Comparison between Reverse Osmosis and Ultrafiltration Process

Comparison between Reverse Osmosis and Ultrafiltration Process

Drinking clean and pure water is good for your health. However, before this water is packed using a water filling machine it has to go through a series of processes for purification. These processes vary depending on the nature of the water you want to get. For instance, for mineral water, ultrafiltration is usually the ideal process, unlike the purified water that has to go through reverse osmosis.

In most cases, raw water contains minerals and harmful substance such as bacteria, chemicals, pesticides, pyrogens, and other contaminants. When removing these substances, water has to go through a purification process that includes the ultraviolet rays, reverse osmosis and ultrafiltration purification. Here is the comparison between the ultrafiltration and reverse osmosis.

Reverse Osmosis

In the Reverse Osmosis or RO, water filtration system requires power to operate and usually removes all the dissolved particles that are available in the water. The RO Water Purification system additionally offers prefiltration when you need to purify the contaminated water, and this purifier expels all the germs and bacteria.  Power, in this case, is also needed to boost pressure for osmosis to happen.

Reverse Osmosis usually requires the availability of a large amount of water; If you input 3 Liters of Water into an RO system, you will probably generate one liter of purified water and two liters of wasted water. However, you can make use of the unused water for wiping the floor, cleaning the house and other home remedies.

Most of the domestic RO systems that are accessible online are not fit for desalination which implies they can’t be used to distill the saline water into purified water. Additionally, unbranded RO water systems don’t hold natural minerals effectively.

There are a considerable number of RO Water systems available on the online, and you can get an ideal RO system that is fit for not just expelling the toxic salts and hard metals but removes the minerals that present in the raw water.


The Ultrafiltration, which is also named UF, is another water purification framework that works without power and totally removes and kills the virus, bacteria and different microorganisms present in the water. Unlike UV Water purification system, the UF purifier expels every one of the germs and dead microscopic organisms from the water after it kills them.

The UF Water purifier doesn’t require power since it only requires pressure unto which tap channeled through pipes haves. However, in this case, contaminants such as dissolved salts and minerals are not removed. This method is ideal for making mineral water, unlike the RO that is ideal for pure water.

How efficient are water filling machines

How efficient are water filling machines

When it comes to production bottle water, water filling machine usually come in handy. These machines are responsible for rinsing, filling and finally capping PET bottles. They usually come in various sizes different features. Depending on your production line you should choose the one that best suits your preferences.

The efficiency of water filling machines varies from one to another. There are some that have been automated and integrated into one process. This is where rinsing, filling, and capping are done in one single process. For instance, there is a water machine that can pack and prepare 2000-3000 bottles per hour. This type of machine is only meant to pack mineral water, purified water, and non-carbonated drinks only. The rinsing chamber consists of 8 valves for rinsing, eight heads for filling and three heads for capping. With this features in place, more than 200 bottles can be achieved making it more efficient and time-saving.

Small bottling plants

For small plants, water bottling machines are designed without the inline system. They are made of compact construction that makes them utilize less space while using the monologue modules. They also have a quick changeover, PLC control and motors that are synchronized for easy maintenance. The operator has to load bottles in an air conveyor where the machine rinse and then fills water before capping them. A small 2000-3000 bottles water filling machine is fully automated and requires less maintenance.

Medium bottling plants

Secondly, there water filling machine that handles 4000-5000 bottles in every hour. These machines are fully automatic and pack 200ml to 1500ml PET bottles. They handle mineral water, purified and non-carbonated. These machines usually have 14 valves for rinsing, 14 heads for filling and five heads for assembling. The rinsing, filling plus the assembling process is integrated and fully synchronized making it ideal for small-medium water bottling companies.

 Large Bottling plants

Then there are water filling machines that handle 6000 to 7000 bottles, 8000 to 10000 bottles, 10000 to 12000 bottles and finally 12000 to 15000 bottles. These large have 32 nozzles for rinsing, 32 heads for rinsing and eight caps for capping. It is ideal for large water bottling plants as it has an effective and reliable workhorse.

Rinsing station

At the rinsing station, the PET bottles enter continuous while they are inverted to allow proper rinsing.

Filling station

At the filling station, the rinsed bottles are filled with high-speed filler. This process is consistent and precise to allow the same amount of water to be packed in each bottle.

Capping station

At the capping station, there is non-stop movement of bottles allowing capping to be done continuously. At this station, there is raping capping system that provides enough torque to tighten each cap effectively.

Advantages Of Capital Intensive Compared To Labour Intensive Production In Reference To Water Filling Machine

Advantages Of Capital Intensive Compared To Labour Intensive Production In Reference To Water Filling Machine

With the world moving away from the olden ways and embracing the use of technology especially in making work more accurate and easier, automation in the packaging process provides benefits to the packaging person/company.

