Abstract

Defluoridation by adsorption process is well known technique. Though several established techniques are available, they are found to be expensive and labour intensive. Keeping this in view, a study is being done to remove excess fluoride in drinking water based on the concept of adsorption using locally available materials like laterite, sand and gravel. The studies were being conducted in a column with varying depths of laterite by keeping constant gravel depth. The flow is varied for all the depths and the results obtained were fo ....etc

Abstract

Now-a-days Plastic is everywhere in today s lifestyle. The disposal of plastic wastes is a great problem. These are non-biodegradable product due to which these materials pose environmental pollution and problems like breast cancer, reproductive problems in humans and animals, genital abnormalities and even a decline in human sperm count and quality. In recent years, applications of plastic wastes have been considered in road construction with great interest in many developing countries. The use of these materials in road making is b ....etc

The article presents the reports the performance of municipal waste-water treatment plant using laterite soil-based constructed soil filter (CSF) system. The plant was monitored over a period of 17 months and the result is presented. The dissolved oxygen levels were increased along with the chemical oxygen demand (COD). The bio-chemical oxygen demand (BOD) reduced was significantly reduced. The features of the system are:
lowHRT, high,hydraulic loading, no chemicals, pretreatment and mechanical aeration, odor free, lowenergy requirement.
