    SewageTreatment Plant

    Hamworthy is the world’s leading manufacturer of marine sewage treatment plants.For over three decades Super Trident sewage treatment plants have been widely regarded as standard specification on all vessels up to the largest cruise liners.

    Membrane BioReactor System

    Hamworthy Membrane BioReactor (MBR) produces the highest quality discharge without requiring any addition or generation of chemicals that are hazardous to the environment or ship operation.

    Hamworthy Ballast Water Systems

    Hamworthy’s range of AQUARIUS™ ballast water management systems offer owners and operators a choice of ballast water treatment solutions with greater flexibility.

    Vacuum Toilets

    The Hamworthy vacuum flush toilet has been designed to be mechanically simple, operationally reliable and stylish in appearance. It uses air to drive waste through the toilet and vacuum piping to the treatment tank or intermediate collection tank. This contemporarily styled toilet has a built-in vacuum breaker and flush memory. The control mechanism can be accessed without removing the bowl. By using only approximately 1 litre of water, a dramatic reduction in the amount of wastewater is realized.
