Sludge pump motor control systems shall include time clocks and valve activators for regulating the duration and sequencing of sludge removal. Gravity flow systems should have back-up pumping capabilities.
Shipboard transfer pumps can frequently provide the necessary energy to produce emulsified sludges during normal fuel transfers. These emulsified sludges can cause rapid fouling and shutdown of centrifugal purifiers, clogging of strainers and filters in the fuel oil system and rapid fouling if burned in the engine.
A typical application on board ships or vessels for marine sludge oil pump is for the residue from purifiers after the lube and fuel oil have been purified.

The EPC 60 controller provides many alarm functions, including alarms for low oil pressure, high sludge tank level (if the optional sludge removal kit is included) and power failure. Additional functions are available for a vibration alarm when the optional vibration sensor is fitted. System layout Low-wear mechanical platform
Jul 16, 2020 For normal oil, one stage purification is enough, but for oil containing heavy sludge or catalyst mixture, multiple purifiers are used in either parallel (preferred) or series to get better results. The new age purifiers/ clarifiers are automatically de-sludged at a regular interval (by use of timer and controllers).
Mar 24, 2011 Slop Tank. The refinery has two groups of slop tanks. The first group is used to recover oil from the API separator, and the second group is located in the tank farm (see Figure 6-49 ). The oil separation from wastewater in these tanks depends on the physical process. The contents of the tanks are heated to 66C over a period of three hours.
Jan 31, 2007 Proton Pump Inhibitor May Reduce Gallbladder Function. I have come upon a couple of disturbing articles concerning the effect of Proton Pump Inhibitor therapy on gall bladder function resulting in false positive HIDA scan results. Apparently gall bladder motility is effected by PPIs and as a result you may develop symptoms to gall bladder ...
The piston pump can be defined as it is a positive displacement pump. These pumps use a piston, diaphragm, otherwise plunger for moving liquids. These pumps use check valves as the input and output valves. The general piston-pump is a rotary pump which uses a wheel or revolving shaft for operating the piston.
Feb 14, 2018 The centrifugal purifier uses the principle of density difference to separate water and other contaminants from oil mixture. While the separating force of these mixtures under gravity separation is defined by formula Fs /6*D3* (w-o)*g. Now by replacing gravity ( g ) with centrifugal force 2 r we able to simply increases the rate of ...

Our DAF units provide a separate sludge thickening skimmer and sludge removal scraper with variable frequency drives, enabling the speed of these two units ...
Oct 29, 2009 A juinor engineer should know thoroughly about the placement of various machines even before going on board and this is taught during pre-sea training and other academic courses. Here is an aid to gain more of this knowledge and the next few articles will provide a birds eye view of the various platforms which form a central part of the machinery
The trend today is towards the use of the activated sludge process instead of trickling filters. The activated sludge process speeds up the work of the bacteria by bringing air and sludge heavily laden with bacteria into close contact with sewage. After the sewage leaves the settling tank in the primary stage, it is pumped into an aeration tank,
steps (l) sludge mobilization, (2) mixing and characterization, (3) solidification and stabilization, and ( 4) packaging and shipping. The Sludge Mobilization System will add jet mixers to the MVSTs and use water or supernate to mobilize the sludge (e.g., diluted from
activated sludge. Oxygen is provided in the aeration tank either by blowers and diffusers or by a mechanical mixing process. A variation of the activated sludge process that is becoming more popular is known as Sequential Batch Reactors (SBRs). This process differs from the more conventional activated sludge systems in that it also uses
Sludge removed from the waste water treatment process is aerobically digested, a biological process that serves two functions. Aerobic digestion further reduces both the organic solids content of the sludge and the number of pathogenic micro-organisms contained in the sludge. The sludge is thus stabilized and less odorous.