The following are the reasons why we should embrace the use of water filling machine 

Ease in use

All water filling machines come with a guide and an easy to use operator interface. The touchscreen at the interface allows the operator to customize it by entering various times and amounts necessary to complete a cycle. This ease of use will be cumbersome if one is to physically several bottles of water in numerous amounts.

Diversity in use

A water filling machine can be used to package different beverages/products to different bottles. Most of the water filling machines require simple adjustments to change from one bottle type to another or one product to another. This would not be achieved easily with manual filling especially where product viscosity and bottle sizes have great variations.


Once the market demand reaches a certain high level, the production demand is proportionally affected, and thus, the ability of the water filling machine to adjust to such changes makes it advantageous over the manual filling of water bottles. Except for wear and tear, machines do not get tired, unlike human beings. Hence the use of water filling machine facilitates constant, flexible and faster running of services.

Reliable Fills

The use of water filling machine promotes consistency and reliability in the filling process. The producer/ company will not have to look for other ways of getting to know the volume of the fill or using other criteria. The water filling machine ensures that each cycle is completed in the same manner. Consistency and reliability that would be hard to achieve by hand filling the bottles can easily be achieved with this machine.

Room for change

Most water filling machines are manufactured with future growth potential in mind. There is always room for simple additions to water filling machines such as other fill heads that will allow the equipment to grow with the business. This may pose a challenge, especially with labor-intensive production, as usual; the man is resistant or slow to change.

Cheap cost of production

Acquisition of a water filling machine is a one-off thing that when the machine is bought, it will require a few people to control it thus reducing the cost of production, unlike manual filling whereby the cost of production will increase with the increase in the market demand.

Tips for Freezing Food with a Vacuum Sealer

Tips for Freezing Food with a Vacuum Sealer

If you have a problem with food going bad often, then a vacuum sealer machine is your solution. These are machines that can help you get to preserve all types of food including the perishable foods. Freezing foods with a vacuum cleaner is the best way to extend your food’s shelf life. But how do you it correctly? Here are tips on how to freeze food with a vacuum packing machine like a pro:


One of biggest mistakes that people make is wrong food preservation of food using a vacuum packaging machine. To most people, they just put food from the market directly into the bag and vacuum seal them. That is wrong. It is one of the reasons why some foods such as fruits and vegetable may get squashed when vacuum sealed. Pre-freezing is one of the best ways to get the most out of the vacuumed foods. It helps to get rid of air bubbles that usually squashes food. What you need is first to freeze the food and them vacuum seal it. Pre-frozen foods have a longer shelf life compared to those vacuum sealed directly.

Freezing Cooked and Uncooked food

This is another area that most people fail when it comes to the use of a vacuum sealer. These two foods should be treated differently, and that’s where people get it wrong. For cooked dishes such as soups and sauces can be vacuum sealed and they reheat really well while preparing them some days later. But others such as vegetables may not need to be cooked but can be preserved in their raw form. For the cooked dishes such as ground turkey, you can cook and vacuum seal them when you have time to spare. This tip works well in hotels where the time to numerous orders limited and thus precooking dishes is the only way out.

Portion It Out Properly

The preservation effectiveness of a vacuum sealer depends on two things- the size of the paper and the portion. Make food portions depending on the size of the paper bag. The mistake some people make is thinking that they can put a lot of food in a bag and vacuum it. That will definitely flop. Make sure that you’ve made the right portions to ensure that the food as enough space. Make sure that you have the right portion depending on the kind of papers that you’ve. However, the size of the paper should be determined by the size of your vacuum packing machine.

Always label Packages

Another mistake that people make is failing to label to label the packages after vacuum sealing. This is one of the key things that you need to consider for proper food preservation, especially if you are vacuuming a large number of foods. Make sure that you’ve labelled all the foods to ensure that you don’t forget and mix up everything. Write the name of the food or dish so that even if another person visit your kitchen, then make a meal using with minimal efforts.  If the food is expected to last for months, then you must consider the kind of ink that will not fade away with time.

Buy Special Bags

The choice of the bag is crucial when it comes to vacuum sealing food. One big mistake that people make is buying any bag that they find in the market with researching in products ability to keep air and moisture entirely out. It is recommended that you buy paper bags from the original manufacturer of the machine since they have the quality needed to keep the food safe for long. But there are generic or third-party plastic bags that offers high-quality features as well. But you need to do a little bit more research before spending on generics.

Don’t Reuse Bags

Last but not the least is to avoid reusing plastic paper bags. It is a practice that some people have especially while trying to save on the cost of the paper bags. While this may work for some, it is not recommended since it can lead to food damage. Some of the vacuumed food such as raw meat could have left bacterial which will destroy food.

These are vital tips that you should consider when it comes to freezing food with a vacuum sealer. Just follow them, and you will never have a problem with vacuum sealed food going bad.
