Pharmaceutical industry represents a range of industries with operation and processes as diverse as its product. Hence effluents coming from pharma industries vary from industry to industry. Thus it is almost impossible to describe a typical pharmaceutical effluent because of such diversity. Waste water is generally evaluated in terms of temp, pH, Total suspended solid (TSS), BOD, COD, Oil & gr...

Terpenoids are the largest and most structurally diverse family of natural products found in nature, yet their presence in bacteria is underappreciated. The carbon skeletons of terpenoids are generated through carbocation-dependent cyclization cascades catalyzed by terpene synthases (TSs). Type I and type II TSs initiate cyclization via diphosphate ionization and protonation, respectively, and ...

A typical real-time system, the Telephone Switching System (TSS), is a highly complicated system in design and implementation. This paper presents the formal design, specification, and modeling of the TSS system using a denotational mathematics known as Real-Time Process Algebra (RTPA). The conceptual model of the TSS system is introduced as the initial requirements for the system. Then, the ar...

The influence of some effective parameters on the removal efficiency of a 500 liters UASB reactor was investigated. The best conditions to removal the pollution loading is pH=7 and temperature range of 35 to 38°C. The optimal of hydraulic retention time in medium COD amounts (800-1800 mg), is 5 h and in the high COD load (1800-2600 mg) is 6 h. Furthermore, the hydraulic rate is between 0.67-0.8...

the efficiency of existing municipal wastewater treatment plants has been affected by the increase of incoming organic load caused by the expansions in developing countries. in the present investigation, the effect of chemically enhanced primary treatment (cept) process was studied on the enhancement efficiency of a municipal wastewater treatment plant in tehran, iran. jar test results showed a...

The present study aimed to evaluate the effect of dipping time and temperature of hot water and type of packaging on qualitative traits of Orlando tangelo variety of tangerine. This study was conducted as a factorial experiment in a completely randomized design with three repeats. The treatments consisted of dipping in hot water at seven water levels at 53°C and 58°C each for 1, 2 and 4 minutes...

Treatment of liquid waste using iron coagulant produces a by-product in the form sludge which requires large handling costs. To reduce environmental pollution and treatment costs, will be used as raw material for manufacture coagulant. This study aims to determine whether from textile WWTP can effectiveness coagulants made sludge, this compare results coagulation-flocculation process commercial...

Persimmon is a climacteric fruit and very perishable. Changes in several physiological attributes greatly affect its quality market value. The current study was designed to assess the effect of chitosan solution (an edible coating material that can improve postharvest performance) on physico-chemical persimmon during storage. fruits were harvested, cleaned then dipped various concentrations (1%...

In this study, landfill leachate treatment by coagulation and optimization of process parameters were aimed. Alum (Al2(SO4)3) Poly Aluminum Chloride (PACl) used as coagulants to remove total suspended solids (TSS) from leachate, coagulant dose, reaction time, pH optimized variables. The Box-Behnken, one the response surface methodology designs, was in modeling process. R2 values very high (&amp...
