HydroFlo Tech Inclined Plate Clarifiers

Follow this link for information on Hydro-Flo' "Clarifier Design Parameters"

HydroFlo Tech' line of Inclined Plate Clarifiers is engineered to remove settleable suspended solids from wastewater or process streams by the most efficient means available. A properly designed Inclined Plate Clarifier will remove these solids, allowing downstream filters or process equipment to perform as designed, as well as reducing overall operating costs and improving overall system maintainability.

Every Hydro-Flo Inclined Plate Clarifier is available with numerous plate spacing options. By altering the plate spacing (to allow for different solids loading ratios, settling rates, etc.), Hydro-Flo can make certain your clarifier is sized appropriately for your application. By combining the plate spacing options with different Inclined Plate Clarifier configurations, Hydro-Flo ends up with the largest line of clarifiers available. This allows us to solve a tremendous variety of water treatment issues, making Hydro-Flo Inclined Plate Clarifiers the most versatile systems available.

HydroFlo Tech manufactures two basic Inclined Plate Clarifier models, the LS Series (Stinger™) and the ClariMax™.

ClariMax™ Series Inclined Plate Clarifier

The ClariMax™ Inclined Plate Clarifier is designed for high flow (up to 3,000 GPM) severe duty applications. The ClariMax™ is available in four different profiles, ranging in height from 8 to16 feet tall (with the sludge thickener) and 9 to 19 feet tall (with the pyramid hopper).

HydroFlo is the only company offering both co-current and counter current technology in a single compact

clarifier package. HydroFlo has patents pending for this highly efficient Hybrid technology.

LS Series (Stinger™)
Inclined Plate Clarifier

The LS Series Inclined Plate Clarifier is designed for low flow solids sedimentation applications. It can handle flow rates up to a maximum of 200 GPM. It is a compact, cost effective clarifier suitable for most applications with solids loading ratios of less than 1,500 PPM.

We also have the capability of adding a central surface drag skimmer for the removal of floatable constituents from the waste stream. This is an exclusive HydroFlo feature, making our clarification systems the most versatile available.

This feature becomes extremely important for those who are treating a variety of waste streams with a single system. By incorporating a dissolved air flotation recycle system, the clarifier can now operate as an incredibly efficient dissolved air flotation (DAF) system. This will allow you to operate the system as a clarifier when treating "settleable" materials and as a DAF when your waste product tends to float or remain suspended in the waste stream.

LS Series (Stinger™) Inclined Plate Clarifier

Model LS-21 handles up to 35 GPM of continuous flow
(based on application)

The LS series clarifier (affectionately dubbed the "Stinger") is the finest low flow clarifier available. We have had this product on the market for 5 years, and other companies are already copying the design.

Built from the highest quality materials the "Stinger" has features usually found in much more expensive clarifiers.  For example, it comes standard with a sludge thickener (this pre-conditions the sludge prior to dewatering and also prevents maintenance issues like "rat" holing).  It also has the largest sludge storage capacity of any clarifier in its class.

The Stinger comes pre-assembled, factory tested, and is easy to install. Simple to operate and maintain, it is everything you could want in an industrial duty clarifier built to take all the abuse you can throw at it and still keep doing its job, day in and day out.

ClariMax™ model 700 in stock available for sale or lease...

This mobile clarifier features 3000 square feet of total projected surface area (2,394 effective) . This unit can handle typical process flows in the range of 500 to 850 GPM (0-1000 GPM max operating range) depending on the desired operational efficiency. This is the finest clarifier we produce and it includes all the bells and whistles.

  1. For operator access (equipment maintenance and monitoring) we have incorporated a central bridge mounted catwalk with OSHA compliant handrails and ladder.

  2. The media packs are precision machined, hand welded polypropylene for a precision fit and also, the utmost in chemical resistance. Also, the super slick surfaces presents the accumulated sludge with the lowest surface tension available allowing the sludge to easily slide off the plates.

  3. Our stainless steel trough assemblies are engineered to give our clarifiers the best possible flow distribution available in the market today. Also, as a plus, adjustment of the troughs is achieved within minutes by the use of our optional hand-wheel assembly. A quick turn of the wheel raises and lowers the trough sections making setup a snap.

  4. This clarifier comes equipped with an air sparge system to help clear solids from the plate packs prior to prolonged system shut down or equipment maintenance.

  5. Monitoring the effluent is a turbidity sensor and controller tied to the main PLC.

  6. The clarifier comes equipped with a double drop trailer, but not just any double drop. This trailer is set up with a custom air bag system that allows you to set the trailer directly on the ground. All you have to do is position the clarifier where you want it, blow the air from the airbags and the clarifier will set right down on the ground. No cranes, no heavy equipment, no fuss, just drop this trailer where you want to treat and you are ready to go.

