PAM cost accounting method for sewage treatmentIn terms of the use of sewage treatment chemicals, PAM is the best-acting agent. In addition to the treatment effect of sewage, the other side is concerned with the cost of use. We use the coal-washing wastewater as an example to calculate the cost. 2 g of an anionic PAM dry powder was dissolved in 1000 ml of water to prepare a PAM solution having a concentration of 1 Torr. Take 100ml of washing coal wastewater for a small test. After repeated tests, adding 1ml of 1‰ PAM solution to the wastewater treated with 100ml of coal washing wastewater can achieve the desired effect. With such a concentration of coal washing wastewater, 10 tons of PAM dry powder is required for one ton of treatment, and the unit price of anionic PAM is calculated at 10,000 yuan/ton. It takes 0.1 yuan of material cost to treat one ton of coal washing wastewater. The properties of wastewater in different industries are different. When selecting sewage treatment chemicals, it is necessary to do a small test in the laboratory and select the appropriate PAM products to avoid waste. Noel Chemical has a professional operation team, and it is recommended for different customers. PAM products. |
