Frequently Asked Questions

What is the difference between RO and deionization?

Reverse osmosis uses a semi-permeable membrane to remove contaminants, while deionization uses ion-exchange resins to remove charged ions. RO is ideal for general purification; DI produces ultra-pure water for sensitive applications.

Can your systems treat seawater?

Yes, our Sea Water Desalination Systems (SWRO) are specifically designed to convert seawater into potable water using high-pressure reverse osmosis technology.

Do you offer custom solutions?

Yes, we provide tailored water treatment systems based on water source, flow rate, and quality requirements. Contact us with your specifications.

What maintenance is required?

Regular filter changes, membrane cleaning, and system inspections are recommended. Our team provides detailed maintenance guides and support.

Is installation support available?

Yes, we offer technical guidance and remote support for installation. On-site services may be arranged depending on location.
