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.

System Design
Influent is fed into the clarifier downward through feed channels between the laminar plate sections. As the velocity of the influent decreases near the bottom of the channels, larger particulate settles to the clarifier bottom.

The influent enters the lower area of the laminar plate sections from the channels through side slots. The waste liquid is then distributed across the entire width of the plates, and flows upward under laminar flow conditions. Particulates settle onto the plates and slide down to the clarifier bottom. The liquid exits the plate sections through weirs at the top that are designed to develop adequate pressure drop to maintain balanced flow through the plates. The liquid then flows into effluent channels, and out of the clarifier.

Custom Engineered
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.

Special Features
Wide range of construction materials. Mild steel, special coatings, stainless steel, fiberglass, plastics and other materials are available to meet specific needs.

The unique, modular design of the Monroe Parallel Plate Vertical Clarifier allow easy removal of individual laminar plate modules from the clarifier for inspection.

A flash mixer and flocculator tank are available pre-treatment options.

Complete electrical controls are available to meet customer requirements.
