Purchasing Guide

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

  • For procurement requirements that require the use of sewage treatment systems, it is recommended to match the actual requirements of industrial or municipal scenarios based on key technical parameters such as daily treatment capacity and COD removal rate. The chemical industry needs to pay extra attention to corrosion-resistant design.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. For example, suppliers with long-term service in the electroplating or pharmaceutical fields usually have more stable technical solutions.
  • When applying sewage treatment systems in the field of food processing, it is important to focus on the efficiency of suspended solids treatment and energy consumption indicators to avoid excessive operating costs in the future.
  • For the decentralized sewage treatment scenario in rural areas, it is recommended to choose a modular design sewage treatment system and verify the supplier's actual operating data and industry performance in similar projects.

Knowledge Base

Q

The selection of an intelligent integrated sewage treatment system is a key issue, as it directly affects the quality of sewage treatment and the stability of equipment operation. Before choosing an intelligent integrated sewage treatment system, we need to consider the following factors. Firstly, we need to understand the amount and quality of wastewater that needs to be treated. The demand for sewage treatment in different scenarios may vary

Q

Integrated sewage treatment equipment - evaluation criteria for the effectiveness of aeration systems and comparison of aeration systems The aeration system in the activated sludge reaction tank of the integrated sewage treatment equipment has the following two functions: ① providing oxygen for aerobic microorganisms, usually air as the gas source; ② ensuring sufficient contact between microorganisms, pollutants, and oxygenated water through thorough mixing and complete homogenization.
