Containerized Dewatering Units from Elgin Separation Solutions are designed to be mobile and compact. They incorporate sophisticated graphical user interfaces, chemical additive injection systems, an ESS-1450HD2 or ESS-1967HD2 decanter centrifuge and inline mixer systems. By using polymer hydration manifolds, the polymer-enhanced flocculation of colloidal and ultrafine drilled solids can be efficiently removed with a decanter centrifuge, maximizing fluid recovery, lowering overall mud costs as well as disposal and transportation expenses. With a zero-discharge or closed-loop system, rigs can operate without mud pits, reducing the location footprint and environmental impact. 281/261-5778; www.elginseparationsolutions.com.
