PECR-V1 advanced wastewater treatment reactor
PECR-V1 advanced wastewater treatment reactor
The introduced systems of industrial wastewater treatment and sanitary wastewater treatment in the world have used many methods for wastewater treatment so far. In general, the steps of wastewater treatment are divided into three parts: physical, chemical and biological treatment. Each of the above methods has advantages and disadvantages, and using them to achieve results and treat wastewater to recover water and preserve the environment creates many challenges.
Considering this issue, the advanced treatment method of industrial wastewater, sanitary wastewater and domestic wastewater PECR is the use of electrochemical knowledge in solving the problems and complications of using the above mentioned wastewater treatment methods. So that by using these reactors, in addition to reducing operational and operating costs by more than 50%, it will make it possible to achieve the result of water recycling from sanitary and industrial wastewater.
In the PECR-V1 advanced treatment method, the use of electrochemical treatment in the coagulation and electric flotation of polluting substances, as a significant innovation in the water and wastewater treatment industry, a suitable and low-cost alternative compared to the chemical treatment method and in some cases such as biological, which has limitations in high implementation and exploitation costs as well as adverse environmental consequences.
Definition of PECR wastewater treatment process:
The PECR-V1 wastewater treatment method consists of the production of coagulant materials on site using the electrical decomposition of electrodes, and the production of metal ions in the anode and hydrogen gas in the cathode. This action will cause coagulation and separation of pollutants from the wastewater.
Uses of this method in industrial and sanitary wastewater treatment:
This method is very suitable for the treatment of industrial wastewater, treatment of electroplating wastewater and treatment of sanitary wastewater such as gray water and black water. Among the industries in which this method can be used are:
- Slaughterhouse wastewater treatment
- Dairy wastewater treatment
- Purification of leather factory wastewater
- Wastewater treatment of sugar and sugar industries
- Wastewater treatment of paste, canning and fruit juice
- Wastewater treatment of textile industries, dyeing and printing on fabric
- Papermaking wastewater treatment
The amount of removal of pollutants in wastewater using the PECR method:
This method is used for the treatment of human and mineral sanitary wastewater to separate fat, organic load and final clarification, and in industrial wastewater treatment to remove oil and grease, settleable or colloidal suspended solids, heavy metals, organic substances, minerals, turbidity. And…. The following table shows the percentage of pollutant removal in some different wastewaters after treatment by PECR method:
The percentage of removal of heavy metals after treatment | Fat and oil removal percentage | Turbidity removal percentage | COD removal percentage | type of wastewater |
– | 95% | 95% | 80% | Sanitary Wastewater |
– | 95% | 70% | 65% | Fat of food production and cooking units |
– | 98% | 95% | 75% | Dairy |
– | 90% | 85% | 65% | Livestock and poultry slaughterhouse |
95% | 80% | 70% | 55% | Leather production industries |
– | 95% | 95% | 90% | Pistachio washing and sorting factories |
95% | – | 90% | 65% | Textile and dyeing |
– | 98% | 98% | 70% | carwash |
– | – | 85% | 70% | Sugar industry |
– | – | 85% | 80% | Paper and cardboard industries |
– | – | 60% | 55% | Alcohol and liquid paste |
Advantages of PECR-V1 advanced wastewater treatment system:
