This paper discusses the potential for algal biofuel production under resource-limited conditions in Texas. Algal biomass and lipid production quantities are estimated using a fully integrated biological and engineering model that incorporates primary resources required for growth, such as carbon dioxide, sunlight and water. The biomass and lipid production are estimated at the county resolution in Texas, which accounts for geographic variation in primary resources from the Eastern half of the state, which has moderate solar resources and abundant water resources, to the Western half of the state, which has abundant solar resources and moderate water resources. Two resource-limited scenarios are analyzed in this paper: the variation in algal biomass production as a function of carbon dioxide concentration and as a function of water availability. The initial carbon dioxide concentration, ranging from low concentrations in ambient air to higher concentrations found in power plant flue gas streams, affects the growth rate and production of algal biomass. The model compares biomass production using carbon dioxide available from flue gas or refinery activities, which are present only in a limited number of counties, with ambient concentrations found in the atmosphere. Biomass production is also estimated first for counties containing terrestrial sources of water such as wastewater and/or saline aquifers, and compared with those with additional water available from the Gulf of Mexico. The results of these analyses are presented on a series of maps depicting algal biomass and lipid production in gallons per year under each of the resource-limited scenarios. Based on the analysis, between 13.9 and 154.1 thousand tons of algal biomass and 1.0 and 11.1 million gallons of lipids can be produced annually.

Electrocoagulation Process

Waste water treatment by industry usually uses chemicals that may lead to additional environmental pollution load. On the other hand, water demand increases and environmental regulations regarding waste water disposal requirements that apply more stringent. It is necessary for waste treatment technique that accommodate this requirement. Electrocoagulation process is a technique of wastewater treatment that has been chosen because the technique is environmentally friendly. This paper will review some of the research or application electrocoagulation process which is conducted on industrial waste water. Types of industrial waste water that is to be reviewed include: industries batik, sarongs, textiles, palm oil, slaughterhouses, food, leather tanning, laundry, pulp and paper. Overview reviewed in this research include the waste water treatment process in several processing variations such as: change in time, electricity and kind of electrodes. The results of the research with electrocoagulation process in the industry are the removal efficiency of TSS, COD, BOD5, Chrome, phosphate, surfactants, color turbidity influenced by several factors including time, strong current, voltage, distance and type of electrode and pH. The results of the study with electrocoagulation process in the industry is the removal efficiency of TSS, COD, BOD5, chromium, phosphate, surfactant, turbidity color that are influenced by several factors including time, strong current, voltage, distance and type of electrode and pH. It is hoped the information presented in this article can be a reference for similar research for the improvement of research on the process ektrokoagulasi.Key words: elektrocoagulation, removal eficiency, environmental friendly

: Manuscript discussed about the role of polysaccharides and their derivatives in the removal of metal ions from industrial waste water. Quick modernization and industrialization increases the amount of various heavy metal ions in the environment. They can possess various disease in humans and also causes drastic environmental hazards. In this review the recent advancement for the adsorption of heavy metal ions from waste water by using different methods has been studied. Various natural polymers and their derivatives are act as effective adsorbents for the removal of heavy metal ions from the waste water released from the industries and the treated water released into the environment can decreases the chances of diseases in humans and environmental hazards. From the literature surveys it was concluded that the removal of heavy metal ions from the industrial waste water was important to decrease the environmental pollution and also diseases caused by the heavy metal ions. Graft copolymers were acts as most efficient adsorbent for the removal of heavy metal ions and most of these followed the pseudo first order and pseudo second order model of kinetics.
