Adsorbent grade resins are chelating resins that remove specific irons from a mixture of ions. It contains high surface area and unique pore structure, which make them suitable for applications such as separation of non-polar organic solutes from polar solvents.

Alkalinity Control in most invert emulsion mud is obtained by the addition of common calcium hydroxide or in calcium oxide. The use of a calcium base is particularly relevant when tall oil fatty acid soaps are in use. Oil-base muds do not suffer from the problems of hydrogen sulfide or carbon dioxide contamination that can occur in a water base fluid. However, such contamination in an oil base mud will show itself as the increased addition rate of lime to maintain alkalinity.

Anaerobic digestion is the process in which the microorganisms break down the organic materials in an enclosed vessel with out oxygen supply. It is the harnessed and contained, naturally occurring process of anaerobic decomposition. This procedure helps in treating the waste, produce biogas that can be used to power electricity generators, provide heat and produce soil-improving material.

The anion exchange resins are commonly used resin. It contains hydroxide ions and are divided into strong and weak base classes. These are used to remove negatively charged ions, such as SO2-4. Anion exchange resins are generally lower in their exchange capacity and durability than cation exchange resins and are seldom used for industrial separation.

Arsenic Remover works on adsorption principle and is able to reduce arsenic content of water below drinking water limit values selectively. It employs a simple process that flows pressurized water through a fixed bed pressure vessel containing the ferric oxide. As the contaminated water passes through the media, arsenic is adsorbed and removed to a level below 10mg/L. A typical arsenic remover for achieving a less than 10 ppb arsenic level for small-scale municipal water supplies requires an average pressure-drop of about 3 pounds per square inch (psi).

Biodegradable Dynamic Descaler is a safe non-toxic, biodegradable chemical used on the waterside of heat transfer equipment. Dynamic descaler is safe on copper, copper-nickel, bronze, brass, iron, stainless steel and rubber.

Biological remediation can be defined as any process that uses microorganisms, fungi, green plants or their enzymes to return the environment altered by contaminants to its original condition. Bioremediation may be employed to attack specific soil contaminants, such as degradation of chlorinated hydrocarbons by bacteria. An example of a more general approach is the cleanup of oil spills by the addition of nitrate and/or sulfate fertilizers to facilitate the decomposition of crude oil by indigenous or exogenous bacteria. There are a number of cost/efficiency advantages to bioremediation, which can be employed in areas that are inaccessible without excavation. For example, hydrocarbon spills (specifically, petrol spills) or certain chlorinated solvents may contaminate groundwater, and introducing the appropriate electron acceptor or electron donor amendment, as appropriate, may significantly reduce contaminant concentrations after a lag time allowing for acclimation. The process of bioremediation can be monitored indirectly by measuring the oxidation reduction potential or redox in soil and groundwater, together with pH, temperature, oxygen content, electron acceptor/donor concentrations, and concentration of breakdown products (e.g. carbon dioxide). This table shows the (decreasing) biological breakdown rate as function of the redox potential.

Biological sewage treatment systems process a sewage effluent. It improves the quality of sewage wastewater before it is released back into drain fields and the environment. There are two types of bacteria used for biological sewage treatment systems and are contained in the sewage. One type is an anaerobic bacterium, which does not require oxygen for metabolism. The second type of bacteria is aerobic, which requires oxygen for their respiration and synthesis process. It is used with micro filtration. A biological sewage treatment system is used for conventional and in-ground pools.
