Purchasing Guide

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

  • For procurement requirements that require the use of external inlet microfiltration machines, it is recommended to prioritize confirming whether key technical parameters such as filtration accuracy and treatment flow rate match the on-site water quality treatment requirements, in order to avoid affecting the sewage treatment effect due to non-compliance with specifications.
  • External inlet microfiltration machines are widely used in industrial wastewater pretreatment or aquaculture circulating water systems. When purchasing, the filter material (such as stainless steel or nylon) and the model with suitable corrosion resistance can be selected based on specific scenario requirements.
  • When selecting suppliers, priority should be given to product matching, business qualifications, enterprise activity, industry performance, and enterprises with industry data support or platform statistical information to ensure equipment supply stability.
  • In the actual procurement process, attention should be paid to actual factors such as equipment operation energy consumption and footprint. Some high flow models may require supporting pump station upgrades, and it is recommended to evaluate installation conditions in advance.

Knowledge Base

Q

The core selection of the two lies in the quality of the incoming water, filtration requirements, and operating costs. The key differences are as follows: firstly, the filtration direction, where the incoming water enters from the inside and exits from the outside, and impurities are intercepted on the inner wall of the filter cartridge for thorough flushing; External inflow "external inflow and internal outflow", impurities adhere to the outer wall of the filter cartridge, and are easily affected by the impact of water flow on the filtration effect. Secondly, it is suitable for water quality, with low concentration suspension (SS ≤ 50m) suitable for the inflow water

Q

It is mainly suitable for occasions that require fine filtration treatment, and can efficiently remove small particles in water to ensure that the water quality meets specific standard requirements. This device plays an important role in industrial and urban wastewater treatment, circulating water system purification, agricultural irrigation water pretreatment, and other fields due to its easy operation, low maintenance cost, and efficient filtration performance.

Q

External inlet microfiltration machine is mainly used to remove suspended solids, particulate matter and other impurities in water. It achieves purification treatment of sewage through filtering media, and has the characteristics of high automation, low operating costs, and easy maintenance. This device is suitable for multiple scenarios such as industrial wastewater treatment, urban sewage treatment, and reclaimed water reuse, providing effective technical support for environmental protection and resource conservation.
