Passive anti-odour filters effectively remove odours and other toxic substances released by sewerage in the sewage network. Their effectiveness has been confirmed by specialist laboratories.

They come in two versions:

• manhole – ENPeco
• chimney – EZK, KF

ADVANTAGES

• competitive price
• easy and inexpensive installation
• very high effectiveness of removing odourous and toxic compounds
• maintenance free
• resistant to temperature changes and daily changes in the amount of sewerage
• resistance to corrosion and chemical compounds activity
• reliable – have been tested in all weather conditions

CONSTRUCTION

The components of passive anti-odour filters (manhole anti-odour filters and chimneys) are made of polyethylene, polypropylene or stainless steel and are resistant to long-lasting contact with aggressive substances that can be found in sewer installations.

The filters inside the device are filled with:

• impregnated activated carbon layer
• Ecol-Unicon catalytic carbon
• impregnated activated carbon layer and chemical agent
• biofiltering substance.

OPERATION

Passive anti-odour filters produced by Ecol-Unicon are designed to provide free passage of air through a replaceable filter. The size of the filter has direct impact on the effectiveness of air treatment and operation time of the device. The filter can be filled with biomass or an appropriately selected activated carbon. Passive anti-odour filters are equipped with a removable vent/cap that enables easy replacement of the filter. Additionally ENPeco manhole anti-odour filters are equipped with water drainage system. Additionally ENPeco filter is equipped with EUcleanON^® system, which cleans the device from any solids and sediments while draining water at the same time.

Passive anti-odour filters are effective in eliminating odours and have a wide range of applications, among which are:

• pumping stations and dry well pumping stations
• household water treatment plants
• food processing facilities
• expansion wells
• holding tanks (septic tanks)
• percolation systems
• manholes (e.g. in touristy or representative areas, old sewer systems, old town areas, housing estates etc.).

PASSIVE ANTI-ODOUR FILTER TYPES

ENPeco manhole anti-odour filter

• can be installed under manhole slabs
• easy installation in manholes of 600 to 800 mm in diameter
• replaceable filter element
• simple construction that does not need special attendance

EZK integrated supply-exhaust chimney

• can be installed in pumping stations and dry well pumping stations as well as other facilities
• comes in two diameters: 110 mm and 160 mm
• effective anti-odour alternative for two traditional ventilation chimneys
• has a mounting plate which provides correct sealing
• replaceable filter element

KF pipe chimney

• can be installed in pumping stations, dry well pumping stations, wastewater treatment plants, septic tanks as well as other facilities
• comes in two diameters: 110 mm and 160 mm
• effective anti-odour alternative for two traditional ventilation chimneys
• replaceable filter element

Operation

Taking into consideration difficult environment in which manhole anti-odour filters operate it is advisable to inspect the site and the work of the device. During such inspections the anti-odour filter must be cleaned of any remaining garbage, sand, rocks and water should be poured into the EUcleanON^® siphon/system in order to check the correct operation of the device.

Technical solutions used in the devices enable simple replacement of the filter element without the need to purchase a new chimney or housing element, thus reducing maintenance costs.

IN ORDER TO REPLACE ODOUR NEUTRALISING COMPONENT THE FILTER/NEUTRALISING COMPONENT HAS TO BE REPLACED (A BAG FILLED WITH ACTIVATED CARBON/BIOFILTER)

• chimneys and anti-odour filters are maintenance free
• a replaced biofilter component can be composted
• a replaced activated carbon component must be collected by a specialist company having necessary certificates allowing for utilising hazardous substances.

THE OPERATION TIME OF EACH DEVICE DEPENDS ON THE AMOUNT OF CHEMICAL COMPOUNDS REMOVED FROM AIR ABOVE THE SEWAGE.
