CONTROL OF DISINFECTANTS.

Chlorine Disinfectants and Orp Control

INTRODUCTION The science of water disinfection is still a relatively new field for the tree fruit industry, as the widespread use of water disinfectants in this marketplace has only been occurring over the past couple of decades. In comparison, industrial water systems such as open recirculating cooling systems and evaporative condensers have been receiving chemical treatment for over five deca...

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...

Comparison of disinfectants for biofilm, protozoa and Legionella control.

The aim of this study was to compare the efficiency of different disinfectants applicable to Legionella control in domestic water systems. A domestic water supply simulation unit that allowed simulation of real-world conditions was developed for this purpose. The system, consisting of seven identical rigs, was used to compare treatment efficiency under equivalent conditions of system design, ma...
