ProVent
Anti-Foaming
Description
The
treatment of water is a very large and diverse industry.
It encompasses sewage plants from local authorities treating
vast quantities of both domestic and industrial sewage
to individual companies treating their own industrial
waste with in-house effluent plants.
Modern
industrial effluent and wastewater treatment procedures
produce foam, which not only limit the capacity of the
plant, but also can be a hazard to both man and the environment.
Environmental
controls mean that not only do effluent streams have to
be controlled, but also that the recovery of valuable
products has to be possible. ProVent not only increases
the effectiveness of systems but also aids recovery of
valuables. By eliminating foam, ProVent also improves
the visual aspects of treatment plants.
Main
Uses
ProVent
is a highly effective silicone based antifoam emulsion,
which we have developed specifically for Northumbrian
Water and other applications where quick knockdown of
foam is required. ProVent is used at low concentrations.
It is versatile in processing operations and acts physically,
not chemically, avoiding product contamination. ProVent
is particularly useful where chlorination of sewage treatment
occurs before final discharge.
Main Advantages
Inert
non-toxic
COD value less than 300mg/g
BOD value of approximately 130mg/g
Negligible effect on bacteria in a waste digestion system
Inorganic so will not increase oxygen demand
Acceptable under UK, Europe & US food regulations
Application
ProVent
disperses easily in both hot and cold aqueous systems,
requiring only mild agitation to disperse it completely
in the foaming system.
The
quantity of ProVent required in general between 100 and
500ppm. (500ppm = 0.5 litres of product to 1000 litres
of foaming media).
