Background
Barclye was a decommissioned water plant that was required on a temporary basis to be used during dry weather periods. The only treatment onsite was a drum filter and chlorination before the water went into supply. The main issues onsite were turbidity, colour and cryptosporidium
| Project Name: | Barclye Water Treatment Works |
| Client: | Scottish Water |
| Capacity: | 15-20 L/s |
| Project Scope: | Design, supply & commission |
Project Highlights
• Off-site manufacture
• Flow rates of 15-20 L/s
• Turbidity was reduced by 30.5%,
• Aluminium, iron & manganese reduced by 14.33%, 25.5% and 77.37%
• Rapid installation and commissioning
Solution
Due to the sites hydraulic profile, two automatic Spruce Filter 180’s were installed in a 12 week period operating at the head of the works giving flowrates in the region of 15-20 l/s. The two 2m diameter vessel, pipework and backwash pumps were installed in an existing room of 5.5m by 4.7m with the control panel being located in an adjacent room. As the only power supply onsite was single phase, a three phase diesel generator was put in place to power the backwash pumps for the weekly 15 minute backwash. As the water is not chemically treated, the weekly backwash water was collected in an intermediate holding tank, and slowly discharged to soak away.
Performance
With the Spruce Filter in place the turbidity of the final water is reduced by an average of 30.5%, and the total aluminium, iron and manganese is reduced by an average of 14.33%, 25.5% and 77.37%.
As a result of adding the Spruce Filter to the works it was able to go online in January 2010 to supplement the water supply to the area
“Working to a tight deadline on a difficult geographic location FilterClear® supplied a very well engineered and innovative solution that has allowed us to maintain our supply in trying weather conditions.”
