Programmable Solid Powder Dosing Machine
With the dosing units you can easily and reliably condition the water to serve the intended use and to meet the technical
requirements. The field of applications includes the dosing of:
* Acids for alkalinity reduction and scale prevention
* Polyelctrolytes for coagulation of suspended solids and an improved subsequent filtration
* Scale inhibitors to avoid scale deposits on reverse osmosis membranes
* Disinfectants for shock treatment in order to avoid bacterial growth
* Chlorine to avoid biological growth in pipes and storage tanks
* Hydrated lime or caustic soda for pH adjustment to neutralize dissolved free carbon dioxide.

Q: What is Reverse Osmosis?
A: Reverse osmosis (R/O) is a water treatment process in which water is forced through a semi-permeable membrane that has very small holes or "pores". Clean water passes through and impurities that are too big to pass through the membrane are left behind and flushed away.
Q: How Does Reverse Osmosis Work?
A: Reverse osmosis systems purify water by forcing pressurized water through a very fine, plastic membrane. If the raw water being treated comes from a well or another private source, disinfection and pre-filters (to remove chlorine and/or particulates/sediment) may be needed in advance of the R/O unit to remove contaminants that can foul or damage the membrane.
Q: How Do I Know What Size Unit to Buy?
A: R/O units are rated according to the amount of treated water produced per day. For example, one type of unit produces 5000 liters of treated water per day under its design conditions. In reality, conditions frequently vary. Line pressure is often lower, water will frequently be colder than 25° C and backpressure in the storage tank will likely reduce the performance of the unit. Consequently, you should examine water conditions and buy a larger rated unit than needed if any of the above problems are noted
Q: Material of reverse osmosis system?
A: You can choose FRP filter + U-PVC pipe, stainless steel filter + U-PVC pipe or total stainless steel.
