Introduction: Alternative Water Resources

• Greater Efficiency• Wastewater Reuse

• Desalination

The world is running out of cheap clean water and increasingly resorting to alternatives.

Introduction: Reverse Osmosis

Reverse Osmosis (RO) is the standard for water purification & reuse, but RO is a 40 year old

technology subject to inefficiency and failure.

Desalitech’s new RO process has solved the limitations of traditional RO, saving up to 80%

and making operation easier and more reliable.

Desalitech serves industry leaders around the globe.

Current State of Reverse Osmosis

Membrane fouling and scaling accounts for 4 out of 5 reverse osmosis failures.

Current State of Reverse OsmosisIncreasing recovery from 75 to 95% provides quick return on investment

75% Recovery($/kgal)

Traditional Reverse Osmosis

Permeate Throttle Between Stages

Fouling of Lead Elements

Scaling of Tail Elements

Inefficiencies/Limitations:1. More than 50% recovery requires multiple stages. 2. Multi-staging increases complexity and is hard to balance.3. Fouling of lead elements, scaling of tail elements.4. High-pressure pump operates at peak pressure 100% of the time.

Simple or Dead-End Filtration

SimpleFiltration

CrossflowFiltration

Higher water efficiency

How it Works:• Feed recirculation + feed

flushing• Recovery increases with each

concentration cycle.• Membrane cross flow by low-

horsepower circulation pump.• Brine release triggered by one of

several set points. • Recovery is achieved in time,

not space.• Recovery, crossflow and flux

independent control panel settings.

CCD™ Reverse Osmosis – The New RO

Benefits/Value:• Unlimited recovery in a single

stage.• Feed flushing disrupts scaling

and biological growth.• Reduced energy consumption

as CCD systems “hug” the osmotic curve.

• Ability to utilize multiple set-points provides unmatched flexibility/reliability.

• Standard RO components in a patented process design.

• The first major breakthrough in RO in decades
