How & Why We Measure Suspended Solids

by Partech (Electronics) Ltd.  (Jul. 10, 2016)

In case you weren’t sure, Suspended Solids is simply a density measurement used to describe exactly how much waste sludge and particles are in the water, and is measured in milligrams per litre (mg/l), grams per litre (g/l) or percentage solid (%). 1000mg/l = 1g/l = 0.1%. It is used to calculate the amount of material, or load, in a ...

Q&A: OMI’s Dr. Laura Haupert Discusses Eco-Friendly Odor Solutions for Landfills

by OMI Industries (OMI)  (Jun. 21, 2016)

The waste management arena is continually challenged when it comes to fighting odors, which often become a major nuance for neighbors. Landfills all throughout the U.S. also have to contend with finding the right odor-abatement solutions that are both effective, and safe for employees and surrounding communities. In the following “Clearing ...

Evaluation of the energetic potential of sewage sludge by characterization of its organic composition

by IWA Publishing  (Apr. 15, 2016)

The composition of sewage sludge and, thus, its energetic potential is influenced by wastewater and wastewater treatment processes. Higher or lower heating values (HHV or LHV) are decisive factors for the incineration/gasification/pyrolysis of sewage sludge. The HHV is analyzed with a bomb calorimeter and converted to the LHV. It is also ...

Determining anaerobic degradation kinetics from batch tests

by IWA Publishing  (Feb. 26, 2016)

Data obtained from a biomethane potential (BMP) test were used in order to obtain the parameters of a kinetic model of solid wastes anaerobic degradation. The proposed model considers a hydrolysis step with a first order kinetic, a Monod kinetic for the soluble organic substrate degradation and a first order decay of microorganisms. The ...

State Aims to Modernize Mindsets Along with Trash Policies, Facilities

by Blue Sphere Corporation  (Feb. 24, 2016)

By July 1, 2016, the Department of Energy and Environmental Protection (DEEP) is set to revise the state-wide solid waste management plan to include a strategy to divert, through source reduction, reuse and recycling, 60 percent of solid waste generated in Connecticut after January 1, 2026. That figure is more than double the waste currently ...

Flux-step method for the assessment of operational conditions in a submerged membrane bioreactor

by IWA Publishing  (Feb. 8, 2016)

A flux-step method was used for monitoring the pressure variation in a solids separation membrane at different operating conditions. A submerged membrane bioreactor pilot plant, used during the short-term tests, was used to purify actual restaurant wastewater. The influence of membrane backwash and relaxation on the variation of pressure ...

Effect of sodium salt on anaerobic digestion of kitchen waste

by IWA Publishing  (Jan. 22, 2016)

The effect of different sodium salt concentration on anaerobic digestion of kitchen waste was investigated. The methane production performance, the corresponding methane production model and sodium salt inhibition model were studied, and the degradation efficiency was analyzed. With the increase of sodium salt concentration, the methane yield ...

Thermal plasma processing in the production of value added products from municipal solid waste (MSW) derived sources

by Advanced Plasma Power (APP)  (Sep. 14, 2015)

Abstract The disposal of Municipal Solid Waste (MSW) is an increasingly difficult challenge for communities. Advanced thermal treatment (ATT) technologies, such as Gasplasma®, have been specifically developed to effectively utilise wastes to generate clean electrical power. An added beneficial feature of this process is the conversion of ...
