Allow emissions.

    Design Principles

According to the production characteristics of the enterprise and the characteristics of the discharged wastewater, according to the principle of “cleaning and diversion” and “classification collection and quality treatment”, according to the research results and engineering practice of chemical wastewater treatment, the project and future wastewater treatment design points are specially For the following three categories:

(1) The first type of wastewater: high-concentration organic matter, high-salt wastewater (production wastewater containing high salinity, high ammonia nitrogen and high concentration of organic matter); such wastewater needs to be concentrated and crystallized to remove salt, and then demineralized. The water quality enters the follow-up process.

(2) The second type of wastewater: medium concentration organic matter concentration, medium and low salt content (low salt process wastewater, process washing water, workshop washing equipment and ground wastewater, tail gas absorption sewage, laboratory drainage, etc.); After biochemistry, it will reach the standard discharge.

(3) The third type of wastewater: low-concentration wastewater (circulating cooling water, domestic sewage, initial rainwater, etc.); such wastewater can be directly biochemical.

Selection of Fine bubble diffuser for in Fine chemical wastewater treatment

Fine Bubble Disc Diffuser Introduction

1.The Fine Bubble Disc Diffuser consists of a rubber diaphragm, several air flow guiding grooves, a chassis support and a spiral gland.

2.The diaphragm is made of high quality rubber raw material and installed on the chassis bracket.

Technical parameters

Working principle of Fine Bubble Diffuser

The chassis support is the support of the diaphragm, which is arched. The upper part of the chassis support is provided with eight air diversion grooves which are distributed around the center to ensure that the air is evenly distributed. The spiral cap joins the lower part of the chassis support to the chassis support. The diaphragm is fixed on the chassis support. The chassis support and the spiral cap are molded by quality ABS engineering plastics.
