Standard configuration for building water quality testing laboratory

- Aug 20, 2020-

The main functions and functions of the water quality testing laboratory:

1) The nature of the test item itself must be tested on-site, such as disinfectant indicators (residual chlorine, chlorine dioxide, ozone);

do meter

2) According to the requirements of water sample collection and storage methods when collecting samples, water temperature, turbidity, chroma, pH, conductivity, dissolved oxygen and other items should be measured on-site when collecting water samples when going out;

3) Team inspection of water supply companies: The water production staff on duty monitors the turbidity of raw water, sedimentation water, filtered water and factory water, free residual chlorine and chlorine addition in factory water, and monitors the turbidity of the outlet water of the sedimentation tank and the filtered water. Control the turbidity of the factory water;

Configure the device:

Portable residual chlorine, chlorine dioxide rapid tester, portable turbidity meter, portable colorimeter, pH meter, conductivity meter, etc.

Configuration function and role of physical and chemical laboratory testing room:

Physics and chemistry are mainly for routine photometric project determination, volumetric analysis, reagent preparation, etc.; among routine analysis projects, photometric analysis projects have the largest proportion and require high operator skills, so the configuration is selected to combine automated ultraviolet-visible spectrophotometry It can effectively improve work efficiency and improve water quality risk management capabilities during the concentration period of detection tasks. The titration method (namely volumetric method) is time-consuming and requires high operator skills, and chloride, oxygen consumption, and total hardness are routinely required items. Therefore, a titration analyzer can be configured to reduce errors caused by human factors. , And improve work efficiency.

SICOLAB equipment configuration:

UV-Vis spectrophotometer, titration equipment, laboratory benches and washing benches; fume hoods; laboratory benches with reagent racks and auxiliary work benches, medicine cabinets, glassware, utensil cabinets, floor-mounted instruments and equipment, refrigerators, first aid equipment, etc. .

Function and role of large instrument room:

Accurate quantitative detection of heavy metals in water quality and items that require high-precision quantification;

SICOLAB equipment configuration:

Mainly set up a variety of large-scale precision analysis instruments, including atomic absorption, atomic fluorescence, ion chromatography, gas chromatography, etc. The general design equipment includes: instrument table, laboratory table, fume hood, sky platform, computer table, gas cylinder cabinet, washing table , Utensil cabinet, medicine cabinet, first aid equipment, universal exhaust hood, etc.

Function and role of microbiology laboratory:

Detect and cultivate the total number of colonies, total coliforms, heat-resistant coliforms, and Escherichia coli in factory water or raw water in a sterile environment

SICOLAB equipment configuration:

Microbiology laboratories are generally divided into locker rooms, buffer rooms, and clean areas. The buffer rooms are generally used to prepare experimental supplies or place incubators. The clean area requires an operating table and needs to install ultraviolet germicidal lamps according to the area.

Microbiology laboratory test bench surface requirements: waterproof, strong anti-bacteria density; surface material is stainless steel plate.

Balance room

Analytical balances are commonly used instruments in chemical laboratories. High-precision balances have certain requirements on the environment, mainly due to the influence of airflow and wind speed, and the use of fixed tables to avoid vibration. The balance room should be close to the chemical laboratory for easy use, but not suitable Adjacent to high-temperature greenhouses and rooms with strong electromagnetic interference.

Pure water room

Mainly designed experimental equipment: side table and washing table. Most laboratories use ultrapure water machines, which require a large amount of water and can ensure water quality.
