Kits, rules & graphs

OiEau develops technical kits to support the design or operation of water and sanitation structures. These are available on request.

Self-monitoring kits

The Self-monitoring and Control Kit has been specially designed to monitor your wastewater treatment plant of less than 10,000 population equivalents over one year.

It allows you to carry out the main weekly tests necessary for the operation of a plant: clarity, search for sludge film, recirculation, decantation, ammonia, nitrate, permanganate oxidability, phosphate (optional).

A refill kit allows the analysis reagents to be renewed each year.

An educational booklet is supplied with the case.

Weight : 6.2 kg - Dimensions : 51 x 41 x 18 cm.

Calculation rules Drinking water & Sanitation

Whether you are working in the office or in the field, the drinking water slide rule, which can be used for all materials from 20 mm to 1200 mm diameter, will enable you to determine the pressure losses according to the roughness of the pipe and the flow rate to be conveyed.

The sanitation calculation rule can be used for all materials from diameter 110 mm to 1500 mm. It will allow you, for free surface flows, to determine the diameters of the pipes to be installed according to the flow to be conveyed and the slope available on the site, and the water heights in partially filled pipes.

Both are supplied with an explanatory note.

Etalon rules

Are you responsible for the operation, maintenance, control and validation of free-flow measurement systems?

Our practical and precise Etalon rule makes it very easy to set up, check and calibrate your flowmeters.

Carbon Graph for Classic Waters

In the office or in the field, this 50-sheet booklet will allow you to define the calcocarbonic balance of a water and to know its aggressive or scaling character, to calculate the treatment rates of the correction reagents and to follow the quality of the produced water.
