The wastewater with high COD content includes food COD wastewater, paper making COD wastewater, oil refinery COD wastewater, landfill leachate COD wastewater, emulsion COD wastewater, chemical industry COD wastewater, pharmaceutical COD wastewater, charcoal COD wastewater, coking COD wastewater, coal tar COD wastewater and so on.

There are many kinds of sewage treatment methods with high COD content, first of all, we should do a good job of sewage pretreatment, through the physical grid or separator, remove the large particles of organic COD suspended matter, and then use chemical flocculation or oxidation method to remove most of the organic COD, and finally, through biological treatment method to make the sewage COD standard discharge.

In addition, for particularly high COD sewage, COD of hundreds of thousands of sewage, this sewage can be thoroughly treated by evaporation or incineration.

Global Trade Resumption and Shipping Industry Challenges: An Overview

Global Trade Resumption and Shipping Industry Challenges: An Overview
Time of issue : 2024-11-22 11:14:22
As global trade activities gradually recover, the shipping industry is experiencing unprecedented shipping space shortages. Concurrently, shipping prices are showing significant upward trends, posing a crisis and challenge to the global supply chain. Crisis in the Global Supply Chain, Skyrocketing Shipping Costs This year, influenced by multiple factors such as escalating geopolitical tensions and regional conflicts, the global supply chain has fallen into a severe crisis. On one hand, the conflict in the Red Sea has affected the navigation through the Suez Canal. In response to blocked routes, a large amount of cargo has chosen to detour around the Cape of Good Hope. This not only significantly increased transportation costs and delayed delivery times but also increased carbon emissions. For instance, for a large container ship (with a capacity of 20,000-24,000 TEU) on the Far East to Europe route, if it detours around Africa, the additional emission costs calculated by the EU Emissions Trading System (ETS) for each voyage can reach as high as $400,000. To cope with the increase in transportation costs, many shipping companies have adjusted their freight rates, leading to a rise in shipping prices. On the other hand, the congestion and strikes at some European and American ports have resulted in large-scale sailing cancellations for European and American routes. According to Drewry’s data on canceled voyages, from September 30 to November 3, 2024, 100 voyages were announced canceled on the main east-west routes—trans-Pacific, trans-Atlantic, and Asia-Northern Europe and Mediterranean routes. The total number of canceled voyages accounted for 14% of the planned 693 voyages. The increase in the proportion of canceled voyages and the undiminished transportation demand led to severe overbooking and cargo rollovers starting in mid- to late October. According to the “China Export Container Transportation Market Weekly Report” released by the Shanghai Shipping Exchange on November 9, overbooking occurred on routes to North America, South America, Europe, and Southeast Asia at the end of October, with some routes extending to November. This situation also led to rising shipping prices. The report showed that on November 8, the market freight rates (including ocean freight and ocean surcharges) from Shanghai to the basic ports of Europe and the Mediterranean were $2,541/TEU and $3,055/TEU, respectively, up 4.1% and 5.1% from the previous period. The Shanghai Shipping Exchange’s Shanghai (SCFI) on November 8 was 2,331.58 points, up 1.2% from the previous period, marking the third consecutive week of increase, approximately 13% higher than the low on October 18. The skyrocketing shipping prices have not only brought tremendous pressure to the global logistics and supply chain but also further complicated the global transportation and trade network. High Freight Rates Likely to Persist Until the End of the Year To cope with market changes and alleviate the pressure of insufficient capacity, ensuring the stability and sustainability of transportation services, several globally renowned shipping companies such as Hapag-Lloyd, Hyundai Merchant Marine (HMM), and Maersk have recently announced new freight rate adjustment plans and notices for peak season surcharges. Hapag-Lloyd announced on October 30 that it would increase the FAK rates on the Far East to Europe route, effective from November 15, 2024. Hyundai Merchant Marine (HMM) announced in a customer notice that, starting from December 1, 2024, it will implement GRI (General Rate Increase) for all services from origin to the United States, Canada, and Mexico. Maersk recently announced that it will impose peak season surcharges (PSS) on routes to Australia, Papua New Guinea, Solomon Islands, and other destinations. At the same time, it will impose peak season surcharges on routes to Africa to address the ongoing tensions in the global shipping market. By adjusting freight rates and imposing surcharges, a certain balance between supply and demand can be achieved, ensuring the normal operation of shipping businesses, but it also unintentionally pushes up the price of the entire maritime market. At the same time, affected by festivals such as Thanksgiving and Christmas, the transportation demand on the European route remains high, which will continue to drive up the spot market freight rates. Therefore, shipping prices may continue to rise before the end of the year. Whether future freight rates can significantly fall mainly depends on the trends of geopolitical conflicts such as the Red Sea crisis and international situations. The increase in shipping prices is undoubtedly a good thing for shipping companies, but for enterprises, it will not only increase their transportation costs but may also affect the efficiency and cost structure of global trade activities. Especially for manufacturing and retail industries that rely on multinational supply cha

Water treatment, to put it bluntly, is a series of technologies and products designed to improve water quality and ensure the safe use of water resources. These water treatment products are very important to protect our public health, protect the environment, and ensure the smooth operation of industrial production. They are like magical magicians, through physical, chemical or biological means, the impurities in the water, bacteria these bad things are removed, to provide us with clean and safe water. When it comes to water treatment, calcium hypochlorite, the disinfectant, does not need to be mentioned, but it does need to be said a few words. It is particularly strong, can quickly decompose into hypochlorous acid, sterilization and disinfection that is an absolute, to control the growth of bacteria in the water, viruses, these microorganisms, it is indispensable. However, water treatment is not a single product can be done, a variety of technologies and products together, in order to achieve the best results. From the process point of view, water treatment is like water to do a whole body SPA, there are pre-treatment, main treatment, post-treatment steps. Each step has its own little trick to ensure that the water quality is up to standard step by step. Pretreatment is like a preliminary clean water, screen filtration, coagulation and precipitation of these means, the large particles of impurities are removed; The main treatment is like deep cleaning, biological treatment, chemical oxidation (such as the disinfection of calcium hypochlorite), these methods to improve the water quality; Post-treatment is like the final delicate care, activated carbon adsorption, membrane filtration, the residual trace pollutants are removed. In general, water treatment products and technologies contribute greatly to ensuring the safe and sustainable use of water resources. As long as we choose and apply these products scientifically and reasonably, we can effectively deal with the challenges facing water resources and ensure the healthy development of our society.
