Remove more, finer grit to protect downstream equipment, increase plant efficiency and cut maintenance and repair costs.

The HeadCell® is a stacked tray grit, sand and solids separator that captures and retains 95% of all grit 75 µm and larger - guaranteed.

With a small footprint, no electrical requirements and no moving parts the HeadCell® delivers exceptional and economical solids removal for small, medium or large wastewater treatment works (WwTWs), helping them to maintain treatment effectiveness and cut operation and maintenance costs.

The unique stacked tray design provides the surface area required for outstanding performance with a small footprint, enabling treatment capacity increases using existing space, and its durable design ensures long component life with mininal wear and grease build-up, even under challenging operating conditions.

Enabling plants to meet stringent environmental requirements with less odour, the HeadCell® is the ultimate grit removal solution for new plants as well as representing a value-for-money retrofit option for grit removal upgrades. For new headworks grit control systems, the HeadCell® can be installed in a poured-in-place concrete basin above or at grade, with a footprint much smaller than conventional grit removal systems.

Applications

  • Improved wastewater management

  • New wastewater treatment plants

  • Treatment plant retrofits

  • Grit and / or sediment removal for potable water applications

  • Industrial effluent degritting

Our specialist inlet works services team

M&N is Hydro International's UK Wastewater Services (UKWWS) team. With around 140 dedicated service professionals operating from five regional offices across the UK, our UKWWS team is the country’s largest provider of inlet works support, giving critical assistance to wastewater treatment plant owners and operators 24 hours a day, 365 days a year.

Delivering reliable, cost-effective inlet works servicing, maintenance, refurbishment, equipment hire, parts and spares, the UKWWS team provides water companies with greater opportunities to improve operational asset management, drive efficiencies, reduce manual intervention and extend the lifetimes of their key treatment assets.

The HeadCell® captures fine particles due to the very large surface area and short settling distances. Evenly split flow eliminates thermal short circuiting which reduces the performance of conventional grit basins, making the HeadCell® the ideal grit basin. The HeadCell® is a hydraulically driven forced vortex system which requires no moving parts to operate.

  1. The high efficiency flow distribution header evenly distributes influent over multiple conical trays.

  2. Tangential feed establishes a vortex flow pattern where solids settle into a boundary layer on each tray, and are swept down to the center underflow collection chamber.

  3. Settled solids are continuously pumped to a SlurryCup™, OpTeaCup™ or TeaCup® grit washing system and then on to a Grit Snail® dewatering escalator or can be sent to a Hydro GritCleanse™ combined washing and dewatering system.
