Process of Reverse Osmosis|| Types of filters used in RO systems process||
In this article, you know about components of a reverse osmosis system, types of filters used in the RO process, the working process of RO, the objective of the RO process and different types of membranes used in the RO process. Also, we discussed basic details regarding RO to know about it; click on our previous blog, which may also be useful.
Components Of A REVERSE OSMOSIS SYSTEM:
The following are the components of a reverse osmosis system:
- Pressure Vessels & Membranes
- Membrane Housing
- TDS / Conductivity Meter
- Flow Meters
- Pressure Gauges
- Reverse Osmosis Skid
- Cartridge Filter
- High-Pressure Pump
- Control Panel
Types of filters used in RO systems process:
The RO membrane is the heart of the reverse osmosis system.
Every reverse osmosis water process includes filters like sediment, sand and activated carbon along with RO membrane. The filters used in this process are prefilters or post-filters, and they are based on the water passing through them before or after passing into the membrane.
The following are the types of filters used in the reverse osmosis process:
Sand / Sediment filter
Activated Carbon filter
Sand / Sediment filter: it reduces all the particles like dust, dirt and rust
Activated Carbon filter: it can reduce all VOCs(volatile organic compounds), chlorine, and some contaminants that give water a very bad taste or odour
Semipermeable membrane: it can remove up to 99.5% of TDS (total dissolved solids).
The objective of introduction RO process:
The main objective of introducing the RO process is to supply chemical free water, fresh and clean water.
The following steps are included in the RO process:
Step 1: first, the feedwater enters into the RO system.
Step 2: from the RO system, this feed water enters into the prefiltration process. Prefiltration contains filters like both carbon and sediment to remove all the sediments and chlorine that can completely damage the RO membrane.
Step 3: through high pressure pumps, the prefiltered feed water passes through the Semipermeable membrane where all the dissolved particles, even too tiny particles, are removed.
Step 4: After filtration, water flows into the storage tank, where it is done until needed. Then, a reverse osmosis process continues filtering the water until that storage tank is full and then off.
Step 5: Once you turn on the drinking water tap, water comes out from the storage tank through a post-filter to purify the drinking water before it gets to the tap.
Different types of membranes used in the Reverse Osmosis process:
The following are the different types of membranes used in the RO process:
- Spiral membrane
- Stainless steel membrane
- Plate& frame membranes
- Ceramic membranes.
- Tubular membranes
- Hollowfibre membrane
Prefer to this RO process to purify your water and to consume clean water every day.
