The Harrington HydroKlenze system has been stringently tested at the PIA – Testing Institute for Waste Water Technology in Germany and monitored over a period of 6 months. The results surpassed expectations and the HydroKlenze system successfully achieved accordance with the European Standard EN 12566 part 3 (Small Wastewater Treatment System), obtaining CE Mark status permitting its installation in any EU State.

|Description||Small wastewater treatment system with Biological Aerated Filter (BAF) system|
|Dimensions||1920mm diameter x 1870mm high|
|Weight||Base tank - 3 tonnes, Lid and Manhole cover - 1 tonne|
|Capacity||4170 litres (Suitable for a household of up to 8 persons)|
|Hole required||3 metres long x 3 metres wide x 2.5m deep with level base|
|Air Blower Unit||Nitto Kohki LA-60ECO (Upgraded from previous LA-80B)|
|Energy Consumption||35 watts (Previously 86 watts with LA-80B)|
|EN 12566 Part 3 Test Results:-|
|Nominal organic daily load||0.28kg/day||
The wastewater treatment system should be designed for a minimum hydraulic daily load of 150 l/person/day based on the number and size of bedrooms and a minimum organic daily load of 60g BOD/person/day to ensure adequate treatment is provided.
|Nominal hydraulic daily load||0.9m3/day|
The plant shall resist loads and stresses resulting from handling, installation and use, including desludging and maintenance, for their design life.
|Crushing resistance (calculation method)||Pass|
|Treatment efficiency (nominal sequences):-|
|COD (Chemical Oxygen Demand)||Efficiency 90.3%||Effluent 63mg/litre||
*At a test influent of greater than 300mg/litre BOD5
Notes:- Influent is wastewater flowing into the treatment plant. Effluent is the treated water flowing out of the treatment plant into the percolation area.
|BOD5 (Biological Oxygen Demand)||Efficiency 95.2%||Effluent 14mg/litre|
|SS (Suspended Solids)||Efficiency 93.3%||Effluent 21mg/litre|
|NH4-N* (Ammonium)||Efficiency 83.9%||Effluent 5.4mg/litre|
1.8kWh/day (Tested with previous LA-80B so this has now been greatly reduced)
The energy efficiency of the plant should be considered when deciding the suitability of the wastewater treatment system.
