Purchasing Guide

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

  • In the actual procurement process of water separators, it is recommended to prioritize confirming key technical parameters such as processing flow rate and separation accuracy to ensure compatibility with production lines. For example, in the chemical industry, high viscosity liquids are often processed and corresponding specifications and models need to be selected.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. Such suppliers have richer application cases of water separators in different fields such as petroleum and food processing.
  • For scenarios such as ship ballast water treatment or industrial wastewater reuse, it is necessary to consider the corrosion resistance and pollution resistance design of water injection separators. The applicability of different materials (such as stainless steel or polypropylene) varies greatly.
  • When purchasing water separators, it is usually necessary to focus on the industry performance of the supplier, such as whether there is a stable supply record in the power or pharmaceutical fields. Such data can be used to assist in judgment through industry platform statistical information.

Knowledge Base

Q

This article analyzes the key points for selecting oil-water separators for excavators, including working principles, common types, and applicable scenarios, to help users choose suitable products based on actual needs and ensure efficient operation of the equipment.

Q

The catering oil-water separator is a specialized equipment used in the kitchen of restaurants in the catering industry to separate oil and water, commonly known as an oil separation tank. Dishwashing water and pot washing water in the catering industry always produce some oily wastewater. If these oily wastewater are directly discharged into the sewer, it will not only easily cause sewer blockage, but also damage the environment. This is not allowed by the Environmental Protection Bureau, so it is necessary to install oil filters
