Prime Lake Technology Sweden AB (Prime Lake) on Thursday (9 July) said it has successfully completed a pilot test for the elimination of harmful contaminants found in wastewater generated from open loop scrubbers.
The test results, obtained by ALS Scandinavia, verify a significant reduction of Polycyclic Aromatic Hydrocarbons (PAHs) and Sulphur (S), improved turbidity and pH-levels, as well as a dramatic increase of dissolved oxygen (DO).
Prime Lake added it is now moving ahead with its partner, one of Europe’s largest ship owners, to assess and optimize the onboard technical implementation for seaborne trials.
“Coinciding with the new IMO 2020 framework we early on identified treatment of wastewater from scrubbers as a priority, with so-called open loop scrubbers being especially problematic from a marine pollution perspective as they discharge wastewater straight into the ocean,” said Victor Chang, CEO, Prime Lake.
“Although further tests are required for optimization it is safe to say that our Electro-Aeration solution transforms the wastewater from open loop scrubbers into a ‘product’ that can be discharged with minimal impact on the marine environment, falling well within acceptable limits.”
“As a response to the IMO 2020 framework owners globally rushed to install scrubbers in order to be compliant with the sulphur cap, with an estimated 85% of owners opting for open loop scrubbers,” added George Kinigalakis, Chief Compliance Officer at Prime Lake and former expert advisor on EU programs around ship recycling.
“However, wastewater generated from scrubbers caused several key ports to enact ECAs, which over time would create a challenging environment – for liners in particular – to operate key routes.
“Consequently, it is satisfying that we are now able to present a possible solution for these owners, and we are looking forward to seaborne trials to advance this technology further.”

MHI Group successfully completed the installations as scheduled through remote commissioning conducted with engineers of its local partners in China and Singapore.
Scrubbers need accurate data to ensure they are making an informed decision on the effectiveness and longevity of their equipment, says Chelsea Technologies.
‘This is expected to delay the payment of between USD 20.0 million and USD 25.0 million of expenditures until 2021 at the earliest,’ reads company report.
Two ultra-large container ships with scrubbers installed continued use of existing fuel oil while meeting all SOx emission regulations.
To encourage ships to deposit their liquid waste and scrubber residues on site, the Port said it would absorb 30% of the costs involved in waste collection.

‘We intend to expand our product portfolio to include VLSFO bunker deliveries at a later stage; after investments into the MGO bunkering segment have been complete,’ Director tells Manifold Times.
Fast Energy Sdn Bhd is currently exploring collaboration with a major Malaysian bunker supply firm operating at Port Klang; the operation will be supported by CCK Petroleum upon finalisation.
Veritas Petroleum Services records numerous contaminants such as plastic, fibres, black gum, paraffins, fatty acids, and other component found in the off-spec RMK 700 marine fuel.
Course includes topics on valid and binding transactions; quality or quantity disputes; shipping issues; contract termination; claims; insolvency and others. Registration closes 25 February 2021.
All bunker vessels that have received the necessary clearance for out of port bunkering operations may do so at the stated Tompok Utara coordinates only or risk penalty, according to the MMEA.
The COVID-19 pandemic continues to evolve and MPA is working closely with other agencies to monitor the situation, both globally and in Singapore, the port authority tells Manifold Times.