  7. This clarifier can travel anywhere, any day, anytime without any permit requirements. That's right, this is the largest mobile clarifier package available that travels anywhere without over size load permits. Hook it up anytime (day or night) and haul it to your customers site an a moments notice. You can be up and operating within hours of arriving at your customers site.

As with the clarifier, the pump systems and controls are the finest available. The influent pump package features variable speed progressive cavity pumps that will gently process the influent flows without causing damage to the flocculated influent stream. These pump controls can be tied into your overall PLC control system to proportionally feed the clarifier influent as needed. The sludge pump package is also a variable speed progressive cavity pump of the same type and manufacture as the influent systems to keep spare parts to a minimum. This sludge pump can also be tied back to your systems overall PLC systems to make the sludge transfer a snap. Whether you are feeding directly to a filter press, a centrifuge or any other type of sludge dewatering device, this pump system will handle the demand without blinking an eye. The flow meters and sensors used are top notch industrial duty devices that are designed to operate under the harshest of environments.

HydroFlo's ClariMax™continues to evolve...

Working with contractors, engineers and plant operators, the staff at HydroFlo constantly strives to improve the design of our products in order to improve overall operation efficiency, installation, and maintenance. We have developed a new "effluent trough / truss" design to improve flow distribution as well as the overall stability of our equipment when installed in seismic and hurricane zones. We have improved our thickener design by converting to a double helix sludge auger / thickener design that improves overall thickening and eliminates any "dead" spots as well as "rat holing". The horizontal design gently turns the sludge over in the hopper giving the water a ready escape path to the surface, greatly improving clarifier sludge pre-conditioning. Other structural improvements include a heavier clarifier upper girdle section, heavier base plate sections, a new lifting lug design, and a tubular "flow through" truss system for the support of the plate packs.

Hyperion picks HydroFlo as supplier of clarifiers
for their mobile oil/gas manufactured water treatment system...

The clarifier is one of the key components used for the treatment of manufactured water in the oil and gas industry. Used for the efficient removal of suspended solids prior to water reuse, HydroFlo's clarifier is ideal for this application. When Hyperion landed their design/build contract, they knew their customer needed a clarifier that would perform well regardless of the makeup of the water being treated. Knowing that they needed a clarifier capable of providing uncompromising results, they came to HydroFlo for a solution.

The clarifier was designed, fabricated, assembled and shipped ahead of schedule. They are now looking to us to supply other treatment components for the system as it's functionality expands in the future

Schnitzer Steel picks the ClariMax™as the preferred device for solving site run-off issues...

We are happy to announce that Schnitzer Steel has picked HydroFlo as the manufacturer of the clarifier for their new plant expansion. There was a great deal of competition over this contract, but HydroFlo's superior design and customer support won the day.

HydroFlo worked long and hard with the engineers and general contractors supplying them with design data and documentation, as well as 3D models and other engineering support to make sure that the design would integrate seamlessly with the other process equipment required at the site.

HydroFlo lands Hecla project...

HydroFlo was picked as the clarifier supplier for this project for a number of reasons. While it is true that they liked the ClariMax's™ advanced features and design, our ability to customize the unit specifically for their facility played a large part in choosing HydroFlo as a supplier. Our horizontal thickener auger assembly was one of the features that allowed us to meet their very stringent site specific requirements.

HydroFlo chosen as supplier to Harris Mechanical...

HydroFlo's help in the overall planning of this facility proved to be indispensible during the initial design phase. Our engineers provided 3D models to the customer and reconfigured our equipment to meet all the ancillary plumbing and structural issues. Our recommendations saved them thousands of dollars in structure reconfiguration issues and also allowed them to incorporate the structure of the clarification system into the walkway and platform support system. The clarifier dropped right into place and integrated seamlessly with all the other structural elements of the project.

The HydroFlo Stinger™ sells worldwide...

These small full feature clarifiers have been finding their way into small manufacturing facilities worldwide. Their high efficiency and small size allow small producers to meet their discharge requirements. As an additional bonus, the Stinger™comes standard with a sludge thickener. HydroFlo is the only manufacture to offer this feature in this class of clarifier.

Bench scale Stinger™ is a hit with chemical manufacturers and major universities...

HydroFlo has been supplying specially built Stinger™ style clarifiers for use at laboratories and major universities. These small scale units duplicate the full scale operating environment that will be seen in a fully functioning system. This allows chemical manufacturers to fine tune chemical formulas at their facilities instead of trial and error in the field. Also, use by students at the university level allow them see units in actual operation and solve industry specific treatability issues.
