“…The analysis of turbidity of the water sampled from the three residential areas produced a turbidity of 0.00 for all three samples. This supports the low pH and low chlorine residue in the sampled water, as in all processes in which disinfection is used, the turbidity must always be low (Maciel et al, 2021). In addition, analysis of TDSs and TSSs for the water samples from the three residential areas produced results which were within the WHO's guidelines for drinking water, as indicated in Table 2.…”

Water quality analysis is an essential component of water supply globally. This study analyzed drinking water quality at the tap in the Wa Municipality of Ghana. Bacteriological, physicochemical, aesthetic, and some chemical parameters of raw, treated and tap water was analyzed. The analysis showed that drinking tap water has a good quality and was satisfactory according to the World Health Organization’s (WHO) guidelines for drinking water. However, an assessment of consumers’ perception of water consumption profiles revealed that 25 % of the respondents claimed that the water quality was bad and had some taste that may be attributable to the long period of water storage. Therefore, it is recommended that the post chlorination dose should be increased to ensure the disinfection requirements and avoid any post-treatment contamination.

“…13 UVC irradiation using photons of light from the 100-280 nm region of the electromagnetic spectrum, an effective and non-contact method for inactivating viruses and bacteria, has been widely used for disinfecting food, water supplies, public facilities, and medical instruments. [14][15][16][17] The UVC range shows the strongest antiviral and antibacterial activity among the three applied UV wavelength ranges, including UVA (315-400 nm) and UVB (280-315 nm) ranges. 18 The available scientific literature shows that three UVC range subsets (i.e., 207-222 nm, 19,20 254 nm, 21,22 and 260-280 nm 23,24 ) are considered to be optimal for pathogen disinfection.…”

“…The condition and ease of maintenance of the equipment and communications used have a great influence on the quality and cost of water treatment [2,3,7,12,14]. From this point of view, the most effective are modular cleaning systems, which are a system of sequentially installed filters [15][16][17].…”

Scientists from different countries are engaged in the development of new or improvement of existing water purification technologies. At the same time, not enough attention is paid to the development of equipment for water purification and technologies for their manufacture. The article presents a model of a universal filter housing for cleaning liquids from solid particles. Mechanical filters of cartridge or bag type can be used as filter elements. The main supporting element of the filter housing is a thin-walled cylindrical flask. The use of rotary rolling in the process of manufacturing a cylindrical flask makes it possible to reduce the negative effect of welded seams and increase the strength of the cylindrical shell. The results of experimental studies on assessing the effect of the relative deformation value along the wall thickness during rotary rolling of steel cylindrical shells on their strength and stability are presented.
