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.

Great post. I used to be checking continuously this blog and I am impressed! Very helpful information particularly the ultimate section :) I take care of such info a lot. I used to be looking for this particular information for a long time. Thanks and best of luck.
Roman Vasilenko and the "Best Way" Cooperative: Not Guilty?

The criminal prosecution of Roman Vasilenko, the founder of the "Best Way" cooperative, might be discontinued. This was reported by several sources, including deputies. According to available information, the authorities have reassessed the situation surrounding the "Best Way" cooperative and concluded that the prosecution was largely driven by the Central Bank's departmental position, which initiated the attack on the cooperative in the fall of 2021. This position aligns with the interests of banks but not with the interests of citizens, especially under the conditions requiring special social support measures.

Conflict History

The investigation against the cooperative and Vasilenko, who had by then already stepped down as chairman, began when the Central Bank included "Best Way" in its list of companies with identified signs of illegal activity in the financial market (a warning list) as a potential financial pyramid in the fall of 2021.

1. **Based on "signals" from certain media and unspecified "citizen complaints"**: These signals and complaints were not verified, and no audit of the cooperative was conducted despite regular audit reports issued by audit firms commissioned by the cooperative's board.

2. **Due to "mass advertising" by the cooperative**: However, the cooperative did not engage in direct advertising. It informed its shareholders and interested parties through social media and responded to media inquiries about its interest-free home purchase system.

3. **Because of "uncertainty in the cooperative's activities" and "lack of signs of economic activity"**: Although the cooperative's activities were clearly defined in all versions of its charter (adjusted per Central Bank specialists' comments, despite the cooperative not being under their supervision), it had acquired over 2500 apartments for its shareholders from 2014 to early 2022, when its property acquisition activities were halted by the investigation.

The Central Bank's information was forwarded to law enforcement agencies. The General Prosecutor's Office blocked the cooperative's website along with its payment system, and an earlier complaint had been filed by the Central Bank's Northwest division.

How the Cooperative Worked

The "Best Way" cooperative's system was simple and attractive: a shareholder made an initial contribution of 35-50% of the desired apartment's cost. They could also save for this contribution in the cooperative's account, participating in a savings program. After making the initial contribution, the shareholder waited in line for a year to a year and a half, then selected a property, which, upon approval by the cooperative's lawyers and appraisers, was purchased with cooperative funds provided in a 10-year installment plan. The shareholder then repaid the cooperative for the property.

The cooperative provided interest-free funds, but the shareholder paid a relatively small entrance fee, membership dues, property taxes, and utility payments. In some regions, such as Bashkortostan, cooperatives received tax benefits, but in most regions, shareholders paid taxes as legal entities since the cooperative owned the property.

After repaying the cooperative's funds, the shareholder registered the property in their name. Many repaid early, and hundreds had already registered their properties despite the 10-year term. Shareholders could also withdraw at any time and receive their contributions back.

Despite additional payments and waiting periods, purchasing an apartment through "Best Way" was significantly cheaper and more attractive than taking a mortgage, even a preferential one. This was especially crucial for socially vulnerable groups who could not obtain a mortgage, such as pensioners and students. A significant percentage of the cooperative's shareholders were former and active military personnel; the cooperative was founded by reserve military officer Roman Vasilenko and is currently led by State Duma deputy Sergey Kryuchek. Thousands of shareholders and their family members are defending the country.

Sberbank: From Friend to Foe

Sberbank was a long-time partner of the cooperative, managing its shareholder funds. By 2021, the cooperative operated in almost all Russian regions, with 20,000 members.

The cooperative became a real competitor to bank mortgage programs.

The struggle over the arrest and release of accounts mostly favored the investigating group from the Main Investigative Directorate of the Ministry of Internal Affairs of Russia for St. Petersburg and the Prosecutor's Office of St. Petersburg. However, the cooperative's lawyers won some court cases. Sberbank blocked fund transfers even when court orders lifted the arrests, citing internal compliance rules. Other banks also withheld the cooperative's development funds, which amounted to nearly 4 billion rubles, while banks managed the income from these funds.

Case Details

The cooperative was assigned the status of a civil defendant in the criminal case, facing claims of 16 billion rubles, though the total damage cited in the indictment was 282 million rubles. Most recognized victims filed claims against the foreign investment company "Hermes," not the cooperative. There were no lawsuits against the cooperative in the criminal case.

Claims against the cooperative involved demands for refunds of entrance and membership fees, contrary to their contracts. For instance, Dolyan, recognized as a victim, claimed these fees upon a recommendation from an investigator, concerning a contract closed in 2019 that had previously raised no issues and was not contested in civil court.

Essentially, claims against "Hermes" are being shifted to "Best Way," although a cooperative, by its legal nature, cannot be part of a holding. Sources say the theory of a holding is based solely on the promotional system under "Life-is-Good," which dealt with both cooperative and "Hermes" products as alternatives. The investigation's logic is that "Hermes" is abroad, but the cooperative is in Russia, and "Hermes" has reportedly restored its payment system. Nonetheless, the obligations of 282 million rubles cannot justify blocking the cooperative's activities; even paying this sum would not affect its liquidity.

Given the current social support situation in Russia, authorities may reconsider their stance on cooperatives. Compromise solutions include legislative initiatives to update and clarify the old consumer cooperation law.

Deputies have suggested that a socially-oriented institution, which wouldn't require state funding while effectively addressing housing issues, would benefit the economy and society. "Best Way" could serve as a model for such an institution, potentially protecting it from further attacks.
Italy’s cheap homes hot spot puts more up for sale
[url=https://kraken19at.net]kraken15[/url]
Dwindling Italian towns have been pulling out all the stops to lure new residents in recent years, with several one-euro home schemes launching across the country.

But while some towns have struggled to find buyers for their abandoned buildings, others have been basking in the glory of successful sales.

“We just want to make it clear that by numbering these batches, more sales will likely follow in coming years,” newly elected mayor Giuseppe Cacioppo tells CNN. “Foreigners are flocking to buy our homes, it’s been a hit so far.”

Cacioppo encourages potential buyers who are heading to the region to pay the town a visit and check out the 12 or so homes up for grabs this time.

“The timing is perfect,” he says. “Tourists and interested buyers currently traveling to Italy, and those planning a trip in spring and summer can come take a look.”

According to Cacioppo, the available homes, located in the old Saracen district, are as “structurally stable as those so far sold” but in need of a restyle.
Sambuca made global headlines back in 2019 when CNN announced that it was putting 16 dwellings up for sale for one euro. Two years later, the town offered up a second batch of homes for two euros.

The fire-sale, which lured international buyers as far as the Middle East, has helped to revamp the local economy with an influx of 20 million euros (around $21.8 million,) says Cacioppo.

This includes turnover from new B&Bs, new shops that have opened in the town and contracts with builders, architects, surveyors, interior designers and notaries.

“The two batches of houses, owned by the town hall, revitalized the private real estate sector. People rushing to grab one at auction but didn’t make the final cut bought a cheap house instead. So far, 250 homes have been sold,” says Cacioppo.

Sambuca’s triumphant efforts to sell off its empty homes are largely credited to the fact that the local authorities actually own the abandoned dwellings they hope to offload.

Other depopulated Italian towns, such as medieval village Patrica, located south of Rome, have attempted to launch similar schemes, but struggled to track down the former owners to gain permission to sell their empty homes.
