replacement tank”.
This is where Hayes GFS came in; experts in the installation and refurbishment of glass-fused-to- steel tanks. The Devizes-based tank specialist suggested Glatfelter try an externally-mounted mixer from Landia.
“Having the mixer on the outside of the tank was always going to be so much better for us”, continued Howard Williams, “but to be perfectly honest, we were a little sceptical about how any mixer could deal with the range of different fibres used in our manufacturing process, where the dewatering rate can vary significantly. Our old internal mixer couldn’t stop some fibres from settling in the middle of the tank, which with the significant effluent volume we handle, led to a small mountain building up in the centre. The mixer became completely blocked and the crust was so thick it wouldn’t disperse, so several times over the years, we had to drain everything down and pay for contractors with cranes to come in and dig it all out.
Four years on, Williams describes the installation of the 11kW Jet Mix system as a ‘resounding success’; so much so that Glatfelter decided to invest in three more Landia mixers. Two further JetMix systems now serve a 1500m3 vessel, with another JetMix installed in a 500m3 unit. Both containers work as balancing tanks before the wastewater goes on
to other treatment processes at the Gloucestershire plant, including two DAF systems. For each tank, the pump outlets are horizontal, allowing mixing to continue, even if tank levels are low.
‘We get excellent performance from the Landia mixers, which run almost 24/7’.
“Investing again in Landia was a no brainer”, added Williams.
“Despite all the variables in our wastewater, we
get excellent performance from the Landia mixers, which run almost 24/7. We also benefit from their professional in-house service team who come to our facility in Lydney to carry out preventative maintenance. All of the health and safety issues have been removed, including working in confined spaces. Despite the high pH levels, the first Landia mixer still looks in very good condition – four years on from its installation. Overall, they are excellent value for money”.
New Super Nova pump range
Offering unparalleled volumetric efficiency for a rotary lobe pump, Borger has launched the new, BLUELine Nova range.
Designed with a special, one-piece DIUS rotor, the BLUEline Nova (available in six sizes, with flow rates up to 110 m³/h) provides almost pulsation- free pumping at pressures up to 12 bar.

This new high-tech Nova range can also be supplied without casing liners for CIP (Cleaning in Place) and SIP (Sterilisation in Place) applications – or with liners for the pumping of abrasive media containing solids.
The wide sealing surfaces of the screw-profile
rotor prevent any backflow of the medium – and the large seal chamber of the Nova rotary lobe pump provides space for various sealing systems.
Compact, due to the elimination of the coupling, this new Borger pump range can also be supplied without a base frame.
