WASTEWATER TREATMENT: PHYSICAL AND CHEMICAL PROCESS BASIC CONCEPTS: In order to dispose off the waste water, it should meet some standards set by local authorities. Preliminary treatment of wastewater generally includes those processes that remove debris and coarse biodegradable material from the waste stream and/or stabilize the wastewater by equalization or chemical addi-tion. Describe some primary and secondary wastewater treatment methods. energy.Food industry wastewater treatment by physicochemical method using Zinc Sulphate, FerrousSulphate and Ferric chloride has been reported. Tertiary Treatment of Wastewater – Methods and Process Written by AOS Treatment Solutions on September 11, 2018. The food processing wastewater shows large variation in BOD/COD, total solids and suspendedsolids, oil and With the recent developments in technology, particularly the development of membrane processes and alternative disinfection processes for water and wastewater treatment, there is an increasing need for a common methodology to evaluate the reliability of alternative processes and treatment facilities that utilize different combinations of those processes. Waste water Treatment When effluent discharged into a river body such as lake, river or sea anumber of process occur like physical, chemical and biologicalcharacteristics of water change which cause loss of organism.The extent of damage depend upon type pf pollutant present in effluent.Non bio-degradable pollutant like mercury are most deadly as theyaccumulate in aquatic organism which lead to Biomagnifications.Large quantity of biodegradable waste can affect living organism in thewater bodies in which waste are discharged.areIt is necessary to treat effluent or waste water before discharging inwater body. it . | PowerPoint PPT presentation | free to view Wastewater Laboratory Basics sampling, ammonia, BOD, chlorine residual, fecal coliform, pH, solids IWEA Laboratory Workshop August 8, 2013.

WASTEWATER TREATMENT METHODS The treatment of wastewater is a relatively modern practice. • This presentation discusses the fundamentals of converting wastewater back to water – How do we (humans) interact with the hydrologic cycle. Much of the water used by homes, industries, and businesses must be treated before it is released back to the environment. Biological processes become more and more popular in wastewater treatment — even for the demanding conditions in the chemical industry. The treatment procedure are generally divided into threegroups-1. Wastewater derived from human activities in households such as bath, laundry, dish washing, garbage disposal, toilets etc is called as Domestic Wastewater which usually contains relatively small amounts of contaminants but even small amount of pollutants can make a big impact on environment. Petroleum wastewater from SOR is very difficult to treat with conventional treatment followed by classical physicochemical methods because it has high concentrations of recalcitrant organic material. Chemical treatment is now considered as a tertiary treatment that can be more broadly defined as “treatment of wastewater by a process involving chemical treatment”. 4. Wastewater treatment is a process used to remove contaminants from wastewater or sewage and convert it into an effluent that can be returned to the water cycle with acceptable impact on the environment, or reused for various purposes (called water reclamation).
