Technical Spill Control Products
IFF produces a variety of essences for the perfume and toiletries industry and therefore has a need to store several different chemicals, fuels and packaging materials on site. As part of the company’s efforts to reduce the risk of a pollution incident and comply with legislation, it was decided that a firewater retention pond would be installed, into which any firewater runoff generated in the event of an emergency on site would be diverted. Firewater runoff contaminated with either the chemicals stored on site or foam used in dealing with chemical fires can be a major source of pollution once it enters a drainage system. The major stumbling block to the project was a cost effective and reliable method of sealing the discharge drain and diverting the out flowing firewater into the new retention tank.
The ATG Group Solution:
A 100,000 gallon tank was constructed in the grounds of the plant close to both the front boundary and the main storm water drain discharging from the site. The decision was taken to install an Envirovalve Emergency Drain Security System as the final seal to the drain in the event of a fire. The Envirovalve would be automatically activated by a signal from the onsite fire alarm system, instantly sealing the discharge from site and diverting the firewater runoff to the retention tank. The Envirovalve system is powered by a 12 volt battery which is constantly trickle fed from an associated solar panel in order to keep the unit constantly charged and in a guaranteed state of readiness. Should all the power to the site fail, the system is still able to provide the same level of security as it does not require connection to site services. The Envirovalve bladder assembly was housed in a simple block built chamber within the drainage system and a stainless steel bracket system manufactured and installed to enable mounting of the control unit cabinet and the solar panel.
The company now has complete peace of mind that should the worst happen, the resulting heavily contaminated firewater runoff is safely contained within the boundaries of the plant and cannot cause an offsite environmental issue. As the system also has full manual activation, the Envirovalve also provides instant containment should any other type of spill incident occur. Thus saving the site valuable time and money in both cleanup costs and possible fines.
Bund Water Control Unit – EMO Oil
EMO Oil Ltd are a large fuel distribution company based in Ireland who cover the whole of the Island of Ireland with their distribution services. EMO’s Technical Director was faced with the task of operating multiple sites from his desk in Portlaiose in central Ireland. A common challenge that EMO Oil encountered was the removal of the rainwater from the bund areas surrounding the tank farms. Due to the high level of rainfall in Ireland, bund areas, which are obviously sealed to provide secondary containment for the stored product, would collect large volumes of rainwater and thus reduce the bunds ability to contain the stored product in the event of a spill.
Removal of this rainwater proved to be costly especially as some sites are very remote requiring long distance travel for pump out companies. Also the cost of disposal was very expensive as it has to be classified as hazardous waste due to the contamination with fuel oils even though the majority of the liquid is simply rainwater.
The ATG Group Solution:
EMO’s Technical Director commissioned ATG to supply and install six of our Bund Water Control Units at six of the most affected sites throughout Ireland.
The bund water control units had to be intrinsically safe (ATEX approved) for use in hazardous zones and fully integrated into EMO’s existing operating system. Six units were installed at various sites throughout Ireland and now have the capability to constantly monitor the rainwater collected within the bund and automatically pump it to the on-site interceptor as the levels rise. The system also has inbuilt oil detection technology that will shut down the pumping operation and send an alarm signal to an authorised person should there be a tank failure or spill of stored product.
EMO Oil now have peace of mind that these remote depots are even safer as a result of installing this equipment. No longer will EMO be faced with the prospect of pumping out and disposing of thousands of litres of rainwater at hazardous waste rates, not to mention the time and effort that was required to visit the site and monitor the bund levels under the old system. EMO Oil will now be alerted when there is an unusually high amount of oil present within the bund areas.
Legal compliance in terms of secondary containment volume can now be maintained as the bund areas are no longer allowed to fill with contaminated rainwater. The bunds will also be constantly providing the required secondary containment capability that was intended when it was originally constructed which again brings peace of mind for EMO Oil.
