DOMESTIC RO PLANT – Doulton Filtering System

DOMESTIC REVERSE OSMOSIS PLANT

To purify water using doulton filtering system Domestic RO Plant, the process of Reverse Osmosis is utilized. This method filters out impurities through a semi-permeable membrane, providing high-quality water without the use of chemicals or pollutants. This makes the RO Plant environmentally friendly and beneficial for health.

Reverse osmosis works by applying pressure to saltwater, forcing it through a membrane that retains contaminants and allows clean water to pass. The technology is widely recognized for its effectiveness in water purification, and doultonfilteringsystem offers top-quality RO Plants for both domestic and commercial use in Pakistan.Doultonfilteringsystem RO Plants are known for their easy installation, low maintenance costs, and minimal environmental impact, as they do not produce harmful substances. They are suitable for various applications, including homes, offices, and industrial settings.

REVERSE OSMOSIS WORKING

Reverse Osmosis (RO) is an advanced water filtration method that serves as an alternative to traditional osmosis. In an RO system, the process is reversed, and higher pressure is applied on the side with higher impurity concentration and salinity. This pressure can come from the water mains or be increased using a pressure pump.

An RO system typically consists of the following types of filters:

Sediment Filter: This filter traps particles larger than 5 microns, such as sand, sludge, rust, and other suspended debris.
Activated Carbon Filter (ACF): This filter removes chemical impurities like chlorine, which is highly oxidizing and can damage the membrane if not filtered out. Activated carbon is highly porous, with a large specific surface area, allowing it to adsorb various chemicals and improve water quality.
Semi-Permeable Membrane: The core component of the RO system, the membrane acts as a selective barrier, allowing water molecules to pass through while retaining suspended solids and other contaminants.

An RO system is not designed to remove limescale from all household water. If the goal is to eliminate limescale to protect appliances, a water softener is needed instead of an RO system.

Five Stages of Filtration in Reverse Osmosis:

Sediment Filter: The first stage captures larger particles like sand and rust, preventing them from reaching the finer filters.
Activated Carbon Filter: This filter removes chlorine, odors, flavors, and organic contaminants, resulting in better-tasting water.
Activated Carbon CTO Combination Filter: A more thorough filtration stage that removes chlorine, pesticides, and various harmful organic impurities through multiple chambers and channels.
Semi-Permeable Membrane: This membrane removes up to 97% of dissolved substances, including microorganisms, heavy metals, and chemical residues.
GAC Post-Filter: The final stage uses granulated activated carbon to ensure the water has all the desired qualities of drinking water.

Working Of Domestic Ro Plant

Reverse osmosis (RO) is an effective water purification system that provides mineral water directly at home through a filtration device that reduces pollutants in tap water. These systems are compact and typically installed under the sink, with a separate faucet to dispense purified water.

Understanding the Osmosis Process

Osmosis is a natural physical process where water moves through a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration until equilibrium is reached.

Reverse Osmosis works by applying high pressure to the side with the highest concentration of impurities and salts. This pressure forces water through the membrane, while microorganisms, viruses, and chemical contaminants are blocked. The result is high-quality drinking water that meets safety standards.

Efficiency of Reverse Osmosis Systems

Reverse osmosis filtration systems are effective at removing between 93% and 97% of contaminants, though not all pollutants are eliminated to the same extent. The system can remove a wide range of chemicals, viruses, microorganisms, and other impurities, such as chlorides, sulfates, salts, calcium, boron, iron, and bicarbonates.

This is achieved through a multi-stage filtration process:

Micro-filter: Removes sediments down to 5 microns.
Activated Carbon Filter: Reduces chemicals and removes chlorine.
Phosphate Filter: Further reduces chemical contaminants.
RO Membrane: Removes any remaining small solid particles.

Maintenance of a Home RO System

Maintaining a reverse osmosis system involves periodically replacing the filters and membrane and disinfecting the unit and storage tank:

Filters and Post-Filters: Typically replaced annually.
Membrane: Generally replaced every three years.
Disinfection: Regular cleaning of the unit and storage tank is necessary to maintain water quality.

Benefits of Reverse Osmosis

RO systems are highly effective and widely used worldwide to provide high-quality drinking water. The membranes in RO systems are capable of removing viruses, microorganisms, and other contaminants, ensuring clean water for consumption.

How a Domestic/Light Commercial RO Plant Works

Pre-Filtration: Polypropylene fiber cartridge removes dust, rust, and suspended particles.
Block Activated Carbon Cartridge: Removes odors and chlorine.
Granular Activated Carbon Cartridge: Further removes odors and chlorine.
Pressure Booster Pump: Maintains adequate pressure (120/140 p.s.i.) for effective filtration.
RO Membrane: Removes colloids, suspended substances, organisms, heavy metals, dissolved solids, and bacteria, allowing only pure water to pass through.
Post-Activated Salts: Absorbs any peculiar smells from the pressure tank, enhancing the taste.
Storage Tank: Stores purified water, with capacities typically ranging from 3.2 to 11 gallons.

By utilizing a reverse osmosis system, households can enjoy high-quality drinking water that is free from harmful contaminants, providing significant health benefits.
