How Is Ozonator Used In Water Filtration?
SAHARA INDUSTRY has a wide range of Ozonators starts from 0.5 gram ozonator to 200 grams ozonators. We supplied number of ozonators to swimming pools, textile industries, pharmaceuticals and mineral water plants.
Ozone has a greater disinfection effectiveness against bacteria and viruses compared to chlorination. In addition, the oxidizing properties can also reduce the concentration of iron, manganese, sulfur and reduce or eliminate taste and odor problems.
Ozone oxides the iron, manganese, and sulfur in the water to form insoluble metal oxides or elemental sulfur. These insoluble particles are then removed by post-filtration. Organic particles and chemicals will be eliminated through either coagulation or chemical oxidation. Ozone is unstable, and it will degrade over a time frame ranging from a few seconds to 30 minutes. The rate of degradation is a function of water chemistry, pH and water temperature.
Ozonation Process:
The formation of oxygen into ozone occurs with the use of energy. This process is carried out by an electric discharge field as in the CD-type ozone generators (corona discharge simulation of the lightning), or by ultraviolet radiation as in UV-type ozone generators (simulation of the ultraviolet rays from the sun). In addition to these commercial methods, ozone may also be made through electrolytic and chemical reactions. In general, an ozonation system includes passing dry, clean air through a high voltage electric discharge, i.e., corona discharge, which creates and ozone concentration of approximately 1% or 10,000 mg/L. In treating small quantities of waste, the UV ozonators are the most common, while large-scale systems use either corona discharge or other bulk ozone-producing methods.
The raw water is then passed through a venturi throat which creates a vacuum and pulls the ozone gas into the water or the air is then bubbled up through the water being treated. Since the ozone will react with metals to create insoluble metal oxides, post filtration is required
Ozone Applications:
- Ozone generator for RO plants
- Ozone generator for Aquarium
- Ozone generator for Swimming pool use
- Ozone generator for pharmaceutical use
- Ozone generator for Mineral water plants
- Ozone generator for Textiles use

A few important things to know about FRP Pressure vessels
FRP (Fibreglass Reinforced Plastic) is an updated composite material used for chemical plants appliances and equipment namely vessels and tanks. FRP tanks and vessels have a number of useful applications including both industrial and commercial water treatment system. FRP tanks or vessels are durable, lightweight, flexible, high strength, corrosion resistant and less expensive. And thus such vessels are often considered as the true alternative to SS vessels.
What are the Features and benefits of FRP vessels and tanks:
- Since they don’t rust, there is no need for reclading or painting.
- FRP vessels have only a very few issues related to stress, heat, conductivity as well as weather conditions.
- They have higher and better corrosion resistance capacity in comparison to their metal counterparts.
- FRP tanks and vessels are super light in weight. They are just 2/3rd the weight of aluminum while only 1/4th of steel. And thus FRP equipment’s can be better handled.
- FRP items are less expensive than metal alternatives; like they are almost half the price of steel. FRP lasts at least 5 to 10 times longer than stainless steel even in extreme corrosive environments.
- FRP equipment is more skid resistant than the metal ones.
- FRP vessels are now equipped with better resin treatment related to impact, heat and crack. And this obviously encourages its extensive use versus metal substitutes by the topnotch FRP Vessels / Tank Manufacturer.
- They are highly customizable in terms of design.
- FRP is non-conductive of electricity and thus there is no risk of shorting out electrical equipment.
- Addition of brominated materials makes FRP vessels ignition resistant.
- FRP is an efficient insulating material featuring good thermal expansion property.
- FRP vessels can be well heat traced from the bottom of the same.
- It hasn’t any flammability hassle while welding.
- It doesn’t leave any trace metal contamination in shampoos or antiperspirants.
- Its adhesive feature and elongation of resin help absorbing equipment vibrations.
Why is FRP a preferred choice for manufacturing tanks and vessels?
FRP is a widely accepted and widely used material typically used for making vessels and tanks to be used in chemical plants as well as water treatment systems. The key construction is done by means of filament winding. FRP is essentially corrosion resistant. It doesn’t develop corrosion even while exposed to liquid. Moreover, it can effectively withstand hydrostatic forces and strong tensile as well. It is often better and stronger than stainless steel. And thus FRP is often chosen for manufacturing water vessels and storage tanks.
How do FRP tanks and vessels help in water treatment ?
As already mentioned, FRP is immuned to liquids including water as well as harsh chemicals. Thus the any leading FRP Pressure Vessel Manufacturer prefers FRP for using in water treatment plants. FRP is leak-proof and thus it keeps the flow of water easy and lucid. Moreover, it is flexible and thus can be given any shape (vertical or horizontal.) and size (big or small).

