Bio decontamination Ltd (BDL) provides cutting edge hydrogen peroxide dry vapour fumigation solutions to the healthcare sector, pharmaceutical Industry, research laboratories, care homes, hotels and cruise ships
Leading the way in Bio decontamination
Controlled, Effective & Fast
Bio Decontamination Ltd (BDL) are specialist in providing a unique, rapid and flexible 24/7 decontamination service to all manner of clients. The solution can be delivered standard or bespoke, mobile or fixed. We work closely with our clients in providing a first class decontamination process to suit there needs and meet their expectations.
The term “dry vapour” is used to describe a vapour made up with droplets of a consistent size below 1µm; historically droplet size consistency was difficult to achieve but technology has now provided equipment that will deliver just that. Using nozzles manufactured to precise tolerances and employed as part of a balanced atomising process, liquids are dispensed meeting the droplet size criteria. When generated the droplets which make up the mist have certain characteristics; they do not disintegrate but keep their shape until evaporation takes place and the vapour is formed.
BDL has developed a system that will dispense liquids into small volumes such as cabinets, and into large areas were the only restriction on size is the amount of compressed air available. Another factor is that, no matter how large the area, the cycle time from start of gassing to end of “kill time” is constant. The patent dry vapour system enables the preferred liquid to be dispersed through a single or multiple nozzles (calculated on volume to be treated) in a fine plume of droplets that have a consistent size depending on the application but are <1µm. These then act according to the Brownian motion (the erratic and constant movement of tiny particles when they are suspended in a fluid or gas).
The process “Real time monitoring” providing Quality Assurance of VHP process.
The process is controlled in real time, our standard practise is to place a number of monitored remote (Temperature/Relative Humidity) sensors in tandem with our bio-indicators around the target facility at different levels and in areas thought to be the most difficult for the vapour to access.
Each sensor is individually identifiable and sends regular readings to the data collection unit which then relays the reading to a laptop computer pre-loaded with software to produce a “real time” line graph of the readings from each sensor. Successful dispersion is indicated by a rise in the starting relative humidity reading of at least an additional 15%, see graph. Readings of over 100% would suggest that the sensor was close to the nozzle. Our specialised team of staff are able to instantly identify any area in the room that is not being subjected to the disinfectant vapour by a failure of the sensor to record the expected rise in humidity.
Control of sterilant discharge is from outside the area and each nozzle is independently managed. This means the humidity in the area can be balanced as the sterilant is introduced, which avoids optimum humidity being compromised in parts of the area and prevents wetting taking place. Monitoring the humidity and controlling the process with sensor information leads to an effective and dry process.
The process is validated through the use of biological indicators, these are in the room and exposed to the disinfection, after which they are cultured in a suitable media and under appropriate recovery conditions as specified by the manufacturer. If no growth occurs, the disinfection process is deemed to have worked.
Our Hydrogen peroxide patented system:
Is an effective bactericide, fungicide, virucide and sporicide, providing a six log kill against such pathogens as MRSA, c diff etc.
Is delivered as a dry vapour allowing furniture including sensitive medical equipment to be also subjected to the decontamination process.
Is fast, facilities can be up and running within two hours of the decontamination process.
Raises the humidity in the room to ensure the dry vapour is evenly and thoroughly distributed throughout the facility.
Collects humidity reading during the decontamination process to confirm that all parameters of the process are met.
Cost effective, and competitively priced.
