Taming taste and odor (T & O) problems in a water treatment plant

Taming Taste & Odor (T&O) Problems Some taste and odors are caused by mineral constituents in the water, e.g. excess chlorine and hydrogen sulfide. However the majority of taste and odor are the result of biologic activity. Spring turnover of lakes and algal blooms are responsible for Blue-green algae (Cyanobacterium), Green algae and diatoms that introduce filter clogging organisms ...

Sequencing Batch Reactor Versus Continuous Flow Process for Pilot Plant Research on Activated Sludge

The objective of this article is to compare the advantages and disadvantages of the sequencing batch reactor (SBR) versus the more conventional continuous flow reactor (CFR) setup for pilotplant studies. The SBR process can offer many superior features for research applications. The control of operational conditions is more reliable, precise and versatile. Data collection by sampling and on-line ...

Treatment of odour containing hydrogen sulphide released from pharmaceutical wastewater treatment plant with SBR process by bio-trickling filter

In order to check the removal efficiency of odour containing Hydrogen Sulphide (H2S) from Sequencing Batch Reactor (SBR) process at lower temperature, deodorisation experiment was carried out for four months at pharmaceutical wastewater treatment plant in winter by the bio-trickling filter packed with ZX01 stuffing. The results suggested that the removal efficiency of H2S was higher than 98% and ...

Corrugated Sheet Plant

The previous wastewater treatment was composed of the following chemicals: an acidic coagulant, caustic for pH adjustment, and an anionic polymer made down to 1% solution. The facility used 3-4 gallons of coagulant, 2-3 gallons of caustic, and 2-3 gallons of anionic flocculant (at a 1% solution) at a cost of $50/batch. The operator stated that they had low solids, they tended to overdose which ...

Floating treatment wetlands for domestic wastewater treatment

Floating islands are a form of treatment wetland characterized by a mat of synthetic matrix at the water surface into which macrophytes can be planted and through which water passes. We evaluated two matrix materials for treating domestic wastewater, recycled plastic and recycled carpet fibers, for chemical oxygen demand (COD) and nitrogen removal. These materials were compared to pea gravel or ...

Treatment of Sludge Return Liquors: Experiences from the Operation of Full-Scale Plants

ABSTRACTMore stringent effluent criteria with regard to nitrogen call for improved nutrient removal techniques in wastewater treatment plants (WWTPs). Besides optimisation of the liquid treatment train of the plants, over the last years, attention has increasinly centred on the problem of return flows from sludge treatment. Depending on sludge handling and treatment, some 15 to 25 % of the ...

Wastewater Treatment Process

The wastewater treatment process is complex and critical to civilization. In simplest terms, wastewater is water that has been mixed with waste matter. Wastewater can be classified as domestic, municipal, or industrial based upon the source of generation. For instance, domestic wastewater comes from everyday liquid waste, including water used to flush the toilet, to shower, or to wash dishes. ...

Grease waste and sewage sludge co-digestion enhancement by thermal hydrolysis: batch and fed-batch assays

Grease waste (GW) is an adequate substrate for sewage sludge co-digestion since, coming from a waste water treatment plant, it has a high methane potential (489 NmLCH4/gVSin); however, no synergistic effect takes place when co-digesting with 52%VS grease. Conversely, thermal hydrolysis (TH) improves the anaerobic digestion of GW (43% higher kinetics) and biological sludge ...

Treatment of iron(II)-rich acid mine water with limestone and oxygen

The main components of acid mine water are free acid, sulphate, and Fe2+. Limestone is the most cost-effective alkali that can be used for neutralization. The purpose of this investigation was to identify conditions where Fe2+ is removed with limestone and simultaneously oxidized with oxygen to Fe3+, in a polyvinyl chloride pipe under pressure. Gypsum ...
