Perchlorate (ClO₄¯) ion removal from water

Perchlorate is poorly abundant on earth, except combined with sodium nitrate mineral in some specific arid areas. Natural perchlorate is extracted to produce fertilisers. Perchlorate is intensively used in the formulation of explosive propellant for various explosives and weapons. To cover this strategic need, perchlorate is produced industrially. Perchlorate Molecular structure of perchlorate. Perchlorate is…

Mercury (Hg⁰ and Hg²⁺) removal from water

Introduction Sites contaminated with mercury are the result of a range of anthropogenic practises including industrial activity, mining and waste disposal. Contaminated sites may be impacted by a single substance or a highly complex mixture of chemicals and metals depending on the source of the contamination. Mercury poisoning can result from exposure to water-soluble forms…

Landfill Leachate – Jacobi Carbons Improves & COD Removal Process

Introduction The properties of land fill leachate varies widely in composition depended on different factors such as the age of the landfill and the type of waste that is stored in the landfill. Water percolating through the waste will promote the micobiological decomposition of organics. This digestion process rapidily use up any available oxygen creating…

Mobile Filters + Activated Carbons For Sugar Syrup Taste & Colour Treatment

Mobile Filters + Activated Carbons For Sugar Syrup Taste & Colour Treatment

The Problem Liquid Sucrose or sugar produced from beet or, occasionally, cane sugar can contain different taste or colour compounds. To combat this, a granular activated carbon process was developed using mobile filters to produce colourless and transparent liquid sucrose solutions with a neutral, sweet taste, free from any off-flavours. Application Information Liquid sucrose stream…

Soil remediation success

Soil Remediation – New Building Mercury Removal

The Problem During commissioning stages, mercury was detected in the air of a newly constructed building. Being set on a former light bulb production site, the link was quickly made between historical mercury contamination of the soil and the previous use of the site. Analyses of soil samples also showed contamination of other heavy metals,…

Biogas treatment

Biogas – How to purify biogas?

Biogas is produced by an anaerobic digestion or fermentation of biodegradable organic matter. This process can be done under controlled conditions in digesters or can happen spontaneously in landfill sites. Different types and mixtures of organic feedstock are used in digesters such as manure, energy crops, household waste, sewage sludge, industry waste. The produced biogas…

Styrene emissions control

Styrene Emissions Control – Reduction of styrene emissions during filling of storage tank

Introduction Styrene is a monomer that is used to produce a wide variety of plastics. During storage of styrene and manufacture of these plastics, emissions of styrene can occur causing concerns of exposure for workers and release to the environment. Case study: Reduction of styrene emissions during filling of storage tank Styrene can be transported…
