WATER TREATMENT TECHNOLOGIES: CLOSED-CIRCUIT DESALINATION (CCD™)

Layne has partnered with Desalitech to provide simple, sustainable, and improved reverse osmosis solutions. CCD™ reverse osmosis (CCD-RO) is a patented process that maximizes permeate recovery, thereby reducing brine waste and conserving valuable water resources. CCD technology significantly reduces overall water treatment costs compared to conventional RO processes while increasing operational flexibility and reliability. CCD-RO systems, with a single stage of RO membrane elements, are capable of automatically adjusting to varying feed water conditions, while operating at a higher recovery rate than a traditional system with multi-stage RO membrane elements. This automated high-recovery operation is ideal for effective and efficient water treatment of industrial, inland and coastal water sources. MAXIMUM PERMEATE RECOVERY CCD-RO systems reduce brine waste while maximizing permeate yields, while also saving on pre-treatment capital and operational expenses. OPERATIONAL FLEXIBILITY Self-optimizing controls respond to source water variations automatically. REDUCTION IN ENERGY CONSUMPTION CCD-RO offers a considerable reduction in energy consumption of up to 15-20%. REDUCED OPERATING COSTS The operational flexibility of the CCD-RO helps reduce chemical usage, improves system reliability, and can minimize the Clean-In-Place (CIP), or membrane cleaning frequency, thereby saving on membrane related expenditures. REDUCED FOOTPRINT CCD-RO systems can utilize fewer membranes in fewer pressure vessels than conventional RO systems, thereby reducing footprint requirements. In addition, increased recovery can also reduce the footprint of the pre-treatment system. SYSTEM RETROFITS Plants that are retrofitted with the CCD process will greatly improve performance and reduce operating costs.

CCD™ PILOT TEST RESULTS Observations of a 50 GPM Demonstration Unit at Layne's Center of Excellence:

1) Treated municipal water is used in Layne's media regeneration process.

2) A CCD-RO unit was installed adjacent to the existing

conventional RO system to demonstrate the technology and provide a direct performance comparison. Layne's objective with the demonstration was to achieve higher permeate recovery rates, reduce the amount of brine concentrate discharged to the municipal sewer, and reduce energy consumption.

3) The existing RO system processed 67 GPM of feed

water to produce 50 GPM of permeate. The CCD-RO unit required only 56 GPM of feed water to produce an equal amount of permeate, resulting in a savings of 11 GPM of feed water supply and reduced energy costs. In addition, the amount of concentrated reject produced was reduced from 17 GPM to just 6 GPM — an almost 3X reduction.

4) The CCD-RO system has been operating for over a year,

cycling on and off automatically as needed to meet the facility's demand for purified water. Its performance has been highly reliable, without requiring membrane cleaning or unnecessary maintenance procedures.
