Haigh Environmental supplies high-quality, British-made inlet screens and screenings handling equipment, used in wastewater treatment plants to filter out solid wastes.

Alongside our core ACE Screener and ACE Bandscreen products, we also offer a comprehensive range of ancillary equipment, from grit removal to steel gantries, support structures and control systems. 

Haigh Screens are 6mm 2D as standard in line with WIMES, with the option of 5mm or 3mm where process requirements might need additional solids removals, for example prior to membrane treatment systems.

The Haigh ACE Screener range can process flowrates upto 80 l/sec on a Duty only Basis, with the ACE Bandscreen dealing process flow rates upto 200 l/sec on a Duty only Basis. This corresponds to sites serving populations up to 15,000. Haigh screens can be configured in a modular fashion to address sites with higher flows. 

All Haigh screens have the option of an integrated bypass, storm flow management and coarse screening options

Both screens require zero wash water, as water is taken directly into the unit from the channel for washing purposes. We provide the cleanest screenings in the industry, while saving energy and overall treatment capacity, especially in small works.

The ACE Screen range would typically require a power requirement of 25 -32 AMP 3 Phase and Neutral supply, but has a very low real-time installed power consumption due to the operating control sequence that minimises the running time of each system. The drives on the sreening systems are typically operating for a small percentage of the day, dependent on flows and loads

All Haigh Screens are all built at the Haigh Group Ltd headquarters in Ross-on-Wye, UK.

The Haigh Screening systems are well-positioned to help water companies and contractors deliver on AMP8 targets around sustainability, standardisation and more:

• Environmentally friendly – deploying a Haigh Screening System means that more  rags, plastics, wet wipes etc are removed from the wastewater streams, while using Zero Wash Water, as well as reducing landfill demands and carbon emissions. 

• Standardisation – HEC have creating standardised ranges of products to suit a broad range of site specifics for flows, loads and site constraints. This approach increases efficiencies, replicability and reduces costs and waste.

• Innovation – The Haigh Screen range is constantly under review and looking for improvements and requirements to bring to the industry.  Our philosophy is to deliver our products, support them, listen and learn from our customers, then improve and innovate.

• Cost-effective – with standard templated designs for across our product range for channel mounted or flat concrete or structural plinth prefabricated inlets, we can configure our offering to meet site and client requirements.

These can vary depending on the exact project specification and complexity,  however in general, the Screener range has a 3-4 month lead time.

Basic checks to prevent undue noise and movement are required for everyday maintenance. Routine monthly and annual maintenance activity are detailed in the manual.

There are over 1500 Haigh screens installed with strong current demand.
