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.

 

 

Granules

FERROGRANUL products are dried, free-flowing ferrous sulfates that can be handled in the same way as conventional bulk materials.

Tower silos of all kinds with a useful volume upwards of approx. 30 m3 are open to consideration for receiving and stocking the delivered granules.

 

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.

Reduction of chromium VI in residues such as ashes, slags and dusts

Chromium was first identified as a chemical element in 1797. The name is derived from the wide variety of color of its compounds (from Greek χρωμα chroma “color”). In nature, it only rarely occurs in elemental (solid) form, such as in meteorites and few rocks. The most important chrome-containing mineral is chromite, FeCr2O4.

Special applications | Chromate reduction in residues

The toxicity of chromium VI has led to extensive legal restrictions and regulations when dealing with materials contaminated with it.

In addition to a number of absolute bans on use, there are restrictions in many areas due to limit values for chromium VI, such as the classification of a waste in a landfill class or the placing on the market of incineration ashes as a component of fertilizers. In addition, chromium VI is highly significant in the field of occupational health and safety with regard to many (filter) dusts and residues in industrial processes.
