Aquapolo Ambiental Water Reuse Project

Overview

Aquapolo Ambiental is a water reuse venture created by Foz do Brasil (Odebrecht Organization) and Sabesp, a Brazilian state-owned utility that provides water and sewage services for residential, commercial, and industrial use in the municipalities of the state of São Paulo. The Aquapolo project was initiated to address new government regulations to restrict industrial use of potable water in São Paulo and is the largest industrial water reuse project in the Southern Hemisphere. Aquapolo will supply the Capuava Petrochemical Complex of Mauá, located in São Paulo’s ABC region, thereby conserving enough drinking water to continuously supply a population of 300,000 people.

The Challenge

To build a treatment plant capable of meeting São Paulo’s pressing demand for industrial reuse water.

The Solution

Koch Membrane Systems, Inc. (KMS), a leading supplier of wastewater treatment systems, provided PURON® membrane bioreactor (MBR) modules as well as MegaMagnum® reverse osmosis (RO) membranes, system design and controls, and after-market support and service for the Aquapolo project. KMS was chosen for its superior technical support and biological design, the availability of MBR and RO pilot plants, its vast experience with water-recycling projects, and ability to meet an extremely accelerated delivery schedule.

KMS conducted a comprehensive feasibility study to identify the most cost-effective strategy to upgrade the existing plant infrastructure and concluded that membrane bioreactor (MBR) technology with a Tertiary Membrane Bioreactor (TMBR) system was the best solution for the new facility.

“Koch Membrane Systems’ willingness to work with us as our technological partner was a key factor in our decision to award them the contract,” said Emyr Diniz Costa, Senior Project Director at Odebrecht. “They offered a comprehensive engineering solution and dedicated extensive pre-engineering man-hours to produce the most reliable design and the state-of-the art technology for our project. The availability of a pilot plant convinced us their solution was the best one.”

 

The Treatment Plant

In total, the Aquapolo project encompasses the construction of new a pretreatment step, installation of a chemical dosing system, and the construction of a 700 lps TMBR utilizing 94,500 m2 of membrane area. The TMBR offers lower operating costs, lower process risk, greenfield design, and negligible interaction with current plant operations and equipment.

The TMBR is a polishing MBR process. It will treat water coming from the existing secondary clarifiers and further treat it in a newly built biological step using membranes as the final separation process. Some of the TMBR effluent will be further treated by RO membranes to meet conductivity goals for water reuse.

The TMBR pilot demonstrated that the submerged membranes benefited from the optimized biological system. Average flux rates of >25 L/m2h were achieved and daily maintenance cleaning was found to enhance the UF performance. Recovery cleaning returned the UF membrane to the original process permeability. A standard RO pilot also was used to simulate the RO design concept of the proposed full scale system for 200 L/s feed water. The pilot trials were setup in three well-defined phases, a simple batch mode, a modified batch mode and a continuous mode. The RO system was able to produce an excellent water quality.

Elusive shipwreck found in Lake Michigan over 100 years after sinking
[url=https://rutorclubwiypaf63caqzlqwtcxqu5w6req6h7bjnvdlm4m7tddiwoyd.com]rutor сайт[/url]
A “ghost ship” that sank in Lake Michigan nearly 140 years ago and eluded several search efforts over the past five decades has been found, according to researchers with the Wisconsin Underwater Archeology Association.

The wooden schooner got caught in a storm in the dead of night and went down in September 1886. In the weeks after, a lighthouse keeper reported the ship’s masts breaking the lake surface, and fishermen caught pieces of the vessel in their nets. Still, wreck hunters were unable to track down the ship’s location — until now.

Earlier this year, a team of researchers with the Wisconsin Underwater Archeology Association and Wisconsin Historical Society located the shipwreck off the coastal town of Baileys Harbor, Wisconsin, the association announced on Sunday.

Named the F.J. King, the ship had become a legend within the Wisconsin wreck hunter community for its elusive nature, said maritime historian Brendon Baillod, principal investigator and project lead of the discovery.

“We really wanted to solve this mystery, and we didn’t expect to,” Baillod told CNN. “(The ship) seemed to have just vanished into thin air. … I actually couldn’t believe we found it.”

The wreck is just one of many that have been found in the Great Lakes in recent years, and there are still hundreds left to be recovered in Lake Michigan alone, according to Baillod.

The ‘ghost ship’
Built in 1867, the F.J. King plied the waters of the Great Lakes for the purpose of trans-lake commerce. The ship transported grains during a time when Wisconsin served as the breadbasket of the United States. The 144-foot-long (44-meter) vessel also carried cargo including iron ore, lumber and more.

The ship had a lucrative 19-year career until that September night when a gale-force wind caused its seams to break apart, according to the announcement. The captain, William Griffin, ordered the crew to evacuate on the ship’s yawl boat, from where they watched the F.J. King sink, bow first.

Denmark’s foreign minister on Monday said he was “deeply upset” by US President Donald Trump’s appointment of a special envoy to Greenland who openly declared that he wished to see the island become part of the United States.

