Oil water separator and clarifier

Clarisep: High-Rate Solids Settling and Oil Separation in a Compact Footprint

Efficiently Remove Oils, Fuels, and Settleable Solids from Wastewater. The Clarisep series from Pan America Environmental, Inc. is a family of API421-based, above-ground steel coalescing/settling oil water separators. It combines slant plate (lamella) clarification with Flopak coalescing media in a single, compact tank for superior removal of oils, fuels, petroleum-derived products, and solids.

Ideal for industrial process water, vehicle wash racks, groundwater remediation, stormwater, and more.

• Flow rates: 5–250+ GPM (custom sizes available)
• Proven performance: Reliable gravity-based separation with no moving parts in the core process
• Space-saving design: High-rate plate technology reduces footprint significantly compared to conventional separators

Key Clarisep Benefits

• Proven reliability with simple, low-maintenance operation
• Economical & durable construction: Standard A36 carbon steel (epoxy-coated); options for 304/316 stainless steel or polypropylene
• Compact footprint – saves valuable floor space
• Highly customizable – variety of plate spacings, integrated options, and configurations
• Easy to install, operate, and maintain – hopper bottom for sludge collection, no complex mechanics

How the Clarisep Works

The Clarisep integrates two powerful processes in one tank:

1. Solids Settling (Slant Plate Clarification): Wastewater flows upward through angled lamella plates. Solids contact the plate surfaces, lose velocity, and slide down into the sludge hopper for easy removal.
2. Oil & Fuel Separation (Coalescing): Water then passes horizontally through Flopak corrugated coalescing media. Oil droplets attach to the media surfaces, coalesce into larger droplets, and rise to the surface for skimming/collection.

Result: Clean effluent with significantly reduced Total Suspended Solids (TSS), oils, and greases.

Clarisep Performance & Sizing

Clarisep models are available in a range of capacities. Flow rates are typically based on 0.25 GPM/ft² surface loading (adjustable by plate spacing). Contact us for detailed sizing based on your flow rate, oil/solids content, and effluent requirements.
