A bag filter is a filter that purifies water. A bag filter is an affordable method to filter water quickly. All the sizes of bag filters always depend upon individual usage purposes. They are best for reducing the all impurities like sand, dirt, silt and other sediments in the water.
Usage places of bag filters:
The following are the usage places of bag filters:
Effluent Treatment Plants,
Sewage Treatment Plants,
Municipal Water Supply,
Industries, and many More
Bag filters for water treatment:
Bag filter treatment contains one or more bag filters and they are placed in a bag filter housing to remove all the suspended solids, impure particles from feed water. Often Bag filters used in this treatment may change based on the industry and their usage. This filtration process costs low compared to other filtration processes and filters a large amount of water quickly.
Bag filter treatment is the perfect way to remove all the impure particles, suspended solids in huge volumes of water, especially at a very high flow rate. When we compare the bag filtration process with some other filtration processes, this bag water filter treatment is both best and cost-effective, especially for very high volumes of water.
Benefits of this bag water filter treatment:
The following are the benefits of bag water filter treatment:
- It can filter huge volumes of water along with high flow rates. It can easily and fastly filter more than 100M3 of water per hour based on both filter and housing dependent.
- Bag filters have a great capacity to store and hold all the dirt particles.
- Bag filters have a long span; also, you can reuse them by washing them whenever they fill fully.
- Even changing bag filters is very less than cartridge filters.
- Bag filters are very easy to install and easy to replace
- They even cost very low and work more effectively compared to cartridge filters.
- Easy maintenance.
The life span of bag filters:
The life span of bag filters is very long. You need to change bag filters rarely compared to a cartridge filter, and you can easily remove and wash them whenever the bag storage is full.
I hope this article gives you clear information regarding bag filters. Always better to choose bag filters than cartridge filters as they are less costly and work very effectively. Also saves your penny and time compared to cartridges
In this article, you know about the best manufacturer and Design Considerations for RO Plant by the Sahara industry. We also discussed clear things about RO like 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. to know clearly about it; click on our previous blog, which is very useful and very important to know.
Sahara industry is one of the topmost industries in India. It is the best manufacture of RO plant and gives you best quality services with reasonable prices. Sahara industry is a single roof for all products related to water treatment.
Design Considerations for RO Plant by Sahara industry:
Sahara industry RO plants mainly work on the method of crossflow Filtration. This filtration method takes feed water and uses a percentage of it to wash or reject a stream. It removes all the containment solids in the filtration process. The product flow of this RO plant depends upon temperature and pressure. System recovery is very limited based on characteristics of that feed water, and it is controlled by usage of recycle stream.
By reading the above information, you can clearly understand that the Sahara industry is the best place to get RO plants.
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.
Reverse osmosis is a process to remove all contaminants from feed water by applying external pressure forces on a semipermeable membrane. In this process, the feed water flows from the high concentrated side of the RO membrane to the low concentrated side (fewer contaminants) through a semipermeable membrane to give fresh and clean drinking water. The concentrated water molecules left over is known as waste or brine.
A semipermeable membrane contains very small pores that can block all the contaminants and only allow water molecules to flow through it. In the osmosis process, less concentrated water moves towards high concentrated water through the membrane to maintain equilibrium on both sides. But the reverse osmosis process blocks all the highly concentrated contaminants from entering into the less concentrated side through the membrane. Suppose, for example, when pressure is applied to the volume of sugar water during this reverse osmosis, the sugar molecule is left on the high concentrated side, and clean water flows through the low concentrated side.
Working principle of Reverse osmosis:
RO process working principle is opposite to the osmosis process. Osmosis occurs naturally, but here in the RO process, we need to apply some external pressure on the high concentred contaminant side to pass water molecules into the low concentrated side to produce fresh and clean water.
What can a reverse osmosis system remove?
A reverse osmosis process can remove all dissolved solids like fluoride and arsenic through the RO membrane. It removes fluoride, salts, chlorine, pesticides and bad taste, odours, and dirt too.
Benefits of the reverse osmosis process:
- The following are the benefits of the reverse osmosis process:
- RO process removes all dissolved solids from water.
- This process also removes the bad tastes and odour of the water.
- It gives you clean and fresh water.
- You can easily install them and maintain them too.
The life span of reverse osmosis systems:
Reverse osmosis systems can at least last for 10 and 15 years. So absolutely, the system has a long lifespan; only the RO membrane and filters need to be replaced periodically. Both the pre filters and post-filters need to be changed every six months to 1 year. Depending on the water conditions, the RO membrane needs to be replaced every 2-4 years.
Applications of reverse osmosis:
The following are the reverse osmosis applications :
- Food and beverages,
- Pharmaceuticals industry
- Diary industries
- Coaching institutes
- Bus stands
The reverse osmosis process produces clean water and also gives you freshwater by removing harmful dissolved solids.
