Bastnasite containing about 50 wt% cerium, 0.20.3 wt% thorium and 810 wt% fluorine is one of main sources of RE in China . Light RE, such as lanthanum, cerium, praseodymium, neodymium and small amounts of samarium, europium and gadolinium, are the main components of minerals, while heavy RE are in very small amount.
Then, the sludge to be treated is conveyed with pressure to the filter press 25 by the condensation tank pump 24 and then dehydrated. The filter press 25 is a dehydrator having a relatively good dehydration property, and a dehydrated cake having a moisture content of not greater than 60% is obtained by this filter press
Sodium fluoride tablets containing 1 mg of fluoride ion should not be used in children younger than 6 years of age and are contraindicated when the fluoride ion concentration in drinking water is 0.3 ppm (mg/L) or greater.
The initial step in ceramic tile manufacture involves mixing the ingredients. Sometimes, water is then added and the ingredients are wet milled or ground in a ball mill. If wet milling is used, the excess water is removed using filter pressing followed by spray drying.
The manual is an in depth presentation of the steps required to design and operate a fluoride removal plant using activated alumina (AA), which is a reliable and cost effective process for treating excess fluoride from drinking water supplies.
May 16, 20000183;32;Then, the waste water treatment equipment consists generally of the above seven water tanks 61 to 67, a slaked lime tank 68 and a filter press 70. Into the first water tank 61, hydrogen peroxide and phosphorus containing fluorine waste water is introduced and stored through piping from production equipment of the factory.
The bag filter can remove more than 0.1 micron particle size of dust particle, the dust removal efficiency 99%. Purification high temperature gas, can use glass fiber filter materials. It is easy to dismantle and clean, and suitable for refueling operation.

Abstract. The CEA is studying the development of processes with a sufficiently large operating range in order to propose a general treatment system and make it possible to absorb a significant quantity of radioactive liquid stocks awaiting treatment around the world.
The method of hanging the lime filter paper in indoor was a piece of lime filter paper should lie on the bottom of the sampling box and be fixed by the circlip . The sampling box with filter paper should be 1.5 m away from the stove and about 1.5 m away from the ground.
For dehydration, the sludge, which has moved to the fluorine concentrated sludge tank 15, is introduced into a filter press 17 by a filter press pump 16. FIG. 2A shows an example of the residence time of waste water in each tank when the fluorine concentration is normal (about 80 ppm) and the TOC concentration is normal (about 2,500 ppm).
Ion exchange filters are made from lots of zeolite beads containing sodium ions. Hard water contains magnesium and calcium compounds and, when you pour it into an ion exchange filter, these compounds split apart to form magnesium and calcium ions.
