24 Water / Wastewater TALKING POINT Phase 3 of Ocean Cleanup Project extends to Indian Ocean
In the ongoing fi ght against the perils of marine plastic pollution, the Indian Ocean has become a focal point for innovative conservation eff orts, spearheaded by The Ocean Cleanup’s latest advancement, System 03. This initiative is not merely a continuation but a signifi cant evolution in the quest to tackle the Great Pacifi c Garbage Patch (GPGP), heralding a new era in oceanic preservation.
System 03, the brainchild of The Ocean Cleanup, stands as a testament to human ingenuity and determination to protect our oceans. With a staggering wing length of 2.2 kilometers, this system is not only nearly triple the size of its predecessor, System 002, but also a crucial step forward in addressing the vast expanse of the GPGP, an area three times the size of France. This ambitious endeavor is crucial, considering the bulk of fl oating plastic debris resides not on the surface but approximately 4 meters beneath, a challenge System 03 is uniquely equipped to tackle through its extended screen depth, ensuring a signifi cant capture of submerged plastics.
The journey to deploy System 03 is no small feat, involving a fi ve-day voyage across the ocean. Accompanied by two vessels, the Maersk Tender and the Maersk Trader, this system is towed at a slow pace, carefully navigating through the densest areas of plastic accumulation. This meticulous approach, aided by artifi cial intelligence and precise monitoring data, maximizes the effi ciency of plastic capture.
Upon reaching its full capacity, the collected debris is transferred to one of the vessels, where it undergoes segregation and packaging, ready to be repurposed. This cycle of collection and recycling embodies The Ocean Cleanup’s vision for sustainability, transforming oceanic
waste into valuable resources. Notable collaborations, such as with Kia to incorporate GPGP-extracted plastic into new electric vehicles, exemplify the project’s innovative approach to recycling.
System 03 also signifi es a leap in ensuring the safety of marine life, incorporating the Marine Animal Safety Hatch (MASH) and advanced camera systems to monitor and protect ocean inhabitants caught within the system inadvertently. This attention to ecological preservation underscores The Ocean Cleanup’s commitment to not only cleanse the oceans of plastic but to do so with minimal impact on marine ecosystems.
The evolution from System 02 to System 03 refl ects a journey of learning and improvement, with each iteration enhancing effi ciency, safety, and eff ectiveness. The broader vision encompasses a fl eet of such systems, working in unison to not just mitigate but eradicate the plastic pollution scourging the GPGP.
In parallel to tackling the open seas, The Ocean Cleanup’s strategy extends to preventing plastic pollution at its source. Through the deployment of Interceptor systems in rivers, the project addresses the dual challenge of cleaning up existing marine pollution while stemming the fl ow of plastic from land to sea. This holistic approach highlights the necessity of addressing both ends of the pollution spectrum.
The collaboration with Bharat Clean Rivers Foundation marks a signifi cant milestone in The Ocean Cleanup’s expansion into the Indian Ocean region, focusing on Mumbai’s rivers as a primary source of plastic emissions. This partnership embodies a synergy of research, technology, and local
knowledge, aiming to devise scalable solutions to intercept plastic pollution before it reaches the oceans. The initiative in Mumbai is not just a local eff ort but a model for global application, demonstrating that through collaboration, innovation, and a data-driven approach, the tide against oceanic plastic pollution can indeed be turned.
As The Ocean Cleanup embarks on this monumental journey with System 03 and its river interception projects, the world watches with bated breath. The success of these initiatives represents more than just the removal of plastic from our oceans; it symbolizes a beacon of hope, a proof of concept that human intervention can indeed restore the health of our planet’s most vital ecosystems. With the unwavering support of partners, donors, and the global community, the dream of pristine oceans is closer to reality than ever before.
