Skid Mount Seawater Desalination Systems (1500gpd Package Shown)
Integrated Skid Mount RDWS-WH-SWRO Sea Water Desalination Purification Equipment
The RDWS-WH-SWRO Sea Water Skid Series is a complete sea water desalination purification water system, pre-assembled and shipped on a single skid for quick and easy installation and start-up. The system consists of hard water & silica pretreatment, sand & sediment pretreatment uv bacteria disinfection, re-pressure delivery pump, and off-skid 300 gallon storage tank. The RDWS-WH-SWRO Make-Up Water Series is pre-engineered allowing quick assembly and delivery. With simple utility connections and pretreatment set up, the system is virtually ready for on-line service, saving customers both time and money.
Built-To-Order: There are significant differences in the equipment used for removing most of the dissolved solids from Sea Water & Oceans and from most surface or well waters. Seawater units are referred to as Desalination Systems 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 an equivalent gallon output RO unit.

Complete customization specifically for sea water sources! Step-by-step purification processes included on stainless steel skid platform:
On Skid Pretreatment: Antiscalant Injection System - pre-treats and protects seawater RO membranes from hard water scale & build up, silica, and highly mineralized water. The antiscalant formulation has been certified by the National Sanitation Foundation (NSF) under ANSI/NSF Standard 60 for use in producing potable water and is considered low maintenance as a salt-free system with no discharge or waste water drain lines.
On Skid Pretreatment: Automatic Self-Cleaning Sediment Filter - High capacity sediment, sand, dirt, and debris backwashing filter with a no-maintenance design and user-friendly accommodations. *No-maintenance refers to no added salts or chemicals and no routine replacements!
On Skid UV System: The final pretreatment stage to ensure safe water and inhibit bio-fouling seawater RO membranes. Chemical free, inexpensive, and environmentally-friendly disinfection for high purity water applications.
On Skid RDWS Feature: Pretreatment lock out switch and manual bypass for the automatic backwashing filter. Designed to protect the desalination system so unfiltered water does not reach the seawater RO membranes while the pretreatment filter is backwashing.
On Skid Desalination: High capacity, high rejection, low energy seawater desalination membranes from 750gpd to 2,500gpd. Our high quality desalination systems include a recirculation valve for higher recovery, automatic membrane flush upon start up, and microprocessor based controller to ensure optimum performance. Integrated float switch conserves water and system life by shutting off the RO system when storage tanks are full.
OFF Skid Storage Tanks: One (1) or two (2) of our 300gal atmospheric storage tanks. Tanks measure 35" diameter by 81" height. Float installed in tanks to conserve water and system life by shutting off the desalination system when the tanks are full. *Tanks installed separately from skid - different sizes or no tanks can be quoted upon request.
On Skid Delivery Pump: 10gpm @ 48psi fully automatic electric repressurization pump designed to draw water out of the storage tanks and to your applications.
These Sea Water Desalination SKID Systems also include Free Wood Crating for safe delivery and Free Shipping within the Continental US!
Quality Assurance: Our engineers have held to the goal of over build and over design. That is why we are constantly surprised at how long the membranes last in our systems and how few calls we get about premature pump or other system failures. It's also why we primarily use stainless steel in our structures instead of aluminum or powder coated mild steel on most of our systems. It costs a bit more but the benefits in durability and reliability are well worth it! Let RainDance Water Systems provide your company with a long lasting membrane water purification solution.
