Circular Clarifiers

Monroe Circular Clarifiers use widely accepted settling technology based on the density difference between water and suspended solids. The Monroe Clarifier is designed to give you the performance you require with long-term reliability.

Monroe Environmental realizes that all waste streams are not alike and in many cases standard designs must be modified. Tank sizing, influent and effluent arrangements, flocculation requirements, sludge removal and skimming methods and mechanisms are some of the considerations necessary for a successful installation.

The Monroe Clarifiers are available in self-supporting prefabricated steel units or they can be designed to drop into a concrete tank. Existing structures and systems can sometimes be utilized and upgraded for cost savings. Circular Clarifiers normally use either a center feed inlet well or a peripheral inlet. The center feed well design can be equipped with a chemical addition system with mixing and flocculation. With the center feed well, the effluent is discharged along the outer wall of the clarifier tank. Clarifiers with peripheral inlets will be designed with a center bottom liquid outlet.

Monroe Environmental builds primary and secondary clarifiers for municipal wastewater treatment, as well as flocculating clarifiers and solids contact clarifiers for clean water purification. Our experienced staff will provide high efficiency, low maintenance systems that will provide the highest return on investment.

Primary Wastewater Treatment Clarifiers

Monroe Environmental's primary circular clarifiers are designed to receive raw wastewater after it has been pre-screened to remove large objects and grit. This primary sedimentation tank will produce a homogeneous liquid capable of being treated biologically and a sludge that can be separately treated or processed. Monroe Environmental incorporates durable drives and bottom scraping rakes that will continuously remove settled sludge. The rake employs multiple bottom scraping blades that are angled to ensure that all settling sludge is captured and brought to the central sludge well. Floating matter in primary wastewater clarifiers includes grease, oils, leaves, and plastics.

Secondary Wastewater Treatment Clarifiers

Monroe Environmental's secondary circular clarifiers for wastewater are designed to provide a high quality effluent suitable for discharge to the environment or further treatment. The Monroe Environmental secondary clarifier effectively separates the biological floc and colloidal solids to produce wastewater with very low levels of organic material and suspended matter.
