The role of industrial glucose in wastewater: Why add industrial glucose in wastewater treatment? During the commissioning of wastewater treatment, adding industrial glucose and other substances is to provide a carbon source, which helps in better bacterial cultivation, improves the biodegradability of wastewater, and effectively enhances the affinity of sludge. It works faster than urea. If the COD and BOD in the operating system are insufficient to support the growth and reproduction of bacteria, additional dosing is required to prevent sludge aging and reduced biological activity.
2. Industrial-grade glucose is used in the leather industry for processing leather, such as sole leather and suitcase leather, to increase its softness and serve as a reducing agent for chrome tanning.
3. Industrial glucose is used as a steel surface cleaning agent: When steel surfaces require plating, such as tin plating, chromium plating, nickel plating, or for special purposes like manufacturing tinplate, galvanized sheets, or chrome-plated surfaces (electroplating), the steel坯 surface must be thoroughly cleaned to ensure strong adhesion of the plating material. Adding sodium gluconate to the cleaning agent achieves ideal results.
4. Industrial glucose can be used as a cement admixture: Adding a certain amount of gluconic acid to cement increases the plasticity and strength of concrete and has a retarding effect, delaying the initial and final setting times of concrete. For example, adding 0.15% gluconic acid can extend the initial setting time of concrete by more than 10 times, prolonging the plastic time from a few hours to several days without affecting its strength.
5. Industrial glucose can be used in various industrial fields such as electroplating and film manufacturing.

6. As a specialized cleaning agent for glass bottles: Using sodium gluconate as the main ingredient in glass bottle cleaning agents can address common issues such as insufficient cleaning power, clogging of nozzles and pipelines in bottle washers, inadequate removal of bottle labels and rust on bottle necks, unsatisfactory safety due to微量殘留物 (e.g., phosphate residues), and harmful discharge of washing water.

Reference materials
Glucose dosing is higher in winter because lower temperatures reduce microbial reproduction rates.
Properties and advantages of industrial glucose:

1. Fast hydrolysis speed and weak hydration. Forms dense flocs with rapid settling速度. Less affected by water temperature changes and meets the requirements for generating shear force during flow.

2. Solid product is pure white, white powder, highly soluble in water.

3. Effectively removes aluminum ions from source water and residual free aluminum ions after aluminum salt coagulation.

4. Wide range of applications, including domestic drinking water, industrial water, domestic water, domestic wastewater, and industrial wastewater treatment.

5. Low dosage, effective treatment, and saves 10-20% costs compared to other coagulants.

6. Usage methods, packaging purposes, and precautions are basically the same as those of [polyaluminum chloride].

Usage methods of industrial glucose:

1. Depending on the raw water conditions, conduct small-scale tests beforehand to determine the optimal dosage.

2. For production use: solid-to-water ratio ≈ 1/5. First mix and dissolve, then dilute with water to a 2~3% solution.

Application scope of industrial glucose:

Used in domestic drinking water, industrial water, domestic water, domestic wastewater, and industrial wastewater treatment. Industrial glucose has significant effects on the purification of domestic drinking water and various industrial waters.

During the commissioning of wastewater treatment, adding industrial glucose and other substances is to provide a carbon source, which helps in better bacterial cultivation and improves the biodegradability of wastewater. As a nutrient source for sludge in wastewater treatment, it works faster than urea. If the COD and BOD in the operating system are insufficient to support the growth and reproduction of bacteria, additional dosing is required to prevent sludge aging and reduced biological activity.

During the operation of a biochemical tank, if microorganisms are impacted by負(fù)荷 (water volume, concentration), the COD removal rate may suddenly drop, and in severe cases, sludge may detach from the biological filler, making the effluent turbid. In such cases, immediately stop the inflow and add specialized glucose for wastewater treatment to the biochemical tank to reduce the sludge load. Once the sedimentation performance of the sludge recovers, adopt a rapid proliferation method for sludge acclimation by adding domestic wastewater, waste alcohol, or cooked wet paste made from dry flour to the biochemical tank. Add specialized glucose for wastewater treatment, and after 2-3 days, start inflow and gradually increase the inflow volume until the microorganisms return to normal.

Industrial glucose is generally added to anaerobic and aerobic systems. For anaerobic systems, the main considerations are the degree of acidification, influent COD, and indicators such as pH and VFA. COD generally does not need consideration as it can be adjusted in the equalization tank (comprehensive調(diào)節(jié)池). When the pH is high and acidification is insufficient, glucose is usually added to promote acidification. The dosage depends on the influent water quality. It is typically added before the biochemical tank, dissolved in water first. For aerobic systems, it is not needed if BOD is sufficient. If BOD is lacking, it should be added to prevent nitrification.
