RTO fuel consumption high common problem cause and treatment methods. Infuencing factor Specific reason  Inspection method Optimization method 1 Low exhaust gas concentration  The exhaust gas is stable and its concentration is low The concentration of imported exhaust gas is continuously measured by mobile FID Where possible, increased thermal efficiency can reduce the fuel consumption

Influencing factor Specific reason Inspection method Solutions and optimizations 1 Low exhaust gas concentration The exhaust gas is stable and its concentration is low The concentration of imported exhaust gas is continuously measured by mobile FID If possible, increase the concentration multiple and reduce the post-concentration air volume 2 The exhaust gas is unstable, and

What are the common contaminants of RO membrane elements?The nature of contaminants and their fouling rate depend on feed water conditions. Fouling develops slowly, and if not addressed early, it can significantly damage membrane performance in a relatively short period. Regular system performance checks are a good way to detect fouling. Different contaminants affect membrane

Biological wastewater treatment is the process of treating pollutants in wastewater through the metabolic activities of microorganisms. It can be broadly classified into two categories: aerobic treatment and anaerobic treatment. Purpose and Importance of Biological Wastewater Treatment Role of Microorganisms in Biological Wastewater Treatment Microorganisms play three main roles in biological wastewater treatment:① Removal of

In the wastewater treatment process, the level of effluent COD (Chemical Oxygen Demand) is an important indicator of treatment effectiveness. COD reflects the degree of organic pollution in water, and high COD in the effluent indicates poor treatment performance and incomplete removal of organic matter. This not only has negative environmental impacts but can also

Industrial wastewater refers to the wastewater, sewage, and waste liquids generated during industrial production processes. It contains industrial raw materials, intermediate products, and pollutants that are lost with the water during production. The common industrial wastewaters and their characteristics are classified into several categories: 1. Coal-Fired Power Plant Desulfurization Wastewater Characteristics and Treatment Process Characteristics

Water hardness refers to the total concentration of calcium and magnesium ions in water. It is categorized into two types: 1. Chemical Softening (Using Agents): Chemical softening relies on the principle of chemical precipitation, where appropriate chemical agents are added to convert hardness-causing ions into insoluble salts, thereby removing them from water. Common agents include

Phenomena of Declined Settling Performance of Activated Sludge The main phenomena observed when the settling performance of activated sludge declines include: The decline in sludge settling performance is often accompanied by several of these phenomena. If this condition persists for a long time, the concentration of return sludge in the secondary clarifier will gradually decrease,

The salt separation crystallization processes commonly used in zero wastewater discharge include thermal salt separation, evaporation + freeze crystallization, and nanofiltration + separate evaporation crystallization. 01. Thermal Salt Separation This method utilizes the solubility differences of sodium sulfate (Na₂SO₄) and sodium chloride (NaCl) at different temperatures and carries out evaporation at varying temperatures. Sodium sulfate
