The Septic Tank. The septic tank was patented in London around 1900. Webster's Dictionary defines the septic tank as "a tank in which waste matter is decomposed through bacterial action." The modern septic tank is a watertight box usually made of precast concrete, concrete blocks, or …
Wastewater treatment - Wastewater treatment - Sludge treatment and disposal: The residue that accumulates in sewage treatment plants is called sludge (or biosolids). Sewage sludge is the solid, semisolid, or slurry residual material that is produced as a by-product of wastewater treatment processes. This residue is commonly classified as primary and secondary sludge.

Biosolids Technology Fact Sheet Belt Filter Press DESCRIPTION Belt filter presses are used to remove water from liquid wastewater residuals and produce a non-liquid material referred to as "cake". Dewatered residuals, or cake, vary in consistency from that of custard to moist soil. Dewatering serves the following purposes:
Find a local oil disposal company and get a rate for disposal and the transportation cost. The average cost is $1 to $2 per gallon of waste oil. It's hard to find anyone willing to buy the sludge due to possible contamination. The cost of disposing of an old oil tank is $200 to $300. This does not include transport if the disposal location is far.

In the Lake Tahoe estimate for recalcination, only the cost of the recalcined sludge was included and the cost of burning the waste lime sludge with the organic waste sludge was included in the cost of the conventional processes. The policy used here will be to charge the cost of burning the waste lime sludge to the lime recal- cination process.
All permit requirements were routinely met. Sludge was dredged from the second pond cell once every 3 to 5 years at a cost of $150,000.00 per event. A previous dredging event damaged the liner, costing $125,000.00 to repair (cost is for the repair‐damaged area only). The Science behind Blue Frog Technology to Bio-dredge In Situ

Sewage sludge is also a good base medium for digesting with other organic residuals [biowastes]. It was sewage collection and treatment (public health engineering) that cut waterborne disease and increased life expectancy in towns and cities in the mid-19th century, so it is no surprise that untreated sewage sludge contains pathogens

Total Cost of Ownership (TCO) for Slurry Pumps The concept of Total Cost of Ownership (TCO) is not new to the industrial world, and has been cited as far back as the Napoleonic era, when his engineers would design cannons to increase availability and reduce maintenance between battles.
Sewage, sludge weighs 0.721 gram per cubic centimeter or 721 kilogram per cubic meter, i.e. density of sewage, sludge is equal to 721 kg/m³. In Imperial or US customary measurement system, the density is equal to 45 pound per cubic foot [lb/ft³], or 0.417 ounce per cubic inch [oz/inch³] .
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.
