Spirit PFS sample liquid ferric chloride into the clean, dry cylinder, not a bubble. The cylinder is placed in a constant temperature water bath (20 ± 1) ℃ in. When the temperature constant, it will hydrometer slowly into the sample. Density meter in the sample to be stable, Zhaodong PAC, read the next meniscus edge densitometer scale (marked with meniscus edge densitometer scale excluded), the sample is 20 ℃, density. Spirit PAFC (PAFC) is made of aluminum and iron salts coagulation hydrolysis of an inorganic polymer coagulant, based on the principle of synergy, adding or three elemental iron oxide and other iron-containing compounds compound and A new and efficient system coagulant obtained. It not only made the people's recognition in the crop also has an immediate effect in terms of treating wastewater. This PAFC original effective surface of the sand quicksand condensed into pieces, PAC standards quicksand like to put on a coat, planting trees and grass on top, it can make the desert into an oasis. Sprinkle some of the ferric chloride in saline solution in a few hours later, PAFC put the saline-alkali soil particles molded into countless round yo like pea-sized. These particles can withstand the test of wind and rain the sun, the crop can be grown in saline root. The ferric chloride solution is sprinkled on the lake zone of mud, a few days later, mud flats became good soil loose granular porous. PAFC classification: 1. form a solid ferric chloride after drying, with a convenient transport advantages, no tanker, the disadvantage is the use of dilution also be required to increase the intensity of work .2 liquid PAC. iron undried form, there is no dilution, loading and unloading easy to use, relatively cheap advantages, disadvantages tanker transport needs, increasing unit transportation costs (equivalent to 2-3 tons per ton of solid liquid). How to use PAC to achieve the best results we know that different amounts of water quality and the number of PAC iron water use are different, then how can we make PAFC best effect? Would like to know, please read on! 1, before using this product at a certain concentration (10-30%) alum solution into the pool, into the fully hydrolyzed water stirred and allowed to stand to reddish brown liquid, then diluted with water to the desired concentration dosing coagulation . 2-5% water can also be dubbed in direct dosing, industrial wastewater treatment formulated 5-10% direct dosing. 2, dosage is determined, based on the nature of the raw water may be formed by commissioning or beaker experiment, as the right amount of alum may be prepared another dose of the original water can use as a reference, the product and the solid polymeric chloride under the same conditions roughly the same amount of aluminum, a solid amount of aluminum sulfate 1 / 3-1 / 4. If the original using a liquid product, PAC prices can be calculated according to the discretion of the appropriate drug concentration. Approximate weight ratio of 1: 3 may be. 3, when used, Spirit PAC, said the prepared liquid, pumped into the measuring tank, dosing liquid raw water through the measurement of coagulation. 4, the date of the preparation of the day in general use, dispensing needs water, a slight sediment is normal. Spray PAC, PAC Zhaodong, Saatchi Saatchi water provided by the Henan water purification Material Co., Spray PAC, PAC Zhaodong, Saatchi Saatchi Henan water purification Material Co., Ltd. (www.gyssjs.com) this year introduced a new upgrade, the above picture is for reference only, please call this page or image Contact phone, for the latest information, Contact: Zhang.
