AN INTRODUCTION TO SLUDGE HANDLING, TREATMENT AND DISPOSAL 1. GENERAL CONSIDERATIONS. Sludge, or residual solids, is the end product of wastewater treatment, whether biological or physical/chemical treatment. Primary sludge is from 3 to 6 percent solids. Treatment objectives are reduction of the sludge
the new primary sludge screening facility, and then into the screened primary sludge storage tank. An additional 5 L/s of scum will be intermittently fed into the line at the existing scum tie in point, 170 m downstream from the furthest primary sludge pump. x Flow Case 2 as per flow case 1, however via a
Apr 13, 20190183;32;Pumps play a main role in water amp; wastewater treatment plants and pumping stations, Ease of maintenance amp; repair are an important consideration for those responsible for keeping pumps in good working condition, Pumps in pumping stations get waste from its source to the treatment plant, pumps are used to move influent, raw water, primary sludge, secondary sludge amp; return activated
Entangled materials from digesters clog up sludge pumps and block mixers unless they are protected by a shredder. The XRipper wastewater grinder shreds and reduces entanglements and foreign matter like wood or plastic parts to an easy to handle size. This protects pumps from damage and clogging and ensures pipelines remain free.

Sludge Pumping amp; Treatment. High organic solids content in treatment plant processes. As wastewater treatment plants become larger and more sophisticated, so do the demands for handling large amounts of sludge, which is an expensive and complex operation. Pumps have got to handle high solids concentrations and are expected to provide
Recessed Impeller Pump for grit, primary sludge, digested sludge, scum; Hayward Gordon. Hayward Gordon TORUS174; Recessed Impeller pump is a centrifugal pump with a radial impeller recessed into the rear section of the volute, out of the path of the solids being pumped.This impeller uses about 15 percent of the fluid being pumped to create a torus or vortex thus adding energy to the pumped
The Multicrusher was installed on the suction side of the two primary sludge pumps which transfer the sludge alternately. Operating safely chopping performance and the reasonable wear parts were decisive in convincing the waste water treatment operator. Since the Multicrusher was installed, the primary sludge pumps have been running smoothly.
May 22, 20120183;32;Unlike a centrifugal pump, a PC pump can maintain flow rate regardless of pressure. But as sludge density increases, maximum allowable speed decreases. To reduce the wear rate on expensive components like the rotor and stator, pump speed should be lowered depending on how much abrasive solids like sand or grits are in the sludge.
RAM Pumps by EMS Filter Press Feed Pumps/Grit Removal/Primary Sludge Transfer Pumps/Food Waste Pumps. Often referred to as plunger, reciprocating or piston pumps, EMS RAM PUMPS offer a greater suction lift for dredging and pumping sewage, waste
Screw Centrifugal Pumps, Chopper Pumps, Prerotation Pump Systems, Grit and Sludge Vortex Pumps, Self priming Pumps, Hydrogritter Separators VISIT WEBSITE WEMCO is the market leading US brand for vortex and screw impeller pumps in wastewater, solids and high grit applications, especially among municipal customers.
Rotary lobe pumps can handle higher abrasiveness Because the lobes dont touch, abrasion will not affect operation as greatly as the always touching gears in a gear pump. Rotary lobe pumps can often handle higher pressures Pump shaft support bearings are located in the gearbox, and since
The WEMCO174; HYDROGRITTER174; has three major components a pump, a cyclone separator/concentrator, and a dewatering/washing classifier. The pump pulls grit from the grit chamber or other source and feeds it to the cyclone separator. The grit is then captured/concentrated and discharged into the spiral classifier, where it is washed and dewatered.
Jan 20, 20190183;32;Primary sludge pumps are typically used in municipal Wastewater treatment facilities to transfer digested sewage and sludge. This is a broad pump category that encompasses positive displacement pumps to pump sludge in ranges usually up to about 500 GPM. The choices of pumps vary from double diaphragm pumps, plunger pumps, double disc pumps
pump time per sump. (See Figure 1) With the success of the installations at Greenway, the same strategy has been implemented at all of the Citys waste water treatment plants. Value of online instrumentation There are some observations that would be very difficult to understand without online instrumentation. Figure 2 shows the primary sludge
Polymers are often shear sensitive and progressing cavity pumps reduce the particle size leading to increase chemical usage; Sludges often have a high grit content creating abrasive wear problem for many pumps with rotary pumps suffering from ragging problems on primary sludge.
The Primary Sludge Pump combines the performance features of a positive displacement pump and the principle of Induced Flow to provide superior versatility in fluids handling. Based on a Free Disc technology, the Primary Sludge Pump utilizes a unique principle of operation where the discs perform the duties of both diaphragm and
