Total dry solids

YK-1 and YK-2 are the lot number of compost samples manufactured by Yahata Bussan Co., Ltd. Compost was dried in a drying oven at 105 °C for 10 hrs. Total dry solid was burnt to ashes at 550 C in an electric furnace. pH was determined on 1 5 compost.water suspension with a pH meter manufactured by TOA. Carbon content was measured by the Tyulin-method. Total nitrogen was measured by the Devarda s alloy-sulphuric acid method. 

Compost quality No negative effects on density, total dry solids, volatile solids, salt content, pH, total nitrogen, ammonium nitrogen, phosphorus, magnesium and potassium eco-toxicity effects on 2 crop plants. 

A 200.0-mL sample of water was filtered through a preweighed glass fiber filter. After drying to constant weight at 105 °C, the filter was found to have increased in mass by 48.2 mg. Determine the total suspended solids for the sample in parts per million. 

Drying Fhiidized-bed units for drying solids, particularly coal, cement, rock, and limestone, are in general acceptance. Economic-considerations make these units particularly attrac tive when large tonnages of solids are to be handled. Fuel requirements are 3.3 to 4.2 MJ/kg (1500 to 1900 Btu/lb of water removed), and total power for blowers, feeders, etc., is about 0.08 kWh/kg of water removed. The maximum-sized feed is 6 cm (IV2 in) X 0 coal. One of the major advantages of this type of dryer is the close control of conditions so that a predeterminea amount of free moisture may be left with the solids to... 

Total Dissolved Solids (TDS)—Over 5,000 ppm can adversely affect thermal performance and may be detrimental to wood in the alternately wet/dry areas of the tower. 

Aliquots of each treatment (root exudate) were dried at 105°C to determine total dissolved solids. The pH of each treatment was measured. 

Salinity is defined as the concentration of total dissolved solids (TDS) in a solution, usually expressed in mg/L. The TDS concentration in water is usually determined from the weight of the dry residue remaining after evaporation of the volatile portion of the original solution. Groundwater may be classified into four salinity classes64 ... 

The multiple-hearth incinerator (Fig. 16-6) can accept sludges containing between 60 and 75% water. The operating costs run between 0.50 and 5.00 per ton of dry solids, with total costs between 8 and 14 per ton. Design information is given in reference 62. When the sludges contain more water, fluidized-bed incinerators are sometimes used. Their operating costs run between 11 and 21 per ton of dry solids and capital costs are 15/ton.6 See reference 63 for more details. All incinerators must have the proper air-pollution abatement devices attached. 

Sometimes, instead of incinerators, so-called oxidation processes can be used. In this context oxidation differs from combustion in that no flame is present and the temperatures are much lower. A high-pressure process (1,750 psi or 123 kg/cm2) that operates at a temperature of 525°F (275°C) has total costs around 33/ton of dry solids.62 Others operate at a pressure of around 600 psi (42 kg/cm2). They can treat sludges containing up to 99% water. 

Open vessel digestion (HF HC104) for ceramics, glass, rocks, and soil These acids should completely dissolve most materials. HF removes the silica (as volatile SiF4), which reduces the total dissolved solid content and therefore reduces interferences, and C104 produces perchlorates, which are soluble (but explosive if dried out). The use of hydrofluoric and perchloric acids therefore has considerable safety risks and requires specialized fume hoods, handling equipment, and safety equipment. The hydrofluoric and perchloric acids are removed by a later evaporation stage unless the analytical instmment and safety considerations have been specially adapted. 

For wastewater samples, a number of additional solid determinations are typically performed, including total dissolved solids, volatile solids, and settleable solids. Total dissolved solids are the total solids minus the suspended solids and are determined in a manner similar to total solids, but after filtering out the suspended solids. Thus, a volume of the filtrate is measured into the evaporating dish and the water evaporated in a drying oven. 

Pd = the dry mass density (mass of dry solids divided by the total volume of the soil/sediment specimen used in a leaching-column test) of the test specimen, and... 

In Fig.l the separation result is mentioned for a filter net of meshsize 0.78x0.78 mm. From Fig.l it is apparent that about 35% of the total faeces and urine is removed as a solid and that about 90% of the total dry matter is in the faeces. Also for a number of minerals, P205, CaO, MgO and Cu, it amounts to more than 90%. Nitrogen and potassium were separated in smaller amounts, about 60% and 40% respectively, being retained in the solid. 

Lindquist and Dias [26] have described a Zymark Py Technology System which automates and integrates four methods total dissolved sohds (TDS) dried at 180°C, TDS residue on evaporation (TOS-ROE) dried at 103—10S°C, total suspended solids (TSS) dried at 103-10S°C, and total sohds (TS) dried at 103-10S°C. Approved Environmental Protection Agency (EPA) or equivalent methods are used. A TurboVap Evaporator has been incorporated into the design to speed up the sample evaporation. 

Total Solids. The optimum total solids present in an anaerobic digester should normally range from 7 to 9 percent. Animal manure contains from 10 to 25 percent dry solids and may require dilution prior to loading into an anaerobic digester. 

At start-up, before any ethanol is generated by fermentation, the initial mass of yeasf (wafer plus yeast dry solids) in the bed is niy. Any ethanol accumulation in the bed is in excess of niy so fhaf af equilibrium the total mass in the bed (yeast plus ethanol) is niy -t m. A material balance for the bed mass is then... 

Oil content versus moisture content in dry basis for control slices fried at 120,150, and 180°C is shown in Figure 11.2. There is a clear effect of the frying temperature on oil uptake at moisture contents < 1 g water/g dry solid the higher the fiying temperature the lower the oil content -average values of 0.39, 0.35, and 0.30 g/g dry basis for 120, 150 and 180°C, respectively. Figure 11.3 shows kinetics of total oil (TO) uptake and their different fractions (PSO, STO,... 

Milk or skim milk is standardized to meet milk fat and total milk solids compositional requirements in the final dry milk product e.g., NFDM must contain <1.5% milk fat DWM must contain >26% and < 40% milk fat, and both must contain <5% moisture on an MSNF basis (CFR, 1982). Dry milk products must also meet U.S. Department of Agriculture and American Dry Milk Institute standards for titratable acidity, scorched particle content, solubility, and bacteria content. Product users may also have specialized requirements for color, flavor, and dispersibility.

Starting Material. A drum of concentrated, mixed, southern pine kraft black liquor was kindly supplied by the Canton, N. C. mill of the Champion Paper and Fibre Co. Analytical data for the liquor indicated 49.7% total solids and a methoxyl content of the oven-dried solids of 5.54%. The pH of the liquor as received was 12.3. (All melting points are uncorrected. Infrared absorption spectra were determined by Mr. Lowell Sell of The Institute of Paper Chemistry Analytical Group.)...
