Question 2

Clarified water storage tank

Accepted Answer

The clarified water storage tank is generally a cylindrical vessel made of steel, designed to collect the water coming from the clarifier. Its main function is to act as a storage and buffer volume, ensuring process continuity and stabilizing the outlet flow rates. For this reason, its dimensions are determined according to the capacity of the clarifier to which it is connected.The structure consists of an upper cylindrical section and a lower conical bottom. The latter is equipped with a discharge valve that allows the periodic removal of accumulated deposits and facilitates tank cleaning and maintenance operations.The clarified water transfer pumps draw the liquid from the cylindrical section, immediately above the conical part, ensuring efficient suction and proper feeding of the subsequent process stages.ModelDiameter(mm)Shell Height (mm)Cone Height (mm)Capacity(l)PRX-CWT-1700/4500170020005004000PRX-CWT-1700/6000170025005006000PRX-CWT-2200/160002200400050016000PRX-CWT-2200/230002200600050023000PRX-CWT-2200/300002200800050030000PRX-CWT-2200/4000022001000050040000PRX-CWT-2200/5000022001200050050000

Question 3

Flocculant solution preparation system

Accepted Answer

The flocculant solution preparation system enables the dosing and dissolution of the powdered product in a predetermined quantity of water.The flocculants used are organic anionic products based on polyacrylamide and must be prepared with clean water at a temperature between 10 and 40 °C, obtaining a final concentration of 0.1–0.3%.The mixing of water and powder is ensured by an agitator that guarantees a homogeneous solution; the mixture must be kept under agitation for at least 45 minutes to ensure proper preparation.The solution can be prepared either manually or fully automatically.The automatic system, manufactured in AISI 304 stainless steel, is available in a three-chamber configuration. In the first chamber, water and powder are automatically mixed; the solution then flows into the maturation chamber, where it is kept under agitation until the optimum characteristics are achieved. The third chamber is dedicated to solution storage and subsequent delivery by means of a dosing pump.For less complex applications, a two-chamber version is also available, combining ease of use with operational efficiency.

Question 4

Automatic flocculant dosing system

Accepted Answer

Optical flocculant calibratorThe automatic flocculant dosing system is designed to optimize the water clarification process, ensuring the correct use of the reagent under all operating conditions.Thanks to an optical calibrator, the system continuously monitors the characteristics of the water and automatically adjusts the amount of flocculant dosed. The adjustment is carried out by varying the rotation speed of the injection pump, increasing or decreasing the dosage according to the actual process requirements.This dynamic regulation helps reduce chemical consumption, improve clarification efficiency and lower plant operating costs. The result is a more stable, reliable and cost-effective treatment process, with optimized flocculant use even when the turbidity of the incoming water varies.
