Section One
Organic Floc
Organic Floc acts in colloidal systems neutralising charges and creating electric bonds between particles, making them unstable, producing flock and causing their sedimentation.
Organic Floc is essential a bio-based cationic natural flocculant. It acts as a coagulant, flocculant, and auxiliary flocculation agent.
The product has a broad spectrum of applications by previous trials (jar-test) with exceptional reduction traits on extremely high turbidity water. The most considerable difficulty is the treatment of water polluted with finely divided particles, which can be untreated sewage, heavy metal ions, and non-biodegradable pesticides or naturally occurred organic and mineral compounds.
Organic Flock acts in colloidal systems neutralising charges and creating electric bonds between particles, making them unstable, producing flock and causing their sedimentation.
Organic Floc does not alter the pH of the water being treated because it does not consume the environment’s alkalinity and at the same time effective in a pH schedule from 4.5 to 8.0
Applications
Wastewater of metallurgy, pulp and paper, tanneries, food, and chemicals industries, in primary or secondary treatment plants. Petrochemical waste waters, on the secondary treatment of integrated systems.
Drinking water treatment on conventional and compact treatment plants
Advantages
Ready-to-use that is safe to store
No decomposition products
Odorless
No dangerous substances
Packing
Organic Floc is packed in easy-to-handle 25 kg bags.

Purifier For Cyanide Detoxification
Cyanides (CN) are beneficial compounds that have widespread uses industrially. However, to avoid the environmental release of highly toxic cyanide species into the environment, it is necessary to use effective techniques to remediate cyanide-containing wastewater’s
Purifier – the powerful non-chlorine oxidizer – rapidly oxidizes cyanide ions in industrial waste streams. The excellent environmental and safety profile and ease of use of Purifier chemistry makes the powder product an attractive choice for a wide variety of cyanide detoxification applications.
Purifier compound reacts rapidly with waste streams with complex mineralogy. Cyanides, thiocyanates, and weak acid dissociable (WAD) metal complexes are degraded at ambient temperature within minutes. The process is selective, efficient, and operationally simple, requiring low capital investment. ThePurifier product has an excellent safety profile for storage, handling and transport, and results in more environmentally favourable end products.
Advantages of the Water Purifier process
Alternative oxidation methods have several disadvantages as compared with Purifier chemistry. Alkaline chlorination has environmental disadvantages due to the formation of toxic chlorinated by-products, meaning that additional dechlorination processes may be required. The hydrogen peroxide process can consume high quantities of copper sulfate and has slow reaction kinetics. Ozone treatment can have high operational costs, is limited by poor solubility and is a toxic gas, which must be generated in situ. The sulfur dioxide and air processes are operationally complex.
Water Purifier cyanide oxidation chemistry
Cyanide ion oxidation: HSO5– + CN– OCN– + HSO4– Thiocyanate ion oxidation: 4HSO5– + SCN– + H2O OCN– + 5HSO4– + H+ During processing the pH should be maintained above 9 to avoid toxic HCN gas formation. Cyanate can be further oxidized to nitrogen and carbonate by using Purifier compound in excess.
Proven chemistry
The following laboratory trial illustrates one example of the oxidation efficiency of Purifier compound for cyanide remediation. Plant pulp, with an initial sodium cyanide concentration of 42 mg/ml, was treated with Purifier powder in an amount sufficient to provide molar ratios of 1:1 to 3:1 Purifier:CN-(equivalent to 13-gram Purifier powder per gram of cyanide). At least a 60 % reduction occurred within 5 minutes, while addition of 5 mg/l Cu² (Copper sulfate dosed at 2.5g/l) catalyst further enhanced oxidation to achieve >99% cyanide destruction within 5 minutes

Water Purifier For Pulp
OVERVIEW
The Pulp and Paper industry is highly dependent on water resources, and there are more stringent regulations on effluent discharges to receiving waters, particularly for bleached pulp mills. In most cases, these regulations concern mainly AOX concentrations, biotoxicity, and COD levels in the final discharges. Furthermore, the pulp bleaching process involves several bleaching procedures using chlorine and other chemicals to remove residual lignin and remove chromophore groups. Chlorinated compounds increase the BOD and COD of effluents causing environmental problems. Purifier for Pulp & Paper offers a great solution to all these problems.
Bleached, chlorine-free kraft pulp is categorized as either totally chlorine-free (TCF) or elemental chlorine-free (ECF). TCF pulp is produced with pulp that has been bleached by using ozone and hydrogen peroxide, or that has not been bleached at all.
In the pulp and paper industry chlorine dioxide, hydrogen peroxide, sodium peroxide, sulphur dioxide, sodium bisulfite, and sodium hydrosulphite are commonly used. Synthetic fibres are bleached with either oxidizing or reducing agents, depending on their chemical composition.
Unlike chlorine-based repulping agents, Purifier compound does not produce absorbable organic halogens (AOX) or other chlorinated organics. It also does not degrade the fibre or darken mechanical pulp. It is easier to handle and does not require any additional storage or delivery equipment. Under optimum conditions, Purifier compound reacts rapidly, thereby reducing the repulping time and increasing the productivity of the pulper. It is effective under commonly found pulping conditions. Purifier compound can also be used to repulp certain coloured papers, including decolorization of dyes. Dye destruction generally requires use of an additional reactant which is added to the repulper separately. Purifier compound can be delivered to the repulper either in specially designed repulpable bags or by using an automated system fed from a bulk bag of Purifier compound. Either method can provide accurate dosing to the repulper and minimizes handling by operating personnel.
As is well known, the purpose of pulp bleaching is to enhance the brightness and cleanliness of pulp by removing coloured substances therefrom or by changing such constituents to achieve the desired end brightness. Pulp is bleached to a certain level of brightness which depends on the use of the pulp. An important aim of the bleaching process is to keep the brightness level of the bleached pulp as even as possible.
The most significant coloured substance of chemically manufactured pulp, i.e., chemical pulp, is residual lignin, which is to be removed from the pulp as completely as possible, in other words pulp is bleached in a manner exclusively removing lignin.
It goes without saying that a bleaching process has to be implemented in an as economic and environmental-friendly manner as possible. The bleaching process is responsible for most of the water consumed and the waste water produced by a sulphate cellulose mill, which makes the role of the bleaching process even more important as regards the environmental load caused by the entire mill. Therefore, the environmental load caused by the chemicals used in bleaching is to be reduced. Such chemicals are also responsible for incurring considerable raw material costs. It is thus extremely important to administer chemical dosages appropriately in order to be able to produce pulp in an environmentalfriendly and economical manner.
Purifier is particularly profitable because each kg of the product replaces between 2 and 4 kg of pure chlorine dioxide. In addition, the treatment reduces the generation of wastewater and the consumption of fresh water, thus complying with environmental regulations.
THE BENEFITS OF PURIFIER FOR PULP & PAPER:
• Lower bleaching costs. In addition, a significant reduction in the effluent discharge load.
• Improved brightness stability.
• Low OX content
