In daily water treatment, public environment disinfection and sterilization, food processing, aquaculture water body maintenance and other practical work, unpleasant odor, pipeline scaling and blockage, and water quality turbidity not up to standard are problems that we often encounter. Shandong Huashi Pharmaceutical has been deeply involved in chlorine dioxide disinfection for more than 40 years since its establishment in 1983. Its subsidiary, Xiuba Chlorine Dioxide, has become the preferred product for solving odors, cleaning pipeline dirt, and purifying water quality due to its high purity, good activation effect, safe and environmentally friendly use. Based on our years of on-site practical experience and professional technical accumulation, today we have compiled the most frequently asked and concerned questions by users, and explained them clearly to everyone at once.

1、 FAQ on odor treatment
What odors can chlorine dioxide remove? What is the actual effect?
Chlorine dioxide can not only disinfect and kill bacteria, but also decompose substances that produce odors at the root. The odor of hydrogen sulfide, the smell of decay and deterioration, the fishy smell of aquaculture, the moldy smell of warehouses and cold storage, and the odor emitted by sewage can all be effectively removed. It does not use fragrance to mask odors, but directly destroys the structure of odor molecules, and there will be no secondary odor residue after treatment. In practical application, we found that Xiuba Chlorine Dioxide has a stable effect on most common obstinate odor removal, and can meet the daily disinfection and sterilization and odor removal needs.
2. Which product and how much amount is suitable for removing odors from domestic and industrial wastewater?
For daily treatment of sewage odor, priority should be given to using Xiuba chlorine dioxide powder or effervescent tablets, which are convenient and cost-effective to use. In general, 10 to 20 grams of sewage per ton is sufficient; If the odor is particularly strong, such as long-term storage of sewage or high organic content, it can be appropriately increased to 20 to 30 grams per ton. Put it evenly and let it sit for about half an hour, and you can clearly feel that the odor has decreased or even disappeared.
How to use public toilets, garbage stations and other places to remove odors more safely?
These types of places have frequent personnel interactions and high safety requirements. You can dissolve Xiuba chlorine dioxide effervescent tablets in a ratio of 500 milliliters of water per tablet, put them into a spray bottle for direct spraying, or slowly put them in a slow-release box to take effect. Easy to operate, no pungent odor, relatively mild to the human body, can suppress odors, and also play a basic disinfection role, suitable for long-term daily maintenance.
Does using chlorine dioxide to remove odors in food factory workshops and cold storage meet hygiene and safety requirements?
Shandong Huashi Pharmaceutical's Xiuba chlorine dioxide products have complete qualifications such as water related permits and third-party testing reports, and meet the disinfection and hygiene standards for food related scenarios. Used for deodorization in the air, floors, cold storage and other environments of food factories and workshops. After normal use, the residue is extremely low and will not affect the quality of food. It also complies with relevant hygiene regulations, and everyone can use it with confidence.
2、 FAQ on pipeline descaling
Can chlorine dioxide clean the scale and biofilm in pipelines?
The answer is yes. Chlorine dioxide has an oxidizing effect, which can kill bacteria and algae in pipelines and reduce the formation of biofilms; On the other hand, it can slowly decompose the sticky mud and dirt deposits on the inner wall of the pipeline, which can help to clear the pipeline. Adhering to standardized use can also to some extent inhibit the recurrence of new dirt.
Is it safe to use chlorine dioxide to remove scale from drinking water pipelines and secondary water supply pipelines in residential areas?
Xiuba chlorine dioxide has passed the relevant national water safety certification. When used for descaling drinking water pipelines, as long as the recommended dosage is strictly followed, it will not produce harmful substance residues. It is also gentle on commonly used metal and plastic pipelines and will not cause significant corrosion, fully meeting the requirements of drinking water hygiene.
How to operate pipeline descaling specifically?
Let me share a simple and practical step with you: the first step is to close the inlet valve of the pipeline and drain some of the accumulated water; Step 2: Prepare a disinfectant solution by adding 15 to 25 grams of Xiuba chlorine dioxide per ton of water; Step three, inject the prepared liquid into the pipeline and soak for 2 to 4 hours; Step four, empty the waste liquid in the pipeline, rinse it with clean water once or twice, and it can be used normally.
4. Industrial sewage pipelines are prone to long-term scaling. How often is it appropriate to treat them?
Based on our experience serving a large number of clients, it is recommended to treat ordinary industrial sewage pipelines every one to two months; If the pipeline transports high impurity and high pollution sewage for a long time and the scaling situation is severe, it can be shortened to once a month for treatment. Regularly adding a small amount of low concentration chlorine dioxide can keep the pipeline unobstructed for a long time and reduce blockage problems.
3、 FAQ on Water Purification
What common problems can be solved by using chlorine dioxide to purify water quality?
The role of chlorine dioxide in purifying water quality is comprehensive, as it can quickly kill bacteria, viruses, algae and other microorganisms in water, as well as oxidize and decompose some heavy metal ions, organic matter and suspended impurities. Conditions such as turbidity, yellowing, greenness, and slight odor in water can be significantly improved, making the water clearer and safer.
What is the standard dosage for purifying tap water and rural drinking water?
Disinfection and purification of daily drinking water require minimal usage, with 0.5 to 1 gram per ton of water being sufficient; If the water quality of the source is poor, the turbidity is high, and there are many microorganisms, it can be appropriately increased to 1 to 2 grams per ton of water. After 30 minutes of contact reaction, the water quality can basically meet the safety standards for daily use.
3. Will using chlorine dioxide in fish tanks and landscape pools harm fish, shrimp, and aquatic plants?
As long as the dosage is strictly controlled, it is safe. Xiuba Chlorine Dioxide has optimized its formula for water purification, with one effervescent tablet added to every 300 liters of water in the fish tank; Landscape water tanks are designed to produce 1 to 3 grams of water per ton, which can purify water quality, prevent common diseases of fish and shrimp, and not have adverse effects on aquatic animals and plants. Many fish enthusiasts and landscape maintenance personnel use them.
Can the purification of aquaculture water bodies such as fish ponds and shrimp ponds improve the blackening and odor of the bottom?
Absolutely possible. The accumulation of organic matter, ammonia nitrogen, and nitrite in the sediment of aquaculture ponds is the main reason for the deterioration of sediment and water quality. Chlorine dioxide can oxidize and decompose these harmful substances, reduce oxygen consumption of sediment, improve the problem of black and odorous sediment, purify the upper water layer, indirectly improve the dissolved oxygen status of water, and greatly help stabilize aquaculture production.
5. After the water purification medication is administered, how long can it reach the usage standard?
Under normal circumstances, after adding Xiuba chlorine dioxide and allowing it to react for 30 minutes, the basic disinfection and purification process can be completed. It is recommended to let the drinking water sit for 30 minutes before use; Non drinking water such as sewage and landscape water can also achieve corresponding purification effects after 30 minutes.
4、 Comprehensive Practical FAQ
1. Which dosage form of Xiuba chlorine dioxide is most convenient for dealing with odors, descaling, and water purification?
Suggestions for different scenarios: large-scale sewage treatment, large-scale pond purification, using powder is more cost-effective and convenient to deploy; Small area environment disinfection and sterilization, household pipeline cleaning, fish tank use, select effervescent tablets, instant, good metering, not easy to make mistakes; In scenarios such as industrial pipelines and centralized water supply systems with automatic dosing equipment, liquid dosage forms are used for better adaptability.
What are the things to pay attention to when using chlorine dioxide in daily life?
