Learn how Sentec developed calibration free agricultural flow meters in record time boosting accuracy reducing waste improving yields and supporting sustainable farming

Tasked with transferring water from settling ponds to a frac pond for project in mid-Western U.S., a specialist water provider to oil and gas drilling companies needed a pump capable of handling a complex operation through a seven-mile-long steel pipeline.

Dŵr Cymru Welsh Water’s Hirwaun water treatment works is a small works (5Ml/d) which treats raw water from the Penderyn upland reservoir. Treatment is by coagulation with ferric sulphate and lime, flocculation and clarification by DAF. The clarified water is dosed with lime and this is followed by first stage filtration in four rapid gravity filters, intermediate electrochlorination and orthophosphoric acid dosing, and second stage filtration in four pressure filters. Final disinfection is by electrochlorination. The original electrochlorination plant was an Evoqua OSEC® packaged unit installed over twenty years ago and had reached the end of its asset life.

A large UK private utility company responsible for providing public water supply and wastewater treatment to the majority of southern England recently approached Xylem to enquire about what it could offer to improve or restore the performance on their Sanitaire fine bubble diffused aeration systems.

Faced with high standards for both efficiency and sustainability, Averdung and the municipal utility sought a partner capable of realizing this supply through seawater source heat pumps using Baltic Sea water.

This guide, developed in partnership with AWWA, explores how utilities can adopt data-driven pipeline management strategies and features real-world utility success stories. Learn more about assessing pipelines and leveraging data to prioritize and address risk.

At the start of 2021, the plant registered a decrease in air flow, accompanied by an increase in energy consumption by the blowers. Personnel suspected that the diffusers were clogged by calcium carbonate build-up from the water, causing significant head loss in the diffusers.

In 2016, EPAL recognized a deviation in the non-revenue water (NRW) trend since implementation of the DMA program. The issue was promptly identified in two supply zones, encompassing 150 kilometers of water transmission mains, predominately composed of large diameter reinforced concrete pipe built in 1965.

Regulate and monitor pressures, supervise flow rates, consumption, and non-revenue water (NRW) in different sectors, and bring together system information from various sources including the SADM’s SCADA.

The estimated flow through this regulator was 85 MGD, with a combined plant capacity of 170 MGD. Local environmental regulations restricted the use of diesel engines to 175 HP or less, and all engine driven equipment was required to be sound attenuated to 50 decibels at 30 feet.

In search for the best wastewater treatment process in terms of removal of microbiological contaminants and the abatement of bromate discharge, RWTH Aachen University, along with the other environmental institutions, launched a research project and partnered with Xylem to test the effects of wastewater ozonation on water quality and its ecosystem.

New building codes continue to raise efficiency standards for new and existing buildings; economic conditions pressure organizations to cut energy costs wherever possible; and new corporate sustainability initiatives require steady efficiency improvements.

Xylem built a coal ash disposal solution that met regulatory requirements while controlling labor and fuel costs.
