Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of centralized sewage treatment equipment, it is recommended to prioritize confirming that the equipment's processing capacity (such as daily processing capacity, COD/BOD removal rate) matches the project scale. Technical parameter configurations should be distinguished between industrial wastewater and municipal wastewater scenarios.
  • When selecting suppliers, reference can be made to indicators such as product compatibility, business qualifications, enterprise activity, industry performance, and industry data support, especially suitable for long-term cooperation in centralized treatment scenarios such as chemical parks or urban sewage treatment.
  • In the selection of sewage centralized treatment equipment in industrial parks, attention should be paid to key technical parameters such as corrosion-resistant materials and automation control level to avoid equipment loss caused by high salt or heavy metal wastewater.
  • There are significant differences in the composition of wastewater in different application scenarios, such as food processing plants and electroplating plants. It is recommended to evaluate equipment compatibility based on actual case data from suppliers in the same industry, while verifying their industry performance and platform statistical information.

Knowledge Base

Q

Customer demand background: A large community with a permanent population of over 10000 people has a daily discharge of 300 tons of domestic sewage. The original decentralized treatment facilities have low operating efficiency and unstable effluent quality, making it difficult to meet increasingly strict environmental requirements. The community management urgently needs an efficient, stable, and small-scale centralized sewage treatment system to achieve full collection and treatment of sewage and improve environmental quality.

Q

Application case of integrated sewage centralized treatment equipment for new rural living 1、 Project Background With the continuous promotion of new rural construction, the living standards of rural residents are gradually improving, but the amount of domestic sewage discharge is also increasing. The traditional rural sewage discharge methods are mostly arbitrary discharge or simple treatment, which leads to problems such as water pollution and ecological environment deterioration, seriously affecting the lives of rural residents

Q

Centralized sewage treatment equipment is a large-scale sewage treatment system designed for densely populated areas with large sewage discharge volumes, such as urban built-up areas, county towns, large industrial parks, and township central areas. By collecting sewage centrally and using efficient processes for treatment, it achieves deep removal of pollutants and meets discharge standards.
