<p>A pumping apparatus 10 for a water treatment plant comprises a gas supply 15 and at least one gas turbine 11 connected to the gas supply, the gas turbine(s) being connected to drive at least one primary pump 12. A waste heat boiler 26, with a feed water input, has an exhaust gas input 26a which receives exhaust gas from the gas turbine(s) and generates steam from the feed water. The waste heat boiler also has a steam output 25 which is connected to at least one steam turbine 20. The steam turbine(s) is/are connected to drive at least one secondary pump 21 and further have an exhaust steam output 28A. The apparatus further comprises a distillation apparatus 28 which receives the exhaust steam and untreated water 30, wherein the distillation apparatus operates to provide feed water 29 to the waste heat boiler. A method of discharging exhaust gas 35 containing carbon dioxide is also claimed which comprises the steps of receiving a wastewater stream 37 from a water treatment apparatus and combining the wastewater stream with the exhaust gas such that at least a proportion of the carbon dioxide is dissolved in the wastewater stream.</p> |
