QUICKFLOC
QUICKFLOC S
Salts
QUICKFLOC in bulk form is delivered on dumper trucks that are preferably unloaded by rear dumping.
QUICKFLOC is stored and dissolved by the soaking method. The heart of the facility is an underground tank with acid-proof lining that simultaneously acts as a storage and dissolving tank. This soaking tank is designed to permit dumping and accommodation of at least one full delivery batch (e.g. 25 t).
TI 2.01 describes the fundamental structure of soaking tanks, as well as the storage and metering of QUICKFLOC.
Solutions
KRONOS iron salt solutions are ready-to-use precipitants and flocculants
Iron salt solutions are stored in acid-proof tanks that should have a useful volume of at least 20 m3 and comply with the official regulations regarding the storage of water-hazardous substances.
Metering diaphragm pumps are preferably used to withdraw the liquid products from the tank and transport them to the metering point.
Complete metering facilities are supplied in practice, including all suction- and pressure-side fittings and piping.
Notes on unloading of dangerous goods
Various rules and regulations apply when dealing with dangerous goods
Transport by road is governed by the German Ordinance on the Transport of Dangerous Goods by Road, Rail and Inland Waterways (GGVSEB/ADR). Within the GGVSEB, the recipient (e.g. the sewage treatment plant) and the unloader (employees of the sewage treatment plant) have a number of tasks and duties.
This information is intended to outline to you the essential obligations.
Phosphate Elimination with Iron Salts
By targeted use of iron salts, the phosphates contained in the waste water are precipitated as poorly soluble iron phosphates and transferred to the sewage sludge.
The necessary quantity to be added is governed by the phosphate content of the waste water, the required degree of elimination and the active-substance content of the precipitant. Chemical and biological phosphate elimination are often combined in practice.
TI 3.01 describes the chemical and technical background, and presents suitable iron salts from KRONOS ecochem.
Purification of Industrial Waste Water with Iron Salts
Iron salts are generally used as flocculants in the field of industrial waste water purification. Different KRONOS iron salt products are available for almost every requirement in terms of process, purification efficiency and coverage of demand.
The fields of application are as follows:
Emulsion cracking, suspension flocculation, decoloration, sulfide removal, chromate elimination, phosphate precipitation, arsenic elimination, cyanide detoxification and heavy-metal precipitation.
Decoloration of Waste Water from the Textile Industry by Reductive Precipitation and Flocculation with Ferrous Salts
The required reaction occurs if chemical-mechanical purification by precipitation and flocculation with bivalent iron salts is used to remove the modern dyes of the textile finishing industry. The Fe2+ ion serves as a reducing agent and flocculant, causing irreversible cleavage and elimination of the dye molecules.
Using Iron Salts to Remove Hydrogen Sulfide from Waste Water Collectors
Hydrogen sulfide, H2S, can be formed in the sewer system during the transport of waste water to the sewage treatment plant. Hydrogen sulfide is not only foul-smelling and highly toxic, but also has an extremely corrosive effect on metal and concrete. The release of H2S must be suppressed in order to protect people, the environment and the fabric of the sewers.
As a result of sulfide precipitation with iron salts, the sulfides occurring are already converted into poorly soluble iron sulfide in the aqueous phase.
