Pumps with extended service life for generating biogas from organic waste
When regular commercial pumps are used to process organic waste, they typically wear out after only a short period of time. Liquids pumped under these conditions attack pumps from two different angles: first with highly abrasive additives and second with liquids that have highly fluctuating pH values and therefore a high level of chemical aggressiveness. These conditions are very tough on seals ...

KTC EDIBLES - Case Study
DAF system to separate oils from their effluent was unsuccessful. Thus, meeting compliance was a challenge. Off-spec oily water was tank-farmed which had become unmanageable. Discharge limit of 1000 mg/l COD was often exceeded by a factor of 4-5 times. The Water Authority was scheduled to terminate discharge if no solution presented. The effluent from five sources was piped to a centralized ...

Allweiler Peristaltic Pumps: an ingenious solution for biogas plants
Installations and plants used to process biomass for the production of biofuels must be capable of handling difficult conditions. For example, intermediate products in the production of biodiesel exhibit a high level of chemical aggressiveness. Accordingly, pumps, pipe connections, and fittings must be capable of resisting these demanding conditions. In addition, waste products usually contain a ...

Transportation of digested sludges over extreme distances
Sludge is a residual product of sewage treatment that, as a rule, is digested and concentrated. In larger processing plants, it is dehydrated, partially dried and subsequently utilised in other processes. This usually takes the form of incineration and subsequent use as an additive to building materials by the cement industry. In the sewage treatment plant (STP) of the local authorities ...

Sioux Falls, Verder Pumps - Case Study
The Sioux Falls Water Purification Plant in South Dakota USA, had always relied on gravity to feed slaked lime slurry to their softening basins. In 2009, the staff decided to give gravity a helping hand by trialing a pump to move the slurry more effectively. Lime slurry is a dense product to transfer with a high solid content of up to 35%. Due to the slurry’s abrasive nature which causes ...

Less and More : Why You Should Pump Slurries with a Peristaltic Pump
LESS WATER Peristaltic Pumps Use Less Water Hose pumps can circulate slurry SGs of 1.6 to 1.8 or up to 80% solid content. The traditional centrifugal pump loses efficiency when the slurry SG reaches 1.3 or 30% solids. With this limitation, slurry pumps have significant process water demands : on a plant processing 70 tonnes of ore per hour, every time a hose pump replaces a process slurry pump, ...
