few of these include:

Moving-Bed Bioreactors (MBBR)

Moving-Bed Bioreactors (MBBR)

Moving-Bed Bioreactors (MBBRs) utilize attached growth media as a substrate for the formation of treatment biofilms. This media is circulated in aerated treatment reactors ensuring excellent oxygen and substrate transfer to the biomass. Due to the high surface area and surface charge of the media and the robust microbiological communities, MBBRs are ideally suited for high-strength, industrial wastewater applications. In existing wastewater plants, the addition of moving media can expand treatment capacity and improve effluent quality without incurring additional footprint.

 

 

Submerged Fixed Film Reactors (SFFR)

Submerged Fixed Film Reactors (SFFR)

In contrast to MBBRs, Submerged Fixed Film Reactors (SFFRs) utilize stationary media in aerated wastewater reactors to improve treatment efficiency. The additional surface area provided by SFFR helps reduce footprint and improve effluent quality by increasing system biology. Submerged fixed film media can be deployed in reactors where moving media is difficult to contain.

 

 

 

Membrane Bioreactors (MBR)

Membrane Bioreactors (MBR)

MEMBRANE BIOREACTORS (MBR)Membrane Bioreactors (MBRs) increase treatment capacity by increasing the concentration of suspended microbiological communities, in contrast to MBBRs and SFFRs where attached biofilm communities are increased. Submerged membranes contained within the final biological treatment reactors are utilized to efficiently remove solids from the treated effluent despite the high suspended solids concentrations. These systems produce a high-quality effluent suitable for reuse and have a compact footprint.

Inspired by nature, NextEra Distributed Water specializes in the application of ecological treatment technologies. Mimicking what nature has done for billions of years helps us improve water quality, lower system energy demands, and create wastewater treatment solutions that can serve as a centerpiece of our communities.

Hydroponic Reactors

Hydroponic Reactors

Hydroponic reactors utilize plant racks suspended over aerated wastewater tanks to provide substrate for treatment microorganisms. NextEra Distributed Water has developed a palette of plant species that naturally grow long roots in this wastewater environment. The roots provide surface area and supplemental oxygen for treatment biofilms. Our research has found that plant roots provide more surface area per cubic meter than synthetic media typically found in MBBRs.

 

 

 

Reciprocating Wetlands (ReCip®)

Patented by the Tennessee Valley Authority (TVA), ReCip was the first fill-and-drain wetland treatment system. These systems are attractive, odor-free, and low-maintenance systems capable of producing reuse water quality in a very compact footprint. Due to the patented fill-and-drain aeration process ReCip systems are among the most energy efficient wastewater treatment systems. These systems can be adapted to nearly any site – urban or rural. System designs have ranged between 1,000 and 300,000 gallons per day.

 

 

Polishing and disinfection steps are required to protect human health and critical process equipment from potential pathogens and elevated levels of minerals in the reclaimed water. NextEra Distributed Water employs water polishing and disinfection systems that are designed to meet client end use water quality demands.


Ultraviolet (UV) Disinfection Systems

Ultraviolet (UV) Disinfection Systems

Ultraviolet (UV) Disinfection SystemsUltraviolet (UV) disinfection utilizes high frequency light in the UV-C spectrum to denature the DNA of potential pathogens. Properly designed UV systems kill 99.99% of bacteria and viruses in reclaimed water. NextEra Distributed Water typically uses UV as a primary disinfection method coupled with chlorine to provide a disinfection residual for reuse storage and distribution systems. Dual disinfection with online instrumentation for turbidity, UV dose, and chlorine residual assures reclaimed water is always safe for reuse.

 

 

Reverse Osmosis (RO) & Capacitive Deionization (CapDI)

REVERSE OSMOSIS (RO)Depending on wastewater source and reuse equipment, mineral elements in the reclaimed water may need to be reduced to optimize reuse for boilers and other process equipment. Reverse Osmosis (RO) and Capacitive Deionization (CapDI) membranes can be utilized to efficiently remove dissolved salts from reclaimed water. NextEra Distributed Water has extensive experience with a variety of water polishing techniques and we work with leading equipment vendors to select the best technology for our projects.
