Above-ground Class 1 full retention oil/ water separator.

Application

Suitable for both new installations and retrofit.


Designed for instances when existing oil/ water separating pump systems may need additional support to prevent hydrocarbons escaping and contaminating the environment, providing a secondary safeguard for sites where extra caution is required.


Recommended for environmentally critical sites and/ or where there is concern about pumped water discharge through soak-away or surface water drainage, where there is no underground drainage interceptor or separator.

Description

Cost-effective, above-ground interceptor that performs to the requirements of a Class 1 full retention oil/ water separator and relevant section EN 858-1:2002. FilterSepta® eliminates the need for costly underground interceptor tanks to be installed.


Must be used in conjunction with Andel’s BundGuard® dewatering system. In rigorous tests, BundGuard® is shown to perform to less than five parts per million of oil present in pumped discharge water. FilterSepta® removes any emulsified oil or debris, however small, still present in the pumped water, allowing for safe discharge through existing surface water drainage.


Features and benefits:

  • Performs to the requirements of a Class 1 full retention oil/ water separator and relevant section EN 858-1:2002.
  • Accessible silt trap chamber – easy and safe to empty, clean and maintain.
  • Accessible coalescing filter media – both filters are easy and safe to remove, clean and maintain on site, no need for disposal or replacement.
  • If there is a significant build up of oil within the second chamber, an oil sensor will shut off the BundGuard® system, which in turn will alert the site of an issue.
  • Lightweight, robust and UV-resistant.
  • No mechanical lifting equipment required for delivery and installation, and well within capacity of a two-person lift.
  • Robust double-extrusion welded throughout for extreme durability.
  • Manual lifting lugs positioned to allow for safe lifting below head height – crucial for high voltage sites.
  • No exposed metal parts – eliminating the risk of arcing in high voltage sites and minimizing metal corrosion.
  • Extremely high gravity outflow of 3 L/s (site conditions may vary).
  • Sludge volume of 100 L – allowing for extended maintenance breaks.
  • Automatic bypass overflow returns water to the bunded area – avoiding contamination to the unit.


How FilterSepta® operates:

Water is pumped from a BundGuard® into the first chamber through a T-section, preventing the bottom of the chamber being disturbed by the water flow. Silt and heavy solids will settle at the bottom of the chamber and as the outlet to the next chamber is at a high level, remain in the first chamber. Free oil will also separate and form a layer at the top and is allowed to flow in to the next chamber.


The outlet to the third chamber is at a lower level, so only water that is free of oil is allowed to pass through.


If over time there is a significant build-up of oil in the second chamber, an oil sensor will shut off the BundGuard®, which in turn will alert the site, allowing for simple maintenance to be carried out to remove the oil.


As pumped water enters the first chamber, gravity balances the water level in each chamber, progressively reducing the flow from one chamber to the next, giving time for any suspended solids to fall to the bottom of the chambers.


The final stage before discharge to drainage is for the water to flow through two Coalescing Filters that serve to remove any remaining suspended solids and emulsified oils as in a Class 1 interceptor.
