Pilots

Three sites, three kinds of water.

Every Tarn install starts with a pilot skid on the site's own water for four weeks. These are three of them.

Pilot 01 · A brewery in Kent

Rinse water back into the wash.

A brewery running two packaging lines sent its clean-in-place rinses and bottle wash to drain, about 140 m³ a day. Tarn took the rinse water, removed the label pulp and the yeast, and sent it back to the first rinse of the next cycle.

Pilot 02 · A dye house in Leicestershire

Clear enough to rinse the next batch.

A dye house rinsing knitted fabric used 260 m³ of mains water a day, most of it for the rinses after dyeing. Tarn held back the fibres and the colour and returned water clear enough for the next rinse.

Pilot 03 · A plating line in the West Midlands

The metals held back, the water returned.

A zinc plating line ran its rinse tanks on a constant overflow. Tarn treated the overflow, held the metals back in the concentrate for recovery, and returned the water to the rinse tanks.
