Ultra pure water equipment has become one of the widely used water purification technologies nowadays, and its key practical significance depends on changing a period and promoting its development. How many people have mastered the common solution systems of ultra pure water equipment? How many types of such systems are there? Now let the editor lead everyone to understand.

Composition of pre-treatment system for purified water equipment:

1. Raw water pump

The raw water pump is the percentage of water pressure in the raw water pretreatment system. If it were not for this equipment, the working pressure of the raw water could be completely eliminated. General regulations on the working pressure of raw water= 0.3MPa.

2. Raw water tank

The function of the raw water tank is simpler, which is to store it with raw water. It is a sale that is afraid of raw water (generally, the fluctuation power switch is more automated technology for all mineral water production line equipment).

3. Stone sand filtration device

Select a quartz sand filter to remove floating fine sand, fine sand, and residue from the raw water, reducing the turbidity of the water. It can also remove organic compounds, bacteria, viral infections, and other organic compounds from water, creating excellent standards for water disinfection and sterilization.

4. Activated carbon filter

Reasonably adsorb the adsorption capacity of activated carbon for organic compounds in source water, permanganate index, colloidal solution, particulate matter, microbial species, some metal ions, and fading.

5. Softening system

Ionic resin exchange capacity can remove sodium and aluminum ions from water to avoid the actual effect of scaling on machinery and equipment afterwards. However, the actual operation involves the cost of manpower and water treatment accessories. The current drug delivery system immediately adds retarders.

Whether using EDI equipment immediately or ion exchange systems, combined with RO reverse osmosis systems, general groundwater, drinking water, and industrial water cannot meet the infiltration requirements of ion exchange epoxy resin or RO reverse osmosis for pollutant chemicals. Only after moderate pre-treatment of the raw water can the water treatment system meet the requirements for seepage water bodies. Below, authoritative experts from Shenzhen Kerui Environmental Protection Machinery Co., Ltd. will analyze several common pre-treatment methods in the raw water end of pure water equipment.

Stone sand filtration device

Stone sand filtration is one of the reasonable ways to remove suspended solids in water, and is a key module in deep wastewater treatment, wastewater recycling, and water supply and drainage solutions. Its function is to further remove air pollutants from the inclined plate sedimentation tank in the water. Based on the interception, foundation settlement, and adsorption effects of the filter material, it achieves the goal of purifying water. The raw water generally contains fine particles of dust, cassava starch, methyl cellulose, and other microbial species such as bacteria and algae. The colloidal solution particles generated by the residue and water, due to the electrostatic induction of Brownian motion, exhibit the reliability of foundation settlement and convergence. Generally, they cannot be removed by natural foundation settlement under the action of force.

Activated carbon filter

Activated carbon filter is a common water purification equipment, used as a pre-treatment for wastewater treatment desalination systems. It can adsorb the permanganate index that cannot be removed in the previous filtration, reasonably ensure the service life of subsequent machinery and equipment, improve the effluent water quality, and avoid environmental pollution; In addition, it also adsorbs pollutants such as small molecule water organic compounds that have leaked back from previous stages, and has significant adsorption and removal effects on odor, colloidal solutions, melanin, heavy metal ions, etc. in water. It also has the effect of reducing COD. The activated carbon filter mainly filters the permanganate index in the water. When the permeability index value of permanganate is< 50 mg/L.

Reverse osmosis equipment

Reverse osmosis equipment, also known as multi-media filters, has the function of intercepting more than 2% of the raw water μ M particles are used to ensure that the reverse osmosis membrane is not scratched by suspended solids of large particles. Due to the thickness of the reverse osmosis membrane being approximately 10 μ Up and down, large particles in the raw water can easily scratch the desalination skin on the surface of the reverse osmosis membrane or potentially penetrate the reverse osmosis membrane components after being accelerated by the high-pressure water pump. Generally, a 5-micron reverse osmosis equipment is installed in front of the reverse osmosis membrane machine equipment. In sewage treatment systems, precision filtration is generally used as a process for treating raw water entering the reverse osmosis membrane gel, in order to avoid potential leaks in the previous process and prevent blockage of the reverse osmosis membrane.

Above is a detailed introduction to several common pre-treatment systems for ultrapure water equipment. The protection equipment of ultrapure water equipment maintains it reasonably, which is one of the key components of machine equipment.
