How to determine the water output of a single-stage reverse osmosis equipment?

1. Single stage reverse osmosis device

A single-stage reverse osmosis device is a device that pretreates raw water and tap water through a pre-treatment system, pressurizes them with a high-pressure pump, and enters the reverse osmosis membrane for treatment before production and purification. A simple way to determine is that there is only one high-pressure pump on the equipment. To understand this, let's take a look at how to determine the water production of the equipment.

2. Understanding the determinants of water production: the model and quantity of reverse osmosis membranes

When we go to a water treatment equipment company to purchase water treatment equipment, they will ask us how much water treatment equipment we need, that is, how much water production equipment we need. Firstly, it is important to understand that the water production of reverse osmosis water treatment equipment is determined by the reverse osmosis membrane.

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

3. Calculation of water volume for mold shell

Calculate the water production of the membrane shell. To understand the water production of single-stage reverse osmosis equipment, first look at whether it is a large membrane or a small membrane, then count the number of shells of the reverse osmosis membrane, determine whether the reverse osmosis membrane is a shell, core, shell, or two cores based on its length, and then calculate the water production of the equipment.

4. Ordinary 4-inch reverse osmosis membrane

The water production capacity of industrial film is 0.25t/h, generally seen in the equipment membrane shell. We can request the water treatment equipment manufacturer to disassemble and assemble the reverse osmosis membrane for us on site. The water production capacity of a ton level single-stage reverse osmosis device is 0.25t/h/pc * 4pcs=1t/h, and a modular shell with one shell and one core can be used.

5. Ordinary 8-inch reverse osmosis membrane

A single 8-inch diameter commercial membrane produces 1 ton/hour of water. When the equipment we need has a large water output, the manufacturer will use an 8-inch large film for us. This not only has a large water output, but also a small number of films. Moreover, the equipment has a compact structure and a beautiful appearance.

6T single stage reverse osmosis equipment has a production capacity of 1 t/h per unit * 6 units. The reverse osmosis membrane shell can have one shell and two cores with three membrane shells.

6. Summary

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