Types of wastewater treatment systems in the UK
FILTER SEWAGE TREATMENT PLANTS - NON-ELECTRIC
For Houses and Small Business Premises - 1 to 5 persons
FILTERPOD non-electric sewage treatment plants are our own design.. They use non-degradable RDX filter media.
THREE STAGE SEWAGE TREATMENT PLANTS
For Houses, Housing Developments, Small and Large Businesses, Camping Sites, Hotels, Holiday Parks and Holiday Homes - 1 to 5000 persons
APEX wastewater systems are specialised plants which can work down to very low population numbers. Most plants really struggle when underloaded below 50% of what they were designed to do.
DISC SYSTEMS (rotating biological contactors or RBC's)
The original package wastewater treatment systems. RBC's are now made by only a few companies as technology has changed.
ACTIVATED SLUDGE SEWAGE TREATMENT PLANTS (ASP's)
Houses, Small Housing Developments, Small to Medium sized Businesses - 1 to 30 persons
VORTEX™ sewage treatment plants produce some of the cleanest effluent of them all and have an unbeatable ammonia reduction. They have an EN 12566-3 test effluent standard of an amazing 0.4mg/L ammoniacal nitrogen, which is over 40 times lower than the Environment Agency requirements. The VORTEX™ treatment process reduces pollutants by up to 98.9%.
SEPTIC TANK CONVERSION TREATMENT UNITS
Add on to existing Septic Tanks. For Houses, Housing Developments and Commercial Use - 1 to 5000 persons
BIOKUBE septic tank conversion treatment unit produces a very high standard of effluent, but is, like the Balmoral SBR, a sequencing batch reactor. The domestic range extends up to 30 persons and the units above 10 persons need a pumping station added to the system. Full EN 12566-6 certificate.
Please ring us for details.
AQUAPOD Adds on to an existing, or on-site constructed septic tank to provide full sewage treatment. The plants range from 50 to 5000 persons.
VORTEX Can add onto an existing septic tank to clean the sewage to a standard which complies with the General Binding Rules for discharge to ditches and watercourses. Full EN 12566 - 6 certificate.
Septic Tank or Sewage Treatment System?
If you are considering using a septic tank instead of a sewage treatment plant, make sure that the ground is suitable for a foul water soakaway drainfield, as over 70% of UK sites fail the mandatory tests that allow them to be installed or replaced. Either the Soakaway Trial Site Assessment Hole, to find out the highest level of the water table, or the Percolation Tests, to find out how porous the soil is, fail these tests.
Most modern properties also don't own enough land to enable a soakaway drainfield to be installed. You need a VERY large, treeless garden for a soakaway drainfield!
When you install a sewage treatment plant, the Soakaway Drainfield size required is reduced by 20%, which more than outweighs the additional cost of the Sewage Treatment Plant.
The installation cost of a sewage plant is also less than that of a septic tank, as the plant is smaller.
