siloxane removal system maintenance and media change

Project - Siloxane Removal System Maintenance and Media Change

Client - Dwr Cymru Welsh Water 

Location - Cardiff Advanced Digestion WwTW
                  - Five Fords WwTW
                  - Afan Advanced Digestion WwTW

Sub Contractor - PpTek

Date - June/July/August 2017

 

Dwr Cymru commissioned Marches Biogas Ltd to manage the maintenance works and media change of the Parker PpTEK Siloxane Removal System’s (SRS) at Afan WwTW and Five Fords WwTW.

Acting as the principal contractor, Marches Biogas sub contracted Parker PpTek to carry out the filter media change.  In order to allow Parker PpTek to safely work on the SRS Marches Biogas firstly had to isolate the system from the biogas holder, CHP and other associated biogas equipment before purging the SRS and associated pipework with oxygen free nitrogen.  Once Parker PpTek had completed the media change and carried out any system component checks Marches Biogas repurged the pipework and SRS to allow the safe recommissioning of the unit.  

Throughout the time onsite, Marches Biogas staff were responsible for the Health & Safety of all parties and ensured that all procedures documented in the risk assessments and method statements, submitted to Dwr Cymru prior to the works, were followed.

Pipe Identification Marking

It is essential to know what is running through your pipework, whether it is biogas, digestate, process liquids or hot water, especially when you need to isolate pipework in a hurry.

Principle Biogas can supply and mark small sections of pipework, or complete facilities.
