MS Series Bar Screens Replace Two-Stage Screening System

In 2004, the Department for Regional Development announced plans to upgrade the Limavady Wastewater Treatment Works, which was part of a 28 million dollar capital works program in Northern Ireland. Shaun Woodward, Regional Development Minister said, “Significant investment is required to upgrade water and wastewater infrastructure in Northern Ireland to protect public health, ensure beaches, safeguard the environment, and respond to increasing demand.”

As part of the upgrade, Northern Ireland Water (NIW), the local water authority, found it necessary to search for equipment that would hold up to the task of handling the remarkable amount of screenings brought in by the high quantity of rainwater flowing into the combined sewer system. In particular, problems often occurred at the headworks portion of the treatment plants due to the first flush of heavy rainstorms. NIW knew that only a very heavy duty screen at the front of a treatment facility could hold up to the beating and capture the rubbish flowing in from the deluge without jamming. NIW also had to abide by UK screenings capture requirements.
