Yang* and Kai-Lun Kao Institute of Environmental Engineering, National Sun Yat-S,en University, Kaohsiung, (Taiwan, R.O.C.) (Received May 7, Cited by: 8. Treatment sludges contain high levels of metals and these should normally be managed as hazardous waste or sent for metals recovery. Electrolytical methods may be used to recover metals. Sludges are usually thickened, dewatered, and stabilized using chemical agents (such as lime) before disposal which must be in an approved and controlled Size: KB. Processing of hazardous waste that contains precious metals is a challenge and responsibility that many electroplating companies face. Cyanide- and acid-based solutions, and materials such as plating bath filters and resins, all have the potential to cause injury and harm to our environment if not disposed of properly. (Ultraviolet) radiation, temperature, temperature gradient, chemical agent, and stress (particularly fatigue). Stress Cracking leads to small cracks and even holes in the geomembrane, that allow leakage through the membrane. This can be prevented by using a UV and chemical resistant resin and by limiting high stress in the liner.
The application of synthetic liner in a landfill system can be affected by certain factors such as installation damage, bad design and/or choice of materials, aging, pipes penetrating the liner. The recommended monitoring system involves the use of a double composite liner with a leak detection system between the two liners where the lower composite liner functions as a pan lysimeter for the upper composite liner.

Electroplating involves using electric current to coat an electrode in dissolved metal cations. In metallurgy, it is one of the highest-quality procedures for achieving durable, even coats on metal substrates. However, electroplating requires a high level of .
