Mobile water treatment can play a key role in a power utility’s overall water management strategy. Today, portable solutions are able to cover emergency, temporary or long-term water treatment needs. Mobile units can be deployed as stand-alone units or in combination to form complete systems with state-of-the-art purification technologies.
The flexibility and cost-saving potential of temporary mobile water treatment solutions have encouraged growth within the industry. As an example, Veolia Water Technologies has strengthened its “anytime, anywhere” water treatment capabilities by adding 600 and 900 gallon per minute (GPM) reverse osmosis (RO) units to its mobile water services fleet.
Veolia Water Technologies has strengthened its “anytime, anywhere” water treatment capabilities by adding 600 and 900 gallon per minute (GPM) reverse osmosis (RO) units to its mobile water services fleet.
The new mobile RO rentals can operate in either single- or double-pass orientation, with flows ranging from 100 GPM up to 900 GPM. The systems are fully automated and come complete with clean-in-place capabilities to meet water purity requirements with a minimal amount of manpower.
The 900 GPM High Recovery RO technology relies upon a patented design and operating function to provide higher recoveries and higher permeate flux rates than traditional RO technology. Through a closed-circuit recycling of the RO feedwater, the membranes are less susceptible to fouling by water impurities and are able to capture up to 95% as permeate, reducing needed pretreatment capacities and saving valuable water.
Potential applications served include physical and chemical separation for suspended solids, turbidity, hardness and metals; and membrane separation and demineralization for total dissolved solids reduction, specialty ion exchange and heavy metals removal.
According to Michael Reyes, Veolia Mobile Water Services national sales manager, the two technologies most often deployed to power generation sites are the RO units and the Actiflo Turbo clarification trailers. The mobile Actiflo typically provides river water treatment, the first step in boiler feedwater processing, as well as in-process water and wastewater treatment for ash basins, coal combustion residual (CCR) impoundments, and secondary or tertiary clarification.
Actiflo Turbo technology uses a patented draft tube design to flocculate incoming solids with proprietary microsand. The dense microsand acts as a ballast as flocculation occurs, dramatically increasing the settling rate of the solids. This results in excellent solids/metals separation. Hydrocyclones separate the sludge from the microsand and recycle it back into the unit, adding to the sustainable operation of the unit by minimizing sludge volume.
Whether for emergencies, planned temporary deployments or long-term rentals, mobile water systems are becoming a reliable and effective solution for a variety of water management needs. IWW
