A leading independent monthly publication, the “International Water Power and Dam Construction” set up in 1949 to serve the needs of those involved in dam construction and the hydroelectricity industries, recently published an in-depth article about the ground-breaking GoFlo self-cleaning screen. The article is called Go with the flow and was written by, Philip Davis, Managing Director of GoFlo Screens Ltd and one of the UK’s leading hydro power installer companies, Renewables First,
The article outlines the origin and driving factors behind the innovative design features of the GoFlo self-cleaning screen. It has long been said that “necessity is the mother of invention” and as the article sets out, this certainly holds true for GoFlo. The article explains how the GoFlo screen design was inspired and designed by engineers at Renewables First, a leading player in the UK hydro sector, and how their experience in abstracting water for hydro power schemes has taught them that bolt-on, retrofitted screen cleaning systems are far from ideal.
The article explains how the necessity for hydro schemes to meet ever-more stringent fish and eel screening regulations, combined with an obvious gap in the market for a product that can easily meet this need, as well as providing other useful design features, led to some remarkable design innovation.
As Phil Davis explains, ”The design team for GoFlo started by considering what a hydro power site needs, rather than the conventional thinking of ‘how do we retrofit this cleaning system on that screen?’”. By looking at the problem this way round, the following key design requirements were identified:
■ Compliance with fish and eel regulations.
■ Long-term reliability.
■ Permanently clean operation.
■ Low maintenance costs and simple maintenance.
■ Visually unobtrusive.
■ Remote monitoring and control.
The article explains in detail how the GoFlo self-cleaning screen design satisfies all of these requirements and more. It also explains how the design is also suitable for most other (non-hydro) water abstraction sites, both in the UK and overseas.
