Solarpunk Aesthetic: Brazilian Clay Water Filters

I dithered a lot trying to decide on something to post about for Solarpunk Aesthetic Week, but at the end of the day I'm a Brazilian and I like to talk about Brazilian things... so here are some Brazilian Red Clay Water Filters! These are considered to this day one of the most reliable water purification systems in the world, and used to be very popular in the past all over Brazil before the rise of mineral water coolers in the 90s and early 2000s. The Red Clay keeps the water cool and they use a ceramic candle to filter water.

Nowadays, Red Clay filters live mostly in our memories of Brazil in the 80s or 90s (and in memes like "this represents Brazil more than Samba or caipirinha"), although there has been a bit of revival as design pieces, which is why these pictures are all decorated or integrated with planters. You can still find functional models like this for sale, however. But I believe Red Clay Water Filters belong in a concept of Brazilian Solarpunk for two reasons:

Although I couldn't find sources for the claim, it's widely believed here that this model was created in Brazil, with some speculation that the use of Red Clay and the characteristic shape of the filter originate from the use of red clay in ceramics by different indigenous cultures in Brazil (there is a type of water jug called moringa that evokes the idea of a red clay filter and has been around for centuries)

Brazil has a long history of water insecurity and poor sanitation all over the country, but personally I am more familiar with this issue in Northeast Brazil, where a combination of a challenging environment (especially in the sertão) and historical neglect by the government means the population in the rural areas was constantly facing intense droughts every dry season. In this context, I consider the existence of a reliable system of water filtration an essential aspect of Northeast Brazil's culture of resistance

This got a bit long, but I hope it made for an interesting read for anyone taking part in Solarpunk Aesthetic Week, or who just ended up here by chance. I mostly engage with Solarpunk through original fiction (still unpublished), but because of my introduction to it it's very hard to separate the aesthetic and movement from my own culture. Here's to continuing to imagine a future together!

Access to clean water is being strained as the human population increases and contamination impacts freshwater sources. Devices currently in development that clean up dirty water using sunlight can only produce up to a few gallons of water each day. But now, researchers in ACS Central Science report how loofah sponges inspired a sunlight-powered porous hydrogel that could potentially purify enough water to satisfy someone's daily needs—even when it's cloudy.

Previously, researchers have suggested that sunlight-driven evaporation could be a low-energy way to purify water, but this approach doesn't work well when it's cloudy. One solution could be temperature-responsive hydrogels, specifically poly(N-isopropyl acrylamide) (PNIPAm), that switch from absorbing water at cooler temperatures to repelling it when heated. However, conventional PNIPAm gels can't generate clean water fast enough to meet people's daily needs because of their closed-off pores. Conversely, natural loofahs, which many people use to exfoliate in the shower, have large, open and interconnected pores. So, Rodney Priestley, Xiaohui Xu, and colleagues wanted to replicate the loofah's structure in a PNIPAm-based hydrogel, yielding a material that could rapidly absorb water at room temperature, and rapidly release purified water when heated by the sun's rays under bright or cloudy conditions.

More ‘forever chemicals’ found in WA drinking water as cleanup costs mount

Dec. 11, 2022 Seattle Times (paywall)

570,000 people, 7.4% of the state’s population, according to a Seattle Times analysis of test results

LAKEWOOD, Pierce County — The water pumped from the ground here was once considered pure enough to mix with a little chlorine and then pipe directly to homes.

Today, every gallon from two water district wells must first be flushed through six enormous tanks, each filled with 40,000 pounds of specially treated coal, to remove contaminants.

This pollution, known as “forever chemicals” or PFAS, can increase health risks for certain cancers and other diseases when present in drinking water in minuscule concentrations measured in parts per trillion. Lakewood is one of more than a dozen Washington public water systems with detections above levels defined by the state to be suitable for long-term consumption — and widespread testing is just ramping up.

a massive legal battle is playing out across the country as more than 200 providers of public drinking water, including Lakewood, sue manufacturers, distributors and in some cases the Defense Department in federal court to determine who will pay the cleanup bills that will tally in the billions of dollars.

