Commercial ro EDI purified water system reverse osmosis water filter Ultrapure water equipment

Pharmaceutical RO+EDI Water Purification Machines

Pharmaceutical Water Treatment Systems is used to purify and deionized water. This system consists of 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 brand can be changes as regards to raw water quality and customer demand.

From touch screen panel, you can see all system flow diagram and automatic or manual control the system.

Membranes do not allow small particles, virus, bacteria to passant EDI module remove all ion from water as a result your water becomes very pure.

Ultrapure water, also known as UP water, refers to water with a resistivity of 18 MΩ*cm (25°C). In addition to water molecules, this kind of water has almost no impurities, and there are no bacteria, viruses, chlorine-containing dioxins and other organic matter. Of course, there are no mineral trace elements needed by the human body, that is, almost all atoms except oxygen and hydrogen are removed. water. It can be used in the preparation process of ultra-pure materials (semiconductor original materials, nano-fine ceramic materials, etc.) using distillation, deionization, reverse osmosis technology or other appropriate supercritical fine technologies.

Although we design system for drinking water treatment system, pharmaceutical industry needs more pure water than drinking water industry. Drinking water treatment system make permeate water’s TDS less than 50ppm, but pharmaceutical industry needs TDS less than 5 to 10ppm.

Pharmaceutical industry needs very high-grade pure water. Greenworld as reverse osmosis company add some special design or modules to water treatments systems. EDI Electrodeionization is one of them.Different than drinking water treatment system, before EDI modules, water pass RO system, as regards to customer demand on purity system can be double pass reverse osmosis system plus EDI electrodeionization system.

EDI Electrodeionization system working principle is based on removing ionized or ionizable species by using electrical active media and electrical potential. Pharmaceutical reverse osmosis electrodeionization system capacity range between 0.1m3/hour to 50m3/hour. Design capacity and option can be customized.

Pharmaceutical reverse osmosis EDI electrodeionization system including most of drinking water treatment system parts. But materials are special, we are using high quality stainless steel 304, 316 or 316L, this material reduce contamination risk.

Ultrapure water equipment uses pretreatment, reverse osmosis technology, ultrapurification treatment and post-processing methods to almost completely remove the conductive medium in the water, and remove the non-dissociated colloidal substances, gases and organic matter in the water to a very low level. water treatment equipment.

.

Reverse Osmosis Electrodeionization water treatment systems are started from booster pump, we suggest to use 316 material for pharmaceutical application, it feeds raw water to pretreatment tanks. Depends on capacity pretreatment tank size and numbers can be changed. Also depend on raw water source and TDS (Total Dissolved Solid) material can be changed. In Greenworld if water source is Tap or low TDS fresh water, we can use Stainless Steel 304 or 316. If salt content and TDS 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 large number of suspended solids, iron, turbidity, unwanted color, unpleasant taste, chlorine, sediment, organic contaminants, odors. In pretreatment we can control the follow manual or automatic for RO + Edi Electrodeionization system.

After pretreatment water goes to cartridge filter housing, we call it as security filter, most of application 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 1µm or 5 µm PP filter in cartridge filter housing at reverse osmosis water treatment system.

The processes for preparing ultrapure water in the pharmaceutical industry are roughly divided into the following types:

1. Raw water → raw water pressure pump → multi-media filter → activated carbon filter → water softener → precision filter → first-level reverse osmosis equipment → intermediate water tank → intermediate water pump → ion exchanger → purified water tank → pure water pump → ultraviolet sterilizer →Micropore filter→Water point

2. Raw water → Raw water pressure pump → Multi-media filter → Activated carbon filter → Water softener → Precision filter → First-stage reverse osmosis → PH adjustment → Intermediate water tank → Second-stage reverse osmosis (the surface of the reverse osmosis membrane is positively charged )→Purified water tank→Pure water pump→UV sterilizer→Micropore filter→Water point

3. Raw water → raw water pressure pump → multi-media filter → activated carbon filter → water softener → precision filter → first-level reverse osmosis machine → intermediate water tank → intermediate water pump → EDI system → purified water tank → pure water pump → ultraviolet sterilizer → Microporous filter → water point

After cartridge filter housing, water goes to membrane pressure vessel with High Pressure Pump, you have brand option for High Pressure Pump such as Grundfos, Danfoss or CNP and it allows you to adjust your budget. Membrane housing shell inside depends on capacity we have 4040 or 8040 Membranes. Most of our project we are using DOW Filmtec, Toray, Vontron, Hydranautics, LG brand.

Membranes, in reverse osmosis electrodeionization system, are most important part. They block if parts size bigger than 0.001µm and molecular weight up to 150-250Dalton. It consists of impurities, particles, sugars, proteins, bacteria, dyes, organic and inorganic solids.

Pharmaceutical RO+EDI Water Purification Machines mostly have 2-pass RO system because of requirement of high purity. Pharmaceutical application ro water plant is more complex than drinking water treatment system.

main application:

1. Production and cleaning of ultrapure materials and ultrapure reagents.

2. Production and cleaning of electronic products.

3. Production of battery products.

4. Production and cleaning of semiconductor products.

5. Production and cleaning of circuit boards.

6. Production of other high-tech fine products.

Ultrapure water can be used in the following areas:

(1) Electronics, electricity, electroplating, lighting appliances, laboratories, food, papermaking, daily chemicals, building materials, paint making, batteries, testing, biology, pharmaceuticals, petroleum, chemicals, steel, glass and other fields.

(2) Chemical process water, chemicals, cosmetics, etc.

(3) Monocrystalline silicon, semiconductor wafer cutting and manufacturing, semiconductor chips, semiconductor packaging, lead cabinets, integrated circuits, liquid crystal displays, conductive glass, picture tubes, circuit boards, optical communications, computer components, capacitor cleaning products and various components and other production processes.

(4) Cleaning of high-voltage transformers, etc.

Also, reverse osmosis water treatment system can have chemical dosing at pretreatment or post treatment, like antiscaling (antiscalant), antifouling, pH adjustment, Sterilization & Disinfection chemicals.

In Greenworld when we check customer water analysis report, sometimes because of scaling and fouling problems, we can use CIP (Clean in Place) System, it wash membrane in membrane housing and make membrane life longer.

We also using UV Sterilizer or ozone generator at reverse osmosis electrodeionization edi water purification system.

Water quality standards:

Outlet water quality: Resistivity＞15MΩ.cm

Industry standards: Ultrapure water quality is divided into five industry standards, namely 18MΩ.cm, 15MΩ.cm, 10MΩ.cm, 2MΩ.cm, and 0.5MΩ.cm, to distinguish different water qualities.
