  • VariOx™- Jet Aerator

    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 cross flow of motive liquid through the air entering the outer nozzle creates a shearing action which generates a medium to fine air bubble. The air bubbles are entrained within the jet plume and discharged in a horizontal plane into the lower portions of the basin.

    More Information » www.parkson.com/products/variox

    VariOx™- Jet Aerator

    Parkson’s PISCES™ CFSBR is a sequencing batch reactor process which operates in a continuous fill mode. It combines the process benefits of cyclical treatment with the simplified operating concept of continuously filling all reactor tanks at all times. Flow is split evenly to all tanks utilizing a splitter box with manual valves, eliminating the need for cycling automatic valves to control influent. Anoxic and anaerobic fill conditions for filamentous control and nutrient removal are achieved during settle and decant when aeration is turned off, yet flow is still entering the reactors. An underflow baffle provides a barrier between the influent entry point and the main react zone where the decanter is located, allowing settle and decant to occur under quiescent conditions.

  • DynaSand® EcoWash®- Continuous or Intermittent Backwash Filter

    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.

    The DynaSand® EcoWash® Filter allows continuous filtration with intermittent sand washing. Operating in this mode, the system reduces the amount of reject water, increases filter performance, maximizes the airlift lifecycle, and reduces maintenance time.

    The DynaSand® EcoWash® Filter is available as either a standalone package unit or a modular concrete design.

  • Lamella® Gravity Settler (LGS) and Lamella® Gravity Settler Thickener (LGST)

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

    Inclined plate settling works by having a solid/liquid stream that has been flocculated enter a tank and flow upward between a pack of inclined plates.  The solids fall to the plate surface, where they tumble by gravity down to a sludge collection hopper. The clarified effluent flows through orifice holes and exits the top of the settler. 

    Lamella EcoFlow® is a patent-pending design change that eliminates the area of interference at the bottom of the plates and allows for full utilization of the plate settling area.  This translates to a capacity increase of 25% in the same footprint!

  • SRC & SRM Oil/Water Separator

    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 influent flow first enters an oleophilic (affinity for oil, not for water) slant-rib coalescing pack where oil droplets adhere to the ribbed pack and merge with other droplets which grow in size and rise to the liquid surface. The design of the coalescing pack and oil attracting characteristics of the media ensures the highest degree of surface contact and coalescing efficiency. Accumulated oil at the surface displaces water and begins to overflow a weir into an oil reservoir where it can either flow out by gravity or can be pumped.

    The coalescing pack also removes solids via the 55° angle of the pack’s ribs. Once oil and solids are remove...
