A member of ACT Engineer's dedicated field crew is collecting sediment samples using a vibracore sampling unit. A vibracore captures sediment samples from water-saturated sediment by liquifying the surrounding sediments which reduces friction, increases compression, and limits the disturbance to the collected sediment sample.   #FieldWork #Environmental #SedimentSampling

Angel Descent The need for accurate and undisturbed core samples has led to the development of this new coring method with controlled penetration speed, in order to obtain sediment samples with more accurate outcomes. Based on the water depth, this methodology, called “Angel Descent“, can be applied in different ways: in shallow water the corer is connected to a winch or a crane with variable speed control, while the piston is tied off to a fixed point on board with a very resistant rope; this rope runs down the length of the corer and attaches to the top of the piston. For deep waters has been designed a special winch: Carma® Winch. The elasticity of the cable will not, however, be insignificant, but this problem can finally be solved. Usually, the cable snaps back once released, after it stretches out due to the weight it sustains, depending on the depth of the job at hand. With this new method, the problem is solved because the mass of the corer – which weighs on the main cable – gradually, declines: the speed of the backlash of the main cable will be less than the speed of penetration of the coring tube in the seabed, thus allowing a much better result to be obtained.The method of controlled penetration speed can also be used in geotechnical or environmental studies, for example in the dating of undisturbed samples for determining the time-line of human affected events when dealing with environmental issues such as contamination and pollution.

An awesome example of a combination of the #Ro #waterfilter and #Ultrafilter system showcases #Greenaqua exceptional capacity in need of bottled water operators. The amazing creation is first that an 18 tons/hour Ultra Filtration system is to be introduced to the pre-treatment system of the water filter, which forms a multiple #pretreatmentfiltration before the Ro membranes, not merely the conventional sand filters, carbon filters, and the PP sediment filters. The extra Ultrafiltration system, as an extra pre-filtration, will protect further #Romembranes and elevate the shelf-life of the Ro membranes. Also, it is a holistic #waterfilter armed with an #ozonegenerator, UV System, and hygienic water tanks. https://lnkd.in/ga6qbbC5
