3000LPH RO water purifier machine for plant technical process

The water is first being removed the suspended matter, micelle and other impurity by the quartz sand filter. Then it is being got rid of the organic substance, chlorine, chroma, odor and etc by the active carbon filter. The above two steps compose the consummate pretreatment system. The water which is being pretreated reaches the requirement of the RO system. So as to make the RO equipment run stably during a long period.

The abio-salt, organic substance, bacteria, heat source and other impurity in the water have been removed after the water was being treated through one grade RO system. The ratio of salt-doffed is in the range of 97%-99%. The water quality is accord with requirement of Hygienic standard of bottled purified water for drinking GB 17324—2008.

3000LPH RO water purifier machine for plant technical index:

a. Output water flux: 3M³/h Water temperature: 25℃

b. Output water quality: Accord with National bottle drinking water standard GB17323-2008. Main contracture of the filtering system: Quartz sand filter, active carbon filter, Precision filter, Reverse Osmosis system, Membrane cleaning system, PLC control system, Ozone generator

System requirements for outside plant

Inlet pipe: The inlet pipe are buried one meter away from the water treatment area
Outlet pipe: The outlet pipes are long enough to the product water pump valve (This to be decided after the plan sketch is provided)
Water drain: Drained out in ditch of plant (decided and built by the user) Functions of the machine: RO membranes auto wash and manual wash RO membranes manual wash with medicine Pure water high water level auto stop, low water level auto start Multi-phases pump protected without water Protected when no power, poor power, over electrical current, short circuit, circuit breaker, leakage protection.

RO Device

The RO device removes the hydronium, organic substance, colloid, bacteria and other impurity by the method of membrane. And the water can be desalted and purified. The theory is as follows. The treated water and the untreated water are separated by the membrane; the treated water osmoses to the untreated water. There is osmotic pressure between the two. If the pressure is added to the untreated water and the pressure of the untreated water is bigger than the osmotic pressure, the water of the untreated water osmoses to the opposite position of the water. This applies the reverse osmosis to the desalted water. That is to say the untreated water is purified into the pure water through the RO membrane under adequate pressure. The left water which can not osmosis through the membrane contains a lot of solute and suspended substance, and it will be drained out as waste water.
The water must be pretreated before entering into the RO system, or it will bring damage to the RO membrane.
The RO system not only can be used for desalination, but also for filtering the organic substance and bacteria.
The production of water is monitored by the liquid crystal display conductivity meter.
The RO system needs be cleaned timely, including the stainless steel pump, filter, disinfectant tank, valve and other components.
Commonly, the RO system should work once every day. If it does not work in one week, it must be protected by some measures, or the service life of the membrane will be serious affected.
RO device employs low pressure large flux membrane made by American Dow Company. The type is American Dow BW30-400 Ro Memebrane, and it has five of them. The membranes can serve for years in good maintenance. This instruction explains the details of operation and maintenance methods. The RO device removes the hydronium, organic substance, colloid, bacteria and other impurity by the method of membrane. And the water can be desalted and purified. The theory is as follows. The water and the solution are separated by the membrane; the water osmoses to the solution. There is osmotic pressure between the two. If the pressure is added to the solution and the pressure of it is bigger than the osmotic pressure, the water of the solution osmoses to the opposite position of the water. This applies the reverse osmosis to the desalted water. That is to say the raw water is purified into the pure water through the RO membrane under adequate pressure. The left water which can not osmosis through the membrane contains a lot of solute and suspended substance, and it will be drained out as waste water.

Quartz Sand Filter, 1th Prepare Filter For RO Device

In order to protect the back-end filters, we adopt the quartz sand filter .

Quartz sand filter (Optional manganese sand）Removed big suspendid of raw water. Remove different types of particles, such as suspended solids (turbidity), colloidal compounds and etc.

Quartz sand filter will reduce the load on the back-end filters Water production index: SDI<1-3.

After a period of time, the filter will be saturated. In order to restore its function, the filter needs backwashes. In order to achieve its best results, the efficient backwash needs taking 20-30min. This filter is fitted with two diffusers, a manhole for discharge media.

Activated Carbon Filter, 2th Prepare Filter For RO Device

In order to protect the back-end filters, we adopt the active carbon filter .

Active carbon filter remove of organic substance and heavy metal element, suspended solids and etc. It can effectively reduce the level of COD and improve the taste of water.

With a valve operating system, pipeline system, containing the manhole, hand hole, the upper and lower water distribution devices, media, pressure.

After a period of time, the media will be saturated and it needs backwashes. In order to achieve its best results, the efficient backwash needs taking 20-30min. This filter is fitted with two diffusers, a manhole for load media..

Precision Filters, 3th Prepare Filter For RO Device

Prevent the particles entering the membrane, scratched the surface of the membrane. In the normal operating condition, the filter can maintained for 3 mouth. The filter structure for fast replace.

Manufacture of high quality PVC material. Filter holder containing a fixed The 5μm PP filter is most commonly used for dealing the pure water. It is generally believed that the harmful particles and bacteria are larger than 0.22μm.

In order to prolong the life of RO membrane, the whole system adopts one set of stainless pp filter. The polypropylene microporous filter cartridges with the length of 40 inch in 5μm filters respectively. The 5μm filter acts as the protector of the RO membrane, filtering the vast majority of particles in the water, which eases the load of RO membrane and prolong its life.

The filter cartridges are for one-time use, as the particles retained in the gap of microporous filtering film is hardly removed by rinsing with acid-base. After a period of time, the filter cartridge needs to be replaced. The structure of them makes replacement of cartridge convenient. This apparatus contain filtration cartridges and stainless support layers. The support layer is made of stainless steel 304, with the advantages of compact structure, beautiful shape, high flux, good filtration accuracy and etc.
