Is it a measurement result or a process indicator? Generally, the process indicators do not need to be changed, as long as they are controlled within the range. ； If the measurement results are like this, then the coal type must be considered (can it be changed? ), water quality (sewage discharge volume, wastewater circulation volume), etc., mainly through increasing water replenishment and improving drainage, gradually reducing the hardness of system water.
The hardness index of gray water is 1049, isn’t it just right? Why adjust?
There are dispersant pumps and flocculant pumps in the Texaco process. The operation of these two pumps is related to the water quality of the entire system, and these two pumps are one of the inspection items. You can also slowly change the water quality by increasing the amount of raw water, but it will take a long time.
The best way is to increase the external drainage volume and add fresh water, which can reduce the hardness of gray water! 1409Can this water still be used? For us, over 400 feels quite high. Another option is to increase the dosage of dispersant and flocculant. Reduce solid matter in water!
More than 1,000 is a bit too high. The person above is right. Generally, it is okay between 400 and 600. If it is higher, it will definitely affect the operation cycle of the entire system and increase the number of furnace preparations. In the current situation, the best way is to increase the water circulation volume, increase the external drainage volume, add fresh water, and add anti-scaling agents to reduce system scaling.

Is the amount of replacement water too small? ； Is the ash content of coal too high? Once the cause is found, all you need to do is treat it symptomatically. The first priority is to convert the water quality first to minimize the impact on equipment and pipelines.
Is there any relationship between total hardness and flocculant addition amount?
Personally I don't think it has much to do with it, please ask relevant experts to analyze it.~
