Odour Control and Bio-remediation
issues are often concerned with regulatory compliance issues.
NVT is able to offer environmental solutions for industrial/environmental
problems that meet, and often exceed, new or existing EU regulations.
This field of operation is often event-oriented.
Royal Naval Dockyard.
Rosyth. Scotland.
A bio-catalytic approach solves a challenging odour problem.
Restored after massive fish influx.
A shoal of sprats estimated total weight; 15 thousand tons,
entered Rosyth Royal Naval Dockyard, a Babcock International
dry dock holding basin located on the Fife coast off the River
Forth, Scotland.
This enormous influx of sprats, an oily fish similar to sardines,
quickly used up the basin?s finite oxygen supply and then
died. First they floated on the surface then sank to cover
the bottom of the 66-acre basin.
Babcock Defense Ltd. The lead contractor to the Royal Navy,
considered the following treatment options to clean up this
challenging and unusual water pollution project. Chemical
treatment was ruled out because of the expense of treating
2.2 million M3 of basin sea water, and the potential consequences
of discharging a large amount of treated water into a scenic,
recreational and commercial water way. Mechanical solutions,
such as dredging were ruled out immediately because the disposal
of fish waste was unacceptable within UK and European Union
environmental regulations.
Instead, Babcock Defense approached NanoVapor to employ its
bio-catalytic ?Do no harm? solution. This Pro-biotic's scientific
method uses naturally occurring bacteria and enzymes to produce
bio-catalytic reactions in high-volumes, low-concentration
contaminated environments. NanoVapor developed its nitrogen-fixing
and solids reduction system based upon many years of use in
wastewater treatment plants and animal confinement waste handling
systems and working alongside their American associates NanoVapor
USA.
In this case the primary objectives were to stop the odour;
balance the nutrient substrate to support massive growth in
the introduced microbial population; inoculate the bio-solids
with live bacteria; and create a self-limiting system that
does no harm to the water environment.
Proprietary carbon balancing and biochemistry technology
accomplished the first two steps. The latter ?polished? the
water column 38 feet deep. This step also adjusted the carbon
nitrogen ratio and set the stage nutritionally for the next
step. A hydro-cannon projected a stream of semi-solids hundreds
of yards in length across the water surface.
Using a proprietary microbial formulation and nutrient system,
NanoVapor grew bacteria in a 6,000 gallon vacuum tanker. In
addition the company built a flexible heat exchange system
on site that ran off a steam generator and an air injection
system inside the tanker to create and maintain appropriate
temperature and oxygen conditions to boost a massive bacterial
population count. Babcock Defence supplied valuable logistical
support .
