The dewatering ability of biosolids was improved by elec. arc treatment prior to addn. The method uses combined effects of UV radiation, pulsed mech. shock waves, and ionization of H2O to alter the surface properties of microbial cells. Improved dewatering is due to elec. by free radicals, and collapse of biosurfactants and biopolymers. Do you want to read the rest of this article?

Biosolids are divided into two classes on the basis of pathogen content: Class A and Class B (Information Box 2. )

Biosolids can be defined as stabilized organic solids derived from sewage treatment processes (mostly resulting from the biological treatment of wastewater) which can be managed safely to be used beneficially for their nutrient, soil conditioning, energy, or other values (Shammas and Wang, 2008). From: Environmental Materials and Waste, 2016. Biosolids are divided into two classes on the basis of pathogen content: Class A and Class B (Information Box 2. ). Class A biosolids are treated to reduce the presence of pathogens to below detectable levels and can be used without any pathogen-related restrictions at the application site.

Biosolids is a term used for several types of treated sewage sludges that can be used as soil conditioner. Treated sewage sludge has long been used in agriculture. Biosolids may be defined as organic wastewater solids that can be reused after suitable sewage sludge treatment processes leading to sludge stabilization such as anaerobic digestion and composting.

This study investigates the effects of sewage sludge and compost usage o. .- CEC cation exchange capacity, EC electrical conductivity, OM organic matter.The application of biosolid as a fertilizer in agricultural cultivation is a common practice in many countries. This study investigates the effects of sewage sludge and compost usage on soil chemical properties and Zea mays nutrition in comparison with those of iron and manganese sulfate solution. CEC cation exchange capacity, EC electrical conductivity, OM organic matter. The short-term (one-time) nature of biosolid application in these experiments may have contributed to the lack of a significant effect on these elements. Trace metals in biosolids are generally strongly sorbed to the biosolid matrix.

The effect of the electric current of more than 25 mA leads to paralysis of the muscles . An arc burn is caused by the action of the electric arc creating a high temperature.

The effect of the electric current of more than 25 mA leads to paralysis of the muscles of the respiratory system, resulting in a possible asphyxia. With the further amperage increase, a cardiac fibrillation occurs. Electric burns – are the most common electrical injuries, occurring as a result of a local exposure of the current to the tissue.
