Reverse osmosis is a great way for any home user to remove fluoride as well as any other contaminant from the water. However, it does remove many wanted minerals like calcium and magnesium from the water. A great alternative is to use a simple combination of filter cartridges with carbon and activated alumina. Carbon filtration is perfect for any standard filtration and the activated alumina works best for fluoride removal. Activated alumina works with all types of water filtration systems. These kinds of replacement water filters may cost more than your average carbon filter but they are well worth the money. Activated alumina filters require a very slow flow rate. For every cubic foot of activated alumina (approx. 44 lbs.), the service flow is only 1-2 gallons per minute (GPM) per cubic foot. This means that for a small drinking water unit which uses only 1.5 lbs of media, the service flow is only 0.068 GPM. This is equivalent to a drip of water per minute. Getting water never seemed so slow - but the way to properly get this flow is to use something called a flow restrictor of approximately 110 ml/min and use a pressurized tank to store the water until you are ready to drink it. This way you will have a reservoir holding filtered water free of fluoride. Both methods of removing fluoride are great and both have many benefits. Reverse osmosis typically strips all elements - good or bad - in the water in order to give the most purified water possible. Activated alumina when combined with carbon filters and a flow restrictor will also give you great purified water free of fluoride without incurring larger maintenance costs of replacement water filters. The cost of replacing water filters for a reverse osmosis system every year may cost you $40-50 while changing out the activated alumina filter system could also cost about $40. It's all a matter of preference. One thing is for sure, we want to remove fluoride from the water because we already get enough of this from the toothpaste and foods that we eat.
Xintao 92% Alumina Grinding Ball for Indonesia Powder Industry
Dry grinding is widely used in mining, ceramics, powder and other industries. In view of the situation of raw materials polluted by grinding media abrasion, we have developed special dry grinding ball with high strength and low abrasion to solve this problem.
Application of Alumina Ceramic Balls
Ceramic balls can be divided into ceramic balls and grinding ceramic balls. Ceramic balls are widely used in petroleum, chemical, fertilizer, natural gas, environmental protection and other industries as the cover support material and tower packing of the catalyst in the reactor.

The models selected by customers are usually CMS-240, CMS-260. The nitrogen concentration is 99.5-99.99% and above, which has won a series of praises from customers.
PSA nitrogen making
PSA technical(Pressure Swing Adsorption,PSA for short) :it’s a kind of afvanced gas separation technology,based on physical adsorption of gas molecule on the internal surface of adsorbent(porous solid substances),using adsorbents in the same pressure easy to absorb the high boiling point gas,difficult to absorb low boiling point gas.amd under high pressure adsorption amount of absorbed gas increases,under low pressure adsorption of absorbed gas to reduce the features to achieve gas separation.
Pressure Swing Adsorption (PSA) - Hydrogen Purification
Pressure Swing Adsorption (PSA) from Air Liquide Engineering & Construction is used to recover and purify hydrogen from a variety of hydrogen-rich streams. Xintao 5A Molecular Sieve for hydrogen production, is a special molecular sieves for hydrogen production by pressure swing adsorption.
The packed column used for the separation of distillation is a vertical cylindrical vessel containing an appropriate packing bed supported and irrigated by the liquid flowing through a particular distributor. The bed height is determined by the packing mass transfers capacity and constrained are governed by allowable pressure drop and the overall column height.
Molecular Sieve Activated Powder in Polyurethane Industry
XINTAO series molecular sieve activating powder added to polyurethane and other product systems can effectively and selectively absorb trace water in typical polyurethane formulations, inhibit the occurrence of side reactions, thus reducing the generation of bubbles and extending the application period.
