Biological Systems

Clarification – Segmented, Spiral Blade, Header, Suction Pipe, Thickeners, Solids Contact, Drives, Clearflow Jet/SBR – ClearStream

ClearStream offers a complete line of sedimentation equipment for most water, wastewater, and industrial applications including Jet Aeration and SBR systems. ClearStream utilizes cutting edge analysis and design technologies to custom design each piece of process equipment to meet each individual customer’s needs.

Trickling Filter Media

Brentwood Brentwood Trickling Filter Media is a structured-sheet media that is largely responsible for the success of performing trickling filters. Unlike outdated rock fill, PVC modules have superior compressive strength and higher void volumes, which are necessary for stacking. 

Fine Bubble Membrane Disc Diffusers – Evoqua: Envirex

Evoqua: Envirex- Diamond S Membrane Disc Diffusers is more efficient than a typical 9″ diameter diffuser, resulting in better performance and lower energy costs. The proprietary diamond punch pattern provides 10% more slits than a typical membrane, allowing more fine bubbles to be produced.

Oxidation Ditch – Diffused Aeration with Flygt Banana Blade Mixers

Fine Bubble Diffusers with Flygt Banana Blade Mixers Combines the high rate transfer of diffused aeration, with submersible mixing to provide biological oxidation ditch for both new and retrofit applications. 

Magnetite Ballasted Biological System – BioMag

Retrofit Existing or New

Evoqua BioMag – Ballasted biological process to allow WWTP to handle 3x flow and solids loadings, and to operate at longer sludge ages to achieve enhanced nutrient removal, without physically adding tankage to the plant. 

Ballasted Clarification

CoMag for Enhanced Primary or Tertiary

Evoqua – CoMag is a high rate clarification process utilizing internal recycling of settled solids and small amount of Magnetite (non-abrasive, high specific gravity) for floc formation to allow for less chemical use and footprints up to 20x smaller than conventional clarification. 

Oxidation Ditch – Orbal and VLR

Simultaneous nit/denite

Evoqua – Oxidation Ditch is a modified activated sludge biological treatment process that utilizes long solids retention times (SRTs) to remove biodegradable organics. Orbal® system with a Concentric Loop™ configuration that creates dedicated zones for specific treatment processes. 

AEROBIC GRANULAR SLUDGE – AquaNereda – Aqua Aerobics

AEROBIC GRANULAR SLUDGE – AquaNereda – Aqua Aerobics- Aerobic granular sludge is an advanced biological wastewater treatment technology providing Enhanced Biological Nutrient Removal (ENR) with TN <3 mg/l and TP<1.0 mg/l without chemicals.

Complete Mix Activated Sludge with FERMENTER – AquaPASS

Pre and Post Selector Basins with Fermenter for Bio-P & Denitrification optimization

Aqua Aerobic Systems – AquaPASS process incorporates selector basins both anaerobic and post anoxic with a fermenter to produce VFAs to aid in formation of Phosphorus accumulating organisms. Equivalent to 5 stage with a RAS concentrator . Available with both fixed diffusers or retrievable diffusers where it is possible to promote single or multiple basins. 

Complete Mix Activated Sludge – MixAir -Retrievable Diffusers w Mixer

Simultaneous Nit/Denit

Aqua Aerobic Systems – MixAir is a biological system that allows a single aeration basin to be used since its aeration and mixing is accessible above the water surface. 

Oxidation Ditch – Tri-Oval

Aeration Industries -Tri-Oval Oxidation Ditch provides superior wastewater treatment process control and design flexibility of the activated sludge process. Couple this with the cost savings benefits of lower construction, easy installation, and low maintenance — you have a winner in water treatment.


Kubota Membrane USA Corporation is an MBR system supplier based on the Kubota Submerged Membrane Unit® (SMU). The Kubota SMU was pioneered to treat municipal, commercial and industrial wastewater simply and successfully. 

AquaSBR – Aqua Aerobics

Aqua Aerobic Systems SBR Aqua Aerobic Systems AquaSBR® Sequencing Batch Reactor provides true batch reactor technology with all phases of treatment accomplished in a single reactor. 



Aqua Aerobics – Retreivable Aeration – The system features fine-bubble “Retrievable Diffusers” in racks that can be lifted by a davit crane and rotated outside the basin for maintenance or replacement without taking the aerations system offline.


Aeration Industries – Aire-O2 Aspirator  This surface aerator creates a vacuum drawing air down the shaft into the water.  The rotating propeller forces water outward horizontally past the end of the shaft at high velocity. 

Surface Aerator – Aqua-Lator

Evoqua – The Aqua-Lator® surface aerator, introduced in 1963, is considered the first floating mechanical aerator for wastewater treatment applications. The powerful pumping action of the surface aerator transfers oxygen by breaking up the wastewater into a spray of particles, creating more surface area for atmospheric pressure to drive oxygen into the wastewater.
