Reverse Osmosis (RO) in Water Purification

Reverse Osmosis (RO) in Water Purification

Purified and mineral water are common water for drinking. However, the two forms are manufactured in different distinct processes before it is packed in bottles using the water filling machine. For instance, purified water is generated through the reverse osmosis process while the mineral water is mainly through the ultrafiltration process. You can as well generate both pure and mineral water through the RO process. The purpose of general water treatment is to remove the contaminants from the raw water and make it pure enough for drinking and other purposes. The most common contaminants are bacteria, suspended solids, fungi, minerals such as iron, sulfur, manganese, algae, colloids, and pyrogens.

Purpose of reverse osmosis

  • To prevent suspended particles and colloidal material from plugging
  •  To prevent membrane fouling
  •  Prevention of microbial fouling
  •  Prevention of organic fouling
  •  Prevention of oxidation
  •  Maintenance of stability in ultrafiltration plant
  •  To perform auto and manual washing
  • To manual wash with treatment
  • To auto stop, high water levels and auto start low water levels

RO Process

This process begins by removal of suspended particles and impurities such as micelle in quartz sand filter. Then there is a softener and an active carbon filter where an organic substance, chromo, chlorine, and the odor is gotten rid of. This filter usually has the consummate pretreatment system that allows the RO system to be standby for long.

The organic substance, salt, heat source, bacteria, and other impurities are normally removed in a reverse osmosis system. Also, with this process, the ration of salt-doffed will be 97-99 percent. Depending on the nature of machines, this process can be manual or automatic. The automatic process usually adopts the pressure and water sensor. The system will be fully automatic when adjusted to auto mode and is easy to operate.

In the RO process, the untreated and treated water are separated by a membrane. There is an osmotic pressure that enables the treated water to untreated water. If pressure is added to the untreated water the osmotic pressure increases forcing the untreated water to move in the other direction. If water has a lot of suspended particles and solutes, it cannot move through the membrane and will get drained out.

RO Maintenance

To protect the RO membrane, you must ensure that the water is pretreated first before it comes to the system. You can monitor this process of purification using the conductivity meter. You also have to clean regularly the filters, steel pump, valves, disinfectant tanks, and other RO components.

Factors to consider when buying water filling machine

Factors to consider when buying water filling machine

For individuals who want to purchase a water filling machine, get the best one that fits your production line can be tiresome and a bit challenging. There are various things you have to take into consideration including the nature of power conveyors, fillers, labelers, and capping machine. This guide will give the various aspects to factor in and an insight into the entire water filling process.

Water filling machine is designed in such a way that the whole process is integrated and continuous. It begins by cleaning the bottles, filling them, capping and finally labeling them before they are distributed. Although many machines can suit you, there is always one machine that will give you the best solution. Here are the various aspects that will enable you to find the ideal water filling machine:

The nature of your bottles

Some bottles require more sophisticated machines than others. Before getting your water filling machine ensure you know the type of containers that you will be using so that you can choose the right one. Some machines have been designed to offer specific packaging options and are limited to a number of adjustments. Some also have been designed to handle various bottle sizes while others are fixed to hand specific type only.

The production rate

One of the key aspects of a water filling machine is the number of bottles it can pack in an hour. For instance, if you require 2500 water bottles every hour, then you will have to purchase a 2000-3000 water filling machine. However, if you need a machine for high production, then you go for water filling machine that handles 12000 to 15000 bottles in every hour. This machine usually has many heads for rinsing, filling and packing compared to the other ones.

Production cost

Some machines are not good for small-scale production. Some require high costs for running that include power consumption rate and maintenance. You should always ensure that the machine you incorporate has a positive impact on the industry. Some are semi-automatic while others are fully automatic making production process much easier. Depending on your product rate, ensure that the machine you incorporate will add value to the output.

Integration process

Some water filling machines need some operators to move bottles from one stage to the other. However, others are semi-automatic and automatic where the whole bottling process has been integrated into one. With fully automatic machines, the process of cleaning, filling, and capping is integral and continuous allowing you to package more bottles within a short period.
