Pharmaceutical Water Treatment Systems are used to purify and deionized water. This system consists of a booster pump, pretreatment tanks (sand filter, activated carbon filter, softener), SS304/316 cartridge filter housing, chemical dosing systems, high-pressure pump, Stainless Steel 304/316 membrane pressure vessel, 4040 or 8040 RO membranes, Electrodeionization EDI Module, control panel, and touch screen control.

Material and parts brands can be changed as regards raw water quality and customer demand. From the touch screen panel, you can see all system flow diagrams and automatic or manual control of the system. Membranes do not allow small particles, viruses, or bacteria to passant EDI modules remove all ions from water as a result your water becomes very pure. Although we design systems for drinking water treatment systems, the pharmaceutical industry needs more pure water than the drinking water industry. Drinking water treatment systems make permeate water’s TDS less than 50ppm, but the pharmaceutical industry needs TDS of less than 5 to 10ppm.
The pharmaceutical industry needs very high-grade pure water. Chunke as a reverse osmosis company adds some special designs or modules to water treatment systems. EDI Electrodeionization is one of them. Different from than drinking water treatment system, before EDI modules, the water pass RO systems, as regards customer demand on purity system, can be double pass reverse osmosis system plus an EDI electro deionization system. EDI Electrodeionization system working principle is based on removing ionized or ionizable species by using electrically active media and electrical potential. Pharmaceutical reverse osmosis electro-deionization system capacity range between 0.1m3/hour to 50m3/hour. Design capacity and options can be customized.

Pharmaceutical reverse osmosis EDI electro deionization system including most drinking water treatment system parts. But materials are special, we are using high-quality stainless steel 304, 316, or 316L, this material reduces contamination risk. Reverse Osmosis Electrodeionization water treatment systems are started from a booster pump, we suggest using 316 material for pharmaceutical applications, which feeds raw water to pretreatment tanks. Depending on capacity pretreatment tank size and numbers can be changed. Also depending on the raw water source and TDS (Total Dissolved Solid) material can be changed. In Chunke if the water source is Tap or low TDS fresh water, we can use Stainless Steel 304 or 316. If salt content and TDS are high, because of the corrosion, we are using FRP or Carbon Steel material for pretreatment tanks. Pretreatment consists of Sand Media Filter Tank, Activated Carbon Filter Media Tank, and Softener Tank which has ion exchange resin inside, they are very important for reverse osmosis water filtration.
Pretreatment is used to remove a large number of suspended solids, iron, turbidity, unwanted color, unpleasant taste, chlorine, sediment, organic contaminants, and odors. In pretreatment, we can control the following manual or automatic for RO + Edi Electrodeionization system.
After pretreatment water goes to the cartridge filter housing, which we call a security filter, For most of the applications we are using stainless steel 304 or 316 material, but if water is very salty like brackish or seawater, we can use carbon steel or FRP or PVC Plastic Cartridge Filter Housing or Bag Filter Housing. There is a 1µm or 5 µm PP filter in the cartridge filter housing at the reverse osmosis water treatment system. After the cartridge filter housing, water goes to the membrane pressure vessel with High-Pressure Pump, you have brand options for High-Pressure Pumps such as Grundfos, Danfoss, or CNP and it allows you to adjust your budget. The membrane housing shell inside depends on capacity we have 4040 or 8040 Membranes. For most of our projects, we are using DOW Filmtec, Toray, Vontron, Hydranautics, and LG brands.
Membranes, in the reverse osmosis electro-deionization system, are the most important part. They block if the size of the part is bigger than 0.001µm and the molecular weight is up to 150-250Dalton. It consists of impurities, particles, sugars, proteins, bacteria, dyes, and organic and inorganic solids. Pharmaceutical RO+EDI Water Purification Machines mostly have a 2-pass RO system because of the requirement of high purity. Pharmaceutical application RO water plant is more complex than drinking water treatment systems. Also, reverse osmosis water treatment systems can have chemical dosing at pretreatment or post-treatment, like anti-scaling (antiscalant), antifouling, pH adjustment, Sterilization & Disinfection chemicals.
In Chunke when we check customer water analysis reports, sometimes because of scaling and fouling problems, we can use CIP (Clean in Place) System, which washes the membrane in membrane housing and makes the membrane life longer.
We also use UV Sterilizer or ozone generator at reverse osmosis electro-deionization edit water purification system. Electrical Power of industrial water treatment system. For industrial water purification plant needs 220-380V/50Hz/60Hz. For bigger capacity, because of the high-pressure pump, it needs 380V 50/60Hz. As regards your reverse osmosis water filtration machine design, we will check your electrical supply and decide to fix the power for you.
Before Buying a reverse osmosis electro-deionization system, you should know:
1. Pure Water Production Capacity (L/day, L/Hour, GPD).
2. Feed Water TDS and Raw Water Analysis Report (prevent fouling and scaling problems)
3. Iron and Manganese must be removed before raw water enters the reverse osmosis water filtration membrane
4. TSS (Total Suspended Solid) must remove before the industrial water purification system’s membrane.
5. SDI (Silt Density Index) must be less than 3
6. Must be sure your water source does not have oil and grease
7. Chlorine must be removed before the industrial water treatment system
8. Available electrical power voltage and phase
9. Layout of place for industrial RO reverse osmosis system

Advantage of 2-pass RO + EDI Module for reverse osmosis electro-deionization plant
1. Lower conductivity = higher EDI quality
2. Lower CO2 = higher silica removal
3. Ppm-level contaminants mean infrequent EDI cleaning
4. Higher-rated flows for EDI