Features of FRP Membrane Pressure Vessels:
The following are the features of FRP Membrane Pressure Vessels:
- All these are approved designs by only USDA for clean filtration of water.
- The Design parameters of FRP Membrane Housings are as per ASME standards.
- Available in different sizes of diameters and lengths
- You can safely consume clean and fresh water.
- It can be available in both high and low pressures of PSI units
- Low operational cost.
Evaluation of FRP Membrane housing:
During the 1990s, in place of FRP membrane, everyone used stainless steel, mild steel. After that, they observed corrosion, rust, and less resistance power if the water contains chemicals during filtration.
Now FRP membrane Housings are used to replace stainless steel, mild steel as they are corrosion-free had the best mechanism strength and chemical resistance. It also contains operating pressure from 300to 1500 PSI.
Different types of FRP membrane housing models:
There are two types of FRP membrane housing models. They are:
- End port
- Side port
End port:
The end port FRP membrane housing model is used for a plant with less than five membranes. So if we send feed water in one direction, wastage, purified water will come from the end side.
Side port:
To make an easy pipe, you need to prefer the side port model as the end port model is complex for large membranes. The side-port membrane housing model is used for plants with more than five membranes. If we send water in one direction, wastage, purified water will come from opposite directions.
How to calculate a number of elements in FRP membrane:
Follow the below procedure to calculate a number of elements in FRP membrane housing:
One element length= 40 inches.
Suppose if we consider 8 inches with five membranes:
The formula for calculating 8 inches with five membranes = 80 after (length (total membranes)).
(40(5)) = 200,
Then we need to place this 200 after 80.
= 80200
Therefore it 80200 model.
Suppose if you observe like 40240 model, then you think like this:
40 after (length (total membranes)
40 after (240)
40 after (40 inches (6 membranes)
Therefore it is 4 inches membrane housing with 6 membranes.

Characteristics and requirements of FRP membrane housing
Characteristics of FRP membrane housing made it special, and even small scale to large scale industries prefer FRP membrane housing for liquid treatment only because of its characteristics and performance.
In this article, We will explain about the characteristics, performance and requirements of FRP membrane housing.
Characteristics of FRP membrane housings:
The following are the characteristics of FRP membrane housings:
Excellent and reliable internal quality:
The FRP membrane housing is manufactured by a controlled CNC Filament winding unit with the best performance processing equipment. The primary materials are epoxy resin and fibreglass. This unique process is used to prepare the FRP membrane housing for temperature, pressure, and corrosion resistance. Its advantages are compared to any ordinary steel, plastic, and other materials that can’t match.
Good insulation performance:
The thermal conductivity of every FRP membrane housing is usually 0.15 – 1.36 W (m.k), only about 1/200 at room temperature, these thermal insulation properties are unmatched by all metal materials. This property greatly benefits the reverse osmosis membrane in the membrane housing and affects the membrane’s external temperature.
Best corrosion resistance:
The combination of both glass fiber and epoxy resin primarily acts as a natural anti-corrosion product. The inner surface is also very smooth, and the coating has the best stability to solvents like acid, alkali, salt, and oil with low concentrations. The seawater, microorganisms, etc. Which are entering the FRP Membrane housing are very effectively smothered so that there is no corrosion for Life term usage.
Structural design:
The design of the barrel, head, and groove of the FRP membrane housing is separated, and the calculation details are constantly optimized to make sure the structure’s safety. The concentrated water side opening is constantly optimized to meet all the necessary safety pressure for opening, especially the head’s four side ports, and improves variability during installation.
Component reliability:
The endplate is an important accessory of FRP membrane housings and has the best strength, best pressure resistance power, and high-pressure impact resistance. The seal is professionally designed as a “V+X” ring with an O-shaped endplate seal to ensure that it never leaks under any low or high-Pressure ranges. The side opening seal design combined with L-shaped drum round pads ensure the best sealing effect of the side opening mouth under that angular offset. The side opening is secured with a lifting-up affixing to make it more flexible.
Temperature maintenance:
The FRP membrane housing can mainly be used continuously for filter purposes for a long time, but to make sure long-term and best use of the FRP membrane housing strictly comply only with the temperature in between (-7c to 49c) that the product can withstand. Therefore, it is not safe to exceed this (-7c to 49c) temperature range and work under these conditions. Also, read the instructions pressure range for your FRP Membrane Housing.
Performance of premium FRP membrane housing:
The following are some of the performances of premium FRP membrane housing:
The internal structure performance is perfect, safe, trusted, and designed with good quality materials.
The matching components provide excellent sealing pressure performance.
