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.

 

Digester Gas Desulfurisation with Iron Salts

Anaerobic sewage sludge stabilization generates digester gas that contains not only high-energy methane, but also small amounts of hydrogen sulfide. During subsequent use, the latter corrodes the gas engines and pollutes the environment.

By precipitating the sulfur in the form of FeS, the use of iron salts prevents dissolved hydrogen sulfide from passing from the digested sludge into the gas phase. This results in significant cost savings, reduces the maintenance effort and prolongs the service life of the gas engines.

 

Water treatment | Municipal sewage purification | Digester gas desulfurisation

Anaerobic sewage sludge stabilization generates digester gas that contains not only high-energy methane, but also small amounts of hydrogen sulfide.

This causes corrosion in the plant during subsequent gas processing and use. Furthermore, catalysers in gas purification can also be damaged.
