Refurbishment of chemical dosing facilities at 3 sites

As part of a refurbishment project with GBM, Verder were invited to tender for the supply, installation and commissioning of chemical dosingfacilities for 3 sites. The 3 sites varied in their requirements, some specifiying only chemical storage and control facilities, others requiring a combination of poly make-up, phosphate control and pH correction.

Ashford Common STW

 

Verder supplied chemical storage facilities including a tanks, carbon-steel rubber lined fill pipes , concrete bund, full GRP gantry system and control panel. The kiosk with the control panel also contains the fill point, sample run-off container and full level indication panel. The kiosk also houses a wash hose and spillage kit for any accidents or wash-down procedures. The system was designed, built and installed by Verder, hydrostatically tested and commissioned.

Shalford STW

The Shalford STW serves the local Guildford area. The dosing facility required a complete overhaul, however the dosing process had to continue during the fitting.

Verder provided an external temporary dosing system, allowing the site to stay 100% operational during the renovation. A total of 6 dosing cabinet systems were fitted including polyelectrolyte, sodium hydroxide, ferric and a poly make-up tank. The plant-room itself was also renovated with the old equipment being removed and the building painted.

Crawley STW

Verder provided chemical dosing for phosphate removal and pH buffering with supply of a packaged plant system featuring the dosing cabinets, pipework, control panels, valves and kiosk. In addition, Verder provided a spares and maintenance plan.
