PLC Controlled 4T/h Reverse Osmosis Ro System for Industrial Drinking Water Treatment​

Description

Reverse osmosis equipment is the raw water through the fine filter, granular activated carbon filter, compressed activated carbon filter, etc., and then pressurized by the pump, the use of pore size of 1/10,000 μm (equivalent to the size of Escherichia coli 1/6,000, 1/300 of the virus) of the reverse osmosis membrane (RO membrane), so that a higher concentration of water into a very low concentration of water (that is, pure water) and a higher concentration of water, low concentration of water use, high concentration of water discharge or resource reuse, and at the same time, industrial pollutants, heavy metals, bacteria, viruses and other impurities mixed in the water are isolated, so as to achieve the required physical and chemical indicators for drinking and health standards, and thus to achieve a large number of drinking water and sanitation standards. The use of low concentration of water, high concentration of water discharge or resource reuse, at the same time will be industrial pollutants, heavy metals, bacteria, viruses and other large amounts of impurities mixed into the water are isolated, so as to achieve the drinking provisions of the physical and chemical indicators and hygiene standards, the output of the cleanest to the purest water, the human body to replenish high-quality water in a timely manner is a good choice. As RO reverse osmosis technology to produce water purity is currently mastered by mankind in the manufacture of drinking water in all the water technology in the higher, so people call this water machine for reverse osmosis water purification machine.

Parameter Table

Process flow

1. The first-stage reverse osmosis pipeline is made of 304 stainless steel, and the second-stage reverse osmosis and EDI devices are made of 316L sanitary stainless steel pipes;

2. In the first stage reverse osmosis and the second stage reverse osmosis equipment are equipped with on-line conductivity detector meter, in the EDI water production end is equipped with resistivity meter, water production conductivity and resistivity can be watched at any time;

3. There is a low-pressure protection switch in front of the first-stage reverse osmosis, and there are low-pressure protection and high-pressure protection switches in front of the second-stage reverse osmosis;

4. primary and secondary reverse osmosis water recovery rate can be adjusted, primary reverse osmosis recovery rate of 60% -65%, secondary reverse osmosis recovery rate of 70%;

5. The purified water storage tank should be designed as a seamless and dead-end sterile water tank with breathing filter, and the conveying pipeline is equipped with ultraviolet sterilizer and microporous sterilizing filter to ensure that the purified water meets the hygiene requirements.

Structure composition

Reverse osmosis pure watetreatment system generally includes pretreatment system, reverse osmosis device, post-treatment system, cleaning system and electrical control system. Pre-treatment system generally includes raw water pump, dosing device, quartz sand filter, activated carbon filter, precision filter and so on. Its main role is to reduce the pollution index of the raw water and other impurities such as residual chlorine, to achieve the feed water requirements of reverse osmosis. Reverse osmosis device mainly includes multi-stage high-pressure pump, reverse osmosis membrane element, membrane shell (pressure vessel), bracket and other components. Its main role is to remove impurities in the water, so that the effluent water to meet the requirements of use.

Post-treatment system is in the reverse osmosis can not meet the water requirements of the case of increased configuration. Mainly includes negative bed, positive bed, mixed bed, sterilization, ultrafiltration and so on one or more kinds of equipment.

Cleaning system mainly has cleaning water tank, cleaning pump, precision filter composition. When the reverse osmosis system is contaminated water indicators can not meet the requirements, the need for reverse osmosis cleaning to restore its effectiveness.

Electrical control system is used to control the normal operation of the entire reverse osmosis system. Including instrument panels, control panels, all kinds of electrical protection, electrical control cabinets and so on.
