Design and Filtration of Drainage System in Pharmaceutical Dust-free Workshop
2024.11.12
In the pharmaceutical industry, the construction of dust-free workshops is of crucial importance. As a key link, the design and filtration of the drainage system are directly related to the quality and safety of drug production. Guangzhou Kunling Purification Equipment Co., Ltd. has rich experience in the construction of pharmaceutical dust-free workshops. Today, we will introduce in detail the design and filtration of the drainage system in pharmaceutical dust-free workshops.
I. Importance of Drainage System in Pharmaceutical Dust-free Workshop
Pharmaceutical dust-free workshops have extremely high requirements for the environment. Any tiny pollution may affect the quality and safety of drugs. If the drainage system is not designed reasonably or filtered thoroughly, the following problems may occur:
(A) Microbial contamination
If there is stagnant water or poor water flow in the drainage system, bacteria, fungi and other microorganisms are easy to breed. These microorganisms may spread to the entire workshop along with the drainage system, causing serious pollution to drug production.
(B) Cross-contamination
Different drug production processes may generate different wastewaters. If the drainage system does not have effective isolation and classification, cross-contamination may occur between different wastewaters, affecting the quality of drugs.
(C) Affecting air quality
The peculiar smell and harmful gases in the drainage system may spread to the workshop through the pipeline, affecting the air quality and then affecting the drug production and the health of operators.
II. Design Principles of Drainage System in Pharmaceutical Dust-free Workshop
To avoid the occurrence of the above problems, the design of the drainage system in pharmaceutical dust-free workshops should follow the following principles:
(A) Diversion design
According to different wastewater sources and properties, diversion design is carried out. For example, wastewater containing high-concentration organic matter is discharged separately from ordinary wastewater, and wastewater containing harmful substances is treated separately. In this way, cross-contamination between different wastewaters can be avoided and the efficiency of wastewater treatment can be improved.
(B) Slope design
The drainage pipeline should have a certain slope to ensure that the wastewater can flow smoothly and avoid stagnant water. Generally speaking, the slope of the drainage pipeline should not be less than three thousandths. At the same time, a drain outlet should be set at the low point of the pipeline to drain the stagnant water in time.
(C) Sealing design
The pipelines and connections of the drainage system should have good sealing performance to prevent wastewater leakage and odor diffusion. Materials such as sealant and rubber gasket can be used for sealing to ensure the sealing performance of the drainage system.
(D) Easy to clean and maintain
The drainage system should be designed to be easy to clean and maintain. For example, at the bends and connections of the pipeline, a structure that is easy to disassemble should be adopted to facilitate regular cleaning and inspection. At the same time, inspection ports and drain valves should be set to facilitate the maintenance and repair of the drainage system.
III. Filtration Measures of Drainage System in Pharmaceutical Dust-free Workshop
To further ensure the cleanliness and safety of the drainage system, effective filtration measures need to be taken. The following are some common filtration measures:
(A) Grille filtration
Set up a grille at the drain outlet to intercept larger solid particles such as paper and plastic. The pore size of the grille should be selected according to the nature and flow rate of the wastewater, generally 5 - 10mm.
(B) Sedimentation tank filtration
Set up a sedimentation tank in the drainage system to precipitate heavier particulate matter such as sand and silt in the wastewater. The design of the sedimentation tank should consider the flow rate and flow velocity of the wastewater to ensure that the sand and silt can be effectively precipitated.
(C) Oil-water separation
For wastewater containing grease, an oil-water separator should be set up to separate the grease from the wastewater. The oil-water separator can use physical separation or chemical separation methods to separate the grease from the wastewater to avoid clogging and pollution of the drainage system and wastewater treatment equipment by grease.
(D) Biological filtration
For wastewater containing organic matter, biological filtration can be used for treatment. Biological filtration uses the metabolic action of microorganisms to decompose organic matter in wastewater into harmless substances. Biological filters can use different processes such as biofilm method and activated sludge method, and be selected according to the nature and treatment requirements of wastewater.
