Knowledge of particle sizes and the size distribution of a powder system is a prerequisite for most production and processing operations. Particle size and size distribution have a significant effect on the solubility rates, mechanical strength, density, electrical and thermal properties of the finished object.
Significant production losses can be incurred due to high rejection rates if size and size distribution of powders being used in a process are not adequately controlled. In most instances powder suppliers provide size and size distribution information, but that information needs to be checked for quality control purposes. In certain processing operations, powder size and size distribution may have to be monitored at different stages of a processing operation for suitable process control. Powder size and size distribution can be determined using numerous commercially available instruments. Most instruments operate in a batch mode of analysis. There are few instruments that can be used in a continuous mode.

Silt is composed by suspended particulates of all types that accumulate on the membrane surface. Sources of silt are organic colloids, iron corrosion products, precipitated iron hydroxide, algae, and fine particular matter. Silt Density Index testing is a widely accepted method for estimating the rate at which colloidal and particle fouling will occur in water purification systems, especially using reverse osmosis (RO) or Nanofiltration membranes.
SDI is a measurement of the fouling potential of suspended solids. It’s not measuring the quantity of particular matter, since the size, shape vary. Turbidity is a measurement of the amount of suspended solids. They are not the same and there is no direct correlation between them. In practical terms however, the membranes show very little fouling when the feed water has a turbidity of < 1 NTU. Correspondingly the membranes show very low fouling at a feed SDI of less than 5.
The SDI test is used to predict and then prevent the particulate fouling on the membrane surface. Other names for it are the Kolloid-Index (KI) or the Fouling-Index (FI). The test is defined in ASTM Standard D4189, the American Standard for Testing Material.
It measures the time required to filter a fixed volume of water through a standard 0.45µm pore size microfiltration membrane with a constant given pressure of 30 psi (2,07 bar). The difference between the initial time and the time of a second measurement after normally 15 minutes (after silt-built up) represents the SDI value. At All Chemical we can test Silt density Index.

Soil is a critical resource in agriculture, ensuring the health of crop growth and livestock. At All Chemical we can test the well-being of your soil for an affordable price. The comprehensive testing and analysis will measure all elements of the soil, such as the pH levels, phosphate, sulphate and nitrates. Also, we will test possible diseases that would infect the crops, such as dieback.
Field pH test (pHF) measures the existing acidity of a ‘soil:water’ paste, and is therefore used to help identify if Acid Sulfate Soil (ASS) are present.
Field pH peroxide test (pHFOX) is used to indicate the presence of iron sulfides or PASS. If sulfides are present a reaction will occur.
Our interpretation of the results that come out of the testings and analysis will help you understand the current state of your soil. We will provide you with excellent advice on how to improve and maintain the health of your soil.
