The Raw Water Filtration module houses the Raw Water vessel, two independent sand filters and Filtered Water vessel. The degassed liquid is then pumped forward through the Anion Bed. The Cation Bed and Anion Bed require a regenerating every 5hours to maintain the optimum condition of the resins. Water from the Filtered water vessel is pumped forward through the Cation vessel; this then enters the degasser vessel after experiencing a carbonate removal process. Within the Acid Dosing vessel is a 5% dilution of Hydrochloric Acid, which is used to regenerate the Cation Bed. Mains water is transferred into the raw water vessel, which is then pump forward through either one of the sand filters into the filtered water vessel. On the Dosing module there is a an acid dosing vessel, caustic dosing vessel, Cation Bed, Anion Bed and Degasser vessel. In the Caustic Dosing vessel is a 4% dilution of Sodium Hydroxide; this is used to regenerate the Anion Bed.

The Gear Efficiency Apparatus has a gearbox which incorporates both spur and worm gears for which the setups can be easily switched between. The input and output power of the Gear Efficiency Apparatus is calculated for determining the Gear Efficiency of two different gear configurations. Sensors for speed and force are located on the motor module (input) and the brake module (output). The motor speed input can be controlled as well as a breaking force or load applied to the output shaft via a braking module.
By comparing the actual input and output readings to that of the calculated output values we can affectively work out the losses in the system and the efficiency of the respective gear configurations. By taking the input and output force (N) readings we can then calculate the torque (Nm) in the shafts as well as go on to calculate the power (Nm/s).
