Her father was the procurement officer for the Narragansett Bay Commission, which provides wastewater treatment in Providence.
Wen Yibo controls Shenzhen-listed Sound Environmental Resources and Hong Kong-listed Sound Global, both of which provide wastewater treatment and water supply systems.
Waste stabilization ponds (WSPs) have been used extensively to provide wastewater treatment throughout the world.
Another specially promising solution is related to the construction of phenomenological models that provide wastewater influent profiles in accordance with data about the catchment properties (number of inhabitant equivalents, sewer network, type of industries, rainfall and temperature profiles, etc.).
The City provides wastewater services for residents and transports wastewater to the regional Hampton Roads Sanitation District treatment plants.
Epuramat, based in Luxembourg, also works with municipal and industrial clients providing compact wastewater treatment facilities and oil-water separation systems.
Decentralised systems also offer an alternative approach to providing water, wastewater and storm water services to urban areas (Nhapi 2004a, b, c; Libralato et al. 2012).
Membrane Bioreactor (MBR) technology is widely accepted today for wastewater treatment providing superior effluent quality, opportunities for water reuse, smaller footprint, and better process control.
When compared to alternative technologies, the DOC system provides high wastewater recovery (>95%), at low energy cost (<90 × 103 J/l (25 Wh/l)), with minimal resupply (<20 kg/year).
With this adoption, exceptional TN removal (85% on average) was achieved under a high nitrogen loading rate (NLR) of around 28 g N m− 2 day− 1, which makes the proposed system an adequate option to provide advanced wastewater treatment for peri-urban communities and rural area.
