Polycrystalline silicon
Polycrystalline silicon, or multicrystalline silicon, also called polysilicon or poly-Si, is a high purity, polycrystalline form of silicon, used as a raw material by the solar photovoltaic and electronics industry. Polysilicon is produced from
High-purity materials are crucial components for the research, development, and production of advanced technologies which require optimum properties, performance, and quality. We offer ultra-high purity salts with purity exceeding 99.998% (less
POLY ALUMINUM CHLORIDE
Cinetica Quimica is a supplier and manufacturer of poly aluminum chloride for the water treatment sector In Cinética Química we are leaders in the manufacture of Poly Aluminium Chloride, aluminum chloride hexahydrate and aluminum chlorohydrate.
High purity aluminum foil for the anode is etched by electrochemical process in a chloride solution with DC, AC, or an alteration of DC and AC, or a concurring AC and DC current. Fine surface etching (photo 1-1) accomplished mainly by AC
Brief review of the chemistry of polyphosphoric acid (PPA) and bitumen - MIT - Massachusetts Institute of Technology
5 which is used to provide high purity material (30, 31). A cheaper wet process provides H3PO4 from the reaction of sulphuric acid on ground apatite phosphate rock, Ca3(PO4)2CaF2 (30, 31). [Figure 2] PPA is an oligomer of H3PO4.High purity mater
High Purity High purity aluminas are normally classified as those with a purity of 99.99% and can be manufactured by routes starting from Bayer hydrate using successive activations and washings, or via a chloride to achieve the necessary degree

Linear alkylbenzene
Linear alkylbenzenes (sometimes also known as LABs) are a family of organic compounds with the formula C6H5CnH2n+1. Typically, n lies between 10 and 16, although generally supplied as a tighter cut, such as C12-C15, C12-C13 and C10-C13, for
DEAC, Diethylaluminum chloride, CAS 96-10-6, Metal Alkyls organometallics, DEAC is an aluminum alkyl used as a co-catalyst in the Ziegler-Natta polymerization of olefins. Downloads Product Data Sheets PDS DEAC
Poly Aluminium Chloride (PAC) - Water Treatment Chemical
Poly aluminium chloride in water treatment has the characteristics of good coagulation performance, large alum particles, fast settling, low dosage, high efficiency, and wide application range. So it mainly used in treating urban drinking water
Aluminium chloride (AlCl 3), also known as aluminium trichloride, describe compounds with the formula AlCl 3 (H 2 O) n (n = 0 or 6). They consist of aluminium and chlorine atoms in a 1:3 ratio, and one form also contains six waters of
- Is Luxembourg compliant with “urban waste water treatment directive”?
- So from previous newsletters you know quite well that that nation branded Luxembourg is still not compliant with “urban waste water treatment directive”, providing for secondary (biological) waste water treatment, and even more stringent treatment where necessary although this directive was adopted in 1991, so 25 years ago !
- Why was water treatment important in the 19th century?
- Water treatment. Anticipating the next century of wastewater treatment Rapid urbanization and industrialization in the 19th century led to unhealthy environments and wide-spread epidemic diseases. In response, research was undertaken that led to the development of sanitation technology.
- Who invented the settling and recycling of sludge inside treatment plants?
- The settling and recycling of sludge inside treatment plants was the invention of Ardern and Lockett. The current demands from a rapidly growing human population and the need for a more sustainable society are pushing forward new developments for sewage handling.
- Is a net energy-producing treatment plant possible?
- With the recent advance of Anammox technology, a net energy-producing treatment plant, including effective nutrient removal, is becoming feasible ( 11 ). Although the recuperation and production of energy at sewage works is currently getting most attention, the resource recovery from wastewater and sludge should not be overlooked.
