Salt Water Filtration : Sea Water
Purification & Ocean Water Desalination Systems
Use our salt water filtration units as your primary filtration system or
use as an emergency stand-by water filter unit. Learn how our selection
of small 500gpd to 24,000gpd light commercial sea water purification
systems can turn sea water into fresh drinking water for your home,
business, cottage, vacation home, or hotel.
The best known applications for the RO process is in
desalination, where fresh water is generated from seawater by removing
the salt. We offer both vertical
floor standing and complete skid mount desalination systems with storage
tanks and repressure pumps.
Land based sea water desalination equipment
designed for residential homes and commercial purification applications
such as seaside hotels, vacation rentals, island resorts, and emergency
back-up water source.
Not all reverse osmosis systems
provide the same filtration capabilities:
There are significant differences in the equipment used for removing
most of the dissolved solids from seawater and from most tap or
well waters. Seawater units are referred to as desalinators and
surface/well water units are called reverse osmosis (RO) units. The
laws of physics require approximately 1 psi driving force for each
100 mg/l of solids dissolved in the water to be treated. Seawater
has about 35,000 mg/l of dissolved solids so to obtain the first
drop of permeate water a pressure of 350 psi is required. Reverse
osmosis units on the other hand normally treat water where the
dissolved solids content is in the area of 6,000 mg/l or less. The
required pressure for that first drop of water for 6,000 mg/l is 60
psi. To insure an adequate flow of water from the respective devices
seawater units usually operate in the area of 1,000 psi and RO units
in a range of 150 to 250 psi. This additional pressure requirement
for seawater increases the required strength of almost all
components and requires much larger pumps. Also, seawater is
extremely corrosive so the materials of construction for seawater
units must be non-corrosive. All of these differences cause the cost
of seawater units to be much higher than the cost of a standard
reverse osmosis system.

Antiscalant system needed to protect the desal membrane
from hard water scale, silica and foulants.
Backwashing Pre-Filter - High performance sand, silt,
and turbidity pretreatment protection system.
UV Disinfection for Bacteria,Virus,Microbiological Water
- Why is pretreatment
the preservation of the efficiency and life span of a
desalination system installation, a sufficient
pre-treatment is required. A proper selection of
pre-treatment methods for feed water will improve
affectivity and extend the life span of the system by
preventing or minimizing organic fouling, scaling and
membrane plugging. Options include an automatic
antiscalant feed system and automatic sand filter to
provide premium pretreatment protection.

Water Desalination Purification Selection Guide & Price Quote Information
Desalination by Reverse Osmosis (RO) is a process whereby fresh
water is extracted from seawater through the use of a semipermeable
membrane. Prefiltration removes sediment, sand, and debris from the
seawater. Then, a high-pressure pump pressurizes the seawater to
approximately 800-1,000 psi. Thus, seawater is forced through a
semi-permeable membrane, which removes the dissolved solids and
produces fresh, potable water on the other side. This method rejects
at least 98% of salts, contaminates, and pollutants from seawater.
