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. These unique elements are woven together on stainless steel shafts to form the endless moving belt that collects, conveys and ultimately discharges the solids that are being removed from the treated wastewater. The Aqua Guard is capable of performing in a wide range of applications and element spacing settings – from 1mm to 30mm –depending on the requirements of the specific treatment process.

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® bar/filter 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 new Aqua Guard UltraClean screen outperformed the standard Aqua Guard screen in side-by-side capture rate tests by over 50%. The new upper UltraClean “head” design makes the Aqua Guard UltraClean superior and it is available for new units or can be rebuilt on existing ones.  The Aqua Guard® UltraClean™ screen, a self-cleaning in-channel screening device, utilizes a unique filter element system designed to automatically remove solids larger than element spacing. Aqua Guard® screen filter elements form an underwater grid that ensures better capture rates when compared to rake bar screens that utilize only vertical bars for screening. A specific configuration of filter elements is mounted on a series of parallel shafts to form an endless moving belt that collects, conveys and discharges solids for further processing or disposal.

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 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 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 ¼” 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. Operation of the spiral is based on level control upstream of the screen basket.  Screened solids are conveyed out of the channel, dewatered and discharged into a dumpster or conveyor.Units are available in a tank when a channel is not available. A common in-tank option to pre-treat septage (with special controls) prior to being accepted in a wastewater treatment plant.

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 Helicon conveyor is totally enclosed. Bolt-on covers contain odors, keep extraneous materials out, eliminate spills and minimize housekeeping. The Helicon’s shaftless spiral design is extremely simple, uncomplicated and will provide years of trouble-free performance. The shaftless spiral provides clear, unrestricted throughput with no center shaft to snag or wrap solids. There are no intermediate hanger bearings to obstruct flow and no maintenance-intensive end bearings.
