Weirs Applications

Coastal & Nearshore For coastal and nearshore use DESMI provides the well known Ro-Boom product but in smaller sizes whilst maintaining the integrity of the larger product offerings. Alternatively, you may want to consider SPI or a lighter weight boom if there are deployment and recovery considerations or restrictions. Under these circumstances, the Troilboom AF (Air Filled) offers a light weight rapid response solution. It is manufactured as standard in bright orange polyurethane fabric offering durability and strength. Top tension wires are also available to enhance performance. A wide range of combination skimmers have been developed for the coastal environment. These include weir, brush, disc and belt recovery systems with on-board pumps. This results in systems being able to recover a wide range of oils including emulsions and weathered compounds. An example of this is the Terminator skimmer system.

For oil spill response in beach and shoreline environments DESMI offers a whole host of equipment to handle any eventuality. The smaller sizes of Ro-Boom and Ro-Beach are unequalled in application and robustness while the range of lightweight Troilbooms can meet the lower cost expectations. In addition the famous Termite and Mini-Max weir skimmers are proven performers in recovery. Recovery systems are also available in vacuum designs from the well-known Ro-Vac to the highly portable Ro-Vac Mini – the latter even with its own transfer pump system to divert the pollutant. Although the Ro-Tank can also be used on land or the back of a trailer, the Troil range of open top tanks offer the perfect solution for storage of the recovered oil. These tanks are very lightweight and need no special tools to erect. The tanks offer a wide selection of capacities – indeed , the smaller units are ideal for decontamination duties.

The manufacture of cement combines a variety of raw ingredients such as limestone, clay or shale. These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions. The resulting raw mix is fed into a cement kiln which heats them to extremely high temperatures of about 1400 C to 1500 C. The abrasiveness of the material is a major factor on the wear of equipment and the extreme high temperatures of the process require specialized equipment.

Decanter centrifuge is used as the 4th phase solids control equipment after shaker, desander and desilter. The centrifuge suck the mud from the compartment receiving the discharge from the desilters and mud cleaners, and the returned stream is directed to the next compartment downstream. The use of decanter centrifuge with the drilling mud is (1) removal fine solids from unweighted fluids (2) selection separation of colloidal and ultra-fine solids from weighted fluids to improve their flow properties.
