The Importance of RO Recovery
RO systems generate two principal streams:
Permeate: purified water
Reject/Concentrate: water containing a higher concentration of rejected dissolved substances
For example, an RO plant producing 1, 000 litres per hour of permeate may require a higher feed flow depending on its recovery percentage.
Recovery should be selected according to:
Feed-water TDS
Hardness
Silica
Temperature
Membrane type
Scaling potential
Pretreatment quality
Trying to maximize recovery without considering water chemistry can increase scaling and membrane fouling.
Therefore, Enviro designs should be based on actual raw-water analysis rather than capacity alone.
What Makes the Enviro Approach Different?
A reliable RO plant is not simply an RO membrane mounted inside a skid.
The complete system must work together.
Enviro can integrate:
Raw-water treatment
Chemical dosing
RO membrane technology
High-pressure pumping
Electrical control systems
Online monitoring
Storage
UV treatment
Ozone where required
Remineralization
Structured-water conditioning
Automatic flushing
CIP provisions
PLC/HMI automation
This allows the system to be configured for residential, commercial, institutional and industrial applications.
Structured Water After RO Purification
RO water is generally low in dissolved mineral content compared with the original feed water.
For some drinking-water applications, the purified water may therefore undergo controlled post-treatment.
Depending on the design, this may include:
Remineralization
A remineralization stage can add selected minerals back into the water to achieve the desired taste and mineral profile.
pH Conditioning
The pH of RO permeate can differ from the feed water. Post-treatment can be incorporated where controlled pH is required.
UV Disinfection
UV can provide an additional microbial-control barrier without adding chemicals to the water.
Activated Carbon Polishing
Post-carbon filtration may be used where taste and odour polishing is required.
Structured-Water Conditioning
Where the customer specifically requires a structured-water configuration, additional physical conditioning equipment can be integrated into the purified-water line.
The exact technology should be selected according to the application and measurable water-quality requirements.
Structured Water RO Plant for Homes
Modern homes may receive water from several sources, including:
Municipal water
Borewell water
Tanker water
Mixed water sources
Each source can have different characteristics.
A residential Enviro RO system can therefore be designed according to the household's water test.
A typical system may include:
Raw Water → Sediment Filter → Carbon Filter → RO → Remineralization → UV → Storage → Drinking Water
The configuration can be adjusted depending on TDS, hardness, chlorine and microbiological requirements.
Structured RO Plant for Apartments
Large residential buildings have different requirements from individual houses.
Apartment complexes may need:
Centralized RO
Multiple storage tanks
High-flow pumps
Automatic level control
Distribution pumps
UV or ozone treatment
Online TDS monitoring
Flow measurement
Automated flushing
The RO capacity should be selected based on actual daily drinking-water demand rather than simply the number of residents.
For example, an apartment complex may use a centralized RO plant to supply drinking water to a dedicated purified-water network.
Commercial Applications
Enviro Structured Water RO Plants can also be configured for:
Hotels
Restaurants
Cafés
Offices
Schools
Colleges
Hospitals
Resorts
Shopping centres
Commercial buildings
Food-processing facilities
Commercial installations typically require greater attention to operating hours, storage capacity, redundancy and maintenance access.
For a hotel, for example, the RO plant may be connected to a treated-water storage tank from which water is distributed to kitchens and drinking-water points.
Industrial Applications
Industrial water requirements vary considerably.
Some processes require low-TDS water, while others require specific conductivity, hardness or contaminant limits.
Enviro RO systems can be designed as part of larger treatment systems involving:
Raw Water → Pretreatment → RO → DM/EDI → UV → Final Storage
Potential applications include:
Manufacturing
Electronics
Pharmaceutical support systems
Laboratories
Food processing
Boiler feed pretreatment
Process-water treatment
Cooling-water applications
Chemical industries
