Clay has been foamed and extruded using novel technology, to produce a lightweight media
called StarLight C. Altering the production process parameters allows control of the media
diameter, density, strength, and surface ...

Biological aerated filters operate as fixed film systems in which micro-organisms grow on a
submerged fixed structured or granular inert support media within an aerated reactor (Stephenson
et al., 1993). Periodic backwashing ...
Bedard, P.(of Water Sciences, Cranfield University, 1999-03-03)
High rate biofiltration is a process which has gained popularity in recent years as effluent discharge
consents become ever more stringent and the available land to construct new facilities becomes
more scarce.
This ...

This paper describes the background of recent engineering changes to the BiobeadTM system. In
particular known design pitfalls are described. The development of technically improved aeration
and flow distribution methods ...

The Biological Aerated Filter is an accepted wastewater treatment option that has the advantage of
treatment and solids separation in a single, compact reactor. Choosing the correct support media for
the attached biomass ...
Holmes, J.; Dutt, S.(School of Water Sciences, Cranfield University, 1999-03-03)
The complexity of the Huddersfield works and the issues addressed by the scheme design
engineers are highlighted, including the need for a robust nitrification process due to the high
levels of nitrification inhibition ...
Rundle, Howard; Chen, Jeffrey J.; McCarty, Don(School of Water Sciences, Cranfield University, 1999-03-03)
Biological aerated filters (BAF's) are compact wastewater treatment reactors capable of achieving
biological oxidation and solids removal in a single reactor. The basic principle of operation is that
biomass grows on the ...
Martin, J.(School of Water Sciences, Cranfield University, 1999-03-03)
The use of the activated sludge process is a very well known technology. It is and has been used
very widely in full scale plants from its first development at the Davyhulme works in
Manchester. However this process ...

This paper reports on the performance of the BiobeadTM version of the Biological
Aerated Flooded Filter Process over the last few years. More than twenty of these
units have been installed in the U.K. and the operating ...
Clarke, S.(School of Water Sciences, Cranfield University, 1996-06-12)
Biological processes have been used to treat waste waters for many years in order to
improve public health, remove offensive odours and to reduce pollution in the receiving watercourse.
In the 1980's public concern led ...
Pearce, Peter A.(of Water Sciences, Cranfield University, 1996-06-12)
Aeration costs account for a large proportion of the total running costs of
biological aerated filters (BAFs) which are in themselves an energy intensive
form of treatment process. Optimisation of oxygenation efficiency ...

Halcrow Scotland were appointed by Grampian Regional Council (now North of
Scotland Water Authority) in April 1993 to carry out the Aberdeen Wastewater
Treatment Feasibility Study. The study started with a verification ...
Stephenson, Tom(School of Water Sciences, Cranfield University, 1996-06-12)
True biological aerated filters (BAFs) combine two unit operations in one reactor:
aerobic biological treatment and subsequent biomass separation from the effluent
(Stephenson et al., 1993). The submerged media used as ...

1. The town of Poole in south east Dorset has undergone substantial development
during the 1980's. Wessex Water recognised the pressure on the water services in this
region and commissioned a strategy study for this ...
Sagberg, Paul; Grundness Berg, Kirsti(of Water Sciences, Cranfield University, 1996-06-12)
Both the local situation in the inner Oslofiord and the political decisions of the countries
surrounding the North Sea called for further treatment. Through 1989 and 1990, VEAS
put bits and pieces of known technology ...
Rundle, Howard(School of Water Sciences, Cranfield University, 1996-06-12)
Two plants are described which are designed for partial (or roughing) treatment of
settled sewage, and settled sewage with dairy waste, and some of the lessons learned
from these are described. These plants are ColOX ...
Mann, Allan T.; Stephenson, Tom(School of Water Sciences, Cranfield University, 1996-06-12)
1. Biological aerated filters (BAFs) are submerged three-phase fixed media
reactors for wastewater treatment. A major characteristic of BAF reactors is the use of
granular media which allows solids separation as well as ...
