Working Principle
       When using a circulating water supply system, water quality treatment of the circulating water needs to be considered based on the quality of the water used, and adding water treatment chemicals is one of the important measures for water quality treatment in the circulating water supply system.
       The WA series of dosing equipment produced by our company is specially designed for adding water treatment chemicals with various properties such as water quality stabilizers, coagulants, and disinfectants.

Features
       This equipment features compact structure, easy installation and operation, stable performance, low energy consumption, corrosion resistance, and low noise.

Scope of Application
       1, Dissolution, stirring and dosing of coagulants and disinfectants in water supply projects.
       2, Preparation and dosing of various acid and alkali solutions.
       3, Preparation and dosing of regeneration liquid in softening and desalination treatment.
       4, Preparation and dosing of water quality stabilizer for circulating cooling water.

Operating Instructions
       1, When the dosing equipment must be used continuously, at least two sets of devices are required: one for working and one for preparing the medicinal solution.
       2, When adding chemicals, the circulating cooling water system needs to be cleaned with water or chemicals to activate the metal surfaces of the cooling tower filler and heat exchanger pipes, and then perform pre-filming treatment. The dosage of pre-filming chemicals is 200–300 ppm and the pre-filming time is 24–48 hours.
       3, According to the required concentration of the liquid medicine, the volume of the medicine tank and the purity of the medicine, measure the amount of medicine and water, add the medicine to the medicine tank, and then add the required amount of water.
       4, Start the mixer to completely dissolve the added medicine and stir evenly. Before dosing, open the water inlet valve to fill the solution tank. At the same time, adjust the metering device to the required dosing amount, and then open the angle valve at the bottom of the solution tank to start dosing.
       5, In order to prevent the concentration of circulating cooling water from increasing, pipeline filters and bypass filtering devices need to be installed.
