Information

There are two types of biological treatment technologies that are most widely used in wastewater treatment projects: one is called activated sludge method, and the other is called biofilm method. The activated sludge process is a form of aerobic wastewater treatment performed by the biochemical metabolism of suspended biological groups. Microorganisms can form bacteria micelles with a large surface area during the growth and reproduction process, which can flocculate and absorb a large amount of suspended colloidal or dissolved pollutants in wastewater, and absorb these substances into the cell body. Complete oxidation of these substances releases energy, CO2 and H2O. The sludge concentration of activated sludge method is generally 4g/L. In the biofilm method, microorganisms adhere to the surface of the filler to form a colloid-linked biofilm. Biofilms generally have a fluffy flocculent structure with many micropores and a large surface area, and have a strong adsorption effect, which is conducive to the further decomposition and utilization of these adsorbed organic substances by microorganisms. During the treatment process, the flow of water and the agitation of the air make the surface of the biofilm constantly contact with the water, the organic pollutants and dissolved oxygen in the wastewater are adsorbed by the biofilm, and the microorganisms on the biofilm continuously decompose these organic substances, and in the oxidative decomposition At the same time as the organic matter, the biofilm itself is constantly metabolized, and the aging biofilm falls off and is taken out of the biological treatment facility by the treated effluent and separated from the water in the sedimentation tank. The sludge concentration of biofilm method is generally 6-8g/L. In order to increase the sludge concentration and then improve the treatment efficiency, the activated sludge method can be combined with the biofilm method, that is, the filler is added to the activated sludge tank. Known as a compound bioreactor, it has a very high sludge concentration, generally around 14g/L.

Difference between calcium hypochlorite and bleaching powder

Difference between calcium hypochlorite and bleaching powder

1. What is Calcium hypochlorite? The main components of bleaching powder commonly used in aquaculture are calcium chloride and calcium hypochlorite. Among them: the effective component of bleaching powder that plays a role in disinfection is calcium hypochlorite [ca (CLO) 2], and calcium chloride is a chemical substance that will obviously absorb moisture. Due to the existence of calcium chloride in bleaching powder, the available chlorine in bleaching powder is easily affected and reduced. Because calcium hypochlorite is the essence of bleaching powder, calcium hypochlorite is also called bleaching powder essence in the market. Compared with bleaching powder, it is pure calcium hypochlorite essence and does not contain calcium chloride and other hygroscopic substances. The chlorine content is about 68%, which is significantly higher than the effective chlorine content of the newly produced non damped bleaching powder. Generally, the disinfection dose is only 0.1~0.2ppm. In aquaculture and other industries that need disinfection and oxidation, disinfectants that dissolve in water and produce hypochlorite are generally referred to as chlorine containing disinfectants. The germicidal efficacy of chlorine containing disinfectants is closely related to the amount of effective chlorine they contain. The higher the effective chlorine, the stronger the disinfection and oxidation capacity. 2. Comparison of advantages and disadvantages between bleaching powder and calcium hypochlorite Advantages of bleach: It is cheap and has obvious effect on general pathogenic microorganisms. Disadvantages of bleach: Due to the strong water absorption of calcium chloride contained in bleaching powder, it is easy to decompose when exposed to light, water, heat, etc., and is not resistant to storage. Especially in humid areas, the available chlorine of bleaching powder will decrease exponentially in about a month. Even lead to the loss of proper disinfection effect. The principle of bleaching powder deterioration: Calcium chloride in bleaching powder absorbs water and makes calcium hypochlorite in bleaching powder generate hypochlorite.   3. Hypochlorous acid will decompose into hydrogen chloride and oxygen under light conditions, thus losing effective chlorine. Advantages of calcium hypochlorite: contains very little hygroscopic calcium chloride, so calcium hypochlorite is relatively stable and resistant to storage and transportation (which is very important to ensure the disinfection effect). Compared with bleaching powder, the available chlorine of calcium hypochlorite is stable and high, which has obvious effect on general pathogenic microorganisms. The amount of use in disinfection is small, which reduces the amount of labor. Disadvantages of calcium hypochlorite: Since calcium hypochlorite contains a large amount of effective chlorine, protective measures need to be taken during operation.

Market Overview It is estimated to reach USD 1,808.11 million by 2031, growing at a CAGR of 11.13% over the forecast period (2023–2031). Market growth is anticipated to be driven by the rising demand for calcium hypochlorite in the coming years, driven by the rising usage of hygiene products to prevent water-borne diseases like cholera and typhoid.   Calcium hypochlorite is an inorganic compound utilized as a component in chlorine powder and bleaching powder, among other applications. It undergoes gradual decomposition in humid air and emits a potent chlorine odor. Calcium hypochlorite overuse can be harmful and irritate the skin. It has extensive applications in the disinfection of swimming pools, water purification, and bleaching textiles and paper. Calcium hypochlorite must be stored away from organic materials such as cloth, wood, and petroleum products since it can cause an explosion or fire when reacted.   Calcium hypochlorite is mainly used to disinfect drinking water and public swimming pools. The surging usage of calcium hypochlorite in spas, hot tub water, and swimming pools is anticipated to positively impact the growth of the calcium hypochlorite market worldwide. It is used as an oxidizer for decontaminating mustard gas and as a pesticide for insects, especially caterpillars. Calcium hypochlorite is also used to kill bacteria in different food products. It is utilized to sanitize the surfaces of different equipment and utensils. In households, calcium hypochlorite is commonly used in algaecides, bathroom cleaners, herbicides, household disinfectant sprays, laundry detergents, etc.

Calcium hypochlorite is a white, concentrated chemical sold as a powder, as crystals and in tablets. All are used to disinfect and sanitize drinking water and swimming pool water. When combined with water, calcium hypochlorite releases oxygen and a high concentration of chlorine molecules. Chlorine is an effective way to kill bacterial and fungal populations in water sources, and, compared with other sources of chlorine for water purification, it is easier and safer to use. However, there are some downsides to be aware of in calcium hypochlorite use. Cost Effectiveness One of the primary benefits of calcium hypochlorite is that a relatively small amount of the chemical can successfully disinfect large amounts of water, making it one of the most cost-effective choices in water sanitation. According to Survivaltopics.com, a site devoted to providing readers information about surviving outdoors and during emergency situations, a 1-lb. bag of calcium hypochlorite in granular form can treat up to 10,000 gallons of water. Ease of Use Although using chlorine as a water disinfectant is generally simple and efficient, calcium hypochlorite is preferred over the other common forms of chlorine water treatment–chlorine gas and liquid bleach (also known as sodium hypochlorite)–because it is more stable, requires less equipment to use and is easier to transport. Chlorine gas is highly effective but must be handled with extreme care because of its hazardous, corrosive nature. Liquid bleach is most useful when treating only small amounts of water. By contrast, calcium hypochlorite is safer to handle than chlorine gas and can be used on much larger volumes of water than bleach. Length of Storage Another benefit of calcium hypochlorite is that it can be stored for long periods of time without any of its disinfectant ability diminishing. Other forms of chlorine, such as liquid bleach, degrade in a matter of months. In order to be certain that your bleach has the optimal level of chlorine, a representative of Clorox says, you should change your supply of bleach every three months.
