Finlay's produces greener tea

Established over 250 years ago, Finlay's produces decaffeinated and speciality teas. Pressure from local water authorities to reduce biological oxygen demand (BOD) levels in the waste water discharged from its decaffeination process led Finlay's to sieving and filtration specialist Russell Finex.

With a lot of fine solids in its waste water, Finlay's needed to reduce oversize contamination to help bring BOD levels down. It also wanted to cut maintenance costs.

After successful onsite and offsite tests, Finlay's realised the Russell Finex Liquid Solid Separator was exactly what it was looking for. The centrifugal action of the Liquid Solid Separator removes many potential contaminants including leaf tea and tea fines from the discharge water. By catching this oversize contamination before it is released, Finlay's has significantly reduced the chance of incurring penalty fines from local water authorities and cut BOD levels.

Finlay's can now re-use its waste water and pump it back into the manufacturing process, minimising the use of town water for the decaffeination process.
