Centrifuge capacity in oilfield drilling mud applications

Centrifuge capacity in oilfield drilling mud applications

A problem for everyone who uses centrifuges in the oil field is judging the centrifuge’s capacity, particularly in unweighted muds. Unfortunately the general attitude of the industry is to give hydraulic capacity (how much feed a centrifuge can physically swallow) without regard to the quality of performance a centrifuge can give at its “rated capacity”. For 50 years, centrifuge leasing companies have claimed higher and higher flow rates for essentially the same size centrifuges. In effect,…

Benefits of using a centrifuge for dairy cow and swine (pig) manure separations

Benefits of using a centrifuge for dairy cow and swine (pig) manure separations

There are several benefits to using centrifuges when compared to other separation technologies currently used for fresh-flush dairy cow and swine (pig) manure dewatering applications.  These benefits include:  Properly optimized centrifuges typically remove 70-85% of suspended solids in fresh flushed swine and dairy wastewater. Centrifuges have the capability to separate manure solids down to as little as 25 microns in particle size.  By comparison, most screw press technologies are limited…

Why purchase a reconditioned decanter, disk-stack, or basket centrifuge when you can buy new?

Why purchase a reconditioned decanter, disk-stack, or basket centrifuge when you can buy new?

One should consider several advantages to purchasing reconditioned-used centrifuges when compared to purchase of a new centrifuge:  Cost savings.  Reconditioned centrifuges typically cost 30% – 60% less than a brand-new comparable model.  As most centrifuges are built specific to a particular process and not mass-produced, a customer can realize savings of tens of thousands of dollars when compared to purchase of a new centrifuge.  Lead time.  Deliveries on reconditioned centrifuges…
