Reverse osmosis equipment
1、 Description of 0.25 t 0.5 T 1 T 2 T RO equipment industrial water purifier:
The reverse osmosis pure water equipment adopts different processes according to different source water quality. Generally, the conductivity of tap water treated by primary RO pure water equipment system is less than 10us / cm, and the conductivity of tap water treated by secondary RO system is less than 2us or even lower. Ultrapure water can be prepared by laying ion exchange equipment or EDI equipment behind RO system, and the conductivity can reach 18 megaohm (conductivity = 1 / resistivity).
2、 0.25 t 0.5 T 1 T 2 T RO equipment industrial pure water machine pretreatment Configuration Description:
1. Raw water tank (optional)
It is used to store raw water, buffer the impact of unstable water pressure in raw water pipe on water treatment system, and to precipitate large sediment particles and other precipitable substances in groundwater.
2. Coagulant addition
It is mainly used to remove the colloid of suspended matter with small particle size in water. Because these tiny particles will not settle under the action of gravity in water and are difficult to be removed in subsequent filters, it is necessary to coagulate the raw water. It is through adding coagulant in raw water to make it form larger flocs with suspended solids and colloids in water, and then remove them through multi-media filter. When the content of iron in raw water is less than 0.3mg/l and the content of suspended solids is less than 20mg / L, the pretreatment device can not be used. When the content of suspended solids and colloidal substances in water is relatively high, coagulant adding device is generally needed
3. Raw water pump
Constant system water supply pressure, stable water supply.
4. Multi media filter
The main purpose of the filter with multiple filter layers is to remove the sediment, rust, colloidal substances, suspended solids and other substances with particles above 20um in the raw water. Manual valve control or full-automatic controller can be used for backwashing, forward flushing and other operations. Ensure the water quality of the equipment and extend the service life of the equipment.
5. It can remove free chlorine and organic matter in water to protect reverse osmosis facilities
Free chlorine can oxidize and destroy the reverse osmosis membrane, and the residual chlorine in the influent is generally required to be less than 0.1ppm; organic matter is not only the bait of microorganisms, but also can dissolve the organic membrane material when it is concentrated to a certain extent, resulting in the degradation of membrane performance. There are many kinds of organic matters in water, and the harm of different organic matters to reverse osmosis membrane is also different. Therefore, in the design of reverse osmosis pretreatment system, if the total organic carbon (TOC) content in water exceeds 2mg / L, it generally needs to be treated. For the purification system with tap water as the water source, activated carbon adsorption is necessary, because the organic matter content in surface water is higher.
3、 Features of 0.25 t 0.5 T 1 T 2 T RO equipment industrial water purifier:
1. Reverse osmosis (RO) is a physical method of desalination and purification of saline water at room temperature. The desalination rate of ultra-thin composite membrane elements can be reduced by the pressure of water alone, and its energy consumption is lower in many treatment methods.
2. It does not need a large number of chemicals and acid, alkali regeneration treatment, no chemical waste liquid and waste acid, alkali discharge, no environmental pollution.
3. The reverse osmosis device can make water continuously, the system is simple, the operation is convenient, and the product water quality is stable.
4. The workload of operation maintenance and equipment maintenance is small.
5. The equipment covers less area and needs less space.
6. The imported reverse osmosis membrane has high desalination rate, long service life and low operation cost;
7. Automatic pretreatment system is adopted to realize unmanned operation;
8. Using imported booster pump, high efficiency, low noise, stable and reliable.
