Welcome To RainDance H2O: Residential Sea Water Treatment  & Commercial Seawater Desalination Systems

Brackish Salt Water Filtration : Sea Water Purification & Ocean Water Desalination Systems

Use our sea 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 750gpd to 4,000gpd residential home to 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 sea water desalination, where fresh water is generated from seawater by removing the salt.

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. 

Our Most Popular Sea Water Desalination Equipment Special Is Back!
Limited Time 750GPD RainDance H2O SWRO-750 Sea Water Package Includes: 
  • 750GPD High Capacity Sea Water Reverse Osmosis Water Purification System
  • RO Membrane Pure-Flush -Helps extend membrane life. Clean water flushes the membrane upon start-up flush away any accumulated particles or debris.
  • Pretreatment: High capacity sand, sediment and dirt prefilter 
  • Pretreatment: Ultraviolet UV Water Disinfection Pre-Plumbed with SS mounting plate on the right side of the frame - prevents possible bacteria, viruses, and bio fouling in the feed water.
  • Separate External Water Alarm - Senses Leaks
  • 300 gallon capacity storage tank - the water produced by the sea water reverse osmosis system comes out as a small stream, which is why you need a separate storage tank (at least 300 gallons storage or more) and a re-pressure pump to deliver the filtered water into your home
  • Float Switch
  • 10gpm delivery pump - Delivers water from storage tank to your application   
  • SWRO-750 Package Replacement Special Offer - RainDance H2O SWRO-750 Package will also include a *5 year replacement sediment filter package at no charge. Replacement Package Includes: 20 replacement sediment pre-filters *5 year supply of sediment filters when replaced every 3 months & a 5 year Replacement UV Bulb Package. UV Bulbs should be replaced every 12 months.

Sea Water Filter

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.

Why is pretreatment required? For 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.

Additional Comments:

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.
