Mineral Water Treatment System / Ultrafiltration Water Filter

Mineral Water Treatment System / Ultrafiltration Water Filter
Ultrafiltration(UF) membrane functions as the core part of the whole system to produce mineral water. Ultrafiltration (UF) membrane serves as a molecular sieve. It separates dissolved molecules by passing a solution through an infinitesimally fine filter. The ultrafilter is a tough, thin, selectively permeable membrane that retains most macromolecules above a certain size, including colloids, microorganisms and pyrogens. Smaller molecules, such as solvents and ionized contaminants, are allowed to pass into the filtrate.

Mineral Water Treatment System

1. Definition of mineral water
Mineral water is water containing minerals or other dissolved substances like calcium, magnesium, sodium, potassium, silica and bicarbonates, which is healthy to drink.

Our water treatment systems are customized and designed to meet the local water conditions and flow rate requirement. The mineral water treatment equipment utilizes a quartz sand filter, active carbon filter, and PP filter for the treatment of raw water. This process not only removes large particles, odor, color, and some bacteria, but protects back-end UF membranes, which helps prolong the life of the equipment.

The ultrafiltration(UF) membrane functions as the core part of the whole system to produce mineral water. Ultrafiltration (UF) membrane serves as a molecular sieve. It separates dissolved molecules by passing a solution through an infinitesimally fine filter. The ultrafilter is a tough, thin, selectively permeable membrane that retains most macromolecules above a certain size, including colloids, microorganisms and pyrogens. Smaller molecules, such as solvents and ionized contaminants, are allowed to pass into the filtrate. Thus, UF provides retained retentate that is rich in large molecules and a filtrate that contains few, if any, of these molecules.

2. Filter material of Ultrafiltration Water Treatment System 
When choosing filter materials, we offer tailor-made solutions in view of corrosion, pressure, vibration and temperature, as per raw water conditions of customers. For example, if TDS of raw water is too high, fiber glass filter tank will be recommended in order to optimize the whole water treatment system.

What is Ultrafiltration?

Ultrafiltration is used to treat drinking water:it improves the quality and shelf life of the water.Ultrafiltration is using hollow fiber filtering technology, with three levels of pretreatment filtering to remove impurities in the water; ultrafiltration pores less than 0.01 microns, can be completely filtered water, rust, bacteria colloidal and other harmful substances, retain the water on the human body useful trace elements and minerals.

Ultrafiltration principle

Ultrafiltration is a membrane separation technology, i.e., under a certain pressure,made the small molecules of solute and solvent through certain pore size special membrane,super and macromolecular solute impermeable membrane,left side.
Ultrafiltration principle is a membrane separation process principles, ultrafiltration using a pressure activated membrane, in the external driving force ( pressure ) under the effect of colloidal particles in water interception, and the relatively higher molecular weight material, and water and small solute particles through a membrane separation process. Through the membrane surface of the microporous filtering may be cut-off molecular weight of 3×10000 – 1×10000 material. When the water to be treated by external pressure to flow through the membrane surface, the water molecules and the molecular weight of less than 300 – 500 of the solutes through the membrane, rather than a hole of the membrane microparticles, large molecules such as sieving action are retained, thereby allowing the water to be purified. That is to say, as the water passes through the membrane, the water containing colloidal silica to remove most, at the same time can remove large amounts of organic matter.

The device configuration and performance

SUS304 Raw water tank (aseptic tank)
If the booster pump direct extraction pipe water,May because of lack of water flow and the instability pressure lead to damage
the pump or affect the normal operation of the system, Use one raw water tank to offer water can advoid that happen.
The raw water tank with built-in water stainless steel ball valve and liquid level controller, large equipment need a water inle
of electric butterfly valve.
1.Inlet valve function is control of raw water into the water, make sure the system can timely replenishment water.
2.Liquid level controlled have middle water level and low water level, Its function is to control the booster pump’s start and
stop; when the water level above the water level, the booster pump can be started automatically; when the water level is
below the low water level, booster pump auto stop.
SUS304  Pure water tank(aseptic tank)
Its used to store pure water
Water tank has three water level:high level,middle level,low level, when the water level at low level the pure water pump automatical stop supply water until the water of the pure water tank water level reaching or above the middle water level can be automatically activated, restoration of water supply; water level below the middle water level the high pressure pump automatic starting the system to producing water until the water level reach the  high level, high pressure pump auto stop running.

Quartz sand filter
The high-quality 304 stainless steel with a valve operating system, pipeline system, containing the manhole, hand hole, the upper and lower water distribution devices, media, pressure.
Quartz sand filter is mainly used to remove suspended matter and sediment, particle impurity. The device and other water treatment equipment, widely used in water purification process. Quartz sand filter filled with refined multilayer multipath quartz sand, anthracite, fiber ball. In room temperature operation, with acid and alkali resistance, oxidation resistance, application range of PH to 2-13.
System provide protection devices and monitoring instruments, and have automatic backwashing function, dirt and other pollutants can quickly swept away,consumpt less water
Under a certain pressure, made the liquid through the medium of contact flocculation, adsorption, retention, removing impurities, thus achieve the purpose of filtering.
Filter design should fully consider the backwashing intensity, unstable system operation causes are mechanical filter recoil design flaws, the recoil is not complete, the upper filter sand agglomerates SDI ( pollution index ) increased, causing membrane fouling. Considering the mechanical filter backwashing after put into use, filter layer surface formed in the late, impurity penetration, considering the poor effect and other factors, so the use of low flow work, in order to improve the filtering effect, reduce the impact of follow-up processing.
Activated carbon filter:
