NATURECLEAN - EEC REVERSE OSMOSIS
SEA – BRAKISH – FRESH WATER RO – UF DRINKING WATER PLANTS - UV DISINFECTION
ASSURED QUALITY DRINKING WATER
Develop New Water Resources
In a single step, NATURECLEAN - EEC DESAL filters, softens and disinfects brackish and seawater resources to produce water that easily meets the WHO's regulations on surface water treatment and safe drinking water. NATURECLEAN - EEC DESAL clears away naturally occurring organics and minerals, as well as contaminants from pollution. NATURECLEAN - EEC DESAL effectively reduces salts, hardness, nitrates, pesticides, color, bacteria, viruses, and the precursors of disinfection byproducts.
1. How Does It Work?
Diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration. Reverse Osmosis is a special case of diffusion in which the molecules are water and the concentration gradient occurs across a semi permeable membrane. The semi permeable membrane allows the passage of water, but not ions (e.g., Na+, Ca2+, Cl-) or larger molecules (e.g., glucose, urea, bacteria). Diffusion and osmosis are thermodynamically favorable and will continue until equilibrium is reached. Osmosis can be slowed, stopped, or even reversed if sufficient pressure is applied to the membrane from the 'concentrated' side of the membrane.

NATURECLEAN – EEC DESAL - RO System Design
Spiral-wound RO membrane elements are housed in cylindrical pressure vessels, with as many as seven interconnected elements per vessel. Vessels piped in parallel constitute a single hydraulic stage, which typically yields 50% recovery of product water based on the feed rate. The first-stage concentrate usually feeds one or more downstream stages. Two-stage systems yield about 75% recovery; three-stage systems yield about 85%, depending on concentrate chemistry. Pressure vessels are staged in a tapered array to provide adequate feed/concentrate flow rates and maintain proper differential operating pressures.

NATURECLEAN completely integrates trailer and skid-mounted systems for simple installation and operation. Standard units are alarmed for feed pressure and equipped for remote operation with automatic start/stop signals from a level-sensing switch at the product water tank. Standard components include 5-micron cartridge filter, multistage centrifugal feed pump and conductivity meters. Options include PLC control, additional alarm points, pH meter, control, clean-in-place (CIP), chemical addition subsystems, variable frequency drive pumps, remote monitoring and comprehensive SCADA packages to enhance system analysis interface.

2. PROCESS DESCRIPTION
Pretreatment
This procedure is typically required to insure stable, long-term RO system performance and membrane life. In general, surface, sea and wastewaters require more pretreatment than well water supplies. Pretreatment may include clarification, filtration, ultra filtration, pH adjustment, removal of free chlorine, antiscalant addition and 5-micron cartridge filtration
Reverse osmosis occurs when the water is moved across the membrane against the concentration gradient, from lower concentration to higher concentration. To illustrate, imagine a semi permeable membrane with fresh water on one side and a concentrated aqueous solution on the other side. If normal osmosis takes place, the fresh water will cross the membrane to dilute the concentrated solution. In reverse osmosis, pressure is exerted on the side with the concentrated solution to force the water molecules across the membrane to the fresh waterside.

Each System is Fully Tested Before Leaving Factory
NATURECLEAN custom designs systems; for certain application, pre-fabricate RO plants for fast delivery and easy integration into any new or existing water treatment facility. With a single electrical interface and the necessary hydraulic connections, NATURECLEAN systems are on line delivering demineralized water at capacities from 50 gpm to millions of gallons per day.
