REVERSE OSMOSIS
It is a technology that is used to remove a majority of contaminants from water by pushing the water under pressure through a semi?permeable membrane. Osmosis is a naturally occurring phenomenon and one of the most important processes in nature. It is a process where a weaker saline solution will tend to migrate to a strong saline solution. Examples of osmosis are when plant roots absorb water from the soil and our kidneys absorb water from our blood.
Reverse osmosis plants require a variety of pre-treatment techniques including softening, de-chlorination, and anti-scalent treatment. Following pre-treatment, high levels of pressure send water through a semi-permeable membrane, which retains all contaminants but it lets pure water pass through. Energy requirements depend on the concentration of salts and contaminants in the influent water, higher concentrations require more energy to treat.
SALIENT FEATURES
- Produces high-quality dematerialized water.
- Most modern membrane technology.
- Modular design.
- Low water-rejection rate.
- Low operational and maintenance costs.
TASTE & ODOUR CONTROL
Source water protection involves the prevention of contaminants from entering the source. Surface water or groundwater may become contaminated by pollutants such as gasoline, industrial solvents or a wide variety of volatile organics. The removal of contaminants from surface water or groundwater is costly and may involve the use of aeration, powdered activated carbon, or both. If taste and odour must be controlled at the treatment plant, oxidation, aeration and adsorption can be effective in reducing taste and odour, and improved coagulation filtration.
As public drinking water quality has come under more scrutiny in recent years, reverse osmosis (R.O.) systems have become increasingly popular in homes and businesses as alternatives to costly bottled water and water delivery services. R.O. systems remove unwanted contaminants, bad tastes and odours from drinking water by forcing municipal or well water through a semipermeable membrane.
Generally if odour exists, it should be removed prior to under-sink or whole house RO systems for best results and to avoid problems with fouling of the RO system.While H2S can pass through the membrane as a gas and removed after the RO membranes, it is best practice to remove it prior to the RO system.Often the odour is a result of a dissolved gas, and gasses will pass through the RO membrane. If the well water has hydrogen sulphide odours, and it is not treated prior to the RO membrane, it can cause problems with slime and build-up on the RO membranes if hydrogen sulphide oxidizes and/or there are sulphur bacteria present.
RO ‘systems’ can remove odours if part of the system is an oxidation filter, carbon filter, aeration or other component that can remove odour. RO membranes by themselves do not remove odour.
ADDITIONAL BENEFITS OF USING A REVERSE OSMOSIS SYSTEM
Peace of mind about quality and better tasting water aren’t the only benefits you get from reverse osmosis drinking water. By adding a reverse osmosis system to your home, you could find your family stays hydrated and makes healthier choices! It’s been said that better tasting water can help families cut down on sugary drinks.In addition to better tasting water, you’ll notice that your food and coffee taste better because you’ve used filtered water. Plus, you’ll stop wasting money on bottled water, and you’ll get crystal clear ice cubes.
