If stormwater needs to be discharge into fisheries or similar bodies of water, filters can be installed that work with deep sorption purification.

Sand-oil catchers are equipped sorption filters for deep cleaning. They are designed for mechanical cleaning and collecting of suspended solids as well as undissolved impurities and waste petroleum oils.

The principle of operation – gravitational separation of different density materials : heavy matter sinks, lighter materials float to the surface. Furthermore, the drain is also cleaned from insoluble materials.

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

Sand-oil catchers are equipped with deep purification sorption filters which consist of three units – sand separators, oil catchers, and a sorption filter 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.
  3. Sorption unit (module), which collects the dissolved oil.

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.

Activated charcoal, and various synthetic compounds may be used as sorbents.

In the application of the activated carbon, adsorption occurs, which reduces the BOD indicators. Efficiency – 60%.

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

Sand-oil catchers 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.
