Dear Scottish Water,
BlueTech Research is conducting a study to help benchmark and track new innovations in water technology.
As part of this we are gathering information on a number of new and innovative processes and technologies. The information will assist us in better understanding market rate of adoption of new technologies and the performance and economic benefits provided by these innovations.
We plan to monitor performance improvement over time and this will assist us with this.
In relation to this, we are submitting an FOIA request to gather information on your recent project and installation of "Invercannie Water Treatment Works".
The information we are requesting is as follows:
-Duration of contract (years)
-Specifications of the influent and effluent of the ceramic membranes (PWNT)
-Scope of supply
-Design capacity for the system in terms of kg of BOD removed, or kg ammonia and
-The technology supplier who was awarded the contract for sludge dewatering system
-Any additional operational data you may have
Thank you for your time and assistance.
Your assistance in this is greatly appreciated.
Thank you for your request for information which we processed under the
Freedom of Information (Scotland) Act 2002.
Please find the following information to your request. Invercannie Water
Treatment Works is a Ion exchange and microfiltration pilot plant.
Capacity - 6 to 8 m3/hr. Source water - River Dee. Final WQ quality –
within UK regulatory standards. Pilot plant provided by PWN Technologies.
Project Cost - £770k.
We signed a non-disclosure agreement with PWNT. So, Scottish Water cannot
release any technical, performance or commercial information about the
project. Information which is commercially sensitive is often described as
being “commercially confidential.” However, there is no single exemption
in FOISA covering “commercial confidentiality”. FOISA draws a distinction
between information where disclosure would have a detrimental effect on
commercial interests, and information which is “confidential” under Scots
law. Having specifically considered whether disclosure would be in the
public interest we consider the balance falls in favour of withholding
this information at this time and consider the information is exempt under
section 33 (1)(b) of FOISA.(prejudice to the commercial interests of any
person). “Person” includes a public authority, company and partnership.
Although Scottish Water cannot assist with the above point of your request
you may wish to contact PWNT directly who may or may not provide this
If you have any queries regarding your FOI request please feel free to
contact me and I will be happy to assist. You can do this by contacting
the following email address [email address]
You can seek a review of this response within forty working days and
thereafter appeal to the Scottish Information Commissioner.
