Residential RO Plant for Home
The correct home RO system depends on your actual water quality, not a standard product list. Aqua Prima tests your source water before recommending any residential system.
Key question before buying a home RO: What is your bore or supply water TDS, hardness and microbiological status? A water test takes little time and determines whether RO is the right treatment for your specific water — and if so, which system.
Do You Need a Home RO Plant?
| Your Water Situation |
Likely Consideration |
| High TDS bore water (above 500 ppm) |
RO is commonly used to reduce dissolved solids |
| Hard water (scaling on taps and appliances) |
Softening pretreatment may be needed alongside RO |
| Sediment or turbidity issue |
Sediment prefiltration required before membrane |
| Microbiological concern |
RO removes bacteria; UV post-treatment often added |
| Good municipal supply, taste concern only |
Carbon filtration may be sufficient; test first |
What a Complete Residential Installation Includes
- Source water test (TDS, hardness, pH, turbidity)
- System sizing based on household daily demand

- Activated carbon prefilter
- High-rejection RO membrane
- Post-carbon polishing filter
- Pressure storage tank (4 gallon or larger)
- Dedicated drinking-water faucet
- TDS meter for ongoing monitoring
- Installation and commissioning
- Output TDS verification before handover

FAQs
Is a 5-stage or 7-stage RO better for Lahore bore water?
For Lahore bore water with typically high TDS and hardness, adequate pretreatment matters more than the number of stages. At minimum, sediment and carbon prefiltration should precede the membrane, and UV is often recommended given microbiological concerns in some localities. Aqua Prima sizes the system based on the actual water test, not stage count.
How do I know if my home RO membrane needs replacement?
The most reliable indicator is rising permeate TDS over time. A TDS meter allows regular monitoring. When permeate TDS increases significantly from your post-installation baseline despite good prefilter maintenance, membrane replacement should be considered.
Can I get the RO serviced after installation?
Yes. Aqua Prima provides ongoing maintenance and filter replacement services.
