Dosage Tanks and Bunds

Virtually all modern water treatment chemicals are supplied in liquid form.

Dependant on the application and the programme employed, the chemicals may need to be dosed "neat", i.e. in the concentration or mix they are supplied in, or they may require dilution with water.

Either way, storage of the chemicals is best undertaken in dedicated Dosage Tanks.Dosage direct from the container the chemical is supplied in is, of course, an option - but not a preferred one.

• Chemical containers usually preclude observing the level of chemical left. Thus unless level monitors are used it can be difficult to ascertain when chemical levels are low.
• When changing containers, risks in spilling chemicals are high due to taking out and changing over suction lines.
• It can be difficult to use the entire chemical volume in the container which can lead to wastage or handling hazards.

Thus we always recommend the use of Dosage Tanks for chemical storage and we offer a range of Dosing Tanks and Bunds manufactured from medium density polyethylene suitable for internal storage of a wide variety of chemical products, as part of an automatic dosing and control system.

Dosage tanks are available in 50, 100, 200, 500 and 1000 litre sizes.

They can be supplied in either natural (translucent) or black.

For ease of chemical addition a large filler hole with lid is provided and suitable storage of concentrated, diluted or mixed (to supplier's instructions) products can be achieved.

All tanks are graduated to facilitate monitoring of chemical usage. Metering pumps can be mounted on the top surface of the dosage tanks with suitable fixings (not supplied).

Dosage tanks should always be located in a suitable bund to ensure that any spillage of chemical is contained within a safe area.

Standard bunds are circular in shape and available in natural (translucent) or blue. They are designed to contain the nominal capacity of all the standard dosage tanks, i.e. 50, 100, 200, 500 and 1000 litre sizes.

All the tanks are for general purpose in an internal environment, protected from freezing conditions. The choice of tank is determined by the storage volume required.

Black tanks are intended for use with oxidising chemicals such as chlorine, sodium hypochlorite, chlorine dioxide solutions or other products which suffer degradation by UV light.

Health & Safety

It is a legal duty to comply with the Control of Substances Hazardous to Health Regulations relating to the mixing and handling of chemicals.

The contents of all dosing tanks should be clearly identified and Product Safety Information Sheets and Dosage Instructions should be displayed at the point of use.
