The phenomenon referred to as water

The phenomenon referred to as waterhammer can be used to create the pressure required for reverse osmosis of
seawater, this has been described in a previous paper [ 11. A subsequent paper then investigated economic feasibility
and concluded that it could achieve significant cost savings as well as eliminating the need to bum fossil fuel energy
for seawater desalination [2]. It is necessary to investigate the theoretical feasibility of using hyclro-ram for this
purpose. A major question is whether the hydro-ram (typically used for pumping relatively small quantities of river
water to a higher level) can pump the large quantities of seawater required for desalination. Literature is reviewed in
respect of the various designs and especially large designs and the theories of its operation are explained. Formulas
for determining the output of a particular size of ram are identified. Seawater corrosion is also considered. It is
concluded that it is both economically and technically feasible for this simple piece of apparatus to be used for the
desalination of seawater.
