概要

最先端の新しい拡張機能により、ウェールズのCwellyn水処理プラントに供給する水の流量を制御するため、ロトルクのインテリジェント電動アクチュエータを設置しました。


概要

Dŵr Cymru Welsh Water社は、ウェールズとヘレフォードシャーの大部分にサービスを提供する非営利の水道会社です。


チャレンジ

The new treatment and filtration system was designed to clarify the water before it enters the existing works to deal with changing raw water conditions and consistently meet all water quality standards. Appropriate flow control was required.


ソリューション

Rotork IQT direct drive quarter-turn intelligent electric actuators were installed to operate butterfly valves controlling the flow of water throughout the plant.

Clarified water (after an initial flocculation process) from the Llyn Cwellyn reservoir is filtered through first stage RGF before being pumped to the existing treatment works through ultraviolet disinfection.

IQT actuators now control all valve operations including the inlet works flow control, automatic de-sludging of the dissolved air flotation (DAF) cells, automatic backwashing of the RGF plant and the plant treating the effluent created by the clarification and filtration processes.


詳細情報

The successful completion of the upgrade project at Cwellyn ensured drinking water quality for 70,000 Dŵr Cymru Welsh Water customers in the Caernarfon area. IQT actuators were chosen because of their reliability, low cost of ownership and operator familiarity.
