SEPTAGE RECEIVING STATIONS COMBY PLANTS RCT3 Compact Systems for pre-treatment of cesspool-interceptor septage MACHINE DESCRIPTION The septage acceptance unit is a system studied to receive and mechanically pre-treat effluents from cesspools with a single compact unit. The sludges, discharged from tanker trucks, are filtrate to remove large particles, thus sand is settled and washed, finally grease and oily particles are floated and scraped from the sludge surface. The conditioned effluent is afterwards discharged into the biological wastewater treatment plant. WORKING LOGIC FOR COMBY PLANTS RCT3 Tanker trucks get connected to the unit through a flex hose DN.100 and clamped by a quick spherical connection. Solid large particles included in the waste are captured and removed by the inlet fine screw screen. The screw removes and compacts the screenings before discharge. Along the conveying section is installed a washing system consisting of a set of nozzles where pressurised water is sprayed into the screenings themselves. The washing system allows to remove fecal matter from the screenings discharging a neat solid which can be landfilled without bothering of smells or leakages. At the discharge a built-in compactor is installed reducing the screenings volume by up to 50%. Once screened the sludge enters the aerated sedimentation tank where sand deposits on the bottom of the tank, while organics are kept in suspension by the air injection. The coarse air bubbles allow to wash out the sand and allows the separation of sand having a reduced organic content. The extraction screw removes and discharges the sand into the sand bin. The RCT3 type is also equipped with a grease and oil skimmer. A travelling floating skimmer is installed in a side channel where grease are concentrate by the air pattern and segregate through a reverse Thomson-like baffle. The skimmer removes on a timer the floating parts and discharges them through a discharge pipe. MAIN ADVANTAGES FOR COMBY PLANTS RCT3 - No leaks, smells or aerosols generated by the system. - No drives in contact with the sludge. - Compact design and small footprint. - No concrete casting required. - Low operation and maintenance costs. - Low costs for installation and erection. - Excellent screening performance with up to 52% solids capture ratio. GENERAL DIMENSION DATA FOR COMBY PLANTS RCT3 Here we provide some information of a technical nature for this type of screens: - Filtration with 6 mm perforated screen. - Removal and conveying of screenings to the discharge point with a single drive. - Volume reduction of screenings up to 50%. - Removal of sand (200 micron or bigger) up to 90%. - Floating grease and oils reclaim. - Effective drainage of the screenings along the conveying section combined with a compaction section for more volume reduction and water removal. - Washing of screenings performed by the REMSPRAY integrated system using 3 independent washing cycles.
