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.

It’s no secret how President Donald Trump feels about sports teams turning away from Native American mascots. He’s repeatedly called for the return of the Washington Redskins and Cleveland Indians, claiming their recent rebrands were part of a “woke” agenda designed to erase history.

But one surprising team has really gotten the president’s attention: the Massapequa Chiefs.

The Long Island school district has refused to change its logo and name under a mandate from New York state banning schools from using team mascots appropriating Indigenous culture. Schools were given two years to rebrand, but Massapequa is the lone holdout, having missed the June 30 deadline to debut a new logo.
[url=https://kra-39--at.ru]kra33 at[/url]
The district lost an initial lawsuit it filed against the state but now has the federal government on its side. In May, Trump’s Department of Education intervened on the district’s behalf, claiming the state’s mascot ban is itself discriminatory.

Massapequa’s Chiefs logo — an American Indian wearing a yellow feathered headdress — is expected to still be prominently displayed when the fall sports season kicks off soon, putting the quiet Long Island hamlet at the center of a political firestorm.
[url=https://kra-34-at.ru]kra37 cc[/url]
The district is now a key “battleground,” said Oliver Roberts, a Massapequa alum and the lawyer representing the school board in its fresh lawsuit against New York claiming that the ban is unconstitutional and discriminatory.

The Trump administration claims New York’s mascot ban violates Title VI of the Civil Rights Act of 1964, which prohibits recipients of federal funds from engaging in discriminatory behavior based on race, color or national origin — teeing up a potentially precedent-setting fight.

The intervention on behalf of Massapequa follows a pattern for a White House that has aggressively applied civil rights protections to police “reverse discrimination” and coerced schools and universities into policy concessions by withholding federal funds.

“Our goal is to assist nationally,” Roberts said. “It’s us putting forward our time and effort to try and assist with this national movement and push back against the woke bureaucrats trying to cancel our country’s history and tradition.”

What we're covering
• Zelensky in Washington: Ukrainian President Volodymyr Zelensky has arrived in Washington, DC, where he will be joined by key European leaders when he meets with Donald Trump this afternoon. Trump says Zelensky must agree to some of Russia’s conditions — including that Ukraine cede Crimea and agree never to join NATO — for the war to end.
[url=https://kr13at.com]kra7[/url]
• Potential security guarantees: At last week’s summit with Trump, President Vladimir Putin agreed to allow security guarantees for Ukraine and made concessions on “land swaps” as part of a potential peace deal, US envoy Steve Witkoff told CNN. Zelensky suggested that such guarantees would need to be stronger than those that “didn’t work” in the past. Russia has yet to mention such agreements.
[url=https://kraken6.net]kra14 cc[/url]
• Change in tactics: Trump is now focused on securing a peace deal without pursuing a ceasefire due to his progress with Putin, Witkoff said. In seeking this deal, Trump has backed away from his threat of new sanctions on Moscow, despite calls to impose more economic pressure.

Ukrainian President Volodymyr Zelensky condemned Russian attacks on the Ukrainian regions of Kharkiv, Zaporizhzhia and Sumy on Monday, saying that the Kremlin intends to “humiliate diplomatic efforts” just hours before European leaders visit the White House.
[url=https://kra29.net]kra29[/url]
“The Russian war machine continues to destroy lives despite everything,” Zelensky said in a statement, hours before he’s due to meet US President Donald Trump in the Oval Office. “That is precisely why we are seeking assistance to put an end to the killings. That is why reliable security guarantees are required. That is why Russia should not be rewarded for its participation in this war.”
[url=https://kra25-at.cc]kra22 cc[/url]
“Everyone seeks dignified peace and true security,” the Ukrainian president said. “And at this very moment, the Russians are attacking Kharkiv, Zaporizhzhia, the Sumy region, and Odesa, destroying residential buildings and our civilian infrastructure.”

At least seven people were killed in Russia’s attack? on Kharkiv and a further three killed in the ballistic missile strike on the city of Zaporizhzhia, with scores more injured, according to Ukrainian authorities.

“This was a demonstrative and cynical Russian strike,” Zelensky added.
