Wastewater Management Systems

As environmental regulations continue to evolve, ensuring that effluent is clean and safe is a growing priority. With over 35 years of experience in marine sanitation, Hamworthy plc offers innovative solutions that meet all existing and anticipated standards.

Grey & Black Water Treatment (MBR)

Hamworthy plc leads the market in waste water treatment systems for ships. The increased size and number of cruise ships have led to concerns on the impact of their waste discharges on the natural environment. Hamworthy plc has met the challenge of protecting the environment by developing a new waste water treatment process based on biological degradation and membrane separation.

This process produces the highest quality discharge without requiring any addition or generation of chemicals that are hazardous to the environment or ship operation. Recent tests conducted by an independant laboratoy (NSF) produced results exceeding the most stringent future legislative pollutant values envisaged. With over 30 years experience in waste water treatment, Hamworthy plc is ready to serve the needs of the cruise industry and the environment.

Oily Water Separator

The Hamworthy oily water separator is an advanced plate type separator which separates oil and water using the natural density differential to achieve IMO standards of performance.

This leading-edge design is also more compact, more efficient and more reliable than standard filtration equipment and is built and supplied as a complete package.

The plate pack configuration allows solids drawn in with the liquids to gravitate down through the pack to collect in the bottom. This prevents possible blockages caused by the build up of solid material.

Sewage Treatment

Hamworthy plc 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. Over 6000 plants have been installed in ships across the world.

Toilets, Vacuum

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.

By using only approximately 1 litre of water, a dramatic reduction in the amount of wastewater is realised. This contemporarily styled toilet has a built-in vacuum breaker and flush memory. The control mechanism can be accessed without removing the bowl.
