HTL Blackwater Water Treatment

High suspended solids: Adjust the flocculant by changing its ionic strength or the dosage used. High total hardness and total alkalinity: Increase the amount of wastewater discharged； Dispersants with better addition effects ； Add a softener to reduce the hardness and alkalinity of the graywater.

Let the pharmaceutical manufacturers take a look and see if there are any good solutions. In fact, the best solution is to use good water to replace the poor-quality water

If the hardness increases while the type of coal remains unchanged, it indicates that the amount of wastewater discharged is low; the calcium and magnesium ions in the water system have not been kept at a balanced concentration, so the amount of wastewater discharged needs to be adjusted； The alkalinity in the water vaporization system is related to the ammonia nitrogen content in the water; in other words, the flashing system is not functioning properly and deviates from its operating parameters, failing to achieve the desired flashing effect. It is also necessary to check the amount and method of addition of the dispersant, as this substance plays a role in controlling alkalinity. The suspended solids level is high; it may be due to poor sedimentation in the clarification tank, so the amount of flocculant used should be adjusted accordingly ； It would be best to check the sediment buildup at the bottom of the sedimentation tank; too much sediment there can also lead to high levels of suspended solids ； When these three indicators are high, it is possible to improve water quality in the system by increasing the amount of wastewater discharged. However, this only provides a temporary solution; the real cause must be identified in order to address it properly. If the cause is not found, increasing the amount of wastewater discharged may temporarily improve water quality, but it will rise again after some time ；

Adjust the flocculant and increase the wastewater discharge volume

The main function of dispersants is to prevent scale particles and suspended solids from aggregating and depositing. Additionally, they increase the solubility product of scaling substances such as calcium carbonate and magnesium silicate, thereby raising their solubility and ensuring that high levels of alkalinity and hardness do not lead to scaling. The addition concentration of the dispersant is generally only in the range of several dozen PPM, and the dispersant itself has a moderately low acidity; therefore, it has little impact on the alkalinity of graywater and essentially no controlling effect.

Let’s learn a thing or two – our graywater control isn’t that good either
