Heavy Equipment Pre-Wash Systems

pre-wash systemClarifier / Separator Model

Operations

The Clarifier/Separator (CS) Model shall be a special purpose prefabricated inclined plate clarifier and parallel corrugated plate gravity displacement type oil/solids/water separators designed to remove free and dispersed non-emulsifed oil and suspended solids in heavy solids applications.

Inlet Compartment

The inlet chamber will be comprised of a non-clog diffuser pipe to distribute the flow across the width of the CS chamber. The inlet compartment shall be of sufficient volume to effectively reduce influent suspended solids, dissipate energy and begin separation. The inclined plates will sit elevated on top of the sludge chamber. As the water moves upwards the suspended particles have their upwards velocity interrupted by the inclined plates. These particles drop down and slide down the inclined plates and join larger previously settled particles in the sludge hopper. The sludge compartment will be provided to retain sellable solids.

Separation Chamber

The separation chamber will contain HD Q-PAC Coalescing Plates containing a minimum of 132 square feet per cubic foot of effective coalescing area. The plates needle like elements shall be at 90 degrees to the horizontal or longitudinal axis of the separator. Spacing between these elements shall be spaced 3/16" apart for the removal of a minimum of 99.9% of free droplets of oil 20 micron in size or greater. The elements are positioned to create an angle of repose of 90 degrees to facilitate the removal of suspended solids that may tend to build up on the coalescing surface, which would increase velocities to the point of discharging an unacceptable effluent. Laminar flow with a Reynolds Number of less than 500 at a maximum design flow rate shall be maintained throughout the separator packed bed including entrance and exit so as to prevent re-entrainment of oils with water. Flow through the polypropylene coalescing plates shall be crossflow perpendicular to the vertical plate elements such that all 132 square feet/cubic foot of coalescing area is available for contact with rising oil. The plates shall have a minimum of 87% void volume to facilitate removal of oil and dirt particles.

Baffles

An oil retention & underflow weir, and adjustable overflow weir will be provided in the separation chamber. The underflow weir will be positioned to prevent resuspension of settled solids.

Oil Skimmer

The clarifier compartment and the oil separation compartment will be provided with an adjustable rotatable pipe skimmer for gravity decanting of the separated oil to a product storage tank.

Clean Water Chamber

The separator will be provided with a clear water chamber which allows for gravity or pumped flow through the clean water port.

Covers

The separator is provided with a vapor tight cover that can easily be removed for service and maintenance.
