CHARACTERISTICS AND EFFECTS OF RUBBER WASTEWATER ON THE ENVIRONMENT
Rubber products have become an indispensable part of modern life. Not only is it used in household products such as blankets, sheets, pillows, and mattresses, but rubber is also widely used in many different fields. For example, in the shipbuilding industry, rubber is used to make soundproofing and anti-vibration parts. In medicine, rubber is used to create medical devices such as condoms, medical tape, and anti-pressure cushions. Rubber is also used in the auto industry to make parts such as transmission parts, suspension parts and fuel lines. With such diverse applications, the importance of rubber products in our daily lives cannot be denied.
With the increasing necessity of rubber products, it also leads to an increase in the amount of rubber wastewater that needs to be treated in the process of producing raw rubber, processing rubber latex, and producing finished products from rubber. su. Rubber wastewater is one of the sources of serious environmental pollution. During the rubber production process, water is used to wash and soften rubber, creating wastewater containing many pollutants such as nitrogen and ammonium.
Rubber wastewater has the following basic characteristics:
- The pH concentration ranges from 4.2 - 5.2.
- Making the amount of volatile solid waste in water account for up to 90%.
- Wastewater contains high levels of Ammonium and Nitrogen.
- Contains many proteins that easily decompose and create odors. At the same time, many other gases are created such as: H2S, NH3, CH3COOH...
- Phosphorus content and BOD, COD, TSS concentrations are high.
Rubber wastewater contains many organic compounds that easily decompose, causing odors. At the same time, the concentration of organic matter in wastewater is very high, making the water cloudy and taking a long time to decompose. If not treated thoroughly, it will cause lasting pollution affecting water sources and the lives of surrounding people.
To minimize negative impacts on the environment, using probiotics to treat rubber wastewater has become an effective solution. In this article, we will learn about the uses of probiotics to treat Nitrogen and Ammonium in rubber wastewater.
AMMONIUM AND NITROGEN IN RUBBER WASTEWATER
Ammonium and Nitrogen are two serious environmental pollutants that cause health problems and damage aquatic ecosystems. Ammonium is the valence state of Nitrogen. If ammonium exceeds the allowable standard content, it will be converted into Nitrite and Nitrate, which are carcinogens and other dangerous pathogens.
In addition, ammonium and trace elements in water are also favorable conditions for the growth of bacteria. At the same time, they are also a rich source of nutrients for the growth and development of algae, causing cloudy water.
In addition to polluting and harming the water environment, ammonium also interferes with the water treatment process. It affects the effectiveness of chlorination, reducing its ability to kill bacteria and other pathogens.
EFFECTIVE TREATMENT OF RUBBER WASTEWATER USING MICROBIOLOGICAL Yeast TO TREAT NITO AND AMONIUM
By using probiotics to treat wastewater - The purpose of this method is to use microbial strains to decompose organic pollutants. The probiotic treatment process is carried out through two digestion tanks, including an anaerobic tank and an aerobic tank.
In an anaerobic tank, when wastewater comes into contact with sludge, a hydrolysis reaction will occur, acidifying and creating methane.
Next, wastewater is transferred to the Aerotank tank. Here, groups of aerobic microorganisms need to use oxygen to decompose organic compounds. This process helps remove pollutants such as BOD, Nitrogen...
The system often encounters problems when the factory increases production output, leading to an overload of Ammonium and Nitrogen, causing load shock and killing microorganisms, leading to untreated wastewater. Adding probiotic products that treat Nitrogen and Ammonium is necessary to restore the system. When added to wastewater, microorganisms will perform the nitrification and denitrification process of two aerobic bacteria Nitrosomonas and Nitrobacter.
Stage 1: Nitrosomonas bacteria convert Ammonia (NH3, NH4) into Nitrite (NO2)
Phase 2: Then, Nitrobacter bacteria will convert Nitrite (NO2) into Nitrate (NO3-)

Probiotics that process Nitrogen and Ammonium – EnviClean AMO is a product of a mixture of specially isolated microorganisms to remove Nitrogen, Ammonia and odor-causing organic-rich impurities from wastewater. The combination of at least 7 strains of Bacillus, Nitrosomonas and Nitrobacter helps the biodegradation process take place quickly, achieving optimal treatment efficiency for the system.
Probiotics that process Nitrogen and Ammonium – EnviClean AMO Easily adaptable to different environmental conditions, they break down NH4 into its core elements, effectively reducing odor and reducing ammonia concentration in wastewater.
Benefits of biological products for wastewater treatment - EnviClean AMO:
- Enhance the nitrification process taking place in the aerobic tank and the denitrification process in the anoxic tank.
- Improve and restore the system effectively.
- Reduces ammonia odor in wastewater treatment systems.
- Reduce costs: operations and labor.
- Reduce Nitrogen, Ammonium, BOD, COD, TSS
- Overcome the phenomenon of dead and shocked microorganisms
- Overcome the problem of foaming and sludge not settling in the aerobic tank
How to use probiotics to treat Nitrogen and Ammonium
Dosage is based on optimization level, pollutant load, waste source properties and different treatment facilities.
The dosage used is based on the level of optimization, pollutant load, nature of the waste source and the work
different processing.
Standard dosage is as follows:
| Lưu lượng (m3) | First month | 2nd month onwards |
| 0 – 10 m3 | 2 Pounds/Week | 1 Pound/Week |
| < 50 m3 | 4 Pounds/Week | 2 Pounds/Week |
| < 100 m3 | 6 Pounds/Week | 3 Pounds/Week |
| < 500 m3 | 8 Pounds/Week | 4 Pounds/Week |
| < 1000 m3 | 12 Pounds/Week | 6 Pounds/Week |
| < 3000 m3 | 20 Pounds/Week | 10 Pounds/Week |
Recommended: To achieve optimal results, you should add microorganisms to the water and aerate it for 24-36 hours before putting it into the system.
