Sand-oil catchers – the equipment is designed for the mechanical cleaning and collecting of suspended solids and dissolved contaminants that contain waste oil and oils.

The principle of operation – gravitational separation of different density materials : heavy matter sinks, lighter materials float to the surface.

Scope – car parks, parking lots, gas stations, viaducts, industrial & built-up areas.

The complex cleaning equipment consists of two units – sand separators and oil catchers are arranged in a series and combined into a single body.

High purification efficiency of suspended solids and oil products is achieved through the use of two types of thin-film modules.

  1. Thin-film module to separate suspended
  2. Thin-film module with a coalescing effect used for trapping petroleum.

At first, thin-film modules reduce the required parameters supplied to the flow rate, thus setting and stabilizing the hydrodynamic characteristics. This provides a significant reduction in the of size of the plant without reducing efficiency compared to conventional technologies which use gravitational settling and filtering through the porous elements.

Thin-film modules are made of PVC profiles. Module design provides high mechanical strength and allows efficient use of the internal volume settings, to place the necessary technological elements.

To achieve purification reset parameters in fishery reservoirs, sorbents are used.

Purification of the oils and sand traps is carried out using a disposal machine via the maintenance shaft of the oil catching trap.

The plant structures are made of a helically twisted steel pipe with a double polymer coating, or of helically twisted plastic tube.

Petroleumcatchers (oil traps) are made based on standard treatment parameters or with specifically designed parameters.

Petroleumcatchers (oil traps) are delivered in full operational readiness and come equipped with hatches, anchor straps, sealing gaskets and technical wells intended for access and service facilities.

For the selection of the equipment, it is necessary to fill in a questionnaire posted on the website.
