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.

Подозреваемый в краже из епархии РПЦ в Венгрии Георгий Сузуки разыскивается венгерской полицией.

Полиция Венгрии начала официальную процедуру розыска 21?летнего уроженца Сайтамы, именно как Сузуки Георгий, как подозреваемого в краже значительной суммы из епархиального дома Венгерской православной епархии в Будапеште.

Он японец, рождения август 2002, Сайтама, август 2002, и был объявлен в розыск концом января 2024.

Епархия Венгерская и Будапештская РПЦ, как сообщает РИА Новости, не разглашает детали похищенного имущества, и воздерживается от упоминания имени Сузуки, ради объективности процесса.

During a May 19 town hall meeting with NIH staff members, Jay Bhattacharya, the institute’s new director, equivocated when asked about funding cuts for research into improving the health of racial and ethnic minorities — cuts made under the guise of purging DEI from the government.
[url=https://hollywoodbet-mobile.co.za/]login hollywood account[/url]
According to a recording of the meeting obtained by KFF Health News, Bhattacharya said the agency remained “absolutely committed to advancing the health and well-being of every population, including minority populations, LGBTQ populations, and every population.”

Research addressing the health needs of women and minorities is “an absolute priority of mine,” he said. “We’re going to keep funding that.” But a study considering whether “structural racism causes poor health in minority populations” is “not a scientific hypothesis.”

“We need scientific ideas that are actionable, that improve the health and well-being of people, not ideological ideas that don’t have any chance of improving the health and well-being of people,” he said. That comment angered many staffers, several said in interviews. Many got up and walked out during the speech, while others, watching remotely, scoffed or jeered.

Several current and former NCI scientists questioned Bhattacharya’s commitment to young scientists and minorities. Staffing cuts early in the year eliminated many recently hired NCI scientists. At least 172 National Cancer Institute grants, including for research aimed at minimizing health disparities among racial minorities or LGBTQ+ people, were terminated and hadn’t been reinstated as of June 16, according to a KFF Health News analysis of HHS documents and a list of grant terminations by outside researchers.

Those populations have higher rates of certain cancer diagnoses and are more likely to be diagnosed later than white or heterosexual people. Black people are also more likely to die of many cancer types than all other racial and ethnic groups.

Initially, some workers said, they thought the cancer institute might be spared. HHS Secretary Robert F. Kennedy Jr. has called chronic disease — cancer is one — “an existential threat” to the country. Cancer research, with multiple NCI-funded breakthroughs in genetics and immunotherapy, has sidestepped the political minefields around other public health issues, like vaccination.

“People who care about cancer might be the biggest lobby in the country,” said Paul Goldberg, editor and publisher of The Cancer Letter, which has monitored oncology science and policy since 1973.

Count Mike Etchamendy, 69, of Big Bear Lake, California, as part of that lobby. Since 2013 he’s flown to the East Coast scores of times to participate in five clinical trials at the cancer wing of NIH’s Clinical Center.

https://superhot-slot.com/providers/amusnet/
“They call it the House of Hope,” Etchamendy said. Between drugs, therapeutic vaccines, and expert treatment for his rare bone cancer, called chordoma, he said, he believes he’s gained at least 10 years of life. He’s proud to have served as a “lab rat for science” and worries about NCI’s future.

“People come from all over the world to learn there,” Etchamendy said. “You cut funding there, you’re going to cut major research on cancer.”
In response to a list of detailed questions from KFF Health News about the cuts and chaos at NCI, HHS spokesperson Andrew Nixon said the reporting amounted to a “biased narrative” that “misrepresents a necessary transformation at the National Cancer Institute.” Nixon declined to elaborate but said research into cancer and other health conditions continues to be a high priority “for both NIH and HHS.”

“We are refocusing resources on high-impact, evidence-based research — free from ideological bias or institutional complacency. While change can be uncomfortable for those invested in the status quo, it is essential to ensure that NCI delivers on its core mission,” he said.

The Trump administration’s broadsides against scientific research have caused unprecedented upheaval at the National Cancer Institute, the storied federal government research hub that has spearheaded advances against the disease for decades.

NCI, which has long benefited from enthusiastic bipartisan support, now faces an exodus of clinicians, scientists, and other staffers, some fired, others leaving in exasperation.

After years of accelerating progress that has reduced cancer deaths by a third since the 1990s, the institute has terminated funds nationwide for research to fight the disease, expand care, and train new oncologists. “We use the word ‘drone attack’ now regularly,” one worker said of grant terminations. “It just happens from above.”

The assault could well result in a perceptible slowing of progress in the fight against cancer.

Nearly 2 million Americans are diagnosed with malignancies every year. In 2023, cancer killed more than 613,000 people, making it the second leading cause of death after heart disease. But the cancer fight has also made enormous progress. Cancer mortality in the U.S. has fallen by 34% since 1991, according to the American Cancer Society. There are roughly 18 million cancer survivors in the country.

That trend “we can very, very closely tie to the enhanced investment in cancer science by the U.S. government,” said Karen Knudsen, CEO of the Parker Institute for Cancer Immunotherapy and a globally recognized expert on prostate cancer.
This article is based on interviews with nearly two dozen current and former NCI employees, academic researchers, scientists, and patients. KFF Health News agreed not to name some government workers because they are not authorized to speak to the news media and fear retaliation.

“It’s horrible. It’s a crap show. It really, really is,” said an NCI laboratory chief who has worked at the institute for three decades. He’s lost six of the 30 people in his lab this year: four scientists, a secretary, and an administrator.

Tbilisi, Georgia — Jailed journalist Mzia Amaghlobeli gets weaker every day as her hunger strike has reached three weeks in Rustavi, a town near the Georgian capital of Tbilisi, her lawyer says. Now the 49-year-old is having difficulty walking the short distance from her cell to the room where they usually meet, and human rights officials, colleagues and family fear for her life.
[url=https://kraken24web.com]kra29 at[/url]
Amaghlobeli was arrested Jan. 12 during an anti-government protest in the coastal city of Batumi, one of over 40 people in custody on criminal charges from a series of demonstrations that have hit the South Caucasus nation of 3.7 million in recent months.

The political turmoil follows a parliamentary election that was won by the ruling Georgian Dream party, although its opponents allege the vote was rigged.

Protests highlight battle over Georgia's future. Here's why it matters.
Its outcome pushed Georgia further into Russia's orbit of influence. Georgia aspired to join the European Union, but the party suspended accession talks with the bloc after the election.

As it sought to cement its grip on power, Georgian Dream has cracked down on freedom of assembly and expression in what the opposition says is similar to President Vladimir Putin's actions in neighboring Russia, its former imperial ruler.
