» The situation Mechanical pretreatment is required for both municipal and industrial wastewater in order to remove coarse materials and separate floating, settling and suspended solids. Depending on the method of wastewater treatment that is applied the mechanical pretreatment system must fulfil different requirements in terms of separation efficiency. Special plants which operate according to the MBR principle put the highest demands on the mechanical pretreatment system as all coarse material needs to be removed. A cost-efficient solution must not only achieve the requested separation...

The characteristic feature of the HUBER Drum Screen LIQUID is its screen basket which is horizontally installed in the channel or in a tank. The wastewater to be treated flows through the basket from inside to outside. Whilst the wastewater flows through the open front into the screen basket, solids are retained within the drum. A special sealing between the channel and the front-end screen basket opening prevents unscreened wastewater from passing through the screen basket. The solids settling on the drum surface lead to gradual blinding of the surface. As a result, the water level...

➤ High pressure cleaning ➤ ➤ WASTE WATER Solutions For preventive basket cleaning an innovative automatic high pressure system can be integrated as an option. The spray nozzle head rotates automatically due to the water pressure and moves linearly along the full length of the screen basket to clean the complete basket thoroughly and efficiently. Water demand and operator attendance are reduced to a minimum. Automatic high pressure cleaning system of the HUBER Drum Screen LIQUID Every system is only as good as its sealing system in the inlet of the machine. A special PU sealing is therefore...

➤ Application example: load reduction in the biological treatment stage ➤ ➤ WASTE WATER Solutions Due to its excellent separation efficiency the HUBER Drum Screen LIQUID mesh is very well suited to be used to reduce the solids loads in the biological treatment stage. A HUBER Drum Screen LIQUID mesh with 0.3 mm mesh size for example achieves reduction rates of up to 60% for filterable solids (AFS) and up to 40% for chemical oxygen demand (COD). Peak loads can thus be balanced, aeration energy in the aerobic treatment stage can be saved and the capacity of the sewage treatment plant...
