PROCESS DESIGN CAPABILITIES
Phoenix has extensive experience ranging from the design, construction, commissioning
and operation of many on-site leachate treatment plants, in the UK and overseas, to
providing what we consider to be an optimum solution for our Clients. Our designs are
based on unrivalled experience in the design, construction and operation of many types of
leachate treatment systems.
Our specialised experience in the design of a range of aerobic biological treatment
processes for treatment of landfill leachates, includes a number of recent plant. These treat
larger volumes of leachate each day, and achieve reliable and complete removal of NitrateN using an innovative and award winning process design.
Since our Process Director, Howard Robinson, first developed the modified Sequencing
Batch Reactor (SBR) process for leachate treatment during the late 1970s, and applied it on
a full scale at the Bryn Posteg Landfill in 1982, this process has become the most widelyadopted and successful leachate treatment system in the UK.
Although in many recent designs, our robust extended aeration biological treatment process
has been adapted to incorporate membrane separation of solids, particularly where
additional COD removal has been required, or where very low levels of solids are critical in
treated leachate discharges, we continue to design and build many simple, low-maintenance
plants based on our tried and tested modified SBR process.
Our leachate treatment plant designs are always based on sound state-of-the-art technical
knowledge, and where that knowledge has been lacking, then we have undertaken
innovative research and pilot-scale treatment trials to obtain it. This has allowed us to
continually refine the operation of SBR plants for treatment of leachates, and advances
include an extensive array of fail-safe process controls, remote interrogation and recording
of plant operations, and alarm systems. All of these facilities act to minimise the required
inputs from a plant operator. Our staff have received national and international awards for
this knowledge-based innovation over several decades.
