Pollution Prevention Potential at an Aircraft Repair Facility

This paper presents the results of a project that evaluated the potential of brush plating as a substitute process for hard chromium and nickel tank plating to reduce the quantity of waste generated during the repair and overhaul of gas turbine engines. The project was conducted dur ing 1992 by Sc ience App l i ca t ions International Corporation (SAIC) for Tinker AFB a n d t h e U . S . E P A ...

Evaluation of optimal waste management in the plating industry based on the Delphi Method and Fuzzy Analytic Hierarchy Process (Case Study: Paitakht Industrial District of Tehran)

The plating industry is one of the main toxic chemicals consumers, which uses various chemicals, including solvents, acids, bases, cleansers, sophisticated organic ingredients, and metal salts of cadmium, nickel and chromium. Due to the growing production of industrial waste in spite of actions related to these wastes’ management, no comprehensive pattern was introduced at different levels. Thi...

Effects of Pretreatment Prior to Electroless Ni-P Plating on Fatigue Behavior of SAE 1045 Steel

Electroless Ni-P (EN) plating, as an important group of metallic coatings, employed in a wide range of industrial applications. The current work aims to investigate the effects of pretreatment process before EN plating on fatigue behavior of SAE 1045 steel. The specimens of rotating bending fatigue test were prepared from the steel in two series. A group of samples used in as-polished con...

کارآیی حذف کروم، نیکل، روی و کدورت از فاضلاب صنایع آبکاری به روش الکتروکوآگولاسیون

Background and purpose: Heavy metals such as chromium, nickel, and zinc are the most common contaminants found in the plating wastewater that cause environmental pollution due to non-biodegradability. This study investigated the removal of chromium, nickel, zinc and turbidity from wastewater of plating and galvanized industries by electrocoagulation technology. Material and methods: This study...
