Round Disc RO (RDRO) – FAQ
1. What is Round Disc RO (RDRO) Technology?
Round Disc RO (RDRO) (Reverse Osmosis) technology utilizes a series of circular disc-shaped membranes arranged in a stack. Water flows through these discs, and impurities, Salts are filtered out, resulting in purified water.
2.How does Round Disc RO (RDRO) differ from Spiral RO?
Spiral RO employs spiral-wound membranes, while Round Disc RO (RDRO) uses flat, disc-shaped membranes. This fundamental difference in design leads to distinct advantages in certain applications.
3. What are the key advantages of Round Disc RO (RDRO) over Spiral RO?
Round Disc RO (RDRO) often excels in handling high-solids, high COD, high SDI content waste water, offers higher flux rates, and generally requires less maintenance compared to Spiral RO.
4. How does Round Disc RO (RDRO) handle high-solids, high COD content effluent?
The unique design of RDR0™ system, the turbulence created due to flow pattern minimizes the fouling of membranes.
5.What are the typical recovery rates achieved with Round Disc RO (RDRO)?
High recovery of approx. 90 to 97% can be achieved based on the input water characteristics. high recovery rates up to 92%-97%, maximizing water utilization.
6.How does the modular design of Round Disc RO (RDRO) contribute to easier service and maintenance?
The modular design allows for easier access to individual DISC membranes for inspection, cleaning, and replacement, minimizing downtime and simplifying maintenance procedures.
7.How can I choose the right RO technology for my specific needs?
NIRTECH can help you assess your requirements and select the most suitable RO technology, whether it's Round Disc RO (RDRO) or Spiral RO.
