Andel FilterSepta®

Designed to work in conjunction with Andel’s BundGuard^® dewatering system

FilterSepta^® is an above-ground interceptor and filter system that must be used in conjunction with Andel’s BundGuard^® dewatering system.

Ideal for both retro-fit and new installations, FilterSepta^® works as an above-ground interceptor and filter system and is ideally partnered with Andel’s BundGuard^®. 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.

Benefits at a glance

• FilterSepta^® performs to, and is fully certified as, a Class 1 full retention oil/water separator and relevant section EN858-1:2002
• 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 minimising metal corrosion
• Extremely high gravity outflow of 3 litres per second (site conditions may vary)
• Sludge volume of 100 litres – allowing for extended maintenance breaks
• Automatic bypass overflow returns water to the bunded area – avoiding contamination to the unit.

How FilterSepta^® works

Water is pumped into the first chamber through a T-section which prevents the bottom of the chamber being disturbed by the water flow. Any silt and heavy solids will settle at the bottom of the chamber as the outlet to the next chamber is at a high level. 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 free oil is allowed to pass through. If over time there is a significant build-up of oil in the second chamber, there is an oil sensor that will shut off the BundGuard^®, which in turn will alert the site of an issue, allowing simple maintenance to deal with the problem.

Gravity balances out each chamber from the pumped water entering the first chamber, which progressively reduces the flow from one chamber to the next chamber, giving more time for any suspended solids to fall to the bottom of the chambers.

The final stage before discharge 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.

FilterSepta^®

A cost-effective, above-ground interceptor that performs to, and is fully certified as, a Class 1 full retention oil/water separator and relevant section EN858-1:2002. FliterSepta^® is designed for easy installation and maintenance, HDPE construction means FilterSepta^® is lightweight and robust.

Easy to install and maintain

FilterSepta^® is constructed from UV-resistant, impact-resistant High Density Polyethylene (HDPE). It is lightweight when empty and easy to install by a two-person team with no mechanical lifting equipment required. Manual lifting lugs are positioned to allow for safe lifting below head height, crucial for high voltage sites

Maintenance can all be easily managed onsite with access to the FliterSepta^® unit via the open lid. Both coalescing filters are easy and safe to remove, clean and return to use with need for disposal or replacement. The silt trap chamber needs emptying from time to time this is also easy and safe to empty, clean and return to use.

If there is a significant build up of oil within the second chamber, an oil sensor alarm will shut off the BundGuard^® system, which in turn will alert the site to remove any excess oil from the chamber.
