CN101570388A - Harmless recycling treatment process
A harmless recycling treatment process for urban sludge carries out urban sludge treatment through the prior pulverized coal boiler and coal conveying and tail exhaust treatment systems in a power plant. In the treatment process, flue gas extracted from the front part of an air preheater of a power plant pulverized coal boiler is mixed with flue gas extracted from the back part of a power
Luo et al. (2011) studied effect of trace amounts of polyacrylamide (PAM) on long-term performance of activated sludge by using four lab-scale identical reactors of an internal diameter 10 cm
CN102001804A - Method for degrading polyacrylamide
The invention relates to a method for degrading polyacrylamide in dewatered sludge, which comprises the following steps: preparing mature compost, namely return material, by multiple return compost tests of matured sludge of aerobic compost, wherein the water content of the return material is 40 to 50 percent; mixing the sludge and return material in a certain volume ratio; and under a
Harmless treatment of used foundry sands and dewatered municipal sludge by microwave Article in Metalurgija -Sisak then Zagreb- 54(3):459-461 · July 2015 with 13 Reads How we measure 'reads'
Harmless treatment and resource utilization of stainless
1. Introduction. Stainless steel is a widely used and versatile material, an oxide layer is formed during stainless steel production and processing, and this oxide layer reduces the corrosion resistance of steel (Li et al., 2014).At present, the common treatment for stainless steel strip surfaces is pickling using nitric and hydrofluoric acids to remove the oxide layer (Li et al., 2011).
Tangshan Municipal Harmless Sludge Treatment Project Publish Date：2012-04-20 Tangshan municipal harmless sludge treatment project is invested and constructed by Tangshan Municipal Drainage Ltd., which is located in the old plant of Tangshan City Fengrun Sewage Treatment Plant.
CN105859077A - PAM (polyacrylamide) dewatered sludge
The existing method has the problems of low organic matrix leaching amount, low methane yield, long retention time and the like caused by poor digestive efficiency due to oversize flocs in the PAM (polyacrylamide) dewatered sludge anaerobic digestion process, and also has the possibility that the PAM can be degraded into monomer acrylamide.

- Is aluminum chloride safe and responsible disposal?
- Safe and responsible disposal of aluminum chloride?
- This answer affirms that reacting aluminum with HCl is a (seemingly convenient) way to produce hydrogen for use in other experiments, but the byproduct, AlCl 3, is rather nasty.
- Is there a solid aluminum chloride waste?
- According to the other answer and Karl's comment on it, there is no solid aluminum chloride waste unless you go out of your way to make it, so perhaps my question is now somewhat mismatched with my intent. – R.. GitHub STOP HELPING ICE @R.. Jup. Unless you use dry HCl gas instead of dilute hydrochloric acid. ;-)
- Where does scrap aluminium come from?
- Scrap aluminium comes primarily from either manufacturing scrap or end-of-life aluminium products such as vehicles, building materials, and consumer products. Manufacturing scrap includes shreds, shavings, cuttings, and other leftover aluminium from manufacturing processes.
- What happens if you swallow polyaluminium chloride?
- Polyaluminium Chloride 10 - 18% Solution 11 TOXICOLOGICAL INFORMATION INHALATION Vapours may irritate the respiratory system and cause coughing, asthmatic breathing and breathlessness. INGESTION Swallowing concentrated chemical may cause severe internal injury. Liquid irritates mucous membranes and may cause abdominal pain if swallowed.
