Parallel Plate Vertical Clarifier

The Monroe Parallel Plate Vertical Clarifier is designed to provide low cost, efficient solids removal from a wide range of waste and process liquids. The inclined plate design allows the total gravity settling area to be as much as ten times more than the actual floor space occupied by the clarifier. Integral chemical mixing and flocculation tanks are available.

This unit is typically used to remove solids from industrial wastewater. 

Optional equipment includes skimmer, drag conveyors, chemical treatment, flocculator, thickener, and control panel.

• Parallel inclined plate upflow separator
• Efficient removal of solids from liquids
• Extremely low space requirements
• Minimum maintenance
• Low installed costs
• No moving parts in settling area
• Capacities from 1 to 2,000 GPM

Monroe also offers versatile Horizontal Clarifiers which utilize cross flow parallel plate technology capable of removing floating contaiminants as well as settleable materials.

Inclined Plate Clarifier Design

The Monroe Vertical Clarifier is designed to remove solids from wastewater and other process liquids. The Flash Mix and Flocculation Tanks (optional) allow for the addition of chemicals and polymers that will aid the settling process - adjusting pH to precipitate dissolved solids and/or enhancing the agglomeration of suspended particles into heavier, more settle-able floc. The liquid is fed from these tanks into the clarifier through the inlet chamber, which directs flow into the separation section.

The liquid then enters the lower area of the laminar plates through side slots which distribute it across the entire width of the plates. Particulate settles onto the face of the plates and slides down to the clarifier bottom. The clarified liquid exits the plate sections through weirs at the top of the unit which are designed to develop and control adequate pressure drop, maintaining laminar flow through the plates. The clarified liquid then flows into the effluent chamber and out of the clarifier.

Settled solids collect at the bottom of the pyramid sludge hopper and are removed from the clarifier. A Sludge Thickener (optional) with rake mechanism may be utilized in place of the pyramid hopper when applicable. 

Designed For Your Specific Water or Wastewater Clarifier Application

Monroe Parallel Plate Vertical Clarifiers are carefully engineered to meet the specific requirements of each application. Well proven design criteria assure maximum performance of each clarifier. The design provides for easy field installation, fast startup, and low maintenance costs.

While many installations provide adequate solids removal without influent pre-treatment, optional mixers and flocculator tanks are available to enhance efficiency when required. Some solids must be flocculated to achieve adequate mass to be effectively removed. Monroe Parallel Plate Vertical Clarifiers are manufactured in two different plate inclinations; the 45° clarifiers are designed for removal of heavy solids while the 55° clarifiers are designed for light solid removal applications.
