Enhancing Drilling Efficiency: Introducing Our High-Capacity Saline Water Filtration Unit

 In the demanding environment of oilfield operations, maintaining the integrity of drilling fluids is paramount. We are proud to introduce our robust Saline Water Filtration Unit, a critical component designed for integration into complete solids control systems. This unit is engineered to deliver reliable, high-volume filtration essential for modern drilling projects.

Designed for Performance and Reliability:

This skid-mounted unit features a two-stage filtration process to ensure fluid clarity. It utilizes a primary basket filter and a secondary bag filter to achieve a final filtration precision of 2 microns, protecting downstream equipment. With a guaranteed flow rate exceeding 1 cubic meter per minute (250 GPM), it meets the high-demand requirements of active drilling sites.

Built for Safety and Harsh Conditions:

Understanding the operational environment, the unit is constructed with durability in mind:

Material: Major components are made from corrosion-resistant 304 Stainless Steel.

Safety Compliance: The entire electrical system, including the 15kW pump motor and control cabinet, is certified for hazardous areas (Exd IIB T4) and carries international ATEX/IECEx certifications.

Rugged Design: It comes with integrated lifting lugs and forklift pockets for easy transport and positioning on-site.

Ideal for:

This filtration unit is a perfect fit for land and offshore drilling rigs, as well as other industrial applications requiring high-purity saline water filtration.

drilling fluid processing glossary U

Ultra-fine solids. Particles whose diameter is between 2 and 44 microns.

Ultra-fine wire cloth. A group of industrial wire cloth specifications with lighter than normal wire. The wire diameter of this grade produces the highest percentage of open area of all other grades for any specific mesh size. This cloth is used in multiple layer screens. See: market grade cloth, mill grade cloth, tensile bolting cloth, and calendered.

Ultraviolet light. Light waves shorter than the visible blue and violet waves of the spectrum. Crude oil, colored distillates, residium, a few drilling-fluid additives, and certain minerals and chemicals fluorescein the presence of ultraviolet light. These substances, when present in drilling fluid, may cause the drilling fluid to fluoresce.

Unbalanced elliptical motion. An elliptical motion of a shale shaker screen such that the ellipse axes at the feed end are tilted toward the discharge end of the screen and the ellipse axes at the discharge end are tilted toward the feed end. Usually these screens are tilted downward to assist solids removal from the end of the screen. The vibrator is usually located above the center of gravity of the shaker basket.

Underflow. (1) Centrifugal separators: the discharge stream from centrifugal separators that contains a higher percentage of solids than does the feed. (2) Screen separators: the discharge stream from screen separators that contains a lower percentage of solids than does the feed.

Underflow header. A pipe, tube, or conduit into which two or more hydrocyclones discharge their underflow.

Underflow opening. See: apex, apex valve.

Undersize solids particles. (1) Particles, in a given situation, that will pass through the mesh of the screen in use. (2) Particles, in a given situation, that will remain with the liquid phase when subjected to centrifugal force.


Underslung. Field terminology denoting that the support ribs for the shaker screen are located above the screen surface. See: overslung.
