Designed by Wärtsilä Water and Waste’s partner FilterSafe, the Manta filter features a OneMotion scanner that cleans the screen in just a single rotation. Tests have shown that the Manta filter is capable of fast and efficient screen cleaning, even with heavy dirt loads.
At the DHI test facilities in Denmark, organic load tests showed that the Manta filter exceeded IMO standards by a factor of 22 without any reduction in the flow rate. The DHI measurements also indicated the removal efficiency to be 99.96% of all organisms over 50 microns. The Manta is also type approved by Bureau Veritas Group (Marine).
“This takes BWMS filtration to the next level and will be an important addition to the Aquarius UV system. The impressive test results validate the effectiveness of the Manta filter, which will add considerable value to our customers’ operations,” said Leif Abildgaard, sales director at Wärtsilä Water and Waste.
To meet the needs of UV secondary treatment, the Wärtsilä Aquarius UV system utilises a Manta filter with a 25 micron smartweave screen. The non-pleated screen prevents sediment from becoming trapped, and there is no cake build-up across the screen. Each cleaning cycle brings the screen back to 100% cleanliness.
The Wärtsilä Aquarius UV BWMS is the first system to be fitted with the Manta filter. Class and IMO equivalency testing is currently being finalised. The US Coast Guard also allows the Manta filter to be used in BWMS installations that they have already authorised.
