water treatment agent product composition analysis

water treatment agent is a general term for a class of chemical agents used in water treatment, widely used in petroleum, chemical, metallurgy, transportation, light industry, textile and other industrial sectors. water treatment agents include corrosion inhibitors, scale inhibitors, biocides, flocculants, purifiers, cleaning agents, pre-film agents, etc.. in practice, often use a composite formula of water treatment agents, or a combination of various types of water treatment agents.

common water treatment agents include: flocculants, ferrous sulphate heptahydrate, polymeric iron salts, calcium hydroxide, ferric chloride hexahydrate, algaecide, chlorine dioxide, scale and corrosion inhibitor, polyacrylamide (cationic, anionic, non-ionic), polymeric aluminium chloride, polymeric ferric aluminium chloride, ferrous sulphate, etc.

with china's resource-saving, environment-friendly society and the construction of the chinese government on the "energy saving and emission reduction" work to increase, adhere to environmental protection treatment to reduce pollution emissions, has become a long-term goal of china's environmental protection industry continued development. only the continuous development and use of new environmentally friendly water treatment agent technology and products, in order to continue to improve the competitiveness of enterprises and create the highest benefits. technological innovation is the driving force behind the sustainable development of water treatment chemicals, green is the future direction of the development of water treatment chemicals, the development of low phosphorus, non-nitrogen, biodegradable, non-toxic and non-hazardous, low-cost green water treatment chemicals suitable for china's environmental protection requirements, will become the direction of china's future development of water treatment chemicals. the development of a large number of environmental treatment projects in china provides a huge market demand and development opportunities.

q&a

scale inhibitors are generally classified according to the development history of scale inhibitor research and the functional groups in the scale inhibitor molecule, how are they classified?

scale inhibitors are divided into four main categories:

(1) natural polymeric scale inhibitors: common agents include tannin, cellulose, starch, lignin, chitosan, sodium humate, etc.
(2) phosphorus-containing polymeric scale inhibitors: these scale inhibitors are divided into inorganic phosphorus-containing polymeric scale inhibitors and organic phosphorus-containing polymeric scale inhibitors. the former common agents include sodium pyrophosphate, sodium tripolyphosphate and sodium hexametaphosphate. the latter commonly includes hydroxyethylenebisphosphonic acid, amino trimethylene phosphonic acid, ethylene diamine tetra-methylene phosphonic acid and polyamino polyether-based methylene phosphonic acid.
(3) copolymer scale inhibitors: common agents include acrylic copolymers, sulphonic acid copolymers, maleic anhydride copolymers and other non-phosphorus corrosion and scale inhibitors.
(4) new green scale inhibitors: common agents include polyepoxy succinic acid, polyaspartic acid.

what are the most common water treatment agents used for domestic drinking water?

the most common water treatment agents for drinking water are polyaluminium chloride, polymeric ferric sulphate, potassium permanganate and sodium hypochlorite. the main function of poly aluminium chloride is flocculation, and sodium hypochlorite is mainly disinfection and sterilisation.

the quality of water treatment agents available on the market varies, what support can noa provide to companies in this area?

noa can test the quality of detergent products to determine whether they can meet national standards, such as gb/t 22627-2014 "water treatment agent polyaluminium chloride", gb 19106-2013 "sodium hypochlorite", gb/t 1616-2014 "industrial hydrogen peroxide" and gb/t 20783-2006 "stable chlorine dioxide solution".

what is noa solution for water treatment agent products?

noa testing laboratory is equipped with high-precision instruments and equipment and professional technicians can provide technical services such as formulation optimization, raw material recommendation and process guidance to help enterprises achieve product performance improvement and production reduction, and can develop water treatment products such as biocides and emulsion breakers, and give different formulation systems of pharmaceutical products for different water quality.
