Membrane filtration is among the newer strategies for tackling tiny pollutants Concerns about microplastic pollution in water are mounting, prompting the search for effective removal strategies. As we celebrate Earth Day on April 22 with the theme Planet vs. Plastics, we focus on microplastics in water and the challenges of removing these tiny pollutants. Microplastics are tiny plastic particles, typically less than 5 millimeters in size. They are either manufactured — for example, microbeads used in personal care products, microfibers in textiles, or pellets used in plastic production ─ or th ..read more

Seven Seas Water (Aruba) VBA will construct a new seawater reverse osmosis (“SWRO”) plant, contributing a total of a minimum of 16,500 cubic meters of daily drinking water per day. The new plant will be part of WEB’s long-term plan and the Water Roadmap to meet continued demand for water and will replace a temporary water production facility ..read more

Dissolved air flotation has a long list of advantages and suitable applications Dissolved air flotation (DAF) is a leading wastewater treatment method known for its efficiency and versatility. Unlike conventional clarification processes, DAF utilizes fine air bubbles to remove suspended solids, fats, and other contaminants from water or wastewater. It can be used for resource recovery or tertiary treatment, but it’s more typically used for clarification of wastewater as a pretreatment stage, and the benefits are numerous. Let’s delve into why DAF stands out and its diverse applications across ..read more

Champion peace and well-being by promoting access to clean water for all World Water Day 2024 is dedicated to the theme “Water for Peace,” emphasizing the crucial role that water plays in global stability, cooperation, and conflict prevention. The theme highlights equitable access to water resources as a basic human right and the role this plays in fostering peaceful societies. As we celebrate World Water Day on March 22, we invite you to join Seven Seas in the global movement for collective action to promote peace and well-being by ensuring that everyone has equal access to safe drinking wate ..read more

(Antigua and Barbuda) – The Antigua Public Utilities Authority (APUA) and Seven Seas Water Group (SSWG), a multinational provider of Water-as-a-Service® (WaaS) solutions, jointly announced today the signing of a 12-year Build-Own-Operate-Transfer agreement. Seven Seas Water Group will construct two new seawater reverse osmosis (SWRO) plants, contributing a combined total of three million imperial gallons of daily drinking water production capacity to the people of Antigua. The new plants will be strategically located adjacent to the existing facilities at Ffryes Beach and Ivan Rodrigues, utili ..read more

Empowering women contributes to a more sustainable and resilient future for water management Women have made significant contributions to science, technology, engineering, and mathematics (STEM) fields, but a gender gap persists, especially in disciplines related to water and wastewater sciences. Addressing this gap is crucial for fostering diversity, innovation, and inclusivity in the water industry. As we celebrate International Women’s Day on March 8 with the theme #InspireInclusion, we highlight the achievements and contributions of a remarkable woman, Malin Falkenmark, a Swedish professor ..read more

As the need for new water and wastewater infrastructure grows, P3s with an experienced private partner can make plans a reality A public-private partnership (P3) is a long-term collaboration between a government or public-sector entity and a private sector institution, which has the goal of providing a service usually provided by the public sector. The partnership involves the sharing of resources, risks, and responsibilities in the delivery of a public service or infrastructure project. Public-private partnerships are often used to build public infrastructure such as schools, hospitals, roads ..read more

Facilitating collaborative agreements with municipal customers A water sector public-private partnership (P3) is a long-term agreement between a public entity, like a municipal water utility, and a private water treatment company to deliver water or wastewater assets as well as the operation and maintenance services to support them. Two of the most popular P3 structures are the build-own-operate and build-own-operate-transfer contract models, although P3s have many other approaches. P3s allow public partners to shift risk to a specialized company that is better prepared to manage it. They remo ..read more

Several factors must be considered when choosing between conventional activated sludge and MBR wastewater treatment Wastewater treatment is one of the foundations of sanitation and hygiene and can play a major role in preserving aquatic ecosystems and conserving supplies of fresh water. What are some of the differences between two popular wastewater treatment methods, the membrane bioreactor (MBR) and activated sludge processes? Activated Sludge Treatment Conventional activated sludge (CAS) is a well-established and proven biological technology that has been used to treat municipal and industr ..read more

Membrane bioreactors remove pollutants with advanced technology Membrane bioreactors (MBR) use a combination of biological and membrane filtration processes to provide advanced wastewater treatment, resulting in high-quality effluent. As with conventional treatment, MBR technology uses microorganisms to break down organic pollutants, but unlike traditional methods that rely on a clarifier to remove solids, MBR systems use membrane filtration to screen out the suspended solids, letting high-quality treated water pass through. Since there is no need for a clarifier, MBR systems typically have a ..read more
