ZLD system

Degrémont Technologies is the water treatment specialist within Suez Environment. The company will exhibit its Zero Liquid Discharge (ZLD) system, which completely removes dissolved solids from wastewater and returns clean water to the process. Reverse osmosis may be used to concentrate the waste stream and return the permeate to the process. In this case, a much smaller volume (the reject) will require evaporation. In many cases, falling film evaporation is used to further concentrate the brine prior to crystallization. Degrémont Technologies,www.degremont-technologies.com, Booth 6330

Screens, filtration

OVIVO USA (formally known as Eimco Water Technologies) specializes in the development and worldwide marketing of coarse and fine screening, in-line filtration, raking machines, continuous automatic tube cleaning and fish protection systems for power plant cooling water intakes. Products on display will include the Brackett Green Dual Flow and Dual Flow Conversion Band Screens. OVIVO USA, www.ovivowater.com, Booth 7422

Pressure pipe

Hanson Pressure Pipe is a manufacturer of highly engineered concrete and steel pressure pipe systems. The company has more than 80 million feet of pipe in service today. Its Prestressed Concrete Embedded Cylinder Pipe is designed in accordance with AWWA C304 and manufactured in accordance with AWWA C301. Prestressing is achieved by helically wrapping, under measured tension and at uniform spacing, a high tensile strength wire around the concrete core. The pipe is manufactured in diameters from 36” to 144”. Availability of diameters and laying lengths varies by location.
