Abstract of EP0362435 A method to determine performance of a treating agent (CA) added to a system body of liquid to enhance performance of the liquid body is determined by employing an inert fluorescent tracer (T) in a known T:CA dosage proportion, prepared on the basis of a concentration of CA (e.g. ppm) proposed for optimum performance in the liquid body.

The method comprises the steps of adding a known amount of a polyelectrolyte treating agent to water being treated in a water treatment process. Then, a fluorescent material having the opposite electrical charge as the polyelectrolyte is added to the water treatment process in a concentration of from 0.001 to 750,000 parts per million based on
The liquid can be sampled or continuously monitored at any point of addition, from within the system or its discharge. By comparing fluorescent emission of the system liquid with a standard solution containing a known concentration of chemical treatment +tracer, the concentration of the chemical treatment within the liquid system is determined.

For nutritive polypeptide samples without enzyme, gelation is induced by subjecting the sample to the following thermal treatment process: temperature increased at constant rate of 2 min- 1 from 40 to 90 掳C, kept at 90 掳C for 30 min, cooled at 1 min- 1 from 90 to 30 掳C, and kept at 30 掳C for 1 5 min.
US3964294A - Technique and system for coding
Microencapsulated spheroids containing a coded, volatile electron absorbing substance are dispersed into a material to be regulated such as crude oil in a tanker. Samples of the material such as an oil spill are collected and the source of the material is determined by electron capture gas chromatographic detection of the electron absorbing substance.

- How a wastewater treatment plant can improve water quality in Iran?
- public awareness and concerns about water issues, and enforcement of environmental legislation in Iran, wastewater treatment plants must enhance the rate of removal of pollutants. Here, it is stated that the percentage of the population covered by wastewater facilities in urban and rural areas should reach 90% and 15%, respectively, by 2040.
- What is the purpose and application of wastewater treatment in Iran?
- The most important purpose and application of wastewater treatment in Iran is the use of effluent for agricultural water supply. Wastewater treatment in Iran consists of two sections: primary treatment and biological treatment.
- Are Iranian industrial wastewater treatment plants the same as developed countries?
- Construction and development of Iranian industrial wastewater treatment plants (WWTPs) are the same as in developed countries. According to the Iranian small industries and industrial parks organization report ( ISIPO 2012 ), the first WWTP with a capacity of 1,700 m 3 /day went into operation at Abbas-abad industrial park in 2005.
- Is there a roadmap for the development of wastewater treatment technology in Iran?
- The present work is a part of the national project of roadmap for the development of wastewater treatment technology in Iran, which has been completed by the authors themselves, and financially supported by Iran’s NWWEC (project code: 37796). Supplementary file 1 contains Table S1.
