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.

Cracker Barrel’s modern makeover doesn’t stop with redoing its restaurants. It’s dropping the barrel and the man from its logo, too.

On Tuesday, the Southern-inspired casual dining chain unveiled a new logo “rooted even more closely to the iconic barrel shape,” but without the barrel itself — a central part of the brand’s identity since 1977. (As for the the barrel itself, it was “essentially the water coolers of the day,” Cracker Barrel explained in a blog post.)
[url=https://tripskan39.cc]tripscan[/url]
The identity refresh also includes new TV commercials, a redesigned menu and several new fall-themed foods, part of a larger $700 million transformation plan to shake off its stodgy image and lure in new diners.

“The way we communicate, the things on the menu, the way the stores look and feel … all of these things came up time and time again in our research as opportunities for us to really regain relevancy,” said CEO Julie Felss Masino in 2024.

In particular, the new logo is the latest in a string of changes angering some of its loyal fans who fear the 56-year-old chain is drifting too far from its bucolic roots. On social media, some users griped, with one writing that the “changing the logo just feels like another little piece of culture dying off.” The change also angered some conservatives, too, like President Donald Trump’s son.

Cracker Barrel has also been remodeling some of its 660-plus restaurants. The chain has “decluttered” the interiors by removing the country-themed trinkets that lined the walls and lightened up the interiors, shifting away from the dark woods. So far, reaction has been mixed on social media, with some videos on TikTok going viral voicing their displeasure.

Masino remains adamant that the renovations are working, telling ABC News this week that “people like what we’re doing” and that feedback has been “overwhelmingly positive.”

In June, Cracker Barrel posted an unusual earnings report for a restaurant: It’s taking a $5 million hit from tariffs because of its retail shops, which largely has products imported from overseas. Restaurant revenue and same-store sales both slightly grew, mirroring other increases casual dining chains are experiencing.

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.

“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://kra27cc.net]kra23 at[/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.

For people who cannot or choose not to breastfeed, infant formula is lifesaving, supplying their babies with precious nutrients they need to grow and thrive.

Concerned about contaminants and the use of controversial seed oils in the nation’s tightly regulated infant formula supply, US Health and Human Services Secretary Robert F. Kennedy Jr. has launched a review of infant formula regulations he calls Operation Stork Speed.
[url=https://trip-scan39.cc]tripscan[/url]
Yet while industry and experts debate those regulations, there is another type of “formula” — for toddlers ages 1 to 3 years old — that no one is overseeing.

“Toddler milks” are marketed to parents who have been using infant formula as a necessary next step in their child’s nutritional journey, according to the American Academy of Pediatrics. Critics say these expensive concoctions — first introduced into the United States in the 1990s — are not nutritionally necessary, may be contributing to childhood obesity, and should not be sold at all.

In fact, some toddler beverages may be potentially harmful to young children due to excess added sugars, defined as sweeteners that don’t naturally occur in food, Fuchs said.

The recommended amount of added sugar for infants and children younger than age 2 is zero, according to the US Centers for Disease Control and Prevention. Yet research from 2019 found that on average, infants consume 1 teaspoon of added sugar a day while toddlers consume about 6 teaspoons a day.

“Infants and children exposed to high sugar, fat or salt in their diets develop a preference for these as they grow older,” Fuchs said. “Studies show this is a risk for childhood obesity and all of its consequences through adulthood.”
