Treatment plan for wastewater containing approximately 10,000 mg/L of xylene
Thread Content
The wastewater from the new project planned to be built contains about 10,000 mg/L of xylene. Does anyone have any experience in dealing with this issue that they could share?
Xylene can be adsorbed and recovered using resin-based methods, reducing its concentration to between 1-10 ppm. We can arrange experiments to observe the results on-site. As the largest producer of specialty resins in China, we hope to be able to assist you
Resin can be used for adsorption to recover xylene, with good results
It can be fed into a oil-water separation unit, where the organic phase, namely xylene, can be recovered, thereby reducing resource waste. Pure physical techniques are used, with no chemicals added.
Can oil and water be separated at 10,000 mg/L as well?
Can thb716 have a design? Our company has also encountered this problem
Our company can provide turnkey projects as well as design services. Our company’s process consists of: 1. Technical consultation for wastewater treatment, 2. Verification of technical solutions, 3. Industrial-scale design, 4. Turnkey projects, 5. After-sales service and technical support. Our company is the largest producer of specialty resins in China – Lanxiao
Special resin adsorption? I would like to ask what the adsorption capacity of the resin is? At a concentration of 10 g/L, what is the processing volume per cycle? Have you considered this?
A concentration of 10,000 ppm can be treated using adsorption resins. One cubic meter of resin can absorb 100 kilograms of material, resulting in a treatment capacity roughly 10 times the volume of the resin used; this meets the requirements of industrial design. Moreover, a relatively simple fixed-bed operation mode can be employed. The boiling point of xylene is not high, around 140 degrees. Once the resin becomes saturated with adsorbed substances, it can be regenerated through steam stripping, allowing it to be reused. The highest concentration of phenol we have worked with was 30,000 ppm in the dye industry, and a continuous ion-exchange system was used for the engineering design. All can meet the owner’s requirements. Resin adsorption for removing benzene-ring compounds is a highly mature technology; it is used in the purification of wastewater containing aromatic inert organic substances as well as in the treatment of acids generated as by-products, such as those from benzene, toluene, chlorobenzene, benzyl chloride, and chloro (bromo)phenols. It is also applied to the treatment of wastewater containing phenols, aromatic alcohols, and aromatic organic acids, such as phenol, p-(o-, m-)cresol, p-(o-)***phenol, p-aminophenol, paracetamol, benzyl alcohol, phenylethanol, chlorobenzoic acid, benzoic acid, salicylic acid, 2,4-D, etc
Sure, we have handled similar cases before.
Our company’s oil-water separation equipment occupies a small space, features automated control, and operates on the principle of wetting and coagulation. It is a purely physical process that does not require the use of any chemicals, nor does it introduce any other pollutants. The water output can have levels below 10 ppm. Xylene can be recovered, thereby enabling resource utilization and cost savings. The operating costs of this equipment are low, and our company is able to provide on-site testing.
