§ What test work will the laboratory carry out?
§ How critical is water quality to customers?
Product water quality requirements § How many megohms. Centimeters (MΩ · cm) is required for the system product water resistivity (or the derivative relationship between electrical conductivity)?
§ How much Eu / ml is required for the system heat source index?
§ How many cfu / ml is required for the number of water-producing colonies in the system?
§ How many ppb should the total organic pollutants of the TOC produced in the system be less than?
* List the corresponding water quality requirements of pure water and ultra-pure water separately. Choose the appropriate model according to the water production index of the corresponding model
Pure water consumption § What is the total daily water requirement?
§ What is the maximum water consumption per unit of peak time per day?
§ How often do you use water (2 days a week, 1 week per month, daily, ...)?
* You can choose the appropriate model according to the amount
Source water condition Hegong sales engineer will test the TDS value of source water for you for free. If the TDS value is determined:
TDS <200ppm pure water system can use single-stage reverse osmosis system pure water machine and ultra pure water machine
200≤TDS≤500 Consider reducing the frequency of consumable replacement. It is recommended to use a two-stage reverse osmosis system with high-purity water machine and ultra-pure water machine
TDS≥500 can only use two-stage reverse osmosis models or ultrapure water machines (TDS: total dissolved solids, the unit of measurement is mg / L (mg / L or ppm). Total solids. In a physical sense, the more dissolved matter in water, the greater the TDS value of water, the better the conductivity of water, and the greater the conductivity value.)
Purification process of prepared water§ What kind of purified water process does the equipment use and what are the advantages?
§ What are the countermeasures for high-salt and high-hardness conditions? Is secondary reverse osmosis used? Dual-stage reverse osmosis plus ultrafiltration pretreatment is recommended.
Appearance desktop: placed on the laboratory table with a small volume.
Floor-standing machine: suitable for customers with large water consumption, the system is beautiful, and it is more convenient to replace consumables.
Security, control and alarm
§ Whether there is pure water and ultra-pure water low water quality alarm prompt to replace consumables.
§ Have you considered some alarm measures for water leakage, such as the installation of sound and light alarm devices?
§ Is the water circuit isolated?
§ Whether to consider the dual mechanism water mode can avoid the interruption of pure water supply.
cost analysis:
§ How cost-effective is the equipment?
What is the annual operating cost of the system? It is recommended to calculate the annual operating cost.
Practical and convenient equipment use and maintenance Is it convenient to replace consumables?
Is the system cleaning convenient and complete? Is it fully automatic programmable cleaning?
The children's study table and chair set is furniture for children aged 3-18 to learn to write homework. The table has a lot of storage space. The table board is made of solid wood core material. The table board can be adjusted and the table legs can be raised and lowered to meet various requirements. Children of height can do homework and draw pictures; the table can be used from kindergarten to university. Fashionable color schemes make children love to learn more. Because of the large storage space, children can also cultivate good storage ability.
