Parkson’s PISCES™ CFSBR combines the process benefits of cyclical treatment with the simplified operating concept of continuously filling all reactor tanks at all times.

The Aqua Caiman® Vertical screen allows our proven in-channel articulating rake screen to be used in locations requiring very steep or vertical mounting, or where additional rake engagement force for removing solids from the bar rack is desired. This mounting option can benefit clients with tight channel requirements in new or existing locations.

The Aqua Caiman® HD screen is designed for larger in-channel installations requiring the handling of high flows or heavy solids. It incorporates the proven features and benefits of the original Aqua Caiman® articulating rake screen, but is larger, heavier and made for the toughest applications that require jam-free operation, low maintenance and low headloss.

The IGNITE™ Integrated Nitrification process is a non-activated sludge solution for upgrading lagoon based treatment plants to achieve improved BOD and ammonia removal. The process utilizes a combination of Parkson’s Biofuser® lagoon aeration system and the TumbleOx™ Nitrification Reactor process.

The Parkson TumbleOx™ Bioreactor consists of a treatment tank(s) containing a series of slowly rotating drums. Each drum is partially filled with loose media which freely tumbles inside the five-foot diameter drum as it rotates. A thin biofilm grows on the media and provides biological treatment. The unique media design maximizes surface area for biological growth and also aerates the wastewater as the drum turns, providing dissolved oxygen for the micro-organisms. The system components include the rotating drum, plastic media, and the bearings and simple drive mechanism to slowly rotate the drum. No supplemental aeration system is required.

The Aqua Caiman® represents the next generation of articulating rake screen. In designing the screen, Parkson combined over 40 years of experience working on thousands of in-channel screen installations with in-depth market and engineering research. This allowed us to better understand the weaknesses of existing multi-rake and articulating rake screens. Our engineers put design expertise into components where strength matters the most — frame, bars and chain. They also provided a smart design to reduce manufacturing costs. The result is the most competitively priced articulating rake screen that provides unmatched durability, ease of operation and protection of downstream process equipment.

The Aqua Guard® is a rugged and proven self-cleaning in-channel screen that uses a unique filter element system designed to automatically remove a wide range of floating and suspended solids from a wastewater stream.

The Aqua Guard® PF screen is a self-cleaning, in-channel screening device that utilizes perforated plate media to automatically remove a wide range of solids from wastewater. The screen design is built on the Aqua Guard® filter element screen chassis that has been proven successful with over a thousand units installed and in operation. The Aqua Guard PF can be made with the heavy-duty “S” chain or the standard duty chain.

The Aqua Guard® UltraClean™ represents the next generation of in-channel fine screening, outperforming the original design in side-by-side capture rate tests by over 50%. This superior performance comes from a series of patent-pending improvements in the “head” of the Aqua Guard® UltraClean™ screen, each drawn from over 30 years of experience with the classic Aqua Guard® platform. Designed with the operator in mind, the Aqua Guard® UltraClean™ also offers easier access to key areas of the screen such as the brush, which has been reengineered to reduce routine maintenance by up to 75% over the original version. The Aqua Guard® UltraClean™ technology is available both on new screens, and as a new “head” retrofit for existing Aqua Guard® element screens.

The Aqua Rhino™  represents the next generation step screen, providing unmatched durability, ease of operation and ultimate protection for your downstream process equipment. 

The Aqua WashPress® can economically and effectively wash and dewater screenings from in channel and rotating screens in a variety of applications. The Aqua WashPress® will lower hauling and disposal costs by reducing weight and volume of screenings. Organics and biosolids are commonly caught along with the appropriately screened solids. If not removed, these items retain water, inhibit drainage, emit odors and result in excessive disposal costs.

The Biolac® System is a well-accepted biological wastewater treatment process with over 30 years of experience and hundreds of successful installations treating municipal and industrial wastewater. Using an innovative long sludge age, activated sludge process, the Biolac® System provides an extremely simple and cost-effective solution for many treatment applications.

Parkson offers two options for liquid removal from water and wastewater basins: effluent and supernatant decanters.  The Parkson DynaCanter™ is a floating style decanter used to remove treated effluent or supernatant from the upper portion of the basin.  The decanter utilizes a flex joint to allow vertical articulation as water levels move between high and low water levels.  The decanter collects water from below the surface to preclude foam, scum, or other floatables from the effluent.  A standard open / close valve is used in the effluent piping to control flow rate through the decanter.  No electro-mechanical components are used inside the basin making operation and maintenance convenient for the operator. 

The Parkson DynaSand® EcoWash® Filter is a unique system that filters liquid suspensions to the designed effluent quality, while at the same time cleaning the sand bed so the filter is not shut down during the backwash time. Feed water is passed upwards through the sand bed and exits the top of the filter as clean water. At the same time, sand can be removed from the bottom, cleaned and returned to the top.  A small portion of the filtered water is used to wash the sand and leaves the filter as a reject stream.

EquaCel® is a unique Wastewater Pretreatment process that utilizes the Parkson EquaReact® process along with Dissolved Air Floatation (DAF) technology as a system offering to achieve both hydraulic flow equalization and high efficiency soluble BOD and ammonia removal for Industrial wastewater pretreatment.

