Hudson, Mass., Installs Filtration Systems to Address Elevated Levels of PFAS In Water Supply

PFAS Water Contamination

The town of Hudson, Massachusetts, installed two temporary filtration systems to address heightened levels of perfluoroalkyls (PFAS) in its water supply, according to a report by the MetroWest Daily News. The systems were installed at Hudson’s Cranberry well and Chestnut Water Treatment Plant, and the level of PFAS was undetectable at each site as of last week.

A water sample taken in January at the Hudson treatment plant was found to have 76 parts per trillion, above the state Department of Environmental Protection’s safe standard of 70 parts per trillion. Prior to the installation of the new filtration systems, the issue was resolved by shutting down the Cranberry well, which brought the PFAS level under the 70 parts per trillion threshold.

Boyd Coatings, the former operator of a coatings production facility in Hudson, along with Precision Coating, which purchased Boyd in 2016; and Dylan LP, the owner of the property where the business is located, are being investigated to determine if they are responsible for the elevated level of PFAS in the water supply.

MetroWest Daily News reported that Boyd Coatings is named in a lawsuit filed by the town, and Hudson officials are working with the parties to reach a solution. The filtration systems cost the town an estimated $1 million.

Zero Liquid Discharge Market Projected to Reach US $9B by 2025

ZLD Market Size Through 2025

Zero liquid discharge (ZLD) system market size is being driven by the declining level of freshwater sources globally, according to a new report by Global Market Insights. The level of wastewater from industry is rising at an alarming rate, and this water must be treated and recycled for continuous industrial usage. The rise of industrialization in developing economies such as India, China, Thailand, etc. are growing unceasingly, which is also diminishing the supply of fresh water worldwide. Moreover, Global Market Insights says the ever-growing population is also an integral factor that is positively fueling the ZLD system market size in the near future.

Severe protocols created by the regional government bodies are compelling manufacturing organizations to set up ZLD units in their plants. These systems purify the wastewater and also recycle for further use in the manufacturing operations. The use of ZLD units in the production plants would help in keeping the ecosystem safe with a reduction in water borne diseases. Several government organizations are imposing strict guidelines concerning the disposal of wastewater, which would directly propel the demand for zero liquid discharge (ZLD) system market in the coming years.

Set-up cost and operating expenses may prove to be a hindrance in the growth of the zero liquid discharge system market in the near term. In addition, ZLD units require a lot of space and skilled personnel to function, which can be a challenge for the smaller business. However, stiff guidelines will mandate the use of ZLD in various industries, directly fueling the product industry size in the near future.

The ZLD system market size based on its products are segmented into conventional and hybrid units. Hybrid units are projected to grow at considerable rate to exceed US $4.2 billion at the end of the expected timeframe. Hybrid units consist of pretreatment sections with brine purification, MVR evaporator, crystallizer and a solid separation unit, which helps recycling the wastewater continuously.

Thermal-based systems segment will exhibit a surge in its growth with a CAGR over 5.5 percent during the forecast period. Thermal based ZLD systems are mostly used with conventional units, since it helps in recovering more than 95 percent of the plant’s wastewater, while decreasing the remaining affluents as end products. 

Energy and power end-use sectors will capture over 25 percent of the entire segment share in the coming year. Zero liquid discharge is quite imperative for the steam electric power industries, since the coal powered plants possesses a huge water consumption and challenging water disposal, this will positively influence the ZLD system market size by 2025. 

Europe registered a revenue over US $1.5 billion in 2018 and is expected to dominate the product market size in the future. Many European countries are industrially strong and face water scarcity, which compels the use of zero liquid discharge system.

The prominent players in ZLD system market includes Aquatech International, Veolia, GEA Group, ALFA LAVAL, Suez Water Processes, H2O, Oasys Water, Aquarion, Praj Industries, ENCON, Kelvin Water, IDE Technologies, Austro Chemicals, and SafBon.

Four Ways China Is Fighting Air Pollution

A new Freedonia study finds that the Chinese market for internal combustion engine, air, and fluid filters will approach $18 billion in 2022, and remain the largest in the world. Among the factors driving market growth, efforts by regulators to curb the nation’s notorious air pollution problem, such as by raising filtration standards, will continue to have an impact. For example, as China neared its 2020 air-quality targets ahead of schedule, the government introduced stricter goals.

Here are four ways China is shedding its reputation as the smog capital of the world:

1. Imposing more demanding vehicle and factory emissions standards: While less restrictive than those in the US or the EU, Chinese emissions limits have decreased in recent years, creating need for higher-performing filters and significantly improving air quality.

2. Shuttering tens of thousands of polluting factories, and cracking down on both lax and excessive enforcement by local authorities via a national inspection system: An unintended result of a “one size fits all” approach to environmental standards in China has been an effective blanket-ban of heavy industry, but now local governments are allowed to set their own targets.

3. Investing in green energy and advanced filtration technologies: China leads the world in renewable energy investment, and as concerns about pollution continue to grow in China, consumers will increase their use of air and fluid filtration products.

4. Partnering with other governments and organizations to address key goals: For example, ongoing collaboration between China’s Ministry of Ecology and Environment and the US Environmental Protection Agency has yielded stronger methods for assessing and mitigating pollution levels.

But China is not the only country making strides in this arena. Freedonia’s Global Filters study examines trends in all major national filter markets to provide historical demand by major product group and end-use market, as well as sales forecasts for 2022 and 2027.
