DE Fluoridation of Domestic Waste Water by using Activated Diatomaceous Earth in fixed Mattress Column Adsorption System

Study aims to eliminate fluoride from treated waste water or ground water through adsorption technique by using Activated Diatomaceous Earth as a sorbent. Study found that there is no change in pH and TDS, but the concentration of Fluoride ions reduced. The most elimination potential of 71.97 mg/kg turned into achieved for activated diatomaceous earth with particle sizes of 0.075-0.425 mm. The absorbance capability of diatomaceous earth (DE) is 20.73% when used as a filtration media. In this analysis, activated diatomaceous earth was used as an adsorbent in a fixed-mattress column adsorption system for DE fluoridation of water. The XRD, BET surface area, FTIR, XRF, Scanning Electron Microscopy (SEM), and pH Point of Zero Charges (pHPZC) evaluation had been executed for adsorbent to explain the mechanisms of absorption and fluoride elimination. The Bradley equation was used to calculate the isothermal data and adsorbent dose. The statistical analyses were performed using Langmuir and Freundlich equations.

Microbiological Aspects

This paper firstly reviews the microbiological aspects of the accumulation of xenobiotic and non-xenobiotic substances from industrial and domestic waste water treatments, with particular reference to hydrocarbons, pesticides and inorganic plant nutrients. The paper goes on to argue that if water bodies are to be used to establish recreational fisheries as well as for water supply and effluent disposal, then the management aim may need to be one of controlled eutrophy. Ramifications of this proposal are considered. The biological aspects of the impact of other recreational and amenity uses of water bodies on water and environmental quality is briefly described. The paper concludes by discussing the training required by potential water managers.

Soil Layering

Multi-Soil-Layering (MSL) method was applied to make appropriate, but high performance and N & P-removable, on-site domestic waste water treatment system. The MSL soil unit is composed from soil layer mixed with 10∼25% of metal iron and pelletized jute. The MSL units were piled in a brick pattern at 5cm vertical and 10cm horizontal distance, which were surrounded by layers of Zeolite. Air can be supplied through porous pipes installed at adequate depths of the MSL system. The systems were tested using model houses. The waste waters, which were pretreated by septic tank to the level of SS 29-75, BOD 42-116, COD 32-56, T-N 29-86, and T-P 6-11 mg−l−1 respectively, could be treated at the rate of 100-850 1·m−2·d−1 without significant clogging. The mean concentrations of treated waters were SS 15, BOD 8.7, COD 11, T-N 6.8, and T-P 0.86 mg·1−1 respectively. Zeolite layers and brick pattern prevent clogging. Metal iron and jute pellets were effective to remove Phosphate and Nitrate. Intensive aeration assists decomposition of BOD, COD, and SS as well as nitrification, but decreases denitrif ication and phosphate fixation. The degree of purification could be controlled by setting adequate aeration.
