How to determine the water production capacity of a single-stage reverse osmosis water treatment equipment?

1

Single stage reverse osmosis equipment

Single stage reverse osmosis equipment is a process where raw water and tap water are treated by a pre-treatment system, and then pressurized by a primary high-pressure pump to enter the RO membrane for treatment, resulting in purified water production. The simple way to determine is that there is only one high-pressure pump on the device. Understanding this point, let's take a look at how to determine the water production capacity of the equipment.

Understanding the determinants of water production: model and number of RO membranes

When we go to a water treatment equipment company to purchase water treatment equipment, they will ask us what size of water treatment equipment we need, that is, what amount of water production equipment we need. We need to first understand that the water production of reverse osmosis water treatment equipment is determined by the RO membrane.

There are two types of RO membranes, 4-inch and 8-inch, usually installed inside the RO membrane shell. There are 4-inch small membrane shells and 8-inch large membrane shells, mainly made of fiberglass and stainless steel, with one shell and one core and one shell and two cores (two RO membranes in one membrane shell).

Calculate water production based on the number of membrane shells

Calculate the water production by counting the membrane shell. To know the water production of a single-stage reverse osmosis equipment, we first need to look at whether it is a large membrane or a small membrane, and then count how many RO membrane shells there are. By looking at the length, we can determine whether the RO membrane is one shell and one core or one shell and two cores, and calculate the water production of the equipment.

Ordinary 4-inch RO film

The water yield of a commercial membrane with a single diameter of 4 inches is 0.25T/H. What we usually see is the membrane shell of the equipment. We can request the water treatment equipment manufacturer to disassemble and assemble the RO membrane on site. The water production capacity of a 1-ton single-stage reverse osmosis equipment is 0.25T/H/unit * 4 units=1T/H. You can use a shell by core membrane shell.

Ordinary 8-inch RO film

Commercial membrane - a single 8-inch diameter membrane has a water production capacity of 1T/H. When the equipment we need produces a large amount of water, the manufacturer will provide us with an 8-inch large film. This not only produces a large amount of water, but also reduces the number of films. The equipment has a compact structure and a beautiful appearance.

The water production capacity of a 6-ton single-stage reverse osmosis equipment is 1T/H/tube * 6 tubes. A RO membrane shell with one shell, two cores, and three tubes is sufficient.

Summary

By looking at the numbers two, three, and four calculations, we can determine the water production of a single-stage reverse osmosis equipment.