The EcoCycle SBR™ from Parkson combines industry leading DynaPhase Control™ technology with high efficiency treatment schemes designed to provide reliable and flexible performance for today’s stringent effluent needs.  The EcoCycle SBR™ is a true-batch SBR design, which allows for an ideal anaerobic / anoxic fill period, perfect for biological phosphorus removal and Nitrogen removal.  The true-batch design will also allow for a perfect quiescent settling step, promoting ideal sludge settling and compaction before the decant of the treated effluent.  In the EcoCycle SBR™ basin designs are not limited by basin geometry or configuration.  Deep tank SBR basins are encouraged for better O2 transfer, which can lead to reduced operating expenses. 

EquaJet is a unique Wastewater Treatment process that utilizes the Parkson Jet System and multi-stage Activated Sludge treatment as a system offering.

EquaReact® is a unique wastewater treatment process 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 both Industrial and Municipal markets. The EquaReact® System reduces land requirements, energy consumption, and capital costs while increasing the overall treatment system performance and efficiency.

The Parkson Helisieve® In-Channel Fine Screen combines fine screening, conveying and dewatering to create a highly economical system that produces screenings dry enough to take to a landfill without the need of an additional dewatering press. Screen openings are available in the standard 1/4” perforations or optional 1/8”. The heart of the system is a shaftless spiral with a brush in the screen basket area to keep the screen clean.

Hydroscreen offers proven and reliable performance in liquid/solid separation for municipal and industrial applications, particularly for screening fibrous and non-greasy solids. There are no moving parts, motors, or complicated connections. The Hydroscreen is economical and simple to operate.

With more than 1,000 installations, Rotoshear® is a proven high-capacity fine screening technology for municipal wastewater treatment plants and many industries for various applications.

Rotating drum screens with perforated plate screen media are the most successful solution for screening prior to an MBR system. Because Rotoshear® PF uses Rotoshear®’s base structure, it is the most reliable and highest capacity screen for an MBR plant.

Introduced over 25 years ago, the Rotostrainer® screen is the original self-cleaning wedgewire screen. With over 700 installations, it is a proven fine screening technology for municipal wastewater treatment plants and many industries with several application capabilities.

The HiOx® Messner® Aeration Panel provides the most efficient areation system solutions to our clients.

The Hypress® Dewatering Press is a reliable performer that dewaters and compresses coarse and fine screenings up to 35% dry weight, depending on the material. It reduces volume as much as 75% to minimize hauling and landfill costs. The Hypress unit is rugged, durable and fabricated of corrosion-resistant 304L stainless. It comes with a drain pan that collects water pressed from the screenings.

The Helicon® spiral conveyor is the answer for efficient, reliable automatic transport. The conveyor is frequently used in conjunction with other Hycor® equipment to create a solids management system that conveys the screened solids to washing or dewatering, and ultimately to disposal.

The Helixpress® unit is the cost-effective solution for dewatering the screenings collected by any type of screen. It is an all-in-one conveyor, compactor and dewaterer. It utilizes a combination of drainage, compaction and dewatering to reduce weight and volume and ultimately decrease hauling and disposal costs.

The Lamella® is the original inclined plate gravity settler. Introduced by Parkson in 1971, it has been the industry standard for this technology.

Parkson’s Model SRC and SRM Oil/Water Separators offer a reliable, compact, and economical solution to a wide array of oil/water separation applications. The Oil/Water Separators remove free, non-emulsified oil and settleable solids to produce an effluent with less than 10 mg/l of oil droplets 20 micron or larger.

The RetrievOx™ aeration system is an aeration device utilized in numerous wastewater treatment applications, including biological processes, sludge digestion, holding tanks and post aeration. Each RetrievOx™ assembly consists of a grid of tubular fine bubble diffusers, guide track, and hoisting mechanism. The grids are located around the perimeter of the tank for access from walkways or work platforms. A portable electric winch is utilized to raise the diffuser grid to the top of the tank where it is accessible by plant staff for inspection, cleaning and replacement of diffusers. 

The ThickTech™ Rotary Drum Thickener (RDT) is the industry leading sludge thickener. Its performance is unmatched, with sludge volume reduction of 90% and a 98% capture rate. In addition, this superior performance is achieved with very low amounts of polymer. The ThickTech™ system is quite compact and requires less floor space than other thickeners. It has low requirements for horsepower, water consumption and polymer usage, resulting in valuable operational efficiencies.

The VariOx™ jet aeration system is an aeration and mixing device used in numerous water and wastewater treatment applications. Jet aeration combines many of the benefits and efficiencies of both mechanical and diffused air type systems. The jet aerator consists of an inner liquid nozzle and an outer air nozzle. Liquid from the basin is re-circulated through a jet motive pump and discharged through the inner liquid nozzle at a high velocity. Concurrently, air is fed into the outer air nozzle where it is mixed with the motive liquid and discharged as a high energy jet plume.


The Continuously Sequencing Reactor is a Biological Nutrient Removal (BNR) system utilizing continuous flow in a single basin. It sequences through the 3 process phases required for BNR – Oxic, Anoxic and Anaerobic – in one basin. The 3 phases do not occur at the same time in the basin. They occur sequentially – one after the other, repetitively, over time. During the Oxic phase, the entire basin is Oxic (i.e. aerobic).
