5000LPH RO Water treatment machine
Brief introduction 

RO water treatment equipments is generally adopted by pure water plant,mineral water plant,bottled water plant, beverage processing plant, etc. and used in pure water production line, beverage production line, fruit juice production line, yogurt production line, and more. Reverse osmosis water purification is the removal of contaminants from untreated water to produce drinking water that is pure enough for its intended use, most commonly human consumption. Substances that are removed during the process of drinking water treatment include suspended solids, bacteria, algae, viruses, fungi, minerals such as iron, manganese and sulphur, and man-made chemical pollutants including fertilisers.

1). This system adopts the most advanced Reverse Osmosis pure water filter technic. Its water production conductance rate generally less than 10us/cm, which precedes the national standard GB17323-1998. The reverse osmosis water made by this RO system is asepsis, non-granule and pure.
2) The RO membranes of this system adopt American hydranautics membrane or the American Dow membrane

Function

Prevention of membrane fouling (including Fe3, Fe2, CaCO3, CaCO4, SrSO4, CaF2, SiO2, iron, aluminum oxide).
Prevention of colloidal material and suspended solid particles from plugging.
To prevent organic fouling
To prevent microbial fouling
To prevent the oxidation of substances on the oxidative damage to membrane
To maintain the ultrafiltration plant capacity stability
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,large electrical cuttent short circuit,creepage of electricity.
In light of corrosion, pressure, vibration and temperature when choosing filter materials, we offer tailor-made solutions according to raw water conditions of our customers. For example, if the TDS of raw water is very high, customers will be recommended to use fiber glass filter tank so as to optimize the whole water treatment system and also prolong the life of the reverse osmosis water treatment equipment.

Whole line technical process

Reverse Osmosis Water Purification System

1.Raw water tank
It use to storage raw water, Stable Ro system raw water flow and pressure,protect the raw water pump. The raw water tank with built-in water stainless steel ball valve and liquid level controller.

2. Raw water pump
Brand: China South Pump. It will deliver the raw water to the system, it is control by PLC. Liquid level controller can control the booster pump’s start and stop.

3. Quartz sand filter
It is widely used in RO system to remove different types of particles, such as suspended solids (turbidity), colloidal compounds and etc. This process will reduce the load on the back-end filters


4. Carbon filter
The active-carbon filter is commonly used for removal 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 . After the quartz sand filter and active carbon filter, the water basically required the water treatment plants water standard: SD1 ≤ 4; TDS≤400

5. Security filters:
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.

6.High pressure pump.
High pressure pump is mainly to add pressure of the inlet water into a certain standard so that the pressure difference will be enough for the Reverse Osmosis need,


7. RO Membrane
It can 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.
