Softening water and other equipment

Chemical, automotive, electroplating, precision machinery and special materials industry water equipment

According to the different water quality of raw materials, production processes and production equipment, tap water is difficult to meet its needs。The company in accordance with the customer's proposed water source conditions and water quality, water requirements, comprehensive consideration, to provide customers with quality products and services。Water yield: 0.5t/h-200t/h

Chemical industry

In the chemical industry, volume water, chemical analysis, product cleaning, material separation, concentration, purification, waste recycling and other occasions need to use membrane separation equipment, with water conductivity up to 20μs/cm-0.1 mu s/cm

Common process

Tap water → pump → multi-media filter → high pressure pump → security filter → automatic feeding device → reverse osmosis → Ultraviolet → pure water tank tap water → pump → primary reverse osmosis → intermediate water tank → High pressure pump → secondary reverse osmosis → pure water tank

Automobile industry

The pure water used in the coating process in the automotive industry usually has a conductivity of 10μs/cm-5μs/cm or less, to use and reverse osmosis or secondary reverse osmosis process, the use of ultrafiltration membrane technology can also separate and recycle the electroplating paint after cleaning, separated out and returned for cleaning。

Common process

Tap water → pump → multi-media filter → automatic counterfeit device → security filter → high pressure pump → primary reverse osmosis → intermediate water quality → High pressure pump → secondary reverse osmosis → pure water tank

Tap water → booster pump → multi-media filter → softener → security filter → high pressure pump → reverse osmosis → finished water tank

Ion exchange equipment

Ion exchange is to remove various ions from water through negative and cation exchange resins, which has the characteristics of low investment cost and can be divided into cation exchangers, anion exchangers, mixed ion exchangers and so on。

Hybrid ion exchangers are mainly used for deep desalination after RO reverse osmosis equipment。Because it often requires chemical acid-base regeneration, the operation is complex, and it is gradually replaced by EDI electrical separation technology。

Common process:

One: raw water → quartz sand filter → activated carbon filter → positive bed degassing tower → negative bed → mixed bed water point

Two: raw water → quartz sand filter → activated carbon filter → security filter →RO film unit → ultraviolet sterilizer → pure water tank → pure water pump → mixed bed → precision filter → water point

According to user requirements and process characteristics, the main material of the ion exchanger can be selected as composite material, carbon steel or stainless steel material。

Ultrafiltration equipment

It is a membrane separation process based on the sieve separation principle and the pressure as the driving force, and the filtration precision is 0.005-0.In the 04μm range。It can effectively remove particles, colloids, bacteria, microorganisms and polymer organic substances in water。It is widely used in the separation, concentration and purification of substances。

The ultrafiltration process does not need to change, works at room temperature, is particularly suitable for the separation of heat-sensitive substances, and has good oxidation resistance, can be used for a long time under 60 ° C, pH 2-11 conditions。

Ultrafiltration equipment is widely used in medical sterile non-thermal raw water equipment, food and beverage, drinking water, mineral water purification, industrial separation, concentration, purification, industrial wastewater treatment, electrophoretic paint, electroplating oily wastewater and other fields。

At present, there are reverse osmosis systems that use ultrafiltration as the pre-treatment of reverse osmosis in order to increase the amount of reverse osmosis water and extend the life of reverse osmosis membranes。

5. Softened water boiler and cooling tower water equipment

Water quality standards: in line with the national or industrial boiler feed water standards (GB157679, DL/T56195), suitable for a variety of medium and high pressure boiler water quality requirements。

Typical process flow:

One: pretreatment → reverse osmosis → ion exchange → salt removal

Two: Pretreatment → reverse osmosis equipment

Three: pretreatment → cation exchange softening

Pretreatment equipment

Mainly includes multi-media filter, softener, security filter。Generally used as a water treatment system front, to protect the UF(ultrafine)RO(reverse osmosis) or ion exchange system behind。Multi-medium filter is mainly used to remove suspended particles, organic colloidal substances, Fe, Mn and other heavy metal ions in water, reduce the turbidity of raw water, raw water quality is different sometimes need to add flocculant。

The multi-media filter can be loaded with a variety of filter materials (quartz sand, anthracite, activated carbon, manganese sand, etc.), or a variety of single filter material filters in series to adapt to the removal of various impurities in the water to meet the requirements of the back-end system。The softener can effectively remove the Ca and Mg plasma in the water, thereby reducing the hardness of the raw water to maximize the life extension of the reverse osmosis equipment

Medicine, hospital supply room, pharmaceutical purified water equipment

Purified aquatic water index

Chemical index: In line with the People's Republic of China Pharmacopoeia 2005 version of pharmaceutical pure water requirements
