Sand wahsing process with flocullant
1. Before using, dissolve the sand washing flocculant in water to make a 0.1 percent -0.2 percent concentration aqueous solution.
2. For dissolution, use water that is free of suspended impurities. It's best to use tap water.
3. Mechanical stirring can be used for dilution and stirring; the number of revolutions per minute is approximately 200; it can be used after stirring for 60 minutes.
The flocculant can be used to treat sewage in the sand washing industry. It is the same as sewage sedimentation when used for sludge sedimentation and dewatering. The dissolving liquid is used at a concentration of 0.1 to 0.2 percent.
After dissolving into a glue-like liquid, it is mixed into the sludge. Sand washing sewage has the following characteristics: khaki, uniform, and viscous, long-term standing without stratification, specific gravity: 11201146; mud content: 32%-79%; pH value: 68%. Experiment with qualitative sewage In a 1L beaker, add 500mL of the construction site's mud water sample, multiple types of flocculants, and the dosage is roughly controlled at the mud separation as the standard.
Examine and contrast the dehydration of the mud water (the mud water separation situation) and the mud settled in the lower layer. The degree of granularity. Then, pour the upper layer of clear water onto the ground, spread the lower layer of mud on the ground, and observe the mud's stackability.
