Details Description

For food industry wastewater, Oasis provides food wastewater recycling system solutions and food industry wastewater recycling solutions. The system adopts a combination of anaerobic hydrolysis acidification and biological filtration process, which removes impurities such as colloidal proteins and polysaccharides in the soaking solution through ultrafiltration system, removes more than 95% of the salt content through electrodialysis, and the feed solution desalinated by electrodialysis enters the reverse osmosis system for concentration. The product concentration in the concentrated solution is increased by three times, and the permeate water is returned to the production line as high-quality process water for high-value recycling.

The food industry, including the beverage industry, is a major water consumer. Due to the wide range of raw materials and various types of products, the amount and quality of wastewater discharged vary greatly. The main pollutants in wastewater include solid substances, oils, proteins, starch, colloidal substances, acids, alkalis, salts, sugars, mud, sand, pathogenic bacteria, etc. The characteristics of this type of wastewater are high organic matter and suspended solids content, which are prone to decay. Its hazards mainly include eutrophication of the water body, causing the death of aquatic animals and fish, and promoting the production of foul odors from organic matter deposited at the bottom of the water, polluting the environment. With the continuous development of food production, the amount of wastewater discharged is increasing, polluting the surrounding environment and damaging the corporate image. Food companies hope to find an economical and efficient method for treating food wastewater to achieve sustainable development and protect the environment.

★ Characteristics of Food Wastewater Recovery System

1. High removal rate

This process fully utilizes the strong hydrolysis ability of anaerobic microorganisms and the strong oxidation ability of attached growth aerobic microorganisms, achieving organic coupling of the two main functions of microorganisms and efficient integration of technology. It has a higher organic matter removal efficiency than conventional treatment processes and can treat organic wastewater with high suspended solids content.

2. Energy saving and efficient

The process structure is simple, the infrastructure investment cost is low, the flexibility is strong, and it can operate under high organic load conditions. Due to the fact that anaerobic hydrolysis acidification reactors and drip bed reactors require almost no oxygen supply, they significantly save energy consumption and operating costs.

3. Stable operation

Due to the strong adaptability of anaerobic hydrolysis bacteria, the stability of system operation is better than conventional treatment processes, and it is also easy to recover from shock loads. The operation and management are convenient, and the scope of application is wide.

★ Scope of application of food wastewater recycling system

1. Food factory, beverage factory, beer factory

2. Agricultural and sideline product processing enterprises
