Ultrafiltration UF water treatment plant system for spring mineral mountain water
UF hollow fiber filter
Ultrafiltration (UF) membrane is a pressure driven type membrane for the water treatment application, and the UF system combines the pre-treatment of media filter and ultrafiltration membrane system, the UF system can be operated at normal temperature between 5 to 45 cent-degree, and the membrane can be operated at a high PH range of 2-12 than other type of membrane. Angel company adopts hollow fine fiber UF membrane with a molecular weight cut-off point of 50000 Dalton in general (30000, 10000, 5000 Dalton will be optional choice for particular requirement).
1).Multi-media filter
The multi-media filter is widely used in drinking water treatment to remove different types of particles, such as suspended solids (turbidity), colloidal compounds and etc, ensuring the filtered water's TDS is less than 5. This process will reduce the load on the back-end fine filters. Diffuser There is diffuser, installed in the filter. Their main function is to make the compressed air and the water distribute evenly during backwash and water distribution.
2) Active carbon filter
The active carbon filter is the key device, commonly used for removal of organic substance and heavy metal element, suspended solids, residual chlorine and etc. It can effectively reduce the level of COD and improve the taste of water. The system is a pressure filter. In the filter, the quartz and Coconut shell activecarbon bed are employed. The activated carbon is equipped with vent valving at the highest point and adrain connection at the lowest point. The internal systems and components for each tank is constructed of frp material.
3) Security filter ( Cartridge Filters)
The security filter is most commonly used for treat water. The whole system adopts one set of stainless filter. There are 5 pieces of polypropylene in every 5μ Filter cartridges, filtering the vast majority of particles in the water, which eases the load of RO membrane. This process of filtration benefits to the filter cartridge and prolongs its lifetime in the system. This apparatus contains filtration component 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. This apparatus is fitted with air drain valve and bottom air drain valve and side drain valve.
4) Reverse Osmosis Modules( RO)
RO system is key part for the water treatment system, which is widely used to make the pure water and drinking water. RO membrane removes many types of large molecules and ions from solutions by applying pressure to the solution when it is on one side of a selective membrane. The result is that the solute such as iron, Virus, bacteria and solids is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side.
5) Piping, Valves & Fittings
The pipe, valves and fittings (including tubing) ball valves, butterfly valves, piping used to the system is SS304. Reverse Osmosis Modules is equipped with sample valve for the convenience to check the product water.
6) Control devices
The whole automatic production line is achieved through the converter and PLC programmer and data collector such as the liquid lever sensor, flow sensor and etc. The whole production line is monitored by remote computer. When the water level of the product water tank is high, the system will stop automatically. When the water level of the product water tank is low, the system will run automatically.