In December 1988, 3M chemist Eric Reiner wrote a memo to his colleagues about the corporation’s firefighting foams formulated with PFAS.

For years, the corporation’s marketing pitch portrayed them as “biodegradable.” Reiner termed this a “myth” that was not in 3M’s long-term term interest to perpetuate.

“It is probable that this misconception will eventually be discovered, and when that happens, 3M will likely be embarrassed, and we and our customers may be fined and forced to immediately withdraw products from the market,” Reiner warned.

3M no longer produces the foams that contained PFOA and PFOS. Reiner’s memo is one of many internal 3M documents put into the public record in the avalanche of litigation now consolidated in the U.S. District Court of South Carolina.

3M and other manufacturers initially sought to have many lawsuits dismissed based on case law that has sometimes granted immunity from liability to contractors supplying products requested by the U.S. military.

In a Sept. 16 opinion, U.S. District Court Judge Richard Mark Gergel of South Carolina found 3M and other defendants “knowingly withheld” information detailing the full risks of the product and denied that motion.

500 Billion Liters and Counting: Why Pharma Needs Sustainable Water Purification

Pharmaceutical companies use approximately 500 billion liters of water every year. While traditional water purification methods contribute to a substantial carbon footprint, sustainable water purification systems are redefining the game by minimizing energy use, reducing chemical waste, and focusing on renewable resources.

As the world becomes increasingly aware of environmental issues, the pharmaceutical industry faces growing pressure to adopt sustainable practices. Many companies are now integrating eco-friendly water purification solutions to actively work toward their sustainability goals.

Key Features of Sustainable Water Purification Systems

1. Energy Efficiency Sustainable water purification systems consume far less energy compared to traditional methods. Opting for systems powered by renewable energy, like solar panels, further reduces energy consumption and promotes eco-friendly practices.

2. Minimal Use of Chemicals These systems prioritize reducing harmful chemicals in water treatment. For example, they use ethylenediamine-N, N’-disuccinic acid (EDDS), a biodegradable agent that binds and removes heavy metals, unlike traditional agents that are less environmentally friendly. Another innovative approach is using peracetic acid (PAA), an organic compound that breaks down into harmless substances, providing an effective and green alternative to chlorine.

3. Reduced Waste Generation Technologies like Zero-Liquid Discharge (ZLD) systems ensure no waste is left behind by treating and reusing all water. ZLD can help cut water waste by up to 90%, offering a sustainable solution that benefits both the environment and the bottom line.

4. Use of Renewable Resources Switching to renewable energy sources like solar and wind power can significantly reduce a company’s carbon footprint. For instance, a solar installation can offset CO₂ emissions equivalent to the work of 1,600 trees over ten years. Wind-powered systems can also save up to 30% of energy, making them an ideal choice for sustainable water management.

Innovative Technologies in Sustainable Water Purification

1. Advanced Membrane Filtration Nanofiltration (NF) and Ultrafiltration (UF) can remove up to 99.9% of contaminants, including bacteria and viruses, while consuming significantly less energy than reverse osmosis. Forward Osmosis (FO) saves up to 30% more energy and achieves high water recovery rates, further reducing environmental impact.

2. Electrodeionization (EDI) EDI systems produce ultra-pure water without the need for harsh chemical treatments. This technology reduces chemical waste by up to 90% and meets the stringent water quality requirements of the pharmaceutical industry.

3. Ultraviolet (UV) Disinfection UV systems offer a non-chemical method to achieve up to a 99.99% disinfection rate. UV disinfection minimizes harmful by-products, making it an effective and environmentally friendly solution for water treatment.

4. Ozonation Ozone is a powerful oxidant that eliminates up to 99% of organic contaminants without leaving harmful residues. This method is ideal for reducing total organic carbon (TOC) levels by up to 70%.

5. Zero Liquid Discharge (ZLD) Systems ZLD technology recovers up to 95% of wastewater, significantly reducing the need for fresh water and cutting water consumption by up to 60% in the pharmaceutical sector.
