H3500 Reverse Osmosis

What Is Reverse Osmosis?

Reverse Osmosis H3500The real flavor of water refreshes and satisfies. But today, enjoying a drink of water may not be as simple as filling your glass from the tap. Even when treated by an approved municipal water system, the goodness of water is often marred by minerals, organic matter or chlorine.

Reverse Osmosis is a filtration process used for water. It works by using pressure to force a solution through a membrane, retaining the solute (dissolved solids) on one side and allowing the treated solvent (water) to pass to the other side.

The membranes used for reverse osmosis water systems have a dense barrier designed to allow only water to pass through while preventing the passage of solutes (such as salt ions). This process requires that a high pressure be exerted on the high concentration side of the membrane.

Features For Quality Drinking Water:

  • Designed for maximum water cleaning efficiency with no operating costs except for periodic replacement of disposable filters
  • Efficient on water pressure as low as 30 psi
  • Non-electric operation
  • Up to 33% more tank pressure for increase flow and volume
  • Fills holding tank up to 5 times faster than other systems
  • Membrane technology consistently reduces up to 99% of total dissolved solids (TDS)
  • Includes a long-reach dispensing spigot with air gap
  • Completely pre-tested with a 25-year limited warranty

Water Contaminant Reduction:

The H3500 reverse osmosis water softener also reduces contaminants found in a household's water supply such as:
Arsenic (Pentavalent) <=50 ppb, Barium, Cadmium, Cyst, Fluoride, Chromium (Hexavalent), Lead, TDS, Chromium (Trivalent), Nitrate/Nitrite, Radium 226/228and Selenium

Reverse Osmosis Water Systems

There are many types of reverse osmosis water systems.

Reverse osmosis filter water systems produce pure water by forcing untreated water or tap water through a semi permeable membrane. Reverse osmosis can provide your home or business with healthier drinking water and protect you against low quality water that you may receive from a well or your public water pipes.

The Hague H3500 Reverse osmosis water system enlists a five-stage process that begins with a dual-function pre-filter; a combination sediment filter and carbon to prevent the membrane from clogging and chlorine degradation. The water then flows under pressure from the non- electric permeate pump into the RO module where product water is separated from impurities. Product water moves on to the Prolong Contact Filter and purities go to drain. Additional organics and gases are removed from the product water during the prolong contact stage.
Product water is then stored in the holding tank until needed. When water is drawn from the tank, it passes through a final carbon post filter to ensure a fresh polished taste as it fills your glass.

Care must be taken when deciding on reverse osmosis water filtration; most reverse osmosis water systems employ a three or four stage process. Hague makes the extra effort with a five-stage system to provide you with the highest quality water. Installation is critical to ensure maximum performance. Sanitary precautions must also be taken when installing a reverse osmosis system as not to contaminate the system.

Of the several reverse osmosis water systems to chose from, a Hague H3500, coupled with a Watermax water softener is the only system to actually filter your water 9 times before it ever reaches your lips.

Reverse Osmosis Water Filtration

Your water can be divided into three groups;

  • Working water, water used to wash your car, water the grass etc.
  • Utility water, water used for washing clothes, dishes, bathing.
  • Life support water, water used for drinking and preparing food.

At Hague we recommend using reverse osmosis water filtration to provide your family with high quality life support water.

Reverse osmosis water filtration typically includes several steps:

  1. A sediment filter to trap particles including rust and calcium carbonate from the water supply. The Hague H3500 RO system employs a dual function pre filter  which also contains activated carbon, to trap organic chemicals and chlorine, which will attack and degrade TFC (Thin Film Composite)  reverse osmosis membranes
  2. The second stage of reverse osmosis water filtration is a semi permeable reverse osmosis (RO) filter which is a thin film composite membrane (TFM , TFC or CTA)
  3. Reverse osmosis water filtration may be used on well or municipal water. For municipal water which is typically treated with chlorine a cellulose triacetate membrane (CTA) is used. The CTA membrane is prone to rotting unless protected by chlorinated water, while the TFC membrane is prone to breaking down under the influence of chlorine.
  4. The next stage of the H3500 reverse osmosis water filtration is the prolong contact filter. This is a “polishing” stage where any remaining chlorine or organics are removed from the product water.
  5. From the prolonged contact stage, the water is stored in the holding tank until needed.
  6. Once the water is drawn from the holding tank, it passes through a final carbon post filter. This is to ensure any taste that may have been picked up in the holding tank is removed before use.

At Hague we recommend that a reverse osmosis water filtration system be preceded by a Watermax water softener. Softened water will greatly extend the life of your reverse osmosis water filter.

Reverse Osmosis Water Filter

The reverse osmosis water filter is actually a series of filters. In the case of the Hague H3500 reverse osmosis water filter, there are four filtering stages.

Stage one of the reverse osmosis water filter is a dual function pre-filter that uses a combination of sediment filtration and carbon to protect the RO membrane from particulate matter above 5 microns and damage from chlorine.

Stage two of the reverse osmosis water filter sends the water through the reverse osmosis membrane.

This semi permeable membrane allows water molecules to pass through, while dissolved mineral salts or total dissolved solids and virtually all particulate matter, even viruses, are left behind. In essence, the membrane acts as a super fine "strainer."

Stage three of the reverse osmosis water filter is the prolonged contact carbon filter to further improve the taste of the water.

Stage four of the reverse osmosis water filter is known as the post carbon filter and consists of a carbon block giving your glass of water a fresh crisp taste.

Regularly scheduled replacement of the four reverse osmosis water filter mentioned above is recommended. Replacement time frames range from 6 months to three years and vary depending upon the filtering stage.
