Radiation Technology for Sewage Sludge Hygienisation
نویسنده
چکیده
Large amount of sewage sludge is produced in India every day. The sludge is infectious and can spread diseases. It also has essential micro and macro nutrients, especially carbon, useful for soil and crop production. Radiation Technology can be used to hygienise the sludge reliably and affordably and protect health and environment. Addition of useful microorganisms to the hygienised sludge can convert it to a value added manure. Ahmedabad Municipal Corporation (AMC) takes the lead to set up first plant in India to treat 100 tons/day sludge and produce manure using a fully automatic process.

Effect of low power ultrasonic radiation on anaerobic biodegradability of sewage sludge.
The effect of low power ultrasonic radiation on anaerobic biodegradability of sewage sludge was investigated. For this purpose, soluble substances and variation of microbial system of sewage sludge subjected to low power ultrasonic radiation were tested. The well known hydromechanical shear forces and heating effect of low frequency ultrasound plays a major role in the sludge pre treatment proc...

Surface waters to be used as resource for drinking water, waste water and sludge produced in treatment processes are very complex media containing soluble, colloidal and particulate matter. Apart from inert or dead matter the colloidal and particulate phase is mainly composed by organic bio-particles (viruses, bacteria, protozoa). Treatment processes like disinfection of potable water, hygienis...
متن کاملNOTE / NOTE Release of phosphorus from sewage sludge using microwave technology
A novel microwave treatment of sewage sludge was developed as part of the ongoing studies for enhancing the recovery of phosphorus from municipal wastes. The microwave treatment provided a rapid and efficient process to release phosphate from sewage sludge. By using the microwave treatment for only 5 min, up to 76% of the total phosphate in the sludge could be released into the solution. No che...
متن کاملEffect of Temperature-increase Rate and Terminal Temperature on the Solubilization of Sewage Sludge using Microwave Irradiation
Solubilization of sewage sludge creates favorable conditions for anaerobic microorganisms to produce biogas. In this paper, we quantify the effect of heating pretreatment on the degree of solubilization of sewage sludge. The pretreatment process was carried out using a lab-scale industrial microwave unit (2450 MHz frequency). Response surface analysis was applied to determine the combination of...
متن کاملOverview of Bio-Oil from Sewage Sludge by Direct Thermochemical Liquefaction Technology
Sewage sludge is an unavoidable secondary pollution produced in the process of sewage treatment. At present traditional methods of treating sludge (e.g. landfill, incineration or land application) have some disadvantages and shortages. Direct thermochemical liquefaction of sludge is a new treatment method, which has the advantage of both treatment and energy recovery. Research progress and appl...
