Continuous filtration to meet irrigation standards

Waste water

The Katamiya Dunes wastewater treatment plant in Egypt needed to improve effluent water quality for irrigation of a local golf course and surrounding areas. Following a successful pilot project with a DynaSand filter, plant operators decided to install a tertiary treatment stage. The staged project involved an initial build of eight filters, with an additional four being added a few years later.

Compact primary settling tanks for Hong Kong cavern project

Waste water

An innovative project in Hong Kong will relocate the ageing Sha Tin sewage treatment works into caverns nearby. Several issues with the existing site will be resolved including the availability of 28 hectares of land that can be repurposed for beneficial uses.

DynaSand filters solve micropollutant problems

Waste water

Water

The wastewater treatment plant in Baden-Baden, Germany, needed to add a highly efficient fourth treatment stage to significantly reduce micropollutants in the site’s effluent. The average flow through the plant is 4’700 m³/h and any new process needed to have sufficient capacity for peak flowrates.

Sulzer tertiary treatment delivers class A irrigation water

Waste water

Water

A wastewater treatment plant (WWTP) in Spain has completed a project to expand its capacity and improve effluent water quality at the same time. The installation of additional filtration equipment from Sulzer has enabled the plant to meet Class A water standards, allowing it to be used for irrigation and support local agriculture with a sustainable source of water. The project has enabled the WWTP to be the first in Spain where a tertiary treatment has achieved Class A water quality for irrigation.

Boosting micropollutant removal from wastewater

Waste water

Water

The first long-term trial in Germany of a continuous granular activated carbon (GAC) filter using ferric salts dosing immediately before filtration has delivered conclusive results. The pilot project used three DynaSand carbon filters, two with coagulant dosing and one control. All three filters were filled with approximately five tonnes of GAC. The results showed that it is possible to achieve a Ptot level of <0.2 mg/l, which would pass some of the most stringent water quality standards in the world.

Cutting phosphorus levels in wastewater effluent

Waste water

Water

In Sweden, treated water from the Sundet wastewater treatment plant has historically been released into the Norra Bergundasjön lake. Due to a very sensitive lake, a significant reduction in phosphorus was required. DynaSand® filters offer a very effective solution that enabled the plant to significantly reduce phosphorus levels below some of the most stringent targets. The DynaSand filters have consistently delivered lower phosphorus content than the 0.2 mg/l consent, with effluent concentrations regularly below 0.1 mg/l.

Reducing micropollutants in water

Waste water

Water

Wastewater treatment plants (WWTPs) are sources of organic micropollutants in waterways, making it important to improve the efficiency of removal processes and reduce their environmental impact. In Weißenburg, Germany, a pilot project is comparing the effectiveness of granular activated carbon and sand filters to boost filtration efficiency after ozonation.

Reducing micropollutants with DynaSand filters

Waste water

Water

In Germany, wastewater treatments plants (WWTPs) that discharge into the River Isar need to meet strict effluent standards for suspended solids and micropollutants such as nitrogen and phosphorus. In Freising, the plant has been equipped with DynaSand filters that enable the site to meet the latest requirements and protect the sensitive local environment.

DynaBelt belt filtration strengthens primary treatment and stabilizes suspended solids removal

Waste water

A municipal wastewater treatment plant in Apulia is undergoing an upgrade program of its headworks and primary treatment line. As part of the interim improvements, the plant required a robust, compact solution to enhance suspended solids (SS) removal in the primary sedimentation stage while maintaining operational continuity at variable flows.

Meeting the future challenges of water treatment today

Waste water

Water quality legislation is being tightened globally. The most precious resource on the planet is suffering from contamination and countries around the world are drawing up new regulations to tackle this challenge. It is the responsibility of municipalities to deliver the new standards and, in most cases, that will require additional treatment processes to be implemented.

Attaining the highest standards in water quality with modern filtration systems

Water

Phosphorus is an essential nutrient for all living organisms, but its presence in excessive quantities in water bodies poses significant environmental challenges. Its runoff into lakes and rivers, as well as its discharge from municipal and industrial wastewater, can lead to serious environmental consequences. As countries tighten their legislation on water quality, wastewater treatment plants may need to install additional filtration equipment to comply with current as well as future standards.

DynaSand sand filters for sea water pre-treatment in the UAE

Water

The two stage filtration with DynaSand filters is a pre-treatment facility to one of the large desalination plants located in Dubai, a part of the United Arab Emirates. The facility belongs to Dubai Electricity & Water Authority (DEWA) and was installed in 2007. It has been in commercial operation since 2008.

Removing pharmaceuticals from water supplies

Waste water

The current EU Urban Wastewater Treatment Directive is more than 30 years old, and it has made dramatic improvements to the water quality in European rivers, lakes and seas. However, several pollution challenges remain and are not covered by the current legislation. One of the most prominent is pharmaceutical residues, which are having a detrimental effect on wildlife and human health, leading to a revision of EU Directive 91/271/EEC.

Recycling water for agriculture in Bahrain

Waste water

Countries in the Middle East face a constant challenge with delivering sufficient water for an increasing population, both for drinking water and irrigation for agriculture. In Bahrain, the largest water treatment works in the country has undergone a huge redevelopment and Nordic Water, a Sulzer brand, has retrofitted the original sand filter basins with DynaSand filters. This, together with a recent expansion of the filtration systems, has enabled the plant to treat 250’000 m³/day for irrigation, the equivalent of 100 Olympic swimming pools every day.

PFAS in water

Waste water

The widespread use of per- and polyfluoroalkyl substances (PFAS) in domestic, commercial and industrial products has led to an environmental challenge that is now attracting the attention of European legislators. Often referred to as ‘forever chemicals’ because of their persistence in the environment, these common substances are increasingly being investigated for their potential impact on health. Developing solutions to remove these chemicals is increasingly important as more legislation is proposed.