Accurate fl ow, level and temperature measurement in a single device for large-scale water chillers
Water engineers, technicians and contractors responsible for large-scale chilled water systems providing refrigerated water will fi nd the dependable dual-alarm FLT93S Series Flow Switch from Fluid Components International (FCI) provides exceptional system monitoring, alarming and switching to keep their cooled water fl owing while avoiding equipment damage and system downtime.
These large, chilled water systems are frequently found in district energy systems. They provide building owners with centralised cooling, and heating too, which serves city business districts, medical and corporate campuses, universities or convention centres by providing more economical, climate-friendly heating, ventilation and air conditioning (HVAC).
No matter the type of district energy plant, FCI’s FLT93S Flow Switch provides liquid fl ow, level and/or temperature monitoring and switching as the chilled or hot water passes from the plant through a network of pipes to the district’s buildings. Once the energy transfer of cooled or heated water occurs at each building, any remaining water fl ows back to the plant for reuse.
FCI’s dual alarm FLT93S Flow Switch Series reliably monitors the fl ow and temperature of liquids, gases, slurries and more. These fl ow switches are valuable where unexpected reductions in liquid or other media fl ow rates leave chillers, pumps and other types of equipment, which are sensitive to dry running conditions, ready to grind to a halt, which can result in process shutdowns that require trouble-shooting, extensive repairs or even equipment replacement.
When Alarm 1 occurs, the FLT93S Switch has detected a liquid low fl ow situation anywhere between 0.003 to 0.9 meters per second (0.01 and 3 feet per second). The Alarm 1 low fl ow alarm can be regarded as a pre-warning signal for the control system or the operator. The system or operator can then decide to keep the water refrigeration system running or decide to shut it down for inspection and potential repair.
If Alarm 2 occurs, it is because the water feed line is either running below the minimum required liquid fl ow rate or actually running dry, this condition is an emergency signal to shut down the refrigeration system immediately. In these situations, equipment damage can occur very quickly. Using a fl ow switch prevents serious or permanent damage to the equipment that will then defi nitely require costly repairs or even replacement.
The advanced FLT93S Flow Switch is a dual-function instrument that indicates both fl ow and temperature, and/or level sensing in a single device. Dual 6A relay outputs are standard and are assignable to fl ow, level or temperature. The FLT93S Switch can be specifi ed in either insertion or inline styles for pipe or tube installation.
FCI fl ow switches are electronic fl ow switches that apply thermal dispersion fl ow measurement technology to provide a highly accurate and repeatable fl ow rate to achieve highly reliable and repeatable setpoint detection. When the fl ow rate is above (high fl ow) or below (low fl ow) the user-defi ned setpoint, electronic fl ow switches trigger an output signal, typically a relay or transistor, to change state.
FCI is the only thermal fl ow switch manufacturer providing sensor temperature compensation to ensure set point accuracy for process temperatures that vary up to ±100°F. The FLT93S Flow Switch is easily fi eld-confi gured or factory pre-set, providing unparalleled fl exibility, accuracy and stability for all multiple process sensing and switching requirements.
The rugged FLT93S Switch is hydrostatically proof pressure tested to 3500 psig [240 bar (g)] at 70°F (21°C). De-rated with temperature, the maximum operation service recommended is 2350 psig [162 bar (g)] at 500°F (260°C). Higher ratings are available with special construction and test certifi cation. Approvals available include SIL, SIL2, FM/FMc, ATEX, CSA, CRN, CE, EAC/TR CU, EQM/ECAS, IECEx and Inmetro.
Highly dependable, FCI’s versatile FLT93S Switches are ideal for applications in many demanding hazardous process industries. They also used extensively with or without SIL2 certifi cation in a wide variety of applications in the food/beverage, mining/milling, pulp/paper, pharmaceutical, water/wastewater treatment and more.
Featuring an all-welded, no-moving parts design, the FLT93S Switches require virtually no maintenance. There is nothing to break, clog or foul requiring continuous maintenance. They are available in various materials: 316L stainless steel, Hastelloy or exotic materials. In addition, these switches offer an exceptionally long life and a low lifecycle cost for superior value.
