Structural Steelwork

Haigh provide standard and customised structural / mild steel galvanised support structures relating to inlet works.

The design service gives a full loading calculations, and delivers complicance with the stringent safety criteria relating in particular to access and maintenance of the installed equipment.

Pre-assembly at Haigh ensures a hassle free installation of the equipment on site, reducing risks associated with extensive on-site work.

Haigh can either manufacture in-house or work with key supply chain framework partners based on customer preference.

Control Systems

Utilising motor control centres or single control panels, Haigh deliver the most appropriate control systems to complement the mechanical installation.

Various forms of instrumentation can be used for example ultrasonics, level probes, pressure transducers to best suit the installation.

Haigh systems can incorporate electronic control components from the main worldwide sector suppliers at the level of sophistication best suited to the application.

Macipump Mounting Toe

The Macipump mounting toe ensures that the off-line macerator is positioned in the optimal fashion for best performance.

An interlocked, operator friendly inspection hatch allows grit and stones to be flushed out of the toe as required during scheduled maintenance operations.

Distribution Tank

The Distribution Tank allows collection of flows from multiple sources, output to multiple independent process components, as well as built in fine grit settlement.

Macerated effluent is pumped into the tank where internal features allow denser grit material to settle into the discharge point, while the remaining material passes on for further treatment.

Automated valves control the process, allowing for a high level of flexibility in both the redundancy, capacity and performance of the system that the distribution tank is built into.

Capacities from 16 l/s to 96 l/s per unit are available as standard.

Inlet Box with Handrake Screen

A range of fabricated inlet boxed featuring

• Built in, pre-calculated, proven hydraulics
• Pre-tested at the manufacturer prior to delivery at site
• Integrated bypass facilities with manual bar raked screen
• Flanged inlet / outlet as required for pipeline mounting
• Compatible with ACE Screeners or ACE Bandscreen
• Numerous maintenance-friendly features

Capacities from 4 l/s to 250 l/s per unit available as standard.

Conditioning Tank

This fabricated tank allows the process medium to be presented to the macerators in the most efficient fashion, as well as allowing multiple maceration units to be applied for greater process capacity or improved system redundancy.

Undesireable items such as debris and stones settle out in a dedicated area with interlocked, easy to access hatch.

Additional grit settlement can also be added to the unit.

Biosolids Input Hoppers

A wide range of input hoppers are available to suit the maceration requirements and capacities of the particular application.

Featuring:

• Recirculation to further reduce the particle size
• Level sensing via Ultrasonics or Inbuilt pressure sensors
• Cleaning ports
• Pre-maceration shredder mounting points
• Optimised internal profiling to ensure efficient and consistent maceration
• Batch or Continuous capabilities
• Integrated bunding available for spillage containment

Manual Stone and Grit Trap

A simple range of modules to collect stones and coarse grit for manual removal

Capacities from 2 l/s to 150 l/s per unit.

Designed for straightforward pipeline installation with flanged intlet and outlet connections.

Effluent velocity is slowed down as it passes through the module, settling out stones, coarse grit such that they can be periodically raked up a slope for disposal.

Simple method for protecting downstream equipment

Launder Channel Stone and Grit Trap

Automated trap to collect stones and coarse grit contained within process solids.

• Designed for launder channel installation with flanged inlet and outlet connections.
• Integrated actuated penstocks
• Integrated bypass channel for use while grit removal is in place

Standard capacity from 2 l/s to 40 l/s per launder trough.

Significantly improves downstream process reliability and lifespan.
