the power cost per thousand gallons is directly proportional to the cost per kilowatt hour (kwh) and pump head while inversely proportional to pump and motor efficiency. let’s compare the electrical costs for two different pumps. figures 2 and 3 show the power cost per thousand gallons pumped for two pumps.
along with the 1887 is has the best range of all the shotguns but requires a pump after every shot and this is were the problem comes in, it doesn't always kill in one hit. it will kill often in one hit due to the high power/range of the weapon but if it doesn't the pump can feel like an age between each shot, it'll usually equal your death.
indiana alone has spent at least $21 million on the cleanup thus far, or an average of about $500,000 per site, according an analysis of records by the associated press. and the work is nowhere
effluent with a total solids (ts) content <2 per cent is easily pumped with conventional centrifugal pumps. slurries with a ts content of 2 10 per cent ts can be pumped with various types of positive displacement pumps or specifically designed centrifugal pumps (i.e. chopper pumps). once sludge exceeds 15 per cent ts it is

in recent years, the energy generated by anaerobic digestion of sewage sludge has increased dramatically. this article looks at how seepex progressive cavity pumps for sludge transfer and mixing duties delivered lower sludge disposal costs, lower energy use and reduced maintenance overheads, energy
the equation computed for the capital cost of primary sedimentation was : log (cost) = o.233 log (area) 0.758 cost = dollars/square foot area = thousands of square feet digestion figure 6 shows the capital costs of sludge digestion. total cost for this process includes all heating, mixing and gas requirements, sludge pumps, concrete tank
