Performance Evaluation of Water Treatment Agents

The performance evaluation of water treatment agent includes the evaluation of the role played by its components, which can be used for screening and formulation design of water treatment agent, to help enterprises better sample dosage control and parameter monitoring, so as to obtain more safe and environmentally friendly water quality, and maintain the durability of the whole water treatment equipment.

Evaluation of scale inhibition performance of water treatment agent

The test solution was prepared by adding some litres of water, calcium chloride and sodium bicarbonate, and then water treatment agent. The pH value and ion concentration are increased by evaporation and concentration under constant temperature, so as to meet the requirements of simulated water environment. Evaluation and screening of scale inhibitors are carried out. After calcium bicarbonate was decomposed into calcium carbonate at an accelerated rate and reached equilibrium, the calcium ion concentration in the clarifying liquid was analyzed and determined. The larger the mass concentration of calcium ions, the better the scale inhibition performance of the water treatment agent, the higher the scale inhibition rate, in order to evaluate the scale inhibition performance of the agent.

Evaluation of corrosion inhibition properties of water treatment agents

Add the water treatment agent to the treatment water, and put the experimental hanging piece, and then the test hanging piece after the test is treated and weighed, calculate the corrosion rate of the test hanging piece and the corrosion inhibition rate of the agent.

Evaluation of bactericidal properties of fungicides

Oxidizing fungicides and non-oxidizing fungicides were added into the experimental water to screen the fungicides suitable for sterilization process and select the optimal concentration.

Evaluation of coagulation performance

Take the water to be treated, add water treatment coagulant, mix, flocculate and precipitate under certain hydraulic conditions, and evaluate the coagulability of water treatment agent according to the water quality parameters determined after the test.

Performance evaluation of dispersed iron oxide

The precipitation of iron oxide on the material surface of the system is easy to cause a large number of iron bacteria, and will also reduce the heat transfer efficiency, thus leading to corrosion under scale. The test proves that the water treatment agent can help actively disperse iron oxide, then its performance evaluation is good.

Biodegradation performance evaluation

At present, the method used to test the biodegradation performance is the shaking bed test. The basic principle is: there are a certain type and number of microorganisms in the biodegradable aqueous solution, the microorganisms have decomposition and transformation effect on it, and the potassium permanganate index of the solution will gradually decrease with the passage of time. The rate and degree of reduction were used to reflect the biodegradability of the substance.
