Waste Water Case Studies

Thermo Energy Corporation

ThermoEnergy Corporation is a public company based in Worcester, Massachusetts, and is engaged in the design and manufacture of equipment that treats wastewater. The company has more than 85 systems in operation around the world that treat wastewater containing metals, ammonia, sugar, glycol, and high dissolved solids typical of produced water in the hydrocarbon industry.

The basis of the technology is a vacuum-assisted flash evaporative process that is suitable for very high dissolved solids wastewater, but due to the unique design, consumes little energy. Typically, the company works with its customers to understand the flow rates and wastewater constituents, then designs a system to produce very clean water, while capturing the solids in the water for re-use or disposal.

AECOM Water Treatment, Hong Kong

The Sha Tin Water Treatment Works in Hong Kong has a design capacity of 1.2 billion liters per day. It supplies treated water to more than two million people in a part of urban Kowloon, and the entire Hong Kong Central and Western districts. This is roughly more than 30 percent of the Hong Kong population.

Due to the rising water demands of society, the Hong Kong Special Administrative Region government wanted to reconstruct and upgrade the section to offer a more reliable and high-quality water supply. AECOM was appointed by the Water Supplies Department (WSD) to provide detailed design and construction supervision services, as well as to develop a landscape framework, master plan, and the final layout plan for the ultimate stage of this challenging project. The project is scheduled for completion in early 2019.

Food Chain Reactor for Treating Wastewater

Organica’s Fixed-Bed Biofilm Activated Sludge (FBAS), uses natural (plant) and artificial (biofiber media) root structures to provide a habitat for diverse fixed-film bacterial cultures that metabolize the contaminants in wastewater. Organica treatment plants are up to 50% smaller than conventional activated sludge plants and populated by over 3,000 species of microbes, aquatic flora, and fauna.

The complete wastewater treatment solution – from solids removal, biological treatment/nutrient removal, phase separation to final treatment for reuse quality – is incorporated inside a single structure. Intelligent process control allows very flexible and highly automated low-cost operation. The facilities are designed for trouble-free maintenance and manageability.

The botanical garden-like setting and odorless solution allow Organica plants to seamlessly integrate into the urban landscape, for example in Shenzhen, China, surrounding residential buildings.

Wetlands for wastewater treatment - City of Lakeland, FL

Located northeast of Mulberry, Florida, the Wetland Treatment System is over 1600 acres of uplands, hardwood swamps, emergent marshes, and open-water lakes. The Wetland system accepts the treated wastewater from the City of Lakeland, processes that water, and then discharges it into a tributary of the north prong of the Alafia River.
