In late 2007 following a detailed technical evaluation Christ Kennicott were chosen by Alstom Power to design and build a complete boiler feedwater makeup plant to serve the new Grain Power Station in Kent. For the first time in the UK seawater was to be used as a raw water. This high salinity feedwater also contained high levels of suspended solids and would require substantial purification before it could be used as boiler feed water. The following technologies were integrated into a fully automatic plant designed to produce upto 50m3/hr of 0.2µS/cm boiler make-up water.
- Coagulation
- Lamella Clarification
- Pressurised Ultrafiltration
- Seawater Reverse Osmosis c/w Energy recovery pressure exchangers
- 2nd stage Brackish water Reverse Osmosis
- Mixed Bed ion exchange polishing.
Raw water TDS : 20,000 mg/l
