It is estimated that 70% of all industrial processes use reverse osmosis (RO) water treatment to improve process water quality or to treat waste streams prior to discharge.
Desalitech offers standardized containerized systems for clean water production and industrial water treatment. Desalitech’s Closed Circuit DesalinationTM (CCDTM) technology guarantees operation to maximum recovery in efficient, simple, single-stage units. Recovery rate and system performance can be adjusted at the control panel, providing the flexibility to adapt system performance to changing conditions. In addition, CCD technology is more robust against fouling and scaling. This competes well with conventional industrial water RO processes in which recovery is limited, expensive custom-built multiple-stage arrangements are required, and membrane maintenance can be a significant challenge.
High water quality for power and steam production, cooling systems, food and beverage, textiles and electronics, oil and gas, agriculture, etc., greatly contributes to smooth, reliable operation. Water reuse is becoming increasingly desired to abate the environmental impacts of waste effluents and as a means to decrease demand for new water supplies.
Desalitech offers complete, ultra-low energy, high recovery industrial water RO units that dramatically reduce energy consumption while providing unmatched operational flexibility to accommodate the wide variations in conditions that are typical for these water sources. Major advantages include:
ü Maximum Recovery – Brine disposal in industrial RO applications can be exceedingly expensive. Any Desalitech unit can attain ultimate recovery in a single stage, thereby minimizing source water waste, pretreatment costs, brine disposal expenses and extra equipment costs. Recovery is limited only by the scaling characteristics of the specific source water, and even this limitation is addressed by the salinity cycling that enables CCD systems to achieve much higher recovery rates than conventional RO systems. Desalitech’s RO units have desalinated low salinity industrial water sources at over 97% recovery.
ü Reduced Membrane Fouling and Scaling - The high cross-flow and brine salinity cycling inherent in the CCD process inhibit fouling and scaling, resulting in decreased maintenance procedures and expenses and enhanced system reliability. This is important for any RO unit, and especially important for high recovery and water reuse systems.
ü Reduced Equipment Costs - As a result of needing fewer membrane elements and doing away with multiple stages and boosters systems, capital costs can be dramatically reduced.
ü Unmatched Operational Flexibility - Process flexibility is especially important for the variable salinity sources and variable operating conditions typically found in many industrial water treatment applications. Desalitech industrial units have operated continuously and automatically in situations characterized by intense seasonal variations.
ü Reduced Energy Consumption - Desalitech industrial systems reduce energy consumption by 35% compared to modern conventional desalination systems.