Trump announced the appointment of Jeff Landry, the Governor of Louisiana, as ?special envoy to Greenland on Monday in a post on Truth Social. “Jeff understands how essential Greenland is to our national security, and will strongly advance our country’s interests for the safety, security, and survival of our allies, and indeed, the World,” Trump posted on his social media platform.

“I am deeply upset by this appointment of a special envoy. And I ?am particularly upset by his statements, which we find completely unacceptable,” Lars Lokke Rasmussen told Denmark’s national broadcaster TV 2, according to Reuters news agency.

Rasmussen said he would summon the US ambassador to Denmark in response to the Trump administration’s move, Reuters reported.

Trump defended his decision to pick Landry telling reporters on Monday evening that the US needs Greenland “for national security” and that Landry had approached him about the assignment.

“Louisiana, the Louisiana Purchase. He said I’m governor of Louisiana, and he said I would love … I didn’t call him, he called me. He’s very proactive,” Trump told reporters at Mar-a-Lago.

“We need Greenland for national security, not for minerals. We have so many sites for minerals and oil and everything,” Trump said, trying to make the case for annexing Greenland, despite its status as a self-governing territory of Denmark. “If you take a look at Greenland, you look up and down the coast, you have Russian and Chinese ships all over the place. We need it for national security. We have to have it,” he added.

During his Monday remarks, Trump went on to claim that Denmark has “spent no money” on Greenland and has “no military protection.”

While thanking Trump for his appointment, Landry said it was an “honor to serve you in this volunteer position to make Greenland a part of the US.” He also said that “this in no way affects” his position as Louisiana governor.

Trump has repeatedly stated that he wants to annex Greenland – a huge, resource-rich island in the Atlantic and self-governing territory of Denmark – claiming that this is needed for American security purposes.

Both Greenland and Denmark, a NATO ally of the US, are staunchly opposed to the idea.

Danish Prime Minister Mette Frederiksen and Greenland’s Prime Minister Jens-Frederik Nielsen reiterated their opposition Monday to US plans to take over Greenland, stating “you cannot annex another country. Not even with an argument about international security,” according to Reuters.

“Greenland belongs to the Greenlanders and the US shall not take over Greenland,” they said in a joint statement.

Nielsen said earlier Monday that Trump’s announcement “may sound big, but it does not change anything for us. We decide our own future,” Reuters reported.

CBS News editor in chief Bari Weiss decided to shelve a planned “60 Minutes” story titled “Inside CECOT,” creating an uproar inside CBS, but the report has reached a worldwide audience anyway.
[url=https://minexchange.net]mine шахта[/url]
On Monday, some Canadian viewers noticed that the pre-planned “60 Minutes” episode was published on a streaming platform owned by Global TV, the network that has the rights to “60 Minutes” in Canada.
[url=https://minexchange.net]mine exchange[/url]
The preplanned episode led with correspondent Sharyn Alfonsi’s story — the one that Weiss stopped from airing in the US because she said it was “not ready.”
[url=https://minexchange.net]mine шахта[/url]
Several Canadian viewers shared clips and summaries of the story on social media, and within hours, the videos went viral on platforms like Reddit and Bluesky.

“Watch fast,” one of the Canadian viewers wrote on Bluesky, predicting that CBS would try to have the videos taken offline.

Inside the Bari Weiss decision that led to a ‘60 Minutes’ crisis

Progressive Substack writers and commentators blasted out the clips and urged people to share them. “This could wind up being the most-watched newsmagazine segment in television history,” the high-profile Trump antagonist George Conway commented on X.

A CBS News spokesperson had no immediate comment on the astonishing turn of events.

Alfonsi’s report was weeks in the making. Weiss screened it for the first time last Thursday night. The story was finalized on Friday, according to CBS sources, and was announced in a press release that same day.

On Saturday morning, Weiss began to change her mind about the story and raised concerns about its content, including the lack of responses from the relevant Trump administration officials.

But networks like CBS sometimes deliver taped programming to affiliates like Global TV ahead of time. That appears to be what happened in this case: The Friday version of the “60 Minutes” episode is what streamed to Canadian viewers.

The inadvertent Canadian stream is “the best thing that could have happened,” a CBS source told CNN on Monday evening, arguing that the Alfonsi piece is “excellent” and should have been televised as intended.

People close to Weiss have argued that the piece was imbalanced, however, because it did not include interviews with Trump officials.

Weiss told staffers on Monday, “We need to be able to get the principals on the record and on camera.” However, in an earlier memo to colleagues, Alfonsi asserted that her team tried, and their “refusal to be interviewed” was “a tactical maneuver designed to kill the story.”

At the end of the segment that streamed on Global TV’s platform, Alfonsi said Homeland Security “declined our request for an interview and referred all questions about CECOT to El Salvador. The government there did not respond to our request.”

The segment included sound bites from President Trump and Homeland Security Secretary Kristi Noem. But it was clearly meant to be a story about Venezuelan men deported to El Salvador, not about the officials who implemented Trump’s mass deportation policy.
