The role of calcium chloride in wastewater treatment

28 Jun,2024

The role of calcium chloride in wastewater treatment Calcium chloride plays an important role in sewage treatment, and its role is mainly reflected in the following aspects: 1. PH neutralization: Calcium chloride aqueous solution is acidic, so it can be used to neutralize sewage, pre adjust the acidic sewage pipeline network, thereby extending the service life of the pipeline network and saving investment costs. During this process, calcium chloride can effectively adjust the acidity and alkalinity of wastewater, providing suitable environmental conditions for subsequent wastewater treatment. 2. Sterilization and disinfection: Calcium chloride is a typical ionic halide, and its chloride ions dissolved in water have a bactericidal and disinfection effect. This property enables calcium chloride to effectively kill harmful bacteria in water, reduce water toxicity, and improve the safety of water quality. 3. Ion exchange: In the wastewater treatment process, the calcium ions in calcium chloride can replace the metal cations in the effluent, especially in the wastewater treatment process containing metal cations. This displacement effect can effectively remove toxic and harmful substances from water, reduce the damage of metal cations to the biochemical stage, and thus play a crucial pre-treatment role. 4. Filter aid effect: Calcium chloride can also be used as a filter aid in wastewater treatment, helping to improve filtration efficiency and further purify water quality. 5. Multi functional sewage treatment agent: Calcium chloride can be used as a common defluorinator, dephosphorizer, decolorizer, degreaser, etc. in sewage treatment. As a fundamental inorganic salt water treatment agent, calcium chloride combined with other efficient sewage treatment agents can not only reduce the cost of sewage treatment, but also achieve standard discharge of sewage. In summary, calcium chloride has various functions in wastewater treatment, including neutralization, sterilization, displacement, filtration assistance, and serving as a multifunctional wastewater treatment agent. These effects have made calcium chloride widely used in the field of sewage treatment, making important contributions to improving water quality and protecting the environment.

Domestic soda ash market price increases

23 Apr,2024

Today, the domestic soda ash market price has increased by 50-150 yuan/ton. As of now, the price of light soda ash in southwest China is 1900-2000 yuan/ton, and the price of heavy soda ash is 2050-2150 yuan/ton; in central China, the price of light soda ash is 2050-2150 yuan/ton. The price is 1,900-2,100 yuan/ton, and the price of heavy soda ash is 2,000-2,200 yuan/ton; the price of soda ash is low, and alkali plants in some areas have reduced production. Due to the increase in low-price purchases in the downstream market, market procurement enthusiasm has increased, and some companies have Orders increased, manufacturers destocked inventories, and soda ash prices rose steadily today.  Futures dynamics According to Boduoduo data, the opening price of the main soda ash contract SA2409 on April 22 was 2,100 yuan/ton, and finally closed at 2,150 yuan/ton, with an intraday increase of +2.28%. The highest intraday price was 2,186 yuan/ton, and the lowest was 2,085 yuan/ton. The total positions were 794,376 lots, +46,110 lots month-on-month. Today's main soda ash contract continued to rise as a whole. Supply-side maintenance has continued recently, the dynamic supply-demand relationship in the second quarter is still tight, and photovoltaic growth expectations are strong. Until the overall supply reduction and demand increase expectations in the distant month cannot be falsified, soda ash prices may remain strong. In the short term, we need to be wary of a correction in the overall macro environment and possible negative feedback from selling pressure in the midstream of the market.  Forecast for the market outlook: Soda ash prices are low, downstream companies are in an increased mood to stock up, soda ash plants have more pending orders, manufacturers are destocking more, some soda plants have more orders, the supply is tight, companies have closed orders and will not quote prices for the time being, so soda ash prices are expected to rise in a narrow range.

Strong wait-and-see sentiment in the soda ash market, with low inventory!

25 Mar,2024

This week, the construction of the soda ash industry started at about 88.8%, a decrease of 1.12% compared to last week. According to statistics, the production of soda ash manufacturers this week is about 139000 tons. This week, the total inventory of domestic soda ash manufacturers was 795000 tons, compared to around 800000 tons last week, a decrease of 15000 tons compared to the previous week, a decrease of 1.91%. As of now, the domestic price of light soda ash is between 1800-2000 yuan/ton, and the price of heavy soda ash is between 2000-2200 yuan/ton; This week, some companies in the soda ash market have slightly reduced production, but overall production remains high; The supply and demand in the soda ash market are basically balanced, with some manufacturers reducing their inventory in a narrow range, and some enterprises still maintaining high levels of inventory; The downstream market demand is relatively stable, and most enterprises have some orders on hand. The overall inventory pressure is not high, and the market is mainly subject to narrow adjustments. In terms of futures, the overall price of soda ash fluctuated narrowly with the market environment this week. Although there has been a slight reduction in the current supply side, the overall situation is still at a high level with narrow fluctuations, and the supply-demand relationship has not yet changed. However, there is still a phenomenon of upstream price appreciation in the future, and it is not ruled out that there will be more unexpected production reduction behaviors. The support for cost reduction is still strong, and with relatively stable spot market quotations, it is difficult to see strong driving breakthroughs in the upward and downward space of futures prices. Next week's forecast: Individual soda ash companies may undergo maintenance next week, and they will deliver orders in hand; In the near future, the market production and sales have been basically balanced, and downstream enterprises are maintaining essential procurement. The soda ash market is expected to operate steadily, and the supply and demand sides are playing a game.

In the past month, the price of soda ash has risen like a rocket, and the supply of goods is also very tight, which has been rare since 2021. When asked about the current selling price level, in North China, light alkali is currently in the range of 3150-3200 yuan/ton (including tax exit), while heavy alkali is around 3350 yuan/ton (including tax exit); In recent days, the upward trend has significantly slowed down, and although it is still in a best-selling state, compared to the panic of competing for goods before, everyone's mentality has clearly relaxed, and perhaps they have become accustomed to this high price level.
