Low cost oil/grease separator

A method of assembly of a modular oil/grease removal assembly comprising:

• installing a container for receiving and holding effluent water containing oil/grease to be removed from the effluent water and having sectional covers;
• mounting a main sectional cover that has two pair of opposite sides with one pair of opposite sides adapted to engage the container for support of the main sectional cover by the container and the other pair of opposite sides having flanges extending downwardly and laterally with a further extension downwardly to provide rigidity and that supports a rotatable disk for partial immersion within effluent water in the container and in contact with the oil/grease, a drive in driving engagement to provide rotation of the disk when the drive is engaged;
• a trough mounted on the main sectional cover in engaging relation to opposite sides of the rotatable disk, a scraper blade mounted on the trough so that the scraper blade extends from the trough into sliding engagement with a side of the disk, the disk, scraper blade and trough cooperatively disposed and structured to direct oil and grease from the disk along the scraper blade along the trough for collection in a storage container and an electrical resistance heater that extends downwardly into the container so as to have an operable portion of the heater at least partially immersed within the body of effluent water to cause the oil/grease to be in liquid form, electrical controls for selectively operating the drive and the heater,
• mounting additional sectional covers that have four sides with two opposite sides adapted to engage the container for support of the additional sectional cover by the container and one of two opposite sides adapted to engage and seal to the main section.
