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.

 

 

QUICKSOLV Metering Station

The QUICKSOLV metering station is a compact dissolving and metering station with a usable volume of approx. 1 m3.
The station operates according to the principle of saturated solutions and is loaded manually with up to 25 bags of QUICKFLOC S (625 kg).


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.

 

The Carbonate-bicarbonate Equilibrium in Biological Sewage Treatment

Disruptions caused by bulking sludge, floating sludge or froth often occur in connection with elevated carbon dioxide production and accumulation. A chemical equilibrium, dependent on the pH value and temperature, exists between the carbon dioxide content and the acid capacity of waters.

Technical Information 3.05 describes different possibilities for eliminating the causes of this problem, rather than just treating the symptoms (e.g. bulking sludge). Innovative processes are also presented.

 

 

Aspects of Operational Safety in Municipal Waste Water Treatment

Municipal sewage treatment plants are characterized by constantly higher purification efficiencies during the operational stage. Whereas suspended waste water components can be separated by flocculation processes, dissolved nutrients and impurities are converted into other chemical compounds which can later also be removed mechanically from the waste water.

In this information, possible causes and countermeasures are discussed below.

Operational safety

The necessary requirements in order to meet the high demands on the purification efficiency of sewage treatment plants are often accompanied by bulking sludge events, flock output and poor sludge dewatering. In combination with targeted measures, KRONOS iron salts can optimize the cleaning processes and thus stabilise sewage treatment plant operation.
