Concentrations of organic wood preservatives in wood chips produced from wood wastes
We investigated the concentrations of wood preservatives in the wood chips produced in wood-waste processing facilities in 1988, 1998–1999, and 2001–2002. Among the wood preservatives used in the past in Japan, halophenols, including PCP, chlordane, and chlorpyrifos, had comparatively high detection rates and high average concentrations in the wood chips produced in 2001–2002. Aldrin and endrin ...

Evaluation of passive reduction of nitrate from greenhouse effluent by planted bioreactors
A number of pilot-scale gravel and wood-chip hybrid bioreactors planted with select species, together with unplanted units, were evaluated for their nutrient removal capabilities from the typical greenhouse effluent with high levels of nitrate and salts. Two levels of nutrient solution (high and low loading: HL/LL) were prepared to simulate the typical characteristics of the greenhouse ...

The Benefits of Using Rubber Playground Mats
After you have raked and swept the playground area, you might consider putting a soft rubber mat for flooring which is safer for children to play on. The rubber playground mats provide a little bounce, so if the child accidentally falls from the swing or the slide to the ground, he will not get hurt. There are many cheap playground floorings available in different colors and shapes. They are easy ...

Moisture measurement with M-Sens 2 - Case Study
Application A manufacturer of wood pellets processes raw material such as planing chips or wood chips (wood waste) to make wood pellets. After delivery of the wood waste, it is cleaned from extraneous material like metal and stones by a separator. Afterwards the material is crushed by a hammer mill and then dried. The crushed material is then transported by a conveyor belt through a 90 °C ...

Denitrification in wood chip bioreactors at different water flows
Subsurface drainage in agricultural watersheds exports a large quantity of nitrate-nitrogen (NO3–N) and concentrations frequently exceed 10 mg L–1. A laboratory column study was conducted to investigate the ability of a wood chip bioreactor to promote denitrification under mean water flow rates of 2.9, 6.6, 8.7 and 13.6 cm d–1 which are representative of flows entering subsurface drainage tiles. ...

Biodegradation of methane and halocarbons in simulated landfill biocover systems containing compost materials
The attenuation potential of methane (CH4) and of selected volatile organic compounds (VOCs) was compared in four types of compost materials using dynamic flow column experiments over a period of 255 d. Garden waste compost mixed with wood chips showed the highest steady-state CH4 oxidation rate (161 g m–2 d–1), followed by a commercial compost product Supermuld (110 g m–2 d–1). In the column ...

The simple, effective and economical treatment of odourous emissions
The odours from an anaerobic digester and a waste handling depot were fed to two large biofilters with wood chip packing. The seeding of the biofilters was carried out using a microbial product, BFL Odour Clean. For the initial seeding of the biofilter with microbial cultures a manual method of application was used. Careful application of the product to the entire filter bed is key to the success ...

Mesquite wood chips (Prosopis) as filter media in a biofilter system for municipal wastewater treatment
The biofiltration system over organic bed (BFOB) uses organic filter material (OFM) to treat municipal wastewater (MWW). This study evaluated the performance of a BFOB system employing mesquite wood chips (Prosopis) as OFM. It also evaluated the effect of hydraulic loading rates (HLRs) in order to achieve the operational parameters required to remove organic matter, suspended material, and ...

Granular Segregation: Why You Can’t Mix Materials in a Silo
From time to time, we meet clients who attempt to store mixed materials in a silo. Either the material is premixed or the client fills the silo with separate materials and assumes the materials will mix as they descend through the system. What they discover, however, is that the materials, whether they be wood chips or grains, do not remain uniformly mixed. The reason why this occurs has to do ...
