Tintometer
of a laboratory measurement, but in
a portable instrument. Highest accuracy
is guaranteed in the lowest
turbidity range from 0.01 NTU, while
maintaining the precision level in the
highest turbidity range up to 4,000
NTU. The TB350 is available as an
infrared or white light version, is compliant
with valid ISO 7027 and U.S.
EPA (pending) regulations and standards.

Recovering phosphorous from
sewage sludge - on site
The most promising phosphorusrecycling
methods, in terms of
sustainability, conservation of resources,
effectivity and long-term
cost-efficiency, are those processes
in which phosphorus is recovered
from sewage sludge directly on
site. One such process has been
developed by this company in cooperation
with the CUTEC research
center at the Clausthal University of
Technology. It can be adapted to
different recycling capacities and
will be ready for commercial use in
2023. The recycling system can be
added to a wastewater treatment
plant, eliminating the need for transportation
of the sewage sludge.
The sludge is dried on-site and the
phosphorus recovered - without
incineration and ash storage and
without using chemicals. The sewage
sludge is fully utilized, generating
marketable products. Recycled
phosphoric acid, for instance, has
a wide range of applications in a
variety of industries. The process
requires very little space and can
be scaled to suit different recycling
capacities, making it suitable for
municipalities of all sizes. Hall B2,

Using ozone to
combat micropollutants
Ozone breaks down trace substances
through oxidation or converts
them into smaller molecules,
which are easier for micro-organisms
to break down in a post-treatment
stage or can be removed by means
of absorption. This combination
of processes delivers an improved
overall cleaning result and generally
removes more than 80% of trace
elements from wastewater. At the
same time, operating costs are lower
than those of comparable technologies.
This company's new O3 system,
Dulczon OZLa, can be fitted
with up to 16 O3-generator modules.
The modules can be activated and
deactivated as required. The amount
of O3 produced can therefore be
adapted to fluctuations, for example
in a clarification plant where varying
volumes of waste water are treated.
