Bredel, Qdos pumps reduce wastewater treatment costs at Indonesian plant

Indonesian company PT Sinde Budi Sentosa announced that it has employed Watson-Marlow Fluid Technology Group’s (WMFTG) Bredel and Qdos pumps to reduce downtime and limit costs in the treatment of wastewater from manufacturing operations.

The company, which specialises in the production of herbal products, uses large volumes of water to prepare the fruit it uses in producing its health and energy drinks.

This water is discharged to an on-site treatment plant, before being disposed of in the municipal waste system.

Using an air-operated double diaphragm (AODD) pump to feed wastewater to the filter press caused problems for PT Sinde, as soil and sand contained within the water would cause valves to stick and leak, requiring frequent stoppages for repair.

WMFTG specialists advised the company that it could improve water treatment, decrease downtime and cut AODD pump spares by installing a Bredel 40 peristaltic hose pump for the filter press feed duty.

The Bredel pump is able to handle viscous and abrasive slurries, pastes and sludge, with up to 80% solids in suspension, according to WMFTG.

In another process, an AODD pump was being used to dose chemicals into the wastewater for purification purposes. PT Sinde needed to know the exact amount of chemical being doses, however this was not possible with the AODD pump.

By switching to a Qdos chemical metering pump, the company was able to leverage WMFTG’s ReNu technology, which ensures accurate and repeatable flows while enabling quick and safe pumphead removal and replacement.

Through replacing these AODD pumps with WMFTG’s Bredel and Qdos pumps, PT Sinde was able to lower total cost of ownership across its wastewater operations.
